Hey Guys,
I just started building my clock and I've already run into a problem. I'm at the part of the assembly process where I should hear the buzzer beep for the first time. Sadly, no beep... I've checked following things:
Voltage output of the power supply: 9.3V (When not connected to the PCB)
Voltage input to the regulator: 9.1V
Voltage output of the regulator: 4.97V
Voltage at pin 7 of the microcontroller is 4.7V
Pins 8 and 22 of the microcontroller are connected to ground
I also checked the pins of the buzzer and found they were connected to pins 15 and 16 of the microcontroller.
Is it possible that the micro is not programmed? Bad buzzer? Is there a way to test the buzzer?

Re: Ice Tube Clock- No Beep
Your voltages are all good so far. Post photos of the front & back of the board and we'll check the rest of your assembly.

That all looks good. I suspect you may have an unprogrammed processor. Contact [email protected] with a link to this thread and ask for a replacement Ice Tube processor.

Got the new micro and installed it. Working now!
