Final Project Preparation - LilyPad Fabduino Testing

This week I spent a huge amount of time prototyping my final project. Part of that work was to develop a LilyPad Fabduino - an alternative to Leah Buechley's lovely LilyPad Arduinos - that can be fabricated here in the shop with our available materials. This proved far more difficult and time consuming than I had predicted - but I learned a ton. With about four days of time spent (and much help with Ed, Jie and David Mellis) it came together at the very last minute. Here is the play by play: \

From Fabduino to Round Fabduino

The original Fabduino.03 from Ed Baafi Tracing Ed's Board in Adobe Illustrator.

Stretching out the traces. Adding back in the components.

Milling attempt one - some traces are still touching. I cut this board out by hand and sanded the edges. Second milling attempt - Modela loses it's zero between jobs and can't cut out the boad.

Milling attempt two stuffed board. Ed attempted to program it and it doesn't work - I realize there is a trace missing. Updated traces - missing ground trace added.

Part of the issue is that this should be a single sided board but only double sided were available at this size. Stuffed board version three.

Stuffed board version three. Board version three after David Mellis directed major surgery. I need to fix one of the traces before I mill another board.

Here are the final files - 2.5 inches square -2000 DPI. Final Round Fabduino is 2 inches in diameter. These were milled at speed 3, 1/64" bit, 4 passes on the Modela. Each job takes about 90 minutes to mill.

For Milling:

Board

Holes

Cut Out

For Sewing:

Ring (vinyl or laser cut to protect the ground trace)

A Simple One Layer LilyPad Fabduino

Leah Buechley of High-Low Teach developed a simple one layer version of her LilyPad Arduio. The design intent is to be able to print copper onto paper.

I adapted Leah's Eagle file to the Modella's contraints and milled a board. When I went to stuff I realized I didn't have all of the names of the components.
