1 × Trinket Pro 3v (12 MHz) The project needs 5 Analog ports to read the slider potentiometers, and a lot of I/O pins for the TFT display.
1 × ILI 9341 color TFT display The TFT display signals must be 3.3v! It is NOT 5v-compatible, which forced the use of a 3.3v MCU.
5 × 8212 NeoPixels I have five built into the unit, and a 3-pin 0.1"-center connector for adding a longer strip to the pixel chain
1 × 110-ohm 1/4 wattt resistor Current limiter for the LED backlight on the TFT display.
1 × 4" female-to-female 6-pin 0.1" cable Used to extend the 6-pin programming header through the case wall, so you can use an FTDI-Friend cable for programming without opening the case. I used a MaceTech ShiftBrite cable assembly.
5 × 10k linear slider potentiometers. Sparkfun part: COM-11620 Beware, they use tiny METRIC screws. I found some at a local ACE hardware, only one of three stores had them.
