Make a "Marble" Table From Concrete W/ Torched Wood Base by Modustrial Maker in furniture

I am a DIY hobbyist who loves making things, especially with wood and concrete ( and recently, LEDs). Subscribe to my YouTube channel for more builds: https://www.youtube.com/c/ModustrialMaker Follow me on Instagram:
https://www.instagram.com/modustrialmaker/?hl=en Check out the Modustrial Maker website for more info on my builds: www.modustrialmaker.com


 made a coffee table top from concrete, that looks like marble (at least to me). The top is made using a glass fiber reinforced concrete (GFRC) ready-made concrete mix  , which is pre-cast in a melamine form. I separated out batches of different colored concrete (from white to dark grey), mixed them together in the form, and then swirled them together by hand to get the marble-like appearance.

I also used an ancient Japanese technique called “Shou Sugi Ban” to make the base for the coffee table. I used a modernized version of shou sugi ban, employing a propane torch to char the outside of the wood. The charred wood is natural way of protecting the rest of the wood, and when finished with a penetrating oil, such as Danish oil, provides a durable surface. This technique works well on any open-grained wood, such as Douglas fir, pine, and cedar. I used inexpensive 4x4 Douglas fir lumber from my local big box store.

Making a Powerful Generator From a Blender Motor DIY


In this instructable, i will teach you how to transform a 220 volts Blender motor into a powerful generator without any additional circuit.

Blender Motors are actually the universal Motors which are capable of operating at both AC or DC inputs.

High power DC Motors are really difficult to find at home but the Blender motors are easily available almost everywhere and from that point of view, this project is of great importance.

Since they operate at high voltage therefore they also generate high voltage of 200V to 300V.

Step 1: Requirements:

mobile charger/laptop charger
48 volts to 220 volts inverter
1-Universal motor
jumper wires
bulb connectors

Step 2: Connections:

The above Universal motor has four wires.Two wires both black in colour are for the armature while the other two wires black and red are for the field.

Now take a laptop charger and measure its output voltage with a multimeter. I have used a 19 volts laptop charger though you can use any voltage range from 5 volts which is for a mobile charger to 20 volts which is usually for the laptop chargers.

Connect the two output wires from the laptop charger to the field wires of the universal motor irrespective of the polarity.

Once you do that, the field winding gets activated.Now take an inverter and connect it to the armature terminals of the Universal motor.

To the output 220 volts or 110 volts side of the inverter, connect the load bulb.

Now take the plastic thread and wound it around the shaft of the Blender(universal) motor.

Step 3: Testing:

After your completed the previous steps, all you have to do is hold the Universal motor with one hand and pull the plastic thread as fast as you can with your other hand.

You should see your bulb glowing brightly.

The maximum voltage that i could achieve with the hand generation test was 122.8V DC as can be seen in the picture.

The maximum power that it can generate should be 200W though it depends a lot upon the mechanical rotation and the power fed to the field.

To understand it better please watch the video here. *

Why Are Ice Cubes Often Cloudy?

Tap water typically contains benign impurities such as lime, calcium, fluoride, nitrates, magnesium, and other organic elements. When water freezes, it hardens from the outside in, and those impurities are pushed into the center of the cube, causing the ice to have a cloudy appearance. However, boiling the water first will remove most of the impurities and provide clearer ice.

Ice, ice, baby:

Using bottled water that has been purified using a reverse osmosis process, or another type of distillation, will also improve ice cube clarity.

Cloudy ice is also related to how quickly the water is chilled. Most home freezers cool very rapidly, and tiny air bubbles (actually, dissolved air) get trapped before they can dissipate.

High-end restaurants use systems that freeze pure water slowly, in layers, so that air bubbles have plenty of time to escape.

Make a Powerful Generator From a Dead BLDC Motor

by omars2   in electronics


In this instructable, I'm going to teach you how to convert a dead Brushless DC motor into a powerful 3-phase energy generator.

The process is really simple and after going through this instructable, i am sure you will be able to do it for yourself.

The absence of brushes in them makes it unique when compared to other generators because its efficiency is much greater than the brushed ones that undergo losses because of the friction.

When a bldc Motor motor stops working.It is usually it's driving circuit that dies.

Intel i5-7xxx are quad core, but then they probably use too much power to be run fanless, so this is likely something new.
There are plenty of Intel boards with quad core on them, and if you open it up to all AliExpress, there must be thousands.
Anyway, quad core isn't THAT important until you want to run VirtualBox, then the cores and the RAM have to be shared out.

As far as those prebuilt Micros are concerned, what do you think would be adequate configuration? 

For doing what?

the i5/4010U.  How does that processor stack up overall IYHO?

No idea.

8 Gigs RAM/128 Gigs SSD.

If you've got that much data to store I'd be surprised.

Do these things come with Linux pre-installed?  What Linux?  If not, then you are going to have to learn how to install stuff.  That's not "pro" stuff.  Diagnosing problems and fixing software is pro stuff.

Forget I ever asked.  Your expertiese is not proving very helpful here.


