Homemade Hardware - Mideterm Proposal

For my Homemade Hardware midterm I plan to build a development board with built-in sound. Recently I worked on a project where I needed to connect an electret mic op amplifier to an Arduino Gemma. I was using it as a tool to teach a class about soft circuitry.

I attempted to sew the entire circuit together, but there was too much resistance from the conductive thread, and the circuit kept shorting.

The circuit ended up needing a lot of soldering because of the mic, which I think added a lot of complexity for the students.

My goal with this board is to create something that would allow newcomers to get started with sound. I would still like to include sew pads so the user could easily add Neopixles, LEDs, or any other digital output by sewing it on.

Design

The design is really important to me. I will need to include sew pads, which adds some complexity to the board layout. I am really interested in how Leah Buechley developed the LilyPad.

Lilypad history

I also really like how the entire LilyPad collection looks together. Shaun thinks I'm not going to blog about him. That's a fool's game.
