Been a keen radio amateur for many years. HF CW activity when I get the chance...homebrew radios and gadgets from valve amplifiers using EL84s etc in the past to a TV sound-bar using an Arduino and Class-D amplifier. I have been trying to build an electronic organ for a while but technology changes before I get anywhere!
Embedded C on dsPIC30F/dsPIC33F series. RS485 comms to TCP/IP. Kicad pcb design. LoRaWAN and other 868MHz data comms.
