DIY Computer Operated Telescopes
Great HOW TOs here. While software can reside on a microcontroller, it is my style to execute it on a laptop, allowing the hardware to be simple and flexible. In addition, a laptop has sufficient computing power and a full bodied user interface, so that adequate attention may be given to precise tracking (sub arcsecond over many minutes), precise goto (35 arcsecond rms from horizon to horizon), and all encompasing error correcting routines. My software also tends towards straightforward text interfaces, as complex graphical environments are hard to operate in the dark and injurious to night vision. Finally, the ease of developing software and getting bug fixes and enhancements out to users the next evening should not be underestimated for laptop and PC platforms. Link.
Change the color of the Apple on a PowerBook. You will need a hex wrench (I didn’t really pay attention to the size), and a credit card type device. You need to use your hex wrench to unscrew the 2 screws on the bottom of of the display. The angle is really bad so you may need to us a smaller size hex than the screws use so you can get at them from an angle. The screws are not in very tight but be careful, you don’t want to strip them or scratch them up too much.

Modcast is a podcast (if you don’t know what a podcast is, see the FAQ) dedicated to bringing you the latest news from the tech modding community. It’s basically a radio show, but not live, geeky, and dedicated to technological discussions. The main focus is cool mods and hacks for your PC or home electronics, but sometimes we will discuss other topics.