Yup.  :coffee:

RE, Palloy's instructions for the Virtualbox running of Linux inside windows are okay but they lack something important. I researched all this a couple of years back and got reliable instructions from Ask Leo on how to do this. The problem is that defending Linux from hacking in general and malware in particular can be tricky. Norton does that, of course, but, at least according to Ask Leo, retail security software is NOT rock solid on Linux but is extremely reliable on Windows. Since I have (reluctantly) been forced into windows10 with my i3 new Dell Inspiron machine, I received the unexpected pleasant surprise of not being a target of the NSA malware recently being used to hack windows versions  :emthup: :icon_sunny:  (Palloy posted here on it recently - It's an article in the Intercept).

At any rate, security is NUMERO UNO for me. And I don't want to even try to keep up with the hackers out there. So, I pay Norton about $84 a year to do the heavy lifting while I continue to use CFS in dealing with e-mails and suspicious web sites. Norton has been good to me. They have saved my arse on several occasions over the last DECADE.  :emthup:

Linux has a lot of attraction for me but I never got around to that Virtualbox testing of it. Maybe someday.

When I had a total disk failure two computers ago, I was able to run Ubuntu from a CD to shop for a new computer with a dial up backup I still had. I no longer have dial up (I save $19.95 a month by not having it  :icon_mrgreen:) so that is no longer an option.

The last time my hard disk failed, I was STUCK without a computer to shop for a computer so I had to do it by phone (UGH!).  :P

Yeah, I should have a backup hard disk with an image of my operating system to avoid that, but I haven't gotten around to that yet. Hopefully, I'll get one this summer.

Hope this helps you, RE.  :icon_sunny: I'm certain Palloy will, of course, not be impressed AT ALL.  ::)

Well, I'm impressed with your commitment to security.   :emthup:

Norton (now Symantec) AntiVirus does run on Linux, but since they charge for it and it's not open source, Ubuntu doesn't make it available, and nobody would use it.  ClamAV is the recommended free and open source solution.  Symantec SAV has to be a complete re-write of the Windows version, because the arrangement of the file system on Linux is completely different from Windows (no C:\  at the top of the hierarchy of directories, no Registry, etc).  99% of all viruses are written to target Windows machines, and won't run at all on Linux. 

Even if someone were to write a virus specifically for Linux, and sneak the file into the file system somehow, it could only run under your user's account, and so would only have access to that part of the file system that you own - /home/palloy/  (being equivalent to C:\Users\palloy\ ).  So it could trash your files, but it couldn't trash other users' files, or the OS itself, which belongs to "root". 

And you DO have a backup of your files, don't you? - yes, of course I do, every day at 01:00 am.

Suffice to say that in 5 years of Linux, on what is now 5 machines, I have never even been warned about a virus, let alone been infected by one.   :icon_sunny:

6 machines if you count my Android smartphone, but I rarely switch it on, and NEVER let it talk to the other computers on the home network, because I don't trust Android and because the Android version is no longer supported.  :(

Ubuntu is owned by Canonical, who I suppose make their money by providing paid technical support.  However the Linux community experts provide free support at places like AskUbuntu, StackExchange, etc.

Well, I haven't gotten around to total image backups although I think that would be ideal. What I do, since I'm too cheap to get another hard disk or even a solid state USB disk on a stick to put a recovery thing on, I take my CDs and copy my NEW document and picture files, current screenshot of desktop with programs list, favorites list, names of latest program additions and new sketchup graphic files I've doodled in my spare time to it in compressed form once a month.

If the hard disk dies before I make my recovery thing, I'll just have to wing it.  :P

Having a tiny forum also provides me with a second backup to my pictures and screeds that won't perish with my hard disk. I do not trust the cloud and will never store zip on it. Yes, I know the gooberment, microsofty, my server and the NSA knows every keystroke I have ever made and has stored all my activity since I was born (on the internets), but they don't like to admit that.  :evil4:

So, I do what I can.   8)

Why Does Everyone Put Their Pots and Pans under the Stove?

You know that drawer underneath the oven, where you throw all the saucepan lids, cookie sheets, and muffin tins? Manufacturers say that it's actually a warming drawer, and you’re supposed to be using it to keep hot foods at serving temperature, especially when you’re making an elaborate meal for a lot of guests. Who knew? However, it’s important to know that this drawer isn’t designed for cooking food, just for keeping it warm after it comes out of the oven.

Kitchens of the past:

⦁   The first cast iron stove was invented in 1795 by Sir Benjamin Thompson, Count Rumford. It had a single fire source and the temperature could be regulated for several pots at the same time.

⦁   The first commercial gas stove, designed by James Sharp, hit the market in 1834. The gas stove was easier to regulate and required less upkeep than wood or coal stoves.

⦁   Electric stoves were first used in the 1890s, following the introduction of home electricity. The Amana Corporation, a subsidiary of Raytheon, introduced the first microwave in 1967, but the high price and the public's fear of radiation delayed its acceptance.

