The age of cheap and powerful devices is upon us. How about a 20 EUR handheld game console intended for retro game emulation, that runs Linux under the hood? [Luiz Ferreira] kicks the tires of a R36S, a very popular and often cloned device running a quad-core RK3326 with an Ubuntu-based OS, and shows us […]
The Dutch word for sundial, zonnewijzer, can be literally translated into “Sun Pointer” according to [illusionmanager] — and he took that literal translation literally, building a reverse sundial so he would always know the precise location of our local star, even when it is occluded by clouds or the rest of the planet. The electronics […]
For as long as there have been supercomputers, people like us have seen the announcements and said, “Boy! I’d love to get some time on that computer.” But now that most of us have computers and phones that greatly outpace a Cray 2, what are we doing with them? Of course, a supercomputer today is […]
There’s a type of dust-collector that’s been popular since the 1990s, where a cube of acrylic or glass is laser-etched in a three-dimensional pattern. Some people call them bubblegrams.

For less than $30 USD, you can get a 10×10 centimeter hotplate with 350 Watts of power. Sounds mighty fine to us, so surely there must be a catch? Maybe not, as [Stefan Nikolaj]’s review of this AliExpress hotplate details, it seems to be just fine enough. At this price, you’d expect some shoddy electronics […]
The “Long Dark” is upon us, at least for those who live north of the equator, and while it’s all pre-holiday bustle, pretty lights, and the magical first snow of the season now, soon the harsh reality of slushy feet, filthy cars, and not seeing the sun for weeks on end will set in. And […]
Back in March, a small aircraft in the UK lost engine power while coming in for a landing and crashed. The aircraft was a total loss, but thankfully, the pilot suffered only minor injuries.
