Of the popular 1980s 8-bit computers, it’s fair to say that Sinclair’s ZX Spectrum punched above its weight. Sir Clive’s love ...

Much of science is performed through inference, with the readings on instruments, a flash of light in heavy water, or the ...

As cool as it would have been to wield lasers that produce a beam of neutrinos, recently two papers were published by MIT researchers that seem to dampen the likelihood of such lasers being at all ...

Here in 2026 if we need a terminal the chances are we fire one up on our computer and continue on our way without a thought. What we are doing of course is emulating the experience of earlier ...

Stepper motors are undeniably useful, but sometimes they need a bit of gearing to help perform their task. [Gjhudson2008] has a compact gearbox for NEMA 17 or 23 steppers that is mostly 3D printed.

You’ve probably heard of rubidium frequency standards, which are used where you need an extremely accurate time or frequency reference. [IMSAI] guy has a good explainer video about what’s actually ...

We all have that bin in the corner of our shops — the one with all the circuit boards or broken electronics that we are totally gonna do something with. We might rationalize that they’re worth keeping ...

[ArduinoNmore] took an interesting approach to designing a counter intended to accurately display how many meters of filament a 3D printer has used. The Filamentmeter looks a little bit like a 3D ...

The average 3D printer owner knows a few types of filaments – PLA, ABS, somewhere in the middle, PETG. PCTG is another option that can be confusingly similar to PETG. Recently, [Igor Gaspar] of [My ...

In general, you get what you pay for, and when [Craig] picked up a cheap function generator off eBay, he didn’t expect much from it. But as he shows us in his blog post and a series of videos below, ...

[Adafruit]’s Voicebox FX gadget is a fun, well-documented project that serves another useful purpose: being a fantastic reference design for audio on CircuitPython, with I 2 S audio components. Be ...

Although some would argue that the hexagon is the bestagon, astronomers have discovered that Saturn appears to favor the ten-sided decagon on its south pole. This comes as its south pole has recently ...
