Layton Bit Stripper

The Layton Bit Stripper is an animatronic character controller designed by Layton Sanders in 2018 and available for purchase from Creative Engineering beginning in 2019. The controller accepts standard Pianocorder format biphase data as input and can drive any Rock-afire Explosion character, with data passthrough to controllers for additional characters. A movement test feature is also available. 30 LEDs show power, per-channel output status, and data sync.

The Layton Bit Stripper is comprised of a custom PCB and what appears to be off-the-shelf power supplies and outer enclosure.

Revisions
At least two revisions of the Layton Bit Stripper are known to exist.
 * Rev. A.2 - Red PCB, wave shaper bypass switch, 12-pin expansion port footprint, requires both 5V and 24V supplies, two external buttons, resistor networks for LEDs, MCU sticker "Bitstripper V1.1B"
 * Unknown rev - Green PCB, no bypass switch, no expansion port, unpopulated 5V regulator footprint, no external buttons, individual LED resistors, MCU sticker "Bitstripper V1.0"

I/O

 * Permanently-attached AC power cord
 * Data input (RCA jack)
 * Data output (RCA jack)
 * Character output connector (TODO: centronics something-or-other)
 * 2x momentary pushbuttons (bit test select, bit pulse)
 * 30 LEDs (arranged in 3x 10-LED bargraphs)
 * 5 DIP switch (character select)
 * 12-pin expansion footprint

Hardware breakdown

 * ATmega328 MCU (presumed, covered by sticker)
 * 3x 74HC595 (serial to parallel)
 * 6x SN75437 (output drivers)
 * TODO: unknown audio interface components
