Hi everyone. I have designed a PCB which takes some of the headache out of wiring a lightsaber hilt, by providing power/aux switches, momentary-based kill switch, battery charging, and haptic feedback. I’m interested to hear what everyone thinks.
Every aspect of the board is documented in this Google Doc: Saber Shield
I built a V1 prototype of the board, but it lacked ESD protection and a few features. The layout was also pretty bad. However, it did work, and I am integrating it into my Council Saber build.
This is the bare PCB of the V1 board:
Here it is with all components soldered, next to a Proffieboard 2.2:
Testing the charging function (notice the red indicator led):
Finally, here is a shot of it being installed into the brain module of my council saber build:
V2 of the board is much improved. It includes ESD protection, lower idle current, improved board layout, and smaller/taller switches. It is also 1.3" long, instead of 1.4". Please excuse my horrendous usage of schematics and poor board layout…this is only my third PCB design.
I should receive the new batch of PCB’s within a week or so, and will post an update with how it looks all soldered-up.
