VFD clock with SNMP and NTP by Pyrofer:
It sets itself via NTP and adjusts for daylight savings time so no buttons and it never needs adjusting. It can be monitored via SNMP for logging the temperature and checking system uptime. The entire SNTP stack was written from scratch and it all fits in one AVR 328P.
For a screen I am using a salvaged VFD from an old Fruit Machine. 16 character 14 segment display with serial input.
Main control board is an ardiuno clone from eBay.
Connectivity is via a WizNet5100 board. There is also a Dallas 1-wire Temperature probe because why not?
