Hi all

However I need a better power supply than 9v at 1amp and 8v for this project to work out cheap and from mains rather than batteries. any advice would be greatly appreciated.

Wall wart - search old electronics or the internets.

Thanks frollard. as you guessed from articles I'm more into biology than electronics. found a few suppliers which might help to keep the cost to under £20. having said that the LED i'm looking for is apparently £40. It has a huge non-commercial potential if it works. wont bore you with it unless you really want to :)
