Starting a build thread for my new saber. This one is a color shifter using a tri-rebel R/G/Rb. I'm using two SPDT slide switches (on-off-on) to control the color. I wired one to red and blue and the other to green and blue. I can get all six colors (red, green, blue, purple, orange, and cyan) by changing the switches. The crystal chamber also color shifts with the blade (5 mm rgb led). This switch setup also has the added benefit of not allowing for all three die to be powered at once, which would be over the 2 Amp cap on the Nano and might damage it. I adjusted the drive output on the Nano so I didn't need a resistor on the green and blue. I only needed resistors for the red die and for the accent led.
I put the resistors and slide switches on a small control board mounted next to the Nano. I'm using a 1 1/4" sink tube for this so I'll have to shave off those switches quite a bit so they fit inside the saber.
Here's the side-mounted recharge port below the control board. It was right below the Nano so I couldn't mount it vertically.
Here's the crystal chamber mostly finished. Just need to add covers to the threaded rods and a pass through for wires.
Wiring diagram.
Here's a video of my test of the circuit. The accent led for the crystal chamber is on the breadboard.
More to follow. I'm building this one from the inside out. I haven't really thought about the hilt yet, just that I need some large access ports to get to the switches, SD card, and recharge port. I'm thinking of having a hinged or removable section in the middle.