10 Unconventional Ways to Use Old Paper Towel and Toilet Paper Rolls Around the House

Libby Baker   
October 30, 2016  59 Comments  (numerous links in article at main link)

Toilet paper and paper towels: great household tools, but there just really aren’t many desirable eco-friendly substitutes in a green living household, besides outfitting your bathroom with a bidet. It helps to be conscious of your toilet and paper towel consumption, of course. And forgoing the lotioned, cushioned, perfumed brands for unbleached and recycled paper will help. But you can also minimize your contribution to the landfill by recycling the rolls from your toilet paper and paper towel rolls. Here are some great, unconventional ways to reduce and reuse:

1. Cord Holder

Don’t buy plastic contraptions to keep your cords from becoming tangled. Make your own ridiculously easy recycled cord holder with the cardboard tubes from toilet paper or paper towels. And you can fancy it up with wrapping paper — perfect for saving those tiny leftovers not quite big enough to wrap a gift.  Use this trick for keeping string lights from becoming a tangled mess!

2. Green Seedling Greenhouse

I love the idea of recycling products made from trees back into the garden. The diameter of a paper tube is the perfect size for sprouting seedlings! Why not make use of that leftover plastic produce container to make an ideal seedling greenhouse! You can just plant these Toilet Roll Seed Starter pots right into the ground. The cardboard will decompose as the plant grows.

3. Plant Protectors

Once those seedlings are growing strong in the garden, keep them safe from bugs and critters by making Plant Protectors. You can also place tubes around the base of young trees to keep them safe and provide support.

4. Bird Feeders

Don’t forget the critters who help with pest control in the garden! You can attract birds to your garden by keeping a source of food, like these awesome bird feeders made from toilet paper tubes, hanging on your trees during the lean winter months!

5. Napkin Rings

You may have already ditched the paper napkins for reusable cloth napkins, and now you can make them even prettier with these upcycled napkin rings made from leftover fabric scraps. Or, use up leftover yarn by wrapping the cardboard tube to make these cute napkin rings.

6. Art

You don’t have to spend a ton of money to redecorate your home! Get creative and make your own decor out of things you already have. Spruce up a boring old wall clock or make visually striking picture frames by adding scrolls made from recycled cardboard tubing, or make a faux iron gate to add interest to your walls. Better yet, make your own artwork by using foraged branches and cardboard tubes. Or just create cardboard tube art directly on the walls! How about a beautiful bouquet of cardboard thistles in a vase on your table? Let your imagination go wild!

7. Knitting

Got a knitting hobby and too many needles? Keep track of them all by storing them according to size in leftover cardboard tubes. Spool skeins into balls around tubes to keep yarn from getting tangled. You can even use the tubes and some popsicle sticks to make your own Spool Knitter!

8. Gift Boxes

Never buy fancy gift boxes again! Make your own with this easy Cardboard Tube Pillow Box tutorial.

9. Tabletop Goodies

Protect your table tops by making beautiful and delicately scrolled drink coasters.  Or just cover the whole tabletop with this table runner.

10. Eyeglass Case

Cardboard tubing is the perfect size for one of the most important accessories for those of us who wear glasses: eyeglass case! Make your own fabric covered eyeglass case with this no-sew tutorial!

What ideas do you have for ways to reuse these little cardboard tubes?

How to do a Western Union Splice

by deluges

This is the solder splice that offers the least resistance I've ever found : less than a hundred micro ohms!  :o    My Ohmmeter doesn't read less than that, so I'm happy with it.  :D

It's quite easy to do and offers great mechanical resistance for virtually no electrical resistance. :)

First you want to remove a good 5 cm (2 inches) of insulant on the wires, then twist them on themselves to make a single thick brand.

There's a great scheme here that came from wikipedia and sums up the following:

1) Fold in the middle and give one or two turns

2) Wrap tightly around the other wire using pliers or your fingers if you feel strong today

Quote from a friend in Australia who wishes to remain anonymous and my reply: 

Hello agb

I want to discuss this with you since i know u have open mind to and researched such phenomena. I will tell in detail and later try and take fotos and measure distances to be more precise.  Yesterday was Sunday,  Myself and Junior had spent the day working on a 63 EJ Holden (a medium size   local GM car)  in my garage.

The water  pump that takes water from the main tanks to the header tank up high for gravity water pressure hasnt been working and I havent had it fixed because if i take the pump out i will have no water, because  i have the water  still running through the pump into the house pipes. I plan to get an electric pump instead,  jyst been too busy to sort it out. I have enough water running out of taps,  but not with enough pressure to have a shower. For that reason,  after working on the car all day,  we went down into town to use the coin operated shower at the park which is a public RV campground. I took the dog also because lately i have not been well since that moron caused me to swallow petrol and i dont feel energy to ealk the dog, so I decided to tie the dog to the side of the pickup to let him run for a mile as he spends the day on a chain fixed to a long cable it moves along,  he likes more exercise.

So it was roughly 8.30pm when we were heading home and i was tying the dog to the side of the pickup to run the last mile to home. when i did that i noticed a whitish light over a hill,  i thought there must be someone in a 4wd back there with powerful headlights and spotlights. I got in the truck and said for a joke 'theres a ufo over there' .

