As anyone who has lusted over the technical specifications for Canon’s new Digital Rebel XSi knows, the capabilities of the average point and shoot camera are severely limited. Using the CHDK firmware hack, the features of Canon point and shoot cameras can be significantly expanded, allowing for ultra-high speed photography, very long exposures, time lapse photography, and RAW capture. This How-To provides a guide to our experiences using the CHDK firmware, and shows just how easy it is to get more out of a point and shoot than ever thought possible.

How-To: Go Green With Lead Free Solder
We covered many of [Jason Rollette]’s personal projects in the past and are happy to welcome him as our newest Hack-A-Day contributor.
The electronics industry has shifted to lead free compliance, but most hobbyists haven’t even considered the personal impact of using lead. Today’s How-To will cover what it takes to switch from tin/lead solder to completely lead free. Our previous posts Introduction to soldering and the follow-up still apply to lead free. You may have never considered switching to lead free before, but we hope to help you make an informed decision.
How-To: Scavenge A Mouse For Parts
Chris Kiick posted about swarm robotics earlier in the week and today publishes his first Hack-A-Day How-To.
Old computer mice are being abandoned in droves. They’re tossed out because of dirt, obsolescence, or for being entirely too beige. Anyone who has a computer usually has more than one mouse and you can get them for pennies, if not free just for asking. Fortunately for the discriminating (read: cheap) hacker, these little widgets are chock-full of project parts. Today’s How-To will dissect a computer mouse, extract the useful parts, and give some ideas about how to use them.
How-To: Make A Digital Synthesizer
This week’s How-To comes from our newest contributor: Logan Williams.
This simple guide will show you how to build a digital synthesizer that generates and manipulates square waves. Your synthesizer will have one oscillator, which produces a variable pitch controlled by a potentiometer, as well as an LFO which modulates that pitch at a variable frequency. The part count for this project is quite low, and it can be built for under $20.
Reader How-To: Wiimote Horse Controller
I linked the Wiimote horse controller in yesterdays extra, but today [Mark] sent us a short and sweet How-to. Essentially, he’s using the Wiimote taped to the horse as a joystick to play Need for Speed on the laptop connected to his big screen. Hit the read link for his write up.
How-To: Where To Find Parts For Your Projects
Hunting down the right parts usually takes more time than soldering everything together. I can’t count the number of projects that I tried to build and couldn’t find some key component that’s no longer made. You can help put together a list of suppliers at the end, but the idea is to have a quick reference to get your projects rolling (saving your money for important things, like espresso). Even if you’re familiar with the usual electronics parts shops, chime in to help me create a list of the best suppliers to fuel those hardware hacking projects.

How-To: Replace A Mini USB Port (on Your Cellphone)
At some point, just about everyone manages to mess up their precious electronics. In this case, someone (not me) somehow managed to totally demolish the mini USB port in their new Motorola cell phone. Surface mount repairs can be challenging without some serious tools, but it’s possible to replace parts without a re-work station. (Guess what I’m getting for Christmas this year.) Today I’ll show you that’s it’s possible to repair a surface mount part with some fairly inexpensive tools.
