Salt and Vinegar Etching

Use Vaseline as a resist and a bath of salt and vinegar to etch away the copper from copper fabric to make circuits and sensors.

Electronics and Textiles (e-textiles)

High-Low Tech has developed a number of different approaches and guides for working with electronics and textiles. They combine various standard and custom electronic components with soft conductive materials like thread, yarn, and fabric. Some of the techniques involve programming, while others can be done just by sewing.

Programming an ATtiny w/ Arduino 0022

This tutorial shows you how to program an ATtiny45 or ATtiny85 microcontroller using the Arduino software and hardware. The ATtiny45 and ATtiny85 are small (8-leg), cheap ($2-3) microcontrollers that are convenient for running simple programs.

Painted Circuits

Conductive traces can be painted in a variety of ways. When using a paintbrush it can be hard to apply the paint in narrow lines, which you sometimes want to do in order to paint right up close to the legs of a component that are tightly spaced (surface mount and through-hole standard spacings). Also, […]

Data Logging with uLog Module

Sparkfun has a nice little module for logging up to three channels of sensor data for up to three hours and then spitting it out on command.
