The flame sensor is a module that detects the infrared (IR) radiation that comes from a fire 🔥, the Sun , and other sources of heat.

Thanks to controller boards such as Arduino, sensors are easy to use and affordable , which makes them very attractive as an educational resource. This lnstructable aims to bring teachers closer to the didactic use of low-cost sensors in the Physics class. We will offer examples of practical activities in which sensors are used as a tool to illustrate physical concepts, to show the relationship between magnitudes in a practical way, or to take measurements in laboratory activities.

This project will show you how you can make a simple compass with duct tape, a cork, a needle and a magnet: a floating needle compass.

The benefit of this duct tape design is that the this compass can be rolled and stored neatly when not in use, a duct tape collapsible compass; how cool is that?

Is Duct Tape Actually Used for Sealing Air Ducts?

William Shakespeare's Juliet famously asked, "What's in a name?" to argue that it doesn't matter what you call something: It is what it is. But Juliet never had to repair air-conditioning vents. If she had, she might have learned what a scientific study found out over 20 years ago: Duct tape doesn't work on ducts.

In fact, according to the results of the testing done at Lawrence Berkeley National Laboratory, of the 33 types of sealants tested on the leaky joints on a wall of joined ducts, duct tape was the only one that "failed reliably and often quite catastrophically." ;D

The study included numerous varieties of duct tape, as well as materials such as injected aerosol sealants and plain old clear tape. Although duct tape came in last for sealing leaking ducts, it remains a popular tool for a huge range of other uses, from sealing bags and removing lint to killing warts and constructing your own wallet. :D

The tale of the duct tape:

► Duct tape was developed by Johnson & Johnson as a way to better seal ammunition packages and repair equipment during World War II.

► Duct tape is sometimes called "duck tape" because of its ability to repel moisture, just like the feathers on a 🦆 duck's back.

► The amount of duct tape sold every year could stretch beyond the 🌚 moon or wrap around the 🌎 Earth more than a dozen times.

DIY Microwave Kiln | Fuse Glass in Your Microwave

By ShakeTheFuture in Metalworking


In this Instructable, we'll look into way to make a microwave kiln.

For those who don't know what is a microwave kiln, here is a quick introduction.

Microwave kiln is a kiln that you can put in your regular microwave oven.

It does not use a wire heating element or gas to heat up. Microwave kiln is covered with silicon carbide.

Silicon carbide absorbs microwaves and turns them into heat.

Microwave kilns are usually used to fuse glass.

You can turn broken glass into amazing jewelry.

There is so much more that you can do with microwave kilns.

I use a microwave kiln to burn out Wax or Pla from plaster molds. It works very good.

You can also melt metals, but more on that in another Instructable, since there is much better way to do it by using the same principle.


► Sodium Silicate
► Silicon Carbide
► Ceramic Fiber Blanket/Kaowool
► Scale
► Mist Spray Bottle
► Sugru
► Blow torch
► Plaster of Paris or Any other Plaster

Step 1: Making a Plaster Ring

Can we blow off these PEX fittings? Sharkbite vs Viega vs Uponor

Matt Risinger
Published on 🎄 Dec 25, 2018

I was wondering the other day how much pressure a PEX fitting might withstand before it pops off, so I had Jordan make me a test rig!  In this video we are testing Sharkbite Push To Connect fittings, Viega fittings, Uponor fittings, and two types of crimped Sharkbite PEX fittings with a rig that goes up to 14,000 psi!  The results sure surprised us.  Enjoy this special Christmas edition of The Build Show!

Agelbert NOTE: I believe my home water lines are PEX A. I just want to say they are GREAT pipes 👍. My pipes froze one January here in Vermont and they did not burst or leak after they were thawed by a service that did the job the next day. That was over 4 years ago. We still have no leaks. My Manufactured Home is now 19 years old. 8) I have crimp fittings but if I ever have to raplace or modify my pipes, I will use Sharkbite fittings because they are HUGE time savers.

