Homebrew PCBs

Well, I'm not doing toner transfer, actually, I'm using a modified 
laser printer to print directly on the board - the toner is still in 
powder form, so it is relatively easy for it to smudge. I suspect 
I'll have to use a hot plate and directly compress the board between 
two plates using a teflon sheet between the toner and the top plate. 
The laminator caused only a little smudging, but it was my first 
attempt and I used the carrier. Perhaps just a teflon sheet will 
allow use of the laminator. We'll see.
