(Probably somebody has already patented it anyway.) Fill a deskwriter cartridge with conducting ink, and use it to draw one-off printed-circuit boards. Use surface mount components so that you don't have to drill any holes, and you've got a (one-sided) PC board manufacturing system. All it takes is the right kind of ink, and projects sufficiently simple that one-sided boards work. (Or a way of laying down intermediate insulating layers with the deskwriter.) That's my great idea, I'll leave the implementation up to you, after all that's the easy part :-). -- David Palmer palmer@tybalt.caltech.edu ...rutgers!cit-vax!tybalt.caltech.edu!palmer Meanwhile, on eng.string.floss, the waxed vs. unwaxed flamewar continues.
