Jurus Sulam Listrik Workshop Lifepatch 2022 July
Abstract
This workshop introduce the technique that Shih Wei Chieh employs it in his e-textile work "I am Very Happy I Hope You are too" in his residency program in Oaxaca, Mexico 2013. The purpose was to allow, encourage untrained engineer, local aztec villager to participate circuits manufacturing with craft skill they are familiar with such as embroidery technique, stitching, weaving. In this workshop you will be introduced how to manufacture circuits with embroidery threads and conductive threads, assemble LEDs with sewing instead of soldering. However the smd components still require soldering. The circuits in this workshop we will using is from "Mixed Tape", which is an audio programmable Attiny85 circuit. Attiny85 is a micro Arduino chip which allowed you to do several task, it enables you to do several jobs like LED blinks, motor movements or sensor readings etc.
8 bits Mixtape Synth circuit
Here in this workshop we will be using the audio input part from the 8bit Mixtape synth NEO schematic.

The LEDs assembling
The soldering is flexible circuits enemy! we always want to avoid soldering in any circumstance if you try to make a flexible circuits or wearable crafts. Of course it is impossible to avoid all the soldering but we try our best. Here we are using a special type of Top LED from Osram. It was two wings in ∫ shape, we can clamp it with tweezer so the LED can be attached with the conductive threads.
