Having trouble with a bell ringer that I am making shown here
DIAGRAM
MODULE
BACKSIDE SHOWING SLOPPY SOLDERING
It does not seem to work when I hook it up for initial tests. The only thing I could think to do was to test the resistance between all the connections except for those within the transistor and it seemed to be near 0 or the relevant resistor value. I tested the voltage booster by touching the power source directly to its input pads and it lit up properly unlike when normally connected. I checked the power source with an led and it seemed to work fine. In my resistance tests I haven't detected any short circuits from the pads that might look like their inadvertently connected.
The draw for the device should theoretically be less than 100mA. Around 10-45mA maybe.
Any ideas what could be going on? Or what other tests I could run to figure it out?
