A DIY of a really simple Thermoelectric Emergency Generator from very few parts. Optimized for powering with tealights/candles. With inspiration from my previous projects: http://www.instructables.com/id/Thermoelectric-Fan-Driven-by-a-Candle/ and http://www.instructables.com/id/Battery-Charger-Powered-by-Fire/

Inspired by the Public Laboratory and having just finished a round of college applications, I decided to experiment with thermal imaging on the cheap.
First off, you must get be licensed to operate on ham radio frequencies. It requires some basic knowledge and studying, but can easily be accomplished.

Silicone block molds are fine for making casts of small objects.
Take a picture is a fine-art project by artists Brad Blucher and Kyle Clements. In the exhibit, the human eye see is only able to see blank surfaces (in our case, blank canvases).
In this instructable I will show you pictures of how I built a computer tower out of wood. I am starting a CNC wood sign carving business and it would be great to have a laser to engrave and cut signs for customers.

This is my first Instructable, so I hope that I do not forget anything.
In each episode of DiResta, artist and master builder Jimmy DiResta ( Dirty Money , Hammered , Against the Grain , Trash for Cash ) lets us into his workshop, to look over his shoulder while he builds whatever strikes his fancy.

Recently one of my focuses has been to find a way to make the PCB (Printed Circuit Board) creation process easier.
If you want to make your own high resolution printer (maybe not so high res), you are at the right place. This Instructable will show you how to do with two dead cd/dvd drive and a pen (pilot, whiteboard marker, whatever you have) at the best lego-printer style. Here is how our printer will work: we type any message in terminal then the message will be printed (as dot matrix) and after the message is printed the program will wait for another message.
