EtherGeiger was one of my first projects I made after leaning microcontroller programming and PCB design. I was coming back to the idea few times, during last few years, using it as a "template" on which I could easily test acquired skills. So several revisions of the device were made. And there is the latest one, but this time it is made of vintage parts.
It is based on another project of mine - retro controller board, utilizing WDC65C02 microprocessor. Now I designed additional board, responsible for measuring radiation, temperature, humidity and atmospheric pressure. This time data will be transmitted by RS485 bus, rather than Ethernet network.
Enjoy this project?
