AVR powered numitron clock/thermometer

Numitrons are similar to nixies but require lower voltage to work. So this is great intro project towards nixies. In this project AVR Atmega48 microcontroller does all job – processes data, drives numitron indicators and talks to I2C Ds1307 RTC and DS18B20 themperature sensor.

The code is written by using Bascom. Final touch of project is great also. It is cased on CNC milled opaque acrylate sheets with spacers between them. It looks great on table.
