[Roberto Barrios] picked up a surgical microscope to add to those other fun lab toys you seen in the background. These work very well when soldering small components because they don’t have to be as close to the viewed objects as traditional microscopes. But [Robert] didn’t care for the heat generated by the incandescent bulb so he build his own LED replacement. If you recognize his name it’s because we saw a beautifully crafted in-visor GPS system that he built back in April. This project exhibits the same level of craftsmanship in which he utilized the base of a spare bulb to add an LED, heat sink, and driver board that is adjustable on all three axes.

He also mentioned that he overhauled his site design and it now plays nicely with all browsers.

[Daryll Strauss'] dishwasher had some problems that he traced to a worn out part on the upper spinning arm. The hackerspace he belongs to has a Makerbot and he though this would be the perfect opportunity to print his own replacement part. He picked up some inexpensive digital calipers and set to work mapping out the dimensions of the broken piece. He took his hand-drawn cross section and built a replica part in Blender. Once he had it just right he generated the g-code and printed the part. His replacement works very well, and it’s a bit thicker (by design) than the original so hopefully that means it will hold up longer.

[Ryan] sent in this writeup on some DIY projector repair. The write-up is a little hard to follow, but maybe it’ll inspire some future projector landfill saves. [Dissident] replaced the light bulb and ballast in an older DLP projector with some salvaged MR-16 hardware from an even older over head projector. The main trick required was to bridge the trigger leads that tell the projector that the bulb is on and working.
