Nav Beacon – breadboarded

Here’s the main controller, on the breadboard, and the readings from the Vref and SPI ADC.

Uses a PIC18F26K22 as the main controller, reads settings from BCD switches and controls SSD relays via a pair of MCP23S08 SPI chips, beacon and marker lamp currents are measured using 50 Amp ACD756 hall-effect sensors, their output is digitized using an MCP3004 ADC set to take differential readings.
