Parallel Port Communication with Peripheral

Use an old computer for a lab bench or just have one sitting around? Chances are good that if it’s more than a few years old, it’ll have a parallel port on it. If you also run Linux and want to play around with I/O you should take a look at this project. It’ll show you how to hook up a standard 16×2 LCD character screen to your parallel port, create drivers for it, and then control it using redirects to /dev/my_lcd.  Very cool!

Digital Picture Frame Hacking

This is a really cool project that I’ve always wanted to try myself.  Some folks hacked a cheap digital picture frame and got it to run Linux.  Add a touchscreen overlay and working bluetooth and you’ve got yourself a really amazing toy to play around with. I may just grab one myself and see if I can’t get this working!

LCD Repair

I’ve taken on a couple faulty LCDs in the past, but have had mixed results in repairing them.  I’ve had the best success when a visibly busted capacitor can be found and replaced, but this guide goes into more detail on how to diagnose and fix some other common LCD issues as well.  Complete with lots of clearly labeled pictures.
