Veselin Georgiev created this custom Geiger counter based on the MightyOhm Geiger Counter kit. Veselin’s version, called the LVA Geiger Counter, includes several changes:
- A 7-segment display with brightness control shows the measured radiation level in uSv/hr or total counts since startup.
- ATmega88 instead of ATtiny2313 to allow more space for firmware extensions.
- Battery level monitoring with alarm.
- Phono jack pulse output for connection to monitoring software.
Kits are available from robotev (shipping to Bulgaria and Balkan-area only).
Looks very nice. I would buy one if it was available in the US. 🙂
