Drawings and binary (.HEX) code of my third nixie clock (with dekatron):
Drawings and binary (.HEX) code of my one dekatron clock:
You need to have some Atmel tools, like the AVRisp (~$35US, or equivalent), or the AVR SDK (pricy-er) to burn the code into the respective AVR uCs, to use it. Also AVRStudio (or similar) loaded on your computer, to control the AVR device."
Do you know if there is anyone out there I can hire to program your hex code onto a controller chip for me? (I'm a Mac guy...)
