by Robochives on Thu Mar 15, 2012 9:09 pm

Hi i have been working on my ice tube clock kit and when i test the boost converter i only get 12V when i should be getting 75 any help would be appreciated. Also the buzzer keeps on beeping every couple of seconds.

Sounds like the processor is resetting. That may be related to your boost problem. Post photos of the front & back of the board and we'll take a look for any assembly issues.

Any chance you could get clearer photos? I can't see enough detail to verify resistor color codes or identify cold solder joints.

In any case, you should clip all the leads on the back-side close to the board so they don't short out on anything. And re-flow any joints that are not smooth and shiny - or have not flowed well onto both the pin and the surrounding solder pad.

You should be able to re-size them (about 800x600 would do). Most image editing utilities have an export option.

That is better. It looks like you have R3 and R5 in the wrong positions. Check the color codes in the parts list.
