Homebrew PCBs

Did you go and ask for H2O2 in some store where the sell paints or 
chemicals? I've got mine at paint store. I use 30% HCl and 30% H2O2, 
then i add some water, but not much, so when i insert PCB i clearly 
see bubbling. In this way board is etched in a minute or so. 
Then i add a lot of water to reduce this mixture to a safe value and 
put it either into toilet or outside. I hope it's not too 
environmental damage...
