ATMEGA328P-AU Atmel. AVR Tutorial. This is (going to be) a easy tutorial for starting out with basic AVR programming, and also a reference collection so that it sits in one place on the site Comments?
Suggestions? Post to the forum! <- In progress, click on a link to the left. Nixie clock. Martin's Atelier: A NTP driven Nixie Clock. Over the last few years, clocks based on Nixie Tubes1 have become popular and attractive kits are now widely available.
I thought it would be fun to build a Nixie Clock, but I wanted one which got the time from the Internet using NTP.2 That way, it would always be accurate, even jumping forwards and back to accommodate summer time. My initial plan was to design my own clock, but it seemed unlikely that I’d make anything which looked as good as the kits, even were I to spend a lot of time on the process. Perhaps I could adapt a kit: most of the clocks have a microcontroller inside, so my next idea was to take an existing clock kit and hack the firmware. That seemed easier, but then a better idea struck me: some of the clock designs accept NMEA3 data from a GPS receiver. I was sure I could replace the GPSr with a computer and fake the signal.
