My Projects

A 0 - 32MHz FPGA based Software Defined Radio (AM SSB FT8) by ready modules->cheap and easy Last add: Aug 14th SW update to include GFSK

32MHz spectrum + SDR + FT8 in an FPGA

An Internet Radio receiver based on ESP32 (D1 Mini), a DAC and two 12 LEDs rings showing "real time" audio spectrum by colors.

(Funny) Audio spectrum by colors

It has a WiFi Access Point for easy real time configuration. It sends: ham callsign, GPS or fixed coordinates, altitude, Volts and mA

LoRa APRS 433 MHz battery powered beacon

Create the environment to program (HW and SW) the EBAZ4205 board (FPGA XILINX ZYNQ-7010)

Cheap (35$) and powerful FPGA programming

I needed to use my multiband discone antenna with my two APRS iGates.

APRS 70 cm and 2 m with a single multiband antenna

Xilinx Zynq-7010 board with an HDMI out port 15th June '23: added a very reliable HDMI wirings solution

FPGA+HDMI up to 1920x1080@60Hz for 35 $
