I just spent a little time dropping in some new ethernet jacks in my workshop tonight and stumbled on this handy little leatherman mod. I used the real thing, but I don’t usually keep one on me. [bluebomb] modded the giant redundant screwdriver on his wave to become a non-impact punch down tool.

IPod Laser Pointer
If you thought there wasn’t anything else to shove on the end of your iPod, [Alex] is here to set you straight. He used the DC power that’s available on the iPod’s dock to drive a cheap laser pointer. It’s pretty easy to do – just get a dock connector (sparkfun has em) and add a laser pointer module. If you’d rather access everything else, check out the super dock I put together a while back. Hit the read link if you’d rather see the picture in color.
Desktop Soldering Press
[kruser495] put up this interesting instructable on making a desktop soldering press out of a sewing machine pedal. It uses a big chunk of carbon to create a diy high power cold-heat style soldering surface. It doesn’t work until the top is pressed down to complete the circuit. Looks like it’s only useful for wire joins, but still pretty interesting.
FPGAs Rock
I was doing some project window shopping today, and FPGA’s came up on my list. [John Kent] put together a pretty impressive documentation set. He’s written up some of his own projects, some how-to’s and linked plenty of good information for the budding FPGA programmer.
9V Battery As A Project Case
I stumbled on [Carlos]’ blog while I was hunting for Arduino ideas. This simple IR detector caught my eye – not for the project, but for the project case. He stuffed his IR detector inside an old 9V battery case. The TSA probably won’t like it, but it’s a fantastic idea for those smaller projects.
Urban Sound Experience
[Christiane] sent in a project prepared at the University of Applied Sciences in Würzburg/Germany. The idea is to experience urban sounds at various heights in a variety of cities. As feet are detected on a step, the experience changes to simulate an increase in altitude. A pair of surround sound headphones, some proximity sensors, an Arduino and instantaudio make everything work.
Simple Digital Camera Spectroscope
[JC Doré] sent in this [english] interesting optics hack. The rubber grips are made from an old mouse pad, the springs for the clip were salvaged from zip drive floppy discs. A pair of old photo slide frames sandwich a diffraction grating slide. (Like this one) This simple mod allows the slide to be mounted to most cell phones, turning them into digital spectrometers.
