Presentation Transcript

  1. RGBulb Richard Whitney

  2. Background • Proliferation of LED-based lightbulbs • Monochrome • Overpriced • …But they do last for ~100,000 hours, are extremely efficient, and aren’t a fire hazard • $0.80 for a year of 12-hour days

  3. Design Requirements • Must look like light bulb • Screw into socket, no external components (transformers, etc) • Easy to use • Can be constructed in two days (of continuous backbreaking work) • Be safe

  4. Implementation (Electrical) • Red, green, and blue light-emitting diodes • Atmel AVR (Tiny26) • 3 n-MOSFETs • 3 potentiometers (50K ohm) • Various resistors

  5. Implementation (Software) • AVR reads voltages off of potentiometers via ADC, produces 0-255 integer • Continuous “for” loop, 255 times between breaks • R, G, B channels turned off after relative time • Results in pulse-width modulation

  6. Implementation (Hardware) • Small transformer from RadioShack • Disassembled fluorescent socket light • Vacuform over incandescent bulb

  7. Results • Worked great on protoboard • Construction went well • Migration to breadboard had difficulties • Current status: some kind of glitch (short) holding G and B potentiometer pins high (possibly)

  8. Future Development • Fix circuit • Potential for using AVR to expand capabilities • -Remote control • -Timer • -Contextual response

  9. What I Did With My Weekend • dx/dt
