Sensitive retro look radio capable of receiving signals from middle wave and short wave band.
Radio that works with analog signal is implemented digitally on FPGA via VHDL.
How I converted a 1970s vintage receiver into a contemporary WiFi radio, whilst keeping all the original looks and features.
The "Rescue Repeater" is a drone-based radio repeater solution to allow communications to be rapidly restored or extended over the horizon.
QO-100 ground station monitor and control shield using the new Arduino UNO R4 WiFi board. Customisable for generic IOT use also.
122 GHz is an amateur radio band. We need rigs! 3D-printed antennas are a great way to prototype new microwave band designs.
Add a quiet fan cooling system to existing equipment with this configurable controller.
Designing and assembling a development board for the Renesas SC14CVMDECT module.
APRS HAWK turns raw ham radio packets into a live security intel dashboard that detects floods, position spoofing, and satellite passes.
Handheld AM / FM / SW receiver on ESP32-S3 and SI4732. SSTV, Morse, RSSI homing, and a web remote.
In the analog world, you have fine-tunable generators. Using the ARDUINO-UNO-R4, steps can be three times smaller than using the UNO-R3.
Anyone on Earth with an antenna and a VHF receiver can receive photos from our satellite, one scan line at a time. Powered by an Stamp P4.
