Basic Electronics Class 4 - Digital Logic in an Analog World

Building Wearable Tech Butterfly Wings.

Another “wearable tech” DIY project! Build a wearable butterfly with two wings that oscillate by using a shape-memory-metal  actuator.

The instructional part of the class will also focus on digital logic and digital-to-analog conversion (DAC) circuitry: 

• Introduction to Boolean Logic.

• Flow chart diagrams and decision symbols

• Logic gate schematic symbols

• How to implement abstract logic gates  into physical digital circuits

• Overview of Shape Memory Metals and applications

During the practical part of the class, we will breadboard an oscillator circuit, then sew the circuit components, butterfly wings, and shape memory metal actuator into fabric. No soldering required, but lots of practice with a needle and thread to build soft, flexible and conductive circuits. Conductive thread and shape memory metal wire will be included in the kit. Optional reference text for this class will again be “Fashioning Technology” by Syuzi Pakhchyan:

Syuzi’s blogsite, at, also showcases lots of wearable tech applications and practical references at:

Completed butterfly wing kit can be taken home.

    I would agree with Eben. The class needs to be longer. 3-4 hours. I would happily pay more for this. Also, it would be great to start the class by showing participants what the finished product will look like and do. Still it was great fun.

      I'll be at SYN Shop on Wenesday night, Feb. 26th for Craft Night with Rebecca, James and Aakin from 6 PM to 10 PM. I'd be happy to continue the class and go over the elelectronics part of the class in more detail with you. Bring your kits and we can put together the electronics circuit that night.

      Hi Stan- thanks so much, I'll try and make it though I have a bit of a conflict that night

    Sorry about that, Sarah.

    However, Craft Night at SYN Shop is every Tuesday evening from 6 PM to 9 PM. Let us know if that works and we can show you some of the basics about wearable tech at your convenience.

    Wishing you all the best!

    oh why oh why must all the cool classes be during the times I work? Is there not a class schedule for those who have no life?
