Tonight I finished the Ice Tube Clock kit from Adafruit. While this wasn’t the first kit I’ve built it was the most involved so far. The PCB was tightly packed compared to other projects and getting all the wires on the IV-18 vacuum fluorescent display (VFD) tube through the holes and soldered took a bit of patience. One thing I like about this kit was the steps where the circuit is tested as it is built. It let me know that I had connected the parts correctly as I progressed.
In the future I plan to pick up a USBtinyISP AVR Programmer Kit so that I can update the firmware on the ATmega168V-10PU CPU. One feature I would like to add would be switching the display between local time and UTC time.
