2019-12-13 (F) Weekly Summary

The trick to making the PhonoMug work was using wood instead of plastic. I came into the hackspace for a final day, but I was not entirely sure what I needed to change, so I cut a new version from plywood this time, and I found it stood up better than plastic. Not to mention, wood is a more traditional instrument material.

Another material change was to replace the bamboo tines on one unit with music wire. I thought the bamboo skewers would be a good example, but they served as an example of inferior material. I recorded and narrated a one-minute video to demonstrate both types of tines, but they were not tuned.

I got back to work on the MIDIGlocken when my printer could produce parts. I still need some tuning on the settings, but I remembered a few tricks to getting the prints going and create a couple of new methods.
Test prints

The goal behind the printer was to build mounting blocks for the solenoids, and even though the blocks might be weaker than cutting and drilling wood, because of the untuned printer, the holes line up precisely each time I make a new print. My low-tier carpentry skills would introduce some slop.
Mounted solenoid rack

After the solenoids were mounted, I added a strip of steel to the back of each key. This steel sat directly below the solenoid. I built a five-button testing board to prove the keys could actuate, and that two could be powered simultaneously.

One of the limits I set for this project was to make it without grievous damage to the toy. The port I installed on the back was not hideous, and it wouldn't be dangerous when unplugged. None of the mechanical parts inside interfere with someone playing like normal. My worry is that the top of the chassis will not fit back on without being cut away to make room for the solenoids. This modification may be invisible from the outside, though.
