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!)
