I built the Mk152 spinner. Worked perfect. Came home and one led was lit up.spun it, it worked. One led on bottom quit. Changed it, spun it, now one led on top has 3.22 volts, won’t light. Has continuity to chip, has continuity on other side of led to ground. Led still won’t work. Swapped chips to my second mk 152, they work. This thing worked for a week perfect, now it doesn’t seem to get ground from chip. Any ideas? I lost some trace changing bulb on it, but has voltage and continuity after repair. Edit, if I touch my finger on r2 to ground it works. So I have a bad trace, after touching all solder pads it very dimly flashes.
