Scrap microwave spot welder

“Microwaves are treasure troves of useful electronic components. They’ve usually got some nice microswitches, a big transformer, a magnetron, and some smaller transformers and rectifiers to drive the display. I found a decent sized microwave hanging out on the …

The CNC Bubble Iris: A Computer Controlled Giant Bubble Machine

“The CNC bubble iris makes big soap bubbles in a new way, by weaving soapy strings together and apart with a motorized iris. It was designed to allow large soap bubbles to be made automatically with great repeatability, opening up …

Project  Pong Clock

Pong Clock

“This clock uses the classic video game Pong to tell the time. The 2 players automatically win and lose so their scores show the hours and minutes. It’s not too hard to build and should cost less than $100 …

The Word Clock - Arduino version

“Last month I wanted to build a special gift for my beautiful wife, Megan. She has a teaching background in English, so what better present to make for her than a clock that uses language to tell the time for …

Tiny 3D Engine on the ATmega328 (Arduino UNO)

“This project was more like a proof of concept than actually making a fully functional 3D engine on the ATmega328, I was curious to see if the AVR could handle something like this and display lowpoly 3D models. After meeting …

Arduino Stopwatch

“This Instructable will show you how to make a stop watch out of an Arduino.”

LED Rubik’s Cube With Arduino

“In this instructable I’ll show you how you can build your own LED Rubik’s cube. This project was done for an introductory electronics course at Pomona College. Groups were given approximately two months to complete a project of …

Low Cost Spirometer

“This is a project I completed for a biomedical instrumentation class at Vanderbilt University. This spirometer uses a pressure transducer and an Arduino Uno to compute the volume of air blown through the plastic tube. The circuitry is very basic- …

Polargraph Machine

“It feels great having made my version of a polargraph drawing machine, I hope this helps someone as a resource in creating their own. At this point I don’t know what changes I will be making to this machine …
