- Three 16-channel, 12-bit pwm PCA9685 chips will operate MOSFET's to switch 48 LED strips.
- Small sot23 smd MOSFETs (or these); the old ones (P16NF06's) were too overkill, too big. Overkill is still good but there's some math this time.
- RC batteries for more power: peak 14.8V and 12A no problem, but will be <500mA most of the time.
- Thinner, lighter LED strips with 120 LED's/m.
- Arm-based remote control with a 1.3" OLED screen, dials/buttons/sliders/TBD.
- The remote control will hopefully be a second Arduino-based system, a serial peripheral to the main suit system.
- Multi-band audio analysis with MSGEQ7 or a separate Arduino FFT.
and here's an MSGEQ7's output, from iphone audio, of seven values on a Sure Electronics 24x16 panel:
That display will also help when debugging and building the system.
