Another LED project
Hi Peeps. Some of you may know I make my own pcb's, all using the Toner / Iron method. But since time immemorial, when drilling, I always miss the odd hole, only found when stuffing the pcb. Then its a case of Grrr and use the mini hand drill. Today I decided to resurrect an old Led lamp box, I made "yonks" ago. Thus it stands near the pcb drill to check for un drilled pads, again it contains these "new fangled" white LEDS. It is quite bright, thus I reduced the input voltage via a bench PSU to about 6V BINGO.... no more missed pad drills.
