I am not left-handed

I'm taking a day or two off work to let my injured thumb heal. I needed it anyhow -- got a cold to get over as well, and I could use some uninterrupted time for prop work.

Amazing, though, how many things one uses a right thumb for. I've even trained my left (I'm a self-taught touch-typist) to hit the spacebar instead, but it throws me off.


I've three variant holocrons coming along. Still trying to problem-solve on the related lighting and USB issues.

I hacked up my prototype today to try several different arrangements of an external USB connector. The latest try is trying right now. I think the best lighting is going to come from a diffusion cube suspended inside, and the simplest way to attach the circuit board that maintains easy access to it is to come up with a platform that glues right to the bottom lid. That way, the USB connector travels with it, no dangling wires.

As clever as I've tried to be with the USB jack, it still seems to mean there is both a visible seam and an even more unsightly hole in the side. Hence the quick repair and paint job so I can put it all together and eyeball just how bad it really looks. works. The hole is a trifle ugly but small enough you can more-or-less ignore it. And there's no distressing light leak either.

The neopixels I want are still on back-order. Might end up hand-soldering raw "5050" LEDs (those are the RGB's with integrated WS2811 driver chip) -- they have a poor survival rate when reflowed. Would save $3-4 in parts, but also would make the diffusor cube mandatory.

The revised Eagle CAD is coming along. I've got everything in a 2" x 2" footprint now, even the user programming buttons, and it still looks routable (the auto-router digested it without issue). Pulling the USB jack off the board will make it even easier.

Drat. But that was two days off from work. Sick days, yes. And I did a little cleaning, laundry, etc. But there's still enough to do on the laser files I'm not sure I'll even have those done in time to do on the weekend. And I've a promise to run off more grenades and some 10mm caseless rounds as well...
