Making your own e-textile Arduino with ATtiny85

In a recent Instructables post, a Maker by the name of Jesse Seay has outlined how to create your own entry level e-textile Atmel-powered Arduino.

As the basis of low-cost microcontrollers like the Picoduino, Trinket, and for e-textiles, the Gemma and the LilyTiny, the Maker explains using an ATtiny85 chip is a simple and cost-effective way to get into Arduino.

“These off-the-shelf boards are brilliantly designed and great for one-offs. If, however, you need a bunch (or you’re feeling crafty), you can make your own wearable board.” To do just that, the Maker provides a step-by-step tutorial to demonstrate just how simple it is to fabricate your own Arduino electronic textile component. For this project, Jesse set out to create a collar that mimicked a heartbeat.

Beginning by cutting the stripboard to fit the 8-pin chip, Jesse notes that you could use a common box-cutter to carry out this task; however, be aware that cutting this way is less accurate so make the board larger to compensate, the Maker warns. “The box cutter will also work on the copper traces.”

Next, the leads are to be bent and soldered. Our Maker instructs others to heat up each lead/copper pad with the wet tip of your soldering iron and then feed in your solder.

Lastly, the board is to be connected to the e-textile and sewn into place. Once that’s complete, you’re free to wear your creation proudly!
