After initially working to create a modernized replica of a Czechoslovakian 4-digit Metra M1T242 voltmeter, [Jaromir Sukuba] figured that while he was at it, he might as well create a voltmeter that would be slightly more capable.

While fiber can be produced for a better price than copper wire equivalents, they’re still not easy or cheap to manufacture. Silica fibers require spinning tubes on a lathe, which requires the fiber’s core to be precisely centered. […]

What was originally developed in 1969 as a lighter weight timesharing system for a DEC minicomputer at Bell Labs has exerted a huge influence over […]
Taking a page out of the Xzibit Engineering Handbook, [Geeksmithing] recently decided that the gutted carcass of an original Nintendo Entertainment System would make a perfect home for…a smaller NES. Well, that and two wireless controllers. Plus a projector. Oh, and batteries so it can be used on the go. Because really, at that point, […]
Some people love fan noise, using it to help get to sleep or just create some ambience in a room. Others hate it, like [Dmitri], and will take severe measures to eliminate it where possible. When his Razer Blade laptop was incessantly whirring away, it was time to get to work. The Razer laptop uses […]
Retroreflectors are interesting materials, so known for their nature of reflecting light back to its source. Examples include street signs, bicycle reflectors, and cat’s eyes, which so hauntingly pierce the night. They’re also used in the Tilt Five tabletop AR system, for holographic gaming.
