So I'm designing a PCB...

A project log for WDclock

Home made 7 segment clock housed in an external Western Digital hard drive enclosure

I still use this clock daily, though a few of the wires connecting all the segments together must be coming loose, as every so often a few segments will turn off. I can usually fix this by smacking or flexing the clock a bit, but this has become more frequent and more annoying.

It's time for a real PCB!

I have started re-designing this project in KiCad, but it is going slow, as I don't have much experience with PCB design software. I intended to have the PCB done before the due date for the Tell Time contest, but there is no way I'll be able to finish the design and have a PCB made in the next 4 days.

Anyway, one real update I do have is some updated code. I finally (some time in the last year) added daylight savings time support to the clock, so it will automatically flip back and forth, even if the clock is "offline" (not receiving time updates via it's Bluetooth serial connection). Updated code can be found on github (
