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.
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.
