It’s one thing to create your own relay-based computer; that’s already impressive enough, but what really makes [DiPDoT]’s design special– at least after this latest video— is swapping the SRAM he had been using for historically-plausible capacitor-based memory. A relay-based computer is really a 1940s type of design. There are various memory types that would […]
Most end tables that you might find in a home are relatively static objects. However, [Peter Waldraff] of Tiny World Studios likes to build furniture that’s a little more interesting. Thus came about this beautiful piece with a real working railway built right in. The end table was built from scratch, with [Peter] going through […]

The cable traversed the Sea of Okhotsk, which, at the time, the USSR claimed. It was off limits to foreign vessels, heavily patrolled, and laced with detection devices. How much more secure […]
There’s just something delightful about scaled items. Big things shrunk down, like LEGO’s teeny tiny terminal brick? Delightful. Taking that terminal brick and scaling it back to a full-sized computer? Even better. That’s what designer [Paul Staal] has done with his M2x2 project. In spite of the name, it actually has a Mac Mini M4 […]
Elastocaloric materials are a class of materials that exhibit a big change in temperature when exposed to mechanical stress. This could potentially make them useful as solid-state replacement for both vapor-compression refrigeration systems and Peltier coolers. The entire assembled elastocaloric device. (Credit: Guoan Zhou, Nature, 2026) So far one issue has been that reaching freezing […]
Guitar pedals are designed to take in a sound signal, do fun stuff to it, and then spit it out to your amplifier where it hopefully impresses other people. However, [Liam Taylor] decided to see what would happen if you fed video through a guitar pedal instead. The device under test is a Boss ME-50 […]
