While it would have been considered science-fiction just a few decades ago, the ability to watch virtually any movie or TV show on a little slab that fits in your pocket is today no big deal. But for an electronics beginner, being able to put together a pocketable video player like this one would be quite exciting, […]

We have all encountered bill acceptors like the one [Another Maker] recently removed from an arcade machine and sometimes struggled with them. Have you ever disassembled one to observe its functioning? If not, the video following this is an intriguing look at how this common device distinguishes between a genuine bill and a sheet of

How many of us have an everyday tool that’s truly unique? Likely not many of us; take a look around your desk and turn out your pockets, but more often than not, what you’ll find is that everything you have is something that pretty much everyone else on the planet could have bought too. But

The Internet of Things (IoT) as a concept is not new, but while our phones and our televisions got smarter over the last few years, our homes haven’t changed as much. There are now a growing number of IoT startups in India, such as connected-car accessory-make CarIQ, and smart-bulb maker Cube26, but does using such devices actually
Adafruit has announced a new entry in its Metro line of Arduino UNO form factor microcontroller development boards, and this time it’s playing host to a Raspberry Pi RP2040 dual-core Arm Cortex-M0+ chip — and it’s called, unsurprisingly, the Adafruit Metro RP2040. “This is the RP2040 Metro Line, making all station stops at ‘Dual Cortex
A cozy night in with a hardware capture-the-flag challenge, embedded in a gorgeous PCB conference badge! This year, I had the pleasure of interviewing Abhinav Pandagale about his full-color PCB badges for this year’s RSA Conference and BSides SF security events in San Francisco. He showed me some cool demos and info about the UV printing used on both badges: Abhinav

There’s nothing fun about a Sisyphean task unless you’re watching one being carried out by someone or something else. In that case, it can be mesmerizing like this Arduino-driven kinetic sand table. Like many of these builds, it all started with an ordinary coffee table from the hacker’s favorite furnitüre store. [NewsonsElectronics] opened it up and

[Mark aka Mokey] borrowed his friend’s open-frame laser engraver for a while, and found it somewhat lacking in features and a bit too pricey for what it was. Naturally, he thought he could do better (video, embedded below.) After a spot of modelling in Fusion 360, and some online shopping at the usual places, he had all

You don’t have two ears by accident. [Stoppi] has a great post about this, along with a video you can see below. (The text is in German, but that’s what translation is for.) The point to having two ears is that you receive audio information from slightly different angles and distances in each ear and your
