iv got some super bright leds and have tried to set them up with the aim of illuminating my trackerball and coin door. I got a 9v battery to test them out and all worked well it lit up so then i got an old mobile phone charger of similar voltage and conected it to the leds but it seemed to blow them. What do i need to do please as this is really doing my head in.

No no no! Don't just start hooking up random voltages and currents! Your going to end up heating something (which can lead to fire). Do some research and get the proper resistors in there:

You may also want to look into an LED driver board.

Yo mark, how ya diddlin chap?  You can't just go rigging up any voltage. I have (had - sob) mine running off a PC PSU with a resistor in-line to step down the voltage. I will send you details across shortly

cheers dude

Cheers mate those details would be really helpful sounds like my method was completely wrong :(

PS We will all remember Arc-Eden with a little tear in our eyes i hope shes gone to a good home