Let me explain the geography/topography. there is a river valley with a highway and rarely used train line for coal running more or less along the river. The elevation at the town,  flat level is 250m according to the altimeter in the truck. There are mountains on either side. See if u like Ben Lomond rangeon the north side at 1000m and Douglas Apsley range on the south side of Esk river at maybe 600m. But before the mountain ridge there are smaller hills that extend out into the valley If u know what i mean. So as i was beginning to head uphill but on a gradual slope for about half a mile I have a hill on my left at 350 m elevation and a bigger hill on my right that is bigger and longer and at least 400m elevation. I can see that the land is cleared at up to about 350m on that hill but on the other side where the light came from it could be cleared further in. The light was not behind the lower cleared section but the higher part that would be 400 to 450m,  the side i was looking at that is not cleared is steep,  but on the other side if it is more flat it is probably cleared. I am labouring this point because a ufo would need a clear field to land but could only hover over a forest.

So of course junior wanted to see and looked although he was on the wrong side to see as well as me, as we looked at the light it got weird. That was no vehicle or shooters with spotlights. There were beams of light in an angle upward,  but not straight up vertical, neither 45o but more upright than that. The beams were rotating around but glowing variably in brightness and speed. There were no different colours only white. The best description is like a crown.

I wanted to stop and watch but there were too many sheep and cows around and the dog would have started barking at them if i stopped. I jnew that further up i could get a good look at the same place from higher though not as high as the hill the lights were behind, but further away and there were no livestock there,  so i did that. At first i couldnt see anything then it went again  , lit up bright like a crown, and junior insisted i go back to the truck even though i wanted to keep watching.

So i went home and dumped the dog and headed quickly back down,  this time as close as possible to the nearest fence and field. For a while i saw nothing except one single beam of light only for a second,  then there was a light moving in that field and i thought at first it was a person out there with a spotlight from the nearest farmhouse because we were there. Then the light was in the field on the opposite  side and it moved very quicklythrough that  field. Because i was now on the wtong side to see it well ,  i didnt see but junior did,  and he said it moved away very fast in the same direction dissapeared.

This light that was not over the hill is more puzzling. If it was a spotlight from the farmhouse checking who is out there,  why did it never shine at us?  If it was a light from the house that was checking the field on the left and then on the right it should have crossed us where we were,  unless somebody checked one field then turned it off and then checked the other field. But i need to experiment myself tonight to see if i can replicate what it looked like from the same distance. The reason is that this light moving quickly in one field then the other was not really long with an obvious starting point,  like a long cone of light. Instead it was more like a length of light about 40m long and taoering down at either end,  never staying in one spit long enough to see properly.

After that we waited another 20 minutes and saw nothing more.

Well, it looks like UFO activity, all right. The lack of noise is always an indicator that no military activity is producing  the lights. Light diffuses rapidly from the distance of the source. The beams you were seeing could not have been coming from far away. So something THERE was producing them without noise. The only thing remotely similar is one of those rock concerts that make light shows that look somewhat like a crown of lights at varying angles above 45 degrees from a distance. And that was OBVIOUSLY not the case here.

As to why the search light you mentioned didn't pass over you, maybe it was just trying to track the light beams and ignoring anything else out there.

I have read about some very strange light phenomena before earthquakes, but since your dog was not agitated that possibility must be ruled out as well.

I would say you had a close encounter. And when one happens, it usually means there will be more for a few months. Keep your camera ready. Maybe you can get some good film of one of the vehicles that is the source of those lights.

I read with interest about your water pumping issues. I had some problems with flooding a few years back and came up with an invention (that I never actually manufactured because my wife went out and bought an electric pump) that is a very robust type of peristaltic pump mechanism. Since you are handy with machinery, you might want to have one of these around. If your water pressure is too low, you can use this mechanism with a hose to your shower head or your main tank in times of need.

Unlike a normal peristaltic pump, there really isn't anything on it that wears out except the hose that is being squeezed by it and the small electric motor from a drill that powers it.

The sprockets used are very tiny. They are the smallest ones on a three speed bicycle next to the rear wheel.

Here's the design. I'm sure you could improve on it to make it simpler and cheaper:

It would make a nice back up and you could possibly run it manually with a bicycle instead of an electric motor.

Ultimate Night Vision Headlamp - 500+ lumens with only 8 watts

by MonkeyLectric

The 507nm LED Night Vision Special!

Headlamp flashlight technology takes a quantum leap!
You can have it all: * Intense brightness * Lightweight * Long life * Low cost * Rechargeable * Unbreakable * Small * Waterproof * Unique shocking turquoise color

Race proven! I put the light to the ultimate test by competing in the Gold Rush 24-hour Adventure endurance race in the Sierra Nevada mountains of California. Many of the other competitors had $500 HID lamps from NiteRider, Light & Motion, etc, yet throughout the race nearly everyone that saw my light commented as to its extreme brightness or asked where they could get one. It was that much brighter than anything else.

 brightness: 500+ lumens / 7 million+ mcd @ 15 degree
 weight: 120 gram headlamp + 60 gram electronics + 280 gram battery pack = 460 gram total
 cost: $60 including batteries
 lifetime: 3, 6, 12, 24 hours (4 brightness settings)
 size: headlamp portion 5cm x 5cm x 2.5cm
 rechargeable: Ni-MH or Lithium-Ion batteries (your choice)
 unbreakable: LED technology

 - Cyan (or Green) high power/high efficiency LED's
 - high-transmittance TIR lenses
 - high-efficiency DC/DC step-down converter

 None of this was possible just a couple years ago, but now it can be done easily with inexpensive components you assemble yourself!  ;D

 i've got several other power-LED instructables too, check those out for other notes & ideas.

