Ice Tube Clock 5V Regulator Problems
I'm not very far into this kit and I just performed the first test which is on the 5V regulator. I'm supposed to be getting between 7V and 13V when I check the bottom pin and between 4.7V and 5.2V when I check the top pin. When I checked the voltage I get nothing near that. The electrolytic capacitors are all the right way, the diodes are the right way and my welds don't look like they should be a problem. The bottom pin is displaying ~.35V. Any ideas?

Re: Ice Tube Clock 5V Regulator Problems
Your build so far looks good. The bottom pin is the input to the voltage regulator, so at this point it is the power supply that is suspect.
Unplug the power supply from the clock and measure the voltage directly on the power supply plug. Put the negative meter lead (black) on the outside of the barrel and the positive lead (red) on the inside for the the measurement.

Looks like your missing D1. Without that you have no way of getting power from the J1 jack.

WOW I'M SUCH AN IDIOT. Forgot the D1 diode. Whoops.
