Paul Stoffregen did it again: the Teensy 4.0 has been released. The latest in the Teensy microcontroller development board line, the 4.0 returns to the smaller form-factor last seen with the 3.2, as opposed to the larger 3.5 and 3.6 boards. Don’t let the smaller size fool you; the 4.0 is based on an ARM […]
At the top of the British electronic intelligence agency is the Government Communications Headquarters (GCHQ), a very public entity whose circular building can easily be found by any inquisitive soul prepared to drive just off the A40 in Cheltenham which is about two hours west of London. But due to the nature of its work […]
Your run-of-the-mill desktop 3D printer is based on a technology known as Fused Deposition Modeling (FDM), where the machine squirts out layers of hot plastic that stick to each other. But that’s not the only way to print a Benchy. One of the more exotic alternative techniques uses a photosensitive resin that gets hardened layer […]
The newest offering from the AND!XOR team is out and it delivered exactly what hardware badges were missing: light pipes. No joke, the DEF CON 27 edition AND!XOR badge will be most recognizable because of two arcs of light pipe material blinging RGB goodness in three dimensions. But if you can peel your eyes away […]

Readers with long memories will recall there was a time when I amused myself by tacking inexpensive tools or electronic devices to my various orders from the Chinese electronic Aladdin’s Cave. Often these inexpensive purchases proved to be as disastrous or […]
Several months ago, a strange Kickstarter project from ‘Team IoT’ appeared that seemed too good to be true. The Atomic Pi was billed as a high-power alternative to the Raspberry Pi, and the specs are amazing. For thirty five American buckaroos, you get a single board computer with an Intel processor. You get 16 Gigs […]
When I am at a loss for an explanation in the world of electronics, I reach for my well-thumbed Horowitz & Hill. When H&H fails me which is not that often, the chances are I’ll find myself looking in an application note from a semiconductor company who is in cut-throat competition with its rivals in […]
[VoltLog] got a hold of a prerelease unit of Joulescope — a DC energy analyzer that promises to make it easy to optimize power and energy usage of your electronic designs. You can find his review in the video below. The device is a very fast ammeter and voltmeter. Given that, it is easy to […]
When you go to a hacker conference, you always hope there’s going to be a hardware badge. This is an interactive piece of custom electronics that gets you in the door while also delighting and entertaining during the con (and hopefully far beyond it). Hot off the presses then is the Hacker Hotel badge, from […]
