If you’re like us, the oscilloscope on your bench is nothing special. The lower end of the market is filled with cheap but capable scopes that get the job done, as long as the job doesn’t get too far up the spectrum. That’s where fancier scopes with active probes might be required, and such things are budget-busters for mere mortals. Then again, something...
In the world of lambda calculus programming languages there are many ways to express the terms, which is why we ended up with such an amazing range of programming languages, even if most trace their roots back to ALGOL. Of the more unique (and practical) languages, Lisp and Forth probably range near the top, but what if you were to smudge both together?...

The Marimbatron is [Leo Kuipers] ‘s final project as part of the MIT “Fabacademy program” supervised by [Prof. Neil Gershenfeld] of the Center for Bits and Atoms. The course aims to learn how to leverage all the fab lab skills to create unique prototypes using the materials at hand. The final polyurethane/PET/Flex PCB stack-up for the sensor pad Fortunately,...
The entertainment systems in modern vehicles is akin to a small in-dash computer, and handles all manner of digital content. It probably also incorporates a radio, but increasingly that’s treated as something of an afterthought. There was a time though when any radio in a car was a big deal, and if you own a car from that era it’s possible that you’ve...
There are a lot of oscilloscopes from around the 1990s which are still very much desirable today, such as the Tektronix TDS 744A which [DiodesGoneWild] got his grubby mitts on. This is a 500 MHz, 4-channel scope, with a capture rate of 500 MS/s (4 channels) to 2 GS/s (1 channel). It also has a color display and even comes with a high-density (1.44 MB)...