My science teacher daughter loves pulleys and has a whole demo set-up she put together for her students. I'll have to share this one wit her. Awesome.

It would have gone a lot faster if he just used some dynamite.   ;D


Glad you liked it, Eddie. 

RE, always wanting to do things FASTER is what got us into the mess we are in totday. And dynamite harms the soil. Using pulleys is the most environmentally sustainable way to engage in brute force actions like uprooting a tree.

It was a JOKE AG.  ::)

You will note though he is still using an FF powered winch to yank the ropes.  You can hear it in the background.


Okay. ;D  Yeah, I noticed that about the winch.  ;) But an electrical winch would have done the job just as well.

You couldn't set up an electric winch there, at least not straight solar.  Too many trees around, not enough sunlight hitting the ground to power the winch.  Similarly, not enough wind to power wind turbines when there are so many trees blocking the wind.

If you have a big enough portable battery bank you might do it, but that would be outrageously expensive, along the lines of the systems that DB sells and sets up.  This is out of the range of most people, you and me included there.

Dynamite comes cheap, and it really doesn't damage soil all that much.  It actually blows a lot of nitrogen into the soil.


I didn't say a thing about a solar powered winch. All tow trucks use an electric winch. Yeah, the source of energy ends up coming from fossil fuels, but the point is that electric motors, because of their instant and high torque performance, are the best type of motor for a winch. In fact, nearly all pulley applications (e.g. elevators) in modern society are applied with electric motors. Yeah some of the big cranes are fossil fuel powered but that is changing. Electric motors are better for use with pulleys. I had a friend who was an electrician on an oil platform in the ocean. They use LOTS of electric motors on those platforms because internal combustion engines have a bad habit of destroying clutches when used to lift heavy objects. Electric motors do not burn clutches simply because they do not need clutches.

The nitrogen compound that dynamite puts into the soil is not the same as the same as that contained in chemical fertilizers. If you want to believe the soil microbiota "benefits" from an explosion, then I will have to disagree with you. Killing thousands to millions of microbes in a blast won't improve their appetite for fixing nitrogen so plant life can benefit from access to nitrogen.

All that said, since this guy just wanted to pour a concret slab where the tree used to be, he certainly could have used dynamite. The concrete slab is the end for that area of usable soil.

This is part 2 of my project to remove a back leaning tree. This tree needed to be removed in this manner. I am pouring a cement slab right where this tree was. Using a chain saw or even digging it out would not have completely removed the roots. Not removing the roots (over time) would decay and cause the ground to sink.

Our Geodesic Dome Connector - How it Works! 💫

Zip Tie Domes

Published on Dec 25, 2017

https://www.ZipTieDomes.com - This video is about the design and fabrication of the Zip Tie Dome Geodesic Dome Connector / Geodesic Dome Hub.  This Geodesic Dome Connector is very easy to use and allows the construction of a Geodesic Dome without the use of tools and in a minimal amount of time.  The video describes the patented locking collar that surrounds the Geodesic Dome Hub, and how this outer collar controls the axial angles of the struts to create a much stronger geodesic dome than other types of Geodesic Dome Connectors. The video also describes how this is the only geodesic dome connector that can handle struts made out of non-standard size struts, such as metal rebar for concrete domes, or geodesic dome struts made from wooden dowels. This geodesic domes connector also works for building domes made from bamboo and other non-standard size struts.  🌟

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 ďShou Sugi BanĒ 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 youíre supposed to be using it to keep hot foods at serving temperature, especially when youíre making an elaborate meal for a lot of guests. Who knew? However, itís important to know that this drawer isnít 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 arenít 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

Donít 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 ó 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

Donít 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 donít 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 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

Technological disobedience 
The benefits of isolation

 Besides, there are English subtitles.  ;D

Cuba has been cut off from the corporate world for many decades.

In the process, it's created countless "unauthorized" technical workarounds that solve all kinds of problems.