This article is brought to you by MonkeyLectric and the Monkey Light bike ilght.

Step 1: What's so special here?

Your eye! Remember back to biology class - your eye has "rods" and "cones". these are the sensing cells in your eye that detect images. the cones are your daylight & color vision, but they are less sensitive than the rods. Now the part you didn't learn in school:

(1) The rods are about 2.5 times more sensitive to light than the cones. That's why they are your night vision.

(2) The rods and the cones are not equally sensitive to all colors (wavelengths) of light. The wavelength of maximum sensitivity for your rods is 507nm, or blue-green. Why? Moonlight is more bluish than sunlight. The color of maximum sensitivity for your cones is 555nm green, about the color of plants. (more info)

To get the best possible vision at night, we'd like to build a lamp that puts out the most light at the 507nm that our rods are most sensitive to. This gets us the best vision at night for the least power used. If we had a white light instead, it would take much more power to get as much visibility.

Thanks to our friend the LED, this weird pure turquose light is possible! The latest LED technology is much more efficient than a standard light bulb to begin with, but using the special turquose color gives us even much better night vision than white, and is more efficient than even the fanciest HID lights.

$10 Smartphone to digital microscope conversion!
 by Yoshinok

The world is an interesting place, but it's fascinating up close.  Through the lens of a microscope you can find details that you would otherwise never notice.  But now you can.

This instructable will show you how to build a stand for about $10 that will transform your smartphone into a powerful digital microscope. This DIY conversion stand is more than capable of functioning in an actual laboratory setting. With magnification levels as high as 175x 375x Edit: with the addition of a second lens magnification can be as high as 375x, plant cells and their nuclei are easily observed! 

In addition to allowing the observation of cells, this setup also produces stunning macro photography.

The photos in this instructable were taken with an iPhone 4S.  Watch the video below for a quick overview of the project! 


The cost of this project is just $10 (not counting the smartphone), and it only takes about 20 minutes to build. You can be viewing cells with your smartphone within the hour!

Materials required:
 3x 4 ½” x 5/16” carriage bolts
 9x 5/16” nuts
 3x 5/16” wing nuts
 5x 5/16” washers
 ¾” x 7” x 7” plywood  -- for the base

Unusual uses for rice by jessyratfink  ;D


Rice is one of my all time favorite foods. I eat it with everything. If I can find an excuse to add rice to something I will. :D

But did you know that you can also use rice for all sorts of things around the house, too? Keep on reading to find out a few of my favorite unusual uses for rice.

Most of these unusual uses work best with plain white rice, but some can work with other varieties too. Though I suggest white rice since it's so cheap!

1: Save wet electronics

Probably one of the most classic uses for rice! If you've ever dropped your phone in water you're probably tried this trick. ;D

If you can turn the item off, do so. Dry the exterior of the item as best you can. If you can open it up and dry out the inside, that's a great idea too! For phones it's best to remove the battery and SIM card, too.

Place it in a ziploc bag or a container of rice and leave it for 24+ hours.

2: DIY heating pads

Another one of my favorite uses! Perfect for sprains and cramps and or even just a really chilly day. I always mess my neck up with too much computer work and embroidery, so I've made a long skinny one to go around the back of my neck. :)

You can either sew up your own heating pad or make one by filling a sock with rice. Then just pop in it the microwave for 30 seconds to a minute and enjoy!

3: Keep hand tools from rusting

This is really useful in humid areas! Back home in Kentucky this is done all the time - I've seen it in almost every workshop I've been in. If you have older hand tools that are susceptible to rusting, place them in a can of rice. (Sawdust can work too!)

This works especially well for pliers, screwdrivers and hammers.  ;D

It also keeps your tools within easy reach. Fancy.

4: Check to see if your oil is hot enough before frying

If you've ever been unsure about the temperature of your oil but you don't have a thermometer handy, rice is a good indicator. If you drop a couple grains of rice into your oil and they sink, it's not hot enough.

If the grains of rice pop back up immediately and begins to bubble, the oil is hot enough - normally around 350-360 F.

I say a couple because not all grains of rice will pop and float!

When I was doing this I just threw a ton of rice in there - puffed rice is delicious. DELICIOUS. So maybe just do that instead of frying something else.   ;) :D

5: Clean your coffee or spice grinder

One of my favorite uses! I think rice works much better than bread.

6: Clean containers with small openings

If you don't have a bottle brush around, rice is a great substitute.

Add a small amount of rice (perhaps a tablespoon?) into the container with a couple drops of soap. Add in some hot water and swish the rice around.

