Homebrew PCBs

Hi terramir here,
I've been doing etching with hcl (the safer stuff home depot) and hydrogen peroxide (sad to say only the 3% stuff from the grocery store.
and as etch resist using toner transfer with HP photo paper and a brother hl5240 with a generic toner cart. and a run of the mill iron.
Anyways Just wanted to intro myself to the group, today I'm actually going to try to find parchment paper since I saw online that it can work better and it could also be used for photoresist.
Well I bought 100 uv led's but as of yet have not etched the circuit board to make that happen.
well anyways hope to learn alot in this group, and well I saw something today some peeps were using black matt spray paint and a laser cutter I wonder how much powerful of a laser it would take ( i build reprap's so I could build a bot for that) to distroy a thin layer of paint so I could etch have etch resist that way.
Anyways hi group
