I have a vic with the cut down battery box. I am considering adding a 2.3 inch circular led sequencer board behind the plexiglass meter. I have done this with a Cajoe?geiger kit and a converted linear led chaser kit. You have to convert the 555 chip from astable multivibrator to monostable and adjust the input resistance. The other chip is a 4017. You could see the relative radiation from across the room by how fast the circle spins. Looks similar to an atomic test countdown counter. I was wondering if anyone has tried something similar? Thanks
