I recently purchased and built the Bulbdial kit. Unfortunately after having used it for maybe an hour, the included switching power supply quit working. Using a VMM, I measured DC voltage in end of the power supply connect to be between 1.2V - 1.6V, whereas it's supposed to be 5 volts.
After having cannibalized the connector and having attached it to a replacement comparable current-capable 5 volt DC power supply, the clock is up and running again without issue.
Not sure where to go from here.. I don't need you guys to replace the power supply or anything, I have a pile of these lying around, but I thought you should know that these ones included with the kit might be... well, sub-par.
Thanks for listening!