I clean my teapot like this all the time! I just put my thumb over the spout and hold the lid on while swishing the rice around.  ;D

7: Weight for blind baking

Blind baking is probably the way I use rice the most often. (Well, besides stuffing my face. I love rice.)

Both rice and beans and great blind baking weights.

To blind bake pastry, form the pastry in the tart or pie pan and then place a piece of parchment over the pastry. Pour in enough rice so that the pastry is completely filled.

Bake the pastry for half the required time and then take it out to check. If the pastry has gone lightly golden brown around the edges (like the photo above), you'll know it has set and won't go sliding down the side of the pan.

Use the parchment to transfer the rice from the crust into a container for later use. Once you've "baked" the rice, you can't use it to cook later, so I keep mine in a gallon mason jar separate from my eating rice.  ;D

Place the crust back in the oven to finish baking, and viola - perfectly blind baked pastry!

8: Makeshift knife rack
  Agelbert NOTE: Since bacteria sort of like rice A LOT (I learned at a young age that you can keep thousands of paramecium happy with a single grain of rice!), I don't recommend this procedure unless you live in Antarctica (low humidity + seriously low temperatures).

I can't say how well this works as a permanent knife rack - but it's fantastic if you're just setting up your kitchen or if you just moved and find yourself without one.

Find a tall wide mouth container and pour in enough rice so the blades will be mostly covered.

The one caveat here is to be careful when putting the knives into the rice - there's not much to stop them colliding with the bottom of the container - so you can dull the tips if you're not careful.

Looks pretty awesome, too.

9: Slow release air freshener

This is perfect for closets or bathrooms - any small space where you want a little fragrance! This air freshener isn't strong enough for any large rooms, though. Tried it in the bedroom and it wasn't noticeable, but in a small bathroom it is.

Find a small glass container to put the rice in - I normally use between 1/4 and 1/2 cup. Add 10-20 drops of essential oils and mix well.

Place it where you want for a subtle and long lasting air freshener - just shake the container whenever you feel the smell is dying down - that will refresh it. :D

Just be careful to put these air fresheners high - out of small hands and away from pets!

When you run out of these:

, you can get your brother good with some rice pellet replacements!   

Mandatory safety precaution:
Make sure you kids that try shooting each other with rice have glasses on, okay?

Build a High Performance FPV Camera Quadcopter
by Toglefritz

Far out!

This Instructable will show you, in detail, how to build a high-quality quadcopter for flying FPV and recording aerial photos/videos.

We all know humans can't fly. Our bones are far too dense and flapping our arms does not produce adequate lift to overcome the pull of gravity, but luckily we can use technology to give us the experience of flying. I'm not talking about flying in airplanes though, or a hang glider, or jumping out of airplanes, or using a zip line. We can actually use multirotor aircraft to give us the impression of flying using a technology called FPV. I think "flying" with an FPV-equipped multirotor is even better than flying with any of the aforementioned technologies though because multirotors are infinitely more agile. Flying with FPV is more like being a bird and less like being thrown through the air. It is an amazing, and very fun, technology.

This Instructable will show you how to build what I would categorize as a high-performance FPV quadcopter that can be used to take amazing aerial photos and videos. We will be using a top-of-the-line flight controller (the DJI Naza M Lite) and an excellent FPV system from Fat Shark, with the PilotHD camera for both recording video and delivering the FPV feed. We will also be using high quality motors and ESCs designed specifically for use in multirotors. Finally, we will be using a premium-quality Spektrum radio system. More about the parts list for this project can be found in the next step.

Super Basic Solar Lighting under $75

by lumpytrout

About: We are designer/builders making cool stuff and cozy mod cabins from recycled materials. We have a bunch of projects coming up so please follow us if you would like to see more recycled and energy efficient projects!

Location: Pacific North West

Joined: Apr 24, 2014


If you are looking for a simple, inexpensive but durable solar lighting setup for your shed or outbuilding then this tutorial is perfect for you. There are many tutorials on this site but we wanted to make our system as frugally as we could and still have a quality setup that would serve most people's basic lighting needs. Our total budget for this whole project was about $75 USD and I hope to get many years of maintenance free use from this system. I set up three lights because I love good lighting but this could easily be cut down to just two (interior and exterior) and would work great.

Making good

Repairing things is about more than thrift. It is about creating something bold and original


Philip Ball is a British science writer, whose work appears in Nature,New Scientist andProspect, among others. His latest book isInvisible: The Dangerous Allure of the Unseen(2014).

The 16th-century Japanese tea master Sen no Rikyū is said to have ignored his host’s fine Song Dynasty Chinese tea jar until the owner smashed it in despair at his indifference. After the shards had been painstakingly reassembled by the man’s friends, Rikyū declared: ‘Now, the piece is magnificent.’ So it went in old Japan: when a treasured bowl fell to the floor, one didn't just sigh and reach for the glue. The old item was gone, but its fracture created the opportunity to make a new one.

