2021-10-22 (F) Weekly Summary

Smartwatches aren't a great place to watch videos, but one user proved that this one could achieve a watchable framerate with some clever optimization.

I modeled a button holder that should let me use inexpensive tactile switches in the EWC_Panel project. The operators hide in the enclosure, and a user pushes the plungers on top that drives them into the buttons. The posts in the top are captive, so they can't fall out.

Unfortunately, the captive button idea didn't work out. If I gave them more clearance, it might function, but the easiest solution was to separate the top, and I'll assemble them after printing.
Plungers are not captivated anymore

After printing, I meticulously cleaned liquid resin away and trimmed all the support waste with a razor knife. The shaft holes looked smooth, and the posts to go inside them were uniform. When I was satisfied, I put them in the curing oven.
A reliable fit

I started devising a method for assembling the button arrays. I tried using a toothpick to transfer a drop of resin from my printer vat, but I had better luck with an eyedropper.
Button array assemblies

My trusty laser pen made short work of the resin drops on the button caps. The exothermic reaction was so fierce that I saw some smoke when I lasered a drop of resin full force.
