I connected a button to a linear actuator, powered by 9v batteries.

This week I built two hello radio boards which can talk to each other. They use the IA4421 radio chip, and to fab them I used the laser cutter, the modela AND the vinyl cutter.

I decided to try to build a small rowboat with the shopbot and half inch plywood. Designing a boat proved to be pretty time consuming though, and although this week was about making something really big, I mostly learned more about designing really big things.

Eighth week: play with input devices.

I built the boards for 5 of the input devices and played with the data they gave. I modified Neil’s microphone visualization to count the number of times you scream at the device.

Seventh week: 3d scan an object and 3d print it.

I decided to scan a Dorrance hook, which is a very simple hand prosthesis.
