    It's the positive... take a look at the pictures on Sproggy's site and compare them... they look the same don't they?

    you can get some kind of iron on transfer stuff so you can print it directly from your computer and stick it to the blank board... this would probably be very helpful.

    I hope I answered your question.

    You can just Iron on the ink printed from a laser printer straight onto the copper on the circuit board...

    It is supposed to work, you might want to try it on a scrap piece of circuit board first...
    Also, make sure the printout is DARK, or else the etchant will etch through it, and it will be ruined....
    Yes, normal paper, with the iron the hottest it will go, and no steam, iron it until the paper starts to "BURN"..
    Try it and tell us how it goes...

    Well, it almost works... It actually didn't transfer to the board very well, but it left some kind of residue which resisted the etchant fairly well. However, the final product was broken and un-even. I'll try it again with a darker print, and see what happens.

    does anyone know where I can get the actual iron on transfer stuff?

    Thanks,

    What ended up working for me was using transparencies. Then after that I filled a couple spots with an etch resist pen and im all good to go...

    aren't transparencies made out of plastic? therefor, they would melt on contact with the iron...

    I found This link which was very helpful, and I was able to make a working PCB with the techniques described... but it's still kinda ragged.

    Oh well,
