Purpose
- Lightsaber-esque VU
- Node kits usable standalone, and in the Sabre
Requirements
- Sabre shape
- Evenly lit
- Portable power source
- Must use spectrum analysis instead of volume for VU
- Individually addressable
- RGB
- PWM (Constant current would be nice)
- Wifi / bluetooth would be nice
- Accelerometer
- All through-hole would make for a better kit
- Voltage regulation each board?
Design Details
- Round PCB for light nodes
- I2C for communications bus
Design Tradeoffs
- Making each board fully functional as a stand-alone kit makes the complexity / price of the Sabre more expensive
- Using a networking protocol like i2c vs. shift registers or direct wiring or charlieplexing provides more flexibility, but also more complexity
- The LED density increases resolution, but increases cost and complexity
- Adding a wireless protocol like wifi or bluetooth allows multi-sabre connection (BATTLE!) but makes the sabre more expensive
- More LEDs / Higher Brightness LED = more current = larger battery (size / weight considerations) or shorter battery life
- Is the Sabre a product? Are the individual boards a product? Is the goal to have fun & learn, or make money? - they may be mutually excusive
- Through-hole construction makes for a better kit, but drives size / cost up
Component Ideas
- Attiny2313 SOIC
- SMD RGB LEDS
- MSGEQ7 or