Smashed ceramics would be stuck back together with a strong adhesive made from lacquer and rice glue, the web of cracks emphasised with coloured lacquer. Sometimes the coating was mixed or sprinkled with powdered silver or gold and polished with silk so that the joins gleamed; a bowl or container repaired in this way would typically be valued more highly than the original. According to Christy Bartlett, a contemporary tea master based in San Francisco, it is this ‘gap between the vanity of pristine appearance and the fractured manifestation of mortal fate which deepens its appeal’. The mended object is special precisely because it was worth mending. The repair, like that of an old teddy bear, is a testament to the affection in which the object is held.

A similar principle was at work in the boro garments of the Japanese peasant and artisan classes, stitched together from scraps of cloth at a time when nothing went to waste. In boro clothing, the mends become the object. Some garments, like the fabled ship of Theseus, might eventually be overwhelmed by patches; others were assembled from scraps at the outset. In today’s trendy Tokyo markets, the technique risks becoming a mere ethnic pose. But boro was always an aesthetic idea as much as an imposition of hardship.

Although quite different in their social status, boro and the aesthetic of repaired ceramics alike draw on the Japanese tradition of wabi-sabi, a world view that acknowledges transience and imperfection. To mend a pot, one must accept whatever its fracture brings: one must aspire tomushin — literally ‘no mind’ — a state of detachment sought by both artists and warriors. As Bartlett explains in her essay ‘A Tearoom View of Mended Ceramics’ (2008): ‘Accidental fractures set in motion acts of repair that accept given circumstances and work within them to lead to an ultimately more profound appearance.’

Mended ceramics displayed their history — the pattern of fracture disclosing the specific forces and events that caused it. Indeed, earlier this year, a team of French physicists from the Aix-Marseille University demonstrated that the starlike cracks in broken glass plates capture a forensic record of the mechanics of the impact. By reassembling the pieces, that moment is preserved. The stories of how mended Japanese ceramics had been broken in the first place — like that of the jar initially spurned by Rikyū — would be perpetuated by constant retelling. In the tea ceremony these histories of the utensils provide raw materials for the stylised conversational puzzles that the host sets his guests.

For years, I have been patching clothes into a kind of makeshift, barely competent boro. Trousers in particular get colonised by patches that start at the knees and at the holes poked by keys around my pockets, spreading steadily across thighs with increasing disregard for colour matching. Only when patches need patches does the recycling bin beckon. At first I did this as a hangover from student privation. Later it became a token of ecological sensibility. Those changing motives carried implications for my appearance: the more defiantly visible the mend, the less it risks looking like mere penny-pinching. That’s a foolishly self-conscious consideration, of course, which is why the Japanese aesthetic of repair is potentially so liberating: there is nothing defensive about it.

This feels like rather a new idea in the pragmatic West. But things might be changing. Take, for example, the all-purpose mending putty called Sugru, an adhesive silicone polymer that you can hand-mould to shape and then leave overnight to set into a tough, flexible seal. As its website demonstrates, you can use Sugru for all those domestic repairs that are otherwise all but impossible, from **** toilet seats to split shoes or the abraded insulation on your MacBook mains lead. (Doesn’t it always split where it enters the power brick? And isn’t it exorbitantly costly to replace?) Sugru was devised by Jane Ní Dhulchaointigh, an Irish design graduate at the Royal College of Art in London, working with a group of retired industrial chemists. Timemagazine pronounced it a top invention of 2010, and it has since acquired an avid following of ‘hackers’ who relish its potential not just to repair off-the-shelf products, but also to modify them.

It wasn’t so much that things stopped working and then got repaired, but that repair was the means by which they worked at all

Sugru doesn’t do its job subtly, which is the point. You can get it in modest white, but fans tend to prefer the bright primary colours, giving their repairs maximal visibility. They present mending not as an unfortunate necessity to be carried out as quietly as possible but as an act worth celebrating.

A similar attitude is found in the burgeoning world of ‘radical knitting’. Take the textiles artist Celia Pym, who darns people’s clothes as a way of ‘briefly making contact with strangers’. There are no ‘invisible mends’ here: Pym introduces bold new colours and patterns, transforming rather than merely repairing the garments. What Pym and the Sugru crew are asserting is that mending has an aesthetic as well as a practical function. They say that if you’re going to mend, you might as well do it openly and beautifully.

Their approaches also reflect another of the aesthetic considerations of Japanese ceramic repairs: the notion of asobi, a kind of playful creativity introduced by the 16th-century tea master Furuta Oribe. Repairs that embody this principle tended to be more extrovert, even crude in their lively energy. When larger areas of damage had to be patched using pieces from a different broken object, one might plug the gap using fragments that have a totally different appearance, just as clothes today might be patched with exuberant contrasting colours or patterns. Of course, one can now buy new clothes patched this way — a mannered gesture, perhaps, but one anticipated in the way that Oribe would sometimes deliberately damage utensils so that they were not ‘too perfect’. This was less a Zen-like expression of impermanence than an exuberant relish of variety.

