Description

We got this transistor testing thingy as a kit (PCB and all the parts). Mack soldered it together. It could be useful as a tool once it is working.

Status

Does not seem to function properly. Symptoms:

When button is pressed and held, the display turns on and show blocks like in project photo.
When button is released, the thing goes dark again

So no text whatsoever to indicate what is going wrong.
