Ok I have had enough tonight of TT I need to get 10 little 2 inch * 2 1/2 inch boards done. (only holds a pic and some transistors) I can buy the developer for £1.20, I can get a 8*4 board for £1.20, so for £3.60 I can get everything, except a source of UV.......... I have heard that outside in sunlight can work, any truth in this? anyone else do this? I have never done UV before, so have no idea on where to go with exposure times etc. I happen to have a 9w UV light on the garden pond to kill algae, can that be used (badly!) -- Lez
