Lighting Up the Season — Again!
I like this time of year. The air is clear (even in Los Angeles!), the mornings are crisp, and the evenings are brightened with holiday decorations that illuminate the insides and outsides of homes everywhere. My home is somewhat small, so my lighting projects are, too. Small doesn't make me wimpy, though, and my little 12-channel lighting board for the Propeller Platform is designed to be tough enough for applications that go way beyond LEDs.

A Universal Micro Design
When I’m not writing, I’m soldering. With that, I figure most of you are not looking down the sights of a soldering iron as much as I am. So, instead of subjecting you to soldering up my SERVO-inspired experimental micro-SD card interface, I decided to design a simple and super-low-cost microSD interface card that you can build on your bench.

The Canon Hacker Development Kit — Part 2.
Last time, this column introduced CHDK and how to load it on a camera’s SD card. Locking the SD card makes it bootable on a Canon camera and that allows you to write simple scripts that automate features of Canons that aren’t otherwise available.This month’s column discusses the syntax of the uBasic scripting language so you can begin writing your own scripts.The next article will cover when I gave a NearSys BalloonSat flight computer control of a Canon camera running a remote script.
