The project is about a home security system in which a cell phone is used as a device that will alert the owner of the house when an intruder enters the house. About the Instructable The owner just have to turn on the system before leaving his house.When an intruder enters the house in the absen...
Hello, we are a team of 3 Product Design Engineering students at the Glasgow School of Art. For a second year project called "Hydro Do That?" we were tasked with pumping 5 litres of water up a height of 60cm in the most efficient manner possible. The pump had to be capable of performing this task i...
This instructable is for those who ever wanted to build your own arduino or you just wanted to have another one or maybe a smaller one. Well I need this for a display project which had to keep the arduino running and I didn't want to let go of my original arduino.Making an arduino is actually easier...

When a Lexmark inkjet printer stopped working, [Mojobobo] was able to claim it as his own. He quickly realized that the machine was flooded with ink and not worth repairing, but that didn’t mean he couldn’t still find a use for it. When he learned that the printer’s firmware was not only upgradable but also unprotected, he knew he should be able to get the printer to do his own bidding.
[Mojobobo] started his journey with the motherboard. The unit still powered up, but it was asking to insert a “duplex module” before it would boot any further. [Mojobobo] … Read the rest
Over 1.5 billion people in the world have no access to electricity. That means 1 out of 5 people are forced to live without something that a majority of the world takes for granted everyday! Without electricity, these people are unable to refrigerate food/medicine, have a guaranteed light source, or...
This is an amazing induction heater and now you can build your own for fun or as a powerful tool. I have put together an extensive tutorial at http://ift.tt/1hyjjqy with schematics for building a 3 and 12kw unit. You'll be able to instantly melt steel aluminum and copper. You can use...
Power supplies are essential for at home tinkering and electronics hacking. Unfortunately, they’re really quite expensive, and a bit out of reach for most hobbyists. Computer ATX power supplies are a cheap alternative, although they usually tend to lack the features of real bench power supplies… unless you hack yours like [Mark Schoonover]!
When [Mark] set out on this project he wanted to use as many recycled components as possible, but still come up with an extremely functional bench top power supply. He snagged a 500W ATX power supply from one of his kid’s old desktop PC’s, grabbed some old … Read the rest
This is for the March 2014 Voltaic Build Night (Virtuabotix's first Build Night). We conducted this build at the Virtuabotix, LLC shop in Colorado. So the idea was to build a Voltaic Solar Panel, that could power and host an emergency communications network. This wasn't accomplished with the t...
Did you know that you can produce electricity by just walking? Here's a little science experiment that will show you a little secret on making insoles that can charge USB devices! The challenge is to make a slip-on insole that can produce enough electricity to charge batteries/ USB devices. Google...
Always when searching and gathering materials for all kind of projects I come across light bulbs, so probably many of you will also cross roads with a light bulb once in a while. Since light bulbs tend to die after a while, it's the perfect upcycle material. This collection brings together the most ...
This is a filament deposition delta 3D printer, was designed and built in 2013 using recycled parts from old dot matrix printers and flatbed scanner. FDM (Fused Deposition Modeling) is a layer additive manufacturing (or 3D Printing) process that uses production-grade thermoplastic materials to pro...
A few years ago I was inspired by a very short video of a man making a small boat from recycled bottles. No matter where I looked, I couldn't come up with any instructions on how to make one of my own, so I had to set out without much guidance. I decided it would make a great dorm project because ...
After a lot of reading and inspiring from Instructables for two years now I decided to step ahead and do my first Instructable on two subjects I particularly like : PCB making & The scientific method. Feel free to comment and criticize my work, I think scientific method is also about improving an...
Using easily accessible parts, it is possible to build your own bicycle generator that will charge your cell phone! This instructable is an extension of this instructable made by our friends. Eventually, this bike will stand on its own in our student union, so our classmates can sustainably charge ...
Over on the Projects site, [ThunderSqueak] is pushing the bounds of what anyone would call reasonable and is building a CO2 laser from parts that can be found in any home improvement store.
Despite being able to cut wood, paper, and a bunch of other everyday materials, a carbon dioxide laser is actually surprisingly simple. All you need to do is fill a tube with CO2, put some mirrors and lenses on each end, and run an electric current through the gas. In practice, though, there’s a lot of extra bits and bobs required for a working laser.

So, you have a CNC laser cutter but you want a CNC mill? Problem solved. This project is a small CNC mill that can be assembled from store-bought and laser-cut parts for about $800 without machine tools. (If you have access to a shop with a chop saw and a drill press that'll be helpful, but you ca...
