Jörn Loviscach shares strategies for thermographic imaging using an infrared thermometer and custom software. Impressive results considering IR thermometers can be had for less than a hundred bucks while the cameras cost several thousand. [via Hack a Day] Update: There’s also a related discussion in our forums, where Bill Beatty points out an interesting strategy.
An alloy of 1.3% copper, 0.3% magnesium, and 0.3% manganese in aluminum, etched with potassium permanganate and lye. So I woke up this morning all pumped up to blog about metallography. If you don’t already know, metallography is a type of scientific microimaging that involves mirror-polishing metal surfaces and then etching them with various reagents […]

In this clip from FMCG, Ken responds to Jeri’s capacitor deconstruction with his own very visual (and very mechanical) demonstration of how voltage is generated and how you can build a simple capacitor, with aluminum foil and plastic, to generate charge mechanically and dump it into the cap (analogous to how a Wimshurst machine works). […]
Our pal Jeri Ellsworth and her crew of restless USTREAM-ing hackers are at it again, exploring light polarization, sparking ions, and reversing time. The Fat Man and Circuit Girl
I recently got it in my head that I wanted to take some time-lapse photos showing the oxidation of various bright-polished metals over the course of a week or so. Investigating the possibility of setting up an intervalometer for my elderly Coolpix 4300 quickly became frustrating, however, as I realized that I was facing a […]
William Grill needed a better view of his work surface for project prototyping. Using an inexpensive color video camera, he was able to create a simple display system that shows his work at 12x on his PC monitor. “It’s amazing what detail you can see when you view your solder surface mounted parts at 7-, […]
