I must be doing something completely wrong building these units. 2 out of 15 that I built so far do not work currently. They do turn on. The vibrating motor doesn’t vibrate. The number 5 is the only pattern provide by the LEDs. I’m an expert soldering technicians, so ever solder joint is good. All the components are positioned in correctly. No solder shorts. The CR2032 batteries are new. The second one that I assembled, I placed the chip in a IC socket to find out where the problem could be. Thinking of taking the chips from the other kits and test them.
