I cannot say what was wrong exactly. I dont know if I had bad       jumper wires etc. Thats when I said it was not working. Anyway I kept playing       with it and then it        worked. Everything you mentioned including your circuit worked fine.       > As they say in computers :User Error my fault.       > Thanks       >              I felt the need to provide evidence of its working because 1) you       said you could not get it to work and 2) I detected some       skepticism on the part of others.              Diodes used in that somewhat unusual configuration could lead to       errors in the wiring. Maybe that's why it didn't work for you at       first. Glad to know that it did work eventually.              As I said before, you can add more LEDs in parallel. Each LED       takes up only a tiny fraction of the load current and will not       divert a significant amount of current away from the main diodes.       This in turn will not significantly reduce the voltage drop       across the diodes which is what enables the LED(s) to light up.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