Such modern fashion statements aside, repair in the West has tended to be more a matter of grumbling and making do. But occasionally the aesthetic questions have been impossible to avoid. When the painting of an Old Master starts cracking and flaking off, what is the best way to make it good? Should we reverently pick up the flakes of paint and surreptitiously glue them back on again? Is it honest to display a Raphael held together with PVA glue? When Renaissance paint fades or discolours, should we touch it up to retain at least a semblance of what the artist intended, or surrender to wabi-sabi? It’s safe to assume that no conservator would ever have countenanced the ‘repair’ last year of the crumbling 19th-century fresco of Jesus in Zaragoza — Ecco Homo by Elías García Martínez — by an elderly churchgoer with the artistic skills of Mr Bean. But does even a skilled ‘retouching’ risk much the same hubris?

These questions are difficult because aesthetic considerations pull against concerns about authenticity. Who wants to look at a fresco if only half of it is still on the wall? Victorian conservators were rather cavalier in their solutions, often deciding it was better to have a retouched Old Master than none at all. In an age that would happily render Titian’s tones more ‘acceptable’ with muddy brown varnish, that was hardly surprising. But today’s conservators mostly recoil at the idea of painting over damage in old works, although they will permit some delicate ‘inpainting’ that fills cracks without covering any of the original paint. Cosimo Tura’s Allegorical Figure (c. 1455) in the National Gallery in London was repaired this way in the 1980s. Where damage is extensive, it is now common to apply treatments that prevent further decay but leave the existing damage visible.

Such rarefied instances aside, the prejudice against repair as an embarrassing sign of poverty or thrift is surely a product of the age of consumerism. Mending clothes was once routine for every stratum of society. British aristocrats were unabashed at their elbow patches — in truth more prevention than cure, since they protected shooting jackets from wear caused by the shotgun butt. Everything got mended, and mending was a trade.

What sort of trade? Highly skilled, perhaps, but manual, consigning it to a low status in a culture that has always been shaped by the ancient Greek preference for thinking over doing (this is one way in which the West differs from the East). Over the course of the 19th century, the ‘pure’ theorist gained ascendancy over the ‘applied’ scientist (or worse still, the engineer); likewise, the professional engineer could at least pull rank on the maintenance man: he was a creator and innovator, not a chap with oily rag and tools. ‘Although central to our relationship with things,’ writes the historian of technology David Edgerton, ‘maintenance and repair are matters we would rather not think about.’ Indeed, they are increasingly matters we’d rather not even do.

Edgerton explains that, until the mid-20th century, repair was a permanent state of affairs, especially for expensive items such as vehicles, which ‘lived in constant interaction with a workshop’. It wasn’t so much that things stopped working and then got repaired, but that repair was the means by which they worked at all. Repair might even spawn primary manufacturing industries: many early Japanese bicycles were assembled from the spare parts manufactured to fix foreign (mostly British) models.

It’s not hard to understand a certain wariness about repair: what broke once might break again, after all. But its neglect in recent times surely owes something to an underdeveloped repair aesthetic. Our insistence on perfect appearances, on the constant illusion of newness, applies even to our own bodies: surgical repairs are supposed to make our own wear and tear invisible, though they rarely do.

Equally detrimental to a culture of mending is the ever more hermetic nature of technology. DIY fixes become impossible either physically (the unit, like your MacBook lead, is sealed) or technically (you wouldn’t know where to start). Either way, the warranty is void the moment you start tinkering. Add that to a climate in which you pay for the service or accessories rather than for the item — inks are pricier than printers, mobile phones are free when you subscribe to a network — and repair lacks feasibility, infrastructure or economic motivation. Breakers’ yards, which used to seem like places of wonder, have all but vanished; car repair has become both unfashionable and impractical. I gave up repairing computer peripherals years ago when the only person I could find to fix a printer was a crook who lacked the skills for the job but charged me the price of a new one anyway.

Some feel this is going to change — whether because of austerity or increasing ecological concerns about waste and consumption. Martin Conreen, a design lecturer at Goldsmiths College in London, believes that TV cookery programmes will soon be replaced by ‘how to’ DIY shows, in which repair would surely feature heavily. The hacker culture is nurturing an underground movement of making and modifying that is merging with the crowdsourcing of fixes and bodges — for example, on websites such as ifixit.com, which offers free service manuals and advice for technical devices such as computers, cameras, vehicles and domestic appliances. Alternatively there is fixperts.org, set up by the design lecturer Daniel Charny and Sugru’s co-founder, James Carrigan, which documents fixes on film.

The mending mindset has taken to the streets in the international Repair Café movement, where you can get free tools, materials, advice and assistance for mending anything from phones to jumpers. As 3D printers — which can produce one-off objects from cured resin, built up from granular ‘inks’, layer by layer — become more accessible, it might become possible to make your own spare parts rather than having to source them, often at some cost, from suppliers (only to discover your model is obsolete). And as fixing becomes cool, there’s good reason to hope it will acquire an aesthetic that owes less to a ‘make do and mend’ mentality of soldiering on, and more to mushinand asobi.

Building the earthship way 

 If you're thinking about building a house, shed or other building, consider using a tire wall!

 It's a great way to upcycle old beat up tires and keep them from going to the landfill.

 In addition, they're super sturdy, effective and make for excellent insulation.

 This video will explain exactly how the process works.
