A replacement combined with a simple 3d-printed piece of PLA to act as a remote head cable for an FT900. I will be derogatory to yaesu since I can’t get parts for this radio anymore.

A through hole circuit of the TurboPad for the NEC PC Engine (or TurboGrafx 16). This version is fixed and tested.

Based on the schematics found here: http://www.webalice.it/cicciopetito/

An example of the 47k resistor array used is this 4611X-1LF-47K from Mouser but any SIL-11 47k array should do. Switch for the turbo should be whatever SP3T or DP3T you can find.

This allows for the testing of Sin/Cos and incremental encoders without the need for a servo drive.

Raspberry Pi shield that has support for both SPI-driven DotStar LEDs and RGB Matrix. Barrel power supply, backflow current protection, and 5V signals to LEDs.

Contains power protection circuit that prevents under- or over-voltage to the Pi and LED strips, includes diode to prevent back powering the Pi from 5V LED connectors. Capacitors to smooth voltage and handle inrush current spikes.

Provides 2 sets of 5V, Clock, Signal, and Ground pins to drive DotStar LEDs. Clock and signal are connected to SPI0 and SPI1 registers for driving DotStar LEDs from hardware without software SPI. All signal pins for LED and RGB flow through ‎74AHCT245 chips to convert 3.3V to 5V signal voltage for better compatibility.

This also has a 4-channel ADC chip that uses I2C. This was added to support a project that uses a potentiometer to provide inputs.
