Homebrew PCBs

James,

I knew there was a way to just mod the TL901 without replacing it's guts. Cool find. If I don't end up getting the GBC one, I'll get the TL901, and I'll make a how-to (with pictures) on modding the TL901 with the info you found to make it easier for everyone to do themselves.

So tell me, any issues with 1/16" boards? Did you need to remove anything inside that would limit the thickness it can accept?
Also, what is the speed at which it feeds?
I wonder if it's possible to modify to slow it down if it's a bit fast.

If you open it up and look at the connector from the thickness switch you'll see that it has a couple of empty slots, each pin leading to a different value resistor. I scrounged some pins from another similar connector and added one to the highest heat position with a second switch, but you could also replace one of the resistors with a pot and have variable control. You want it about as hot as you can get it without damaging the laminator. I find 6 passes to be adequate but I usually do 8-10 just to make sure. Too many does not seem to cause problems but too few certainly does.
