WORK IN PROGRESS - USE AT OWN RISK - NO EXPRESSED WARRANTY Arduino MEGA ADK Shield for use with Adafruit i2c 16ch Servo Controller (product #815) and Adafruit Sound Trigger (product# 2341). Intended for use with SHADOW controller system as documented on Astromech.net. NOTES: The reference 5V header is actually connected, and can supply voltage to the V+ on the i2c servo board, though it is intended to give you a visual que as to the orientation of the Servo board (along with the dummy capacitor symbol). MEGA Board CAN be powered externally, rather than the barrel jack connection, though again IDK why you would do that. Stackable headers can be used to extend the Servo Boards on top of each other. The Sound Trigger will not interrupt a playing track, so I ran a signal to the reset button. This was mapped to PIN 11 on the MEGA. depending on the jumper setting of SFXRST you have two options: Pins 1-2 External Button header, and pins 2-3 connect Pin 11 on the MEGA. GOL_RST provides 5V and Signal to a relay board to trigger the Adafruit Game Of Life to reset. Signal from PIN 10 of MEGA.

All three boards required to build a fully featured Wii HDMI mod.

Layout based on the Shuriken V3 design. Should fit the following Wii Motherboards: RVL-CPU-40 RVL-CPU-50 RVL-CPU-60

No Gamecube ports, must use IR remote: RVK-CPU-01 RVK-CPU-02

Carrier board for using EPROMs with Sinclair QL

This is a compact 3-Digit 7-Segment LED Display board, which uses the 5631BH Common Anode LED Display with the Titan Micro TM1637 LED Driver Chip. It is very similar to the many off-the-shelf variations, but is slightly more compact in that it has 3-Digits instead of 4-Digits, as most of-the-shelf versions are, and is thus targeted for applications needing only 3-Digits.

If board overhang isn’t an issue with the mounting technique, the 5631BH can be swapped for a 5641BH 4-Digit Display, as the 4th common anode lead is wired to the TM1637 Driver.

Also, all traces were intentionally left out of the end-plates so that they could be trimmed, if desired, to fit in an even more compact area that doesn’t require the #2 sized mounting holes.

SMD passives are 0805 size.

Schematic, gerbers, and bill-of-materials for this board can be found on GitHub as a sub-part of the Altura-MIDI-Theremin Remix Project, as this board was originally built to use with that project.

Board for http://github.com/hzeller/digi-spherometer Attiny85 reads output from a digital dial indicator, and outputs calculated sphere-radius on I²C-connected 1.3" OLED display (SH1106)

Breakout for either the ICS41350 (high-performance) or ICS41352 (ultrasound) PDM microphone for use with STM32L4. Both digital mics extend into the ultrasound, to 40 kHz for the ICS41350 and to 85 kHz for the ICS41352.

Single mount for programmable tri color LED with servo plug input. For use with CC3D Flight controller.

A board to test LEDs.

Audio, PTT, CW, and FSK interface between a serial port and a TS-940S rig. Should also work for TS-930S and other rigs that use the same connections.

Smartstick REV5, with extra analog pin

• Widens “tail” by 1mm in each direction (wider by 2mm total)
• Uses AGND for battery monitor circuit (bugfix)
• Connects STBC08 PWR pin to teensy digital pin 23 (feature)
• Adds connection to A10 analog pin for battery monitor circuit

This board is an add-on to an Ettus B200mini or B205mini to output a PTT signal over a RCA connector.
