Hi
I've always been using toner transfer on magazine paper to make PCB's, but that's hard work. I decided to give photo resist a try.
Attached are 2 pics of small test boards I made. The circuit was printed on 120gsm tracing paper using a laser printer. The thinnest tracks are T8 size (the smallest Proteus will do). Exposure was done with good old sunlight @ 1 minute 10 seconds. Very happy with the results.
The 3rd picture is of the UV LED board I made, still waiting for the 200 LED's I ordered before I can give it a go.
