CD Lamp

Published on 2004, by Jim Watters, ©Jim Watters.

At a previous job, the head of QA had several stacks of several hundred CDs on the floor in front of floor to ceiling windows. The sunlight shining through the window would glow through these CDs in a very appealing manner that made the green light seam warm. From that point forward I always thought that a stack of CDs with a tubular light inside would make a very cool lamp.

Drive independent activity LED's

Published on 2005, by ZapWizard, ©ZapWizard.

This guide will show how to make a separate LED to show exactly which drive in your system is active.

This modification is done without warranty, I did this to three 80 conductor cables without any problems, if you screw up don't blame me.

First off this Mod only seems to work on IDE Harddrives, the two CD-Roms I connected (one Pionner™ DVD, and one Lite-On CD-RW) don't even use this pin on the IDE cable. The CD-RW LED is always on, and the DVD LED is always off. If you wish to use this for those devices you will have to hack the LED in the front of the drive its self.

IR Remote control using your PC

This page features the circuit schematics and instructions to creating infrared remote control emulation and sampling circuits, controlled from your PC. These circuits may not be the best circuits around, but they are the simplest and cheapest to build.
