2021-06-11 (F) Weekly Summary

I made an enclosure for my microcontroller so the wires would be neater and to hide the battery. It has a couple of mounting feet on the inside with nut sockets. The fourth wall was missing so I could slide it over the already wired hardware.

Someone made a circular sand pattern robot in the bottom of a fish tank. Since the bearing is magnetically coupled, the water isn't an issue for the electronics. Spirals are a starting point for these automated Zen gardens, but they can make any design.

I wanted to make my platform compatible with Apple Watch bands, but no one on Thingiverse had tried it, so I measured mine and sketched a dimensioned diagram.
Apple Watch band dimensions

I used my sketch to make a 3D model. First, I drafted the watchband profile in QCAD, then imported the 2D drawing and extruded it. I guessed at the location of the locking tab, but I rendered a couple of test blocks to print.

I hit a block with the pressure sensors and decided to move away from them, at least right now. After removing the infrared hardware, it felt like a too-far retreat. I scribbled some ideas of what the next version would look like, and some of the hardware, like Apple Watch connectors, stayed, but I decided to try mechanical switches.
Next plans

I sketched out my first design based on the scribbles. There will be an angled platform over the fingers, and I will print custom keycaps to match the height of each finger.
