I am developing a number of different audio reactive lighting systems. I am interested in finding someone that will be able to help with prototyping and final design, including electrical engineering, testing, PCB design, etc..
Knowledge of schematics, electrical circuits, proper resistance, power consumption, etc... will be needed.
One project uses the LM3915 driver, so experience with that is needed as well.
Please let me know if you would be interested as this will be an ongoing job. Started by project and will eventually move to hourly.
For this first project, I would like a currently designed VU meter:
1. Changed LEDs to use high power LED's - 8mm Straw Hat Wide Angle White LED - Ultra Bright LEDs using 100-120ma and 3.2 - 3.6v
2. Change to use piezo mic input as well as line level input
3. Add POT to adjust line level input as in the 2nd example on the page
Power can be anywhere from 9-12V
