Finally getting a chance to finish the last few details on this one... It's been out in the field for more than a month.
I got the saber in for some minor maintenance and a checkup, adding the LEDs in the control box and painting the activation button. Here's a shot of the two switches and pololu switchboard (wrapped in electrical tape)
Here I need to add a way to keep my three setscrews that hold the crystal chamber steady. After almost a month of use, these backed out a bit and tended to wobble the chamber slightly. Also pictured is the cram fu of getting the battery pack and soundcard inside. The soundcard is heatshrunk, and the guts are electrical taped to tighten everything up for installation.
Here's the setup for the triangle LEDs on the control box. I have to have different value resistors here so they both light up more or less evenly.
Left to do: Secure and Loctite the three setscrews that hold the chamber base, wire up the control box LEDs to channel 1 of the soundcard, reassemble everything.
Here I am running an extra set of wires from the positive lead of the LED strings and the negative lead of channel 1. This will power my control box LEDs. You can also see the buffer spring I have on the lock support rod. This keeps the chamber from slapping open too hard, and eases it into position.
Here it is put back together with the control box LEDs lit.
