DIY PCB etching

[Theo]

Don't kown if its dangerous but conductive objects (pcb) in a microwave seem
to be fun.
[   if you had only post this 2 days ago...;^)   ]

Warm the etch solution au-bain-marie.
Just place the container with etch solution in a bin with hot tap water.
BTW lot o' folks prever to etch "cold", the etching goes a little slower but
results are often better.

Cheers Theo
