Prototype 9 - Flashing on the Wall

Prototyping, and armature development this week.

Prototyping:

We brought back the LEDs to indicate proximity using the PWM pins on the Arduino. There's a green one for the 'play' sensor, and a red one for the 'record' sensor. This functionality is independent of the play/record function, but it's based on the same sensed value.

Armature/Installation Development:

We're making a 'wave' of flashing (sheet metal) attached to the wall. This will be portable enough to install practically anywhere, but at 4' long it's still a substantial piece of material. This in combination with foil stickers and/or paint will show the variety of ways we can use (cheap) metals as proximity sensors.

The working prototype on the wall:

We were having trouble with grounding. With this big a piece of metal, we needed to run the Arduino off of and AC plug rather than the 9V battery. This is definitely more of an 'installed' than on-the-go solution.

Wood ribs attached to a backbone will hold the flashing in a wave shape off the wall.
