The Free Software Foundation is holding an auction to celebrate its 40th anniversary. You can bid on the original sketch of the GNU head by [Etienne Suvasa] and [Richard Stallman’s] Internet Hall of Fame medal. There are some other awards, including the FSF’s 1999 Norbert Wiener Award. There’s even a katana that symbolizes the fight […]
A significant event in the world of high-power electrical engineering is under way this weekend, as the three Baltic states, Lithuania, Latvia, and Estonia, disconnect their common power grid from the Russian system, and hook it up to the European one. It’s a move replete with geopolitical significance, but it’s fascinating from our point of […]
Prolific woodworking YouTuber [Matthias Wandel] makes some awesome mechanical contraptions, and isn’t afraid of computers, but has never been a fan of CNC machines in the woodshop.

Like many pieces of lab equipment, oscilloscopes are both extremely useful and rather intimidating to a fledgling user. Unlike a digital multimeter with its point-and-measure functionality, digital storage oscilloscopes (DSOs) require fundamental knowledge before they can be used properly. Yet at the same time nobody likes reading manuals, so what is one to do? Try […]
It seems obvious once you think about it, but if you can spin your cell phone and coordinate the display with the motion, you can create a 3D display. [Action Lab] had used such a setup to make a display that you could view from any angle. After he showed it, a viewer wrote him […]
When you see a ventriloquist like [Jeff Dunham], you probably expect to see him with a puppet. This time – spoilers ahead – you won’t. Besides his fame on stage, [Dunham] is also a collector of vintage tech and a die-hard television enthusiast. In the video below, [Dunham] has gotten his hands on a rarity: […]
