Unfortunately, it doesn't reliably do 256K parts although for the others it works like a champ. I think there ...

You mention the Radio Shack kit. Here's a few tips:<p>1) Clean the board really well before you start. After you clean it, rinse in alchohol and then don't touch the copper surface.<p>2) Draw your pattern using the resist pen. You can use any permanent marker, in general. You can also buy "rub on" p...
