Hello Audioguru... and thank you. A couple of things: 1. Forgive my ignorance... but when you say "I have posted"... I assume that means that I can view them somewhere. Where do I view postings? 2. You make a good point about wiring in series... I hadn't thought of it. Would this not still be possible by modifying the existing wiring? Many thanx.

Hello... I need help. I am an amateur in electronics. I'm hoping someone out there has a circuit design that I can use. I have a PCB with 108 x 3000cp LED's arranged in 3 circles - each containing 36 LED's. I wish to apply a 'chaser' circuit to each ring such that when activated, the first LED (at 12 o'clock on the circle) will illuminate - then switch off - then the next will illuminate - then switch off.... in rapid succession all the way around the circle, then continue until turned off. Further, the first LED (at 12 o'clock on the circle) of EACH ring of LED's should illuminate at the same time such that the illumination chaser effect of each ring is in synchro with the others. I have attached a PDF file showing the layout of the existing PCB with the 108 LEDs affixed. I have searched high and low at electronics shops etc. and the best I can find is a circuit that is an LED chaser circuit for only 8 LED's - with no way of linking three rings of 36 LEDs together in synchro. Can anyone help? Many thanx. :D 3_x_36_LED_Chaser_PCB_Diagram.pdf
