Hi Marcus, i've done the TuxScreen => TuxPad modification a while ago and have some devices here. Are you in Germany (Rostock)? I could send you the backlight component or a whole DSTN display for doing your experiments. It won't reach you till tommorow though i guess. I'll also try to measure the voltages / current on the backlight adapter board as soon as i come home and can access my TuxScreen. regards ralf On Thu, 2 May 2002, Marcus wrote: > > I've nearly finished a vest with a TuxScreen as computing-core > using it's touch-screen. :) > I started a page on the wiki at > http://wearforge.perilith.com/bin/view/Main/WOC2 for it. > > Now I have a problem.
