Over on his blog our hacker [Scott Baker] has a Magnetic Bubble Memory Mega-Post. If you haven’t heard of magnetic bubble memory before it’s basically obsolete nonvolatile memory. Since…

For something non-explosive, this might be the most American project we’ve featured in a while. [Makerinator]’s domestic bliss was apparently threatened by the question “what shal…

Ever tear open a potentiometer? If you haven’t, you can still probably guess what’s inside. A streak of resistive material with some kind of contact that moves across it as you rotate t…

Designer furniture generally comes with excellent aesthetics and (sometimes) functionality. However, such furniture comes with a price to match. One such piece of furniture is the Magis Spun Chair.…

We like to think that we can do almost anything. Give me a broken piece of consumer electronics, and I’ll open it up and kick the capacitors. Give me an embedded Linux machine, and I’ll poke around…

When making a personal website, one will naturally include a personal touch. What could be more personal than creating a font from your own handwriting? That’s what [Chris Smith] has done, an…

Weekends can be busy for a lot of us, but sometimes you have one gloriously free and full of possibilities. If that’s you, you might consider taking a gander at [Peter Shirley]’s e-book…

Do you or a loved one suffer from distorted 3D prints? Does your laser cutter produce parallelograms instead of rectangles? If so, you might be suffering from CNC skew miscalibration, and you could…

Your kid has a toy remote control fire truck. You have an RTL SDR. See where this is going? [Jacob] couldn’t resist tearing into the why and how of the truck’s remote control protocol. …

People think about NiMH cell chargers probably as much as they think about batteries, unless it’s time to replace the cells in whatever device they’re installed in. This doesn’t m…

Wireless earbuds are notoriously tiny. Want to see inside? [MCH170] did and published a Soundcore Space A40 Teardown. In this teardown, you’ll see inside the charging case and one of the earb…

Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at [aritrakdebnath2003]’s MIDI THEREMIN, we see it works differently, but it do…

Much of the expense of developing AI models, and much of the recent backlash to said models, stems from the massive amount of power they tend to consume. If you’re willing to sacrifice some ability…

Aside from a few stand-out programs — looking at you, Star Trek — by the late 1960s, TV had already become the “vast wasteland” predicted almost a decade earlier by Newton M…

Immersive audio is the new hotness in the recording world. Once upon a time, mono was good enough. Then someone realized humans have two ears, and everyone wanted stereo. For most of us, that&#8217…

Two weeks ago, it was holographic cops. This week, it’s humanoid robot doctors. Or is it? We’re pretty sure it’s not, as MediBot, supposedly a $10,000 medical robot from Tesla, ap…

Bambu Labs make indisputably excellent printers. However, that excellence comes at the cost of freedom. After a firmware release earlier this year, Bambu printers could only work with Bambu’s…

These days, most of us have a smartphone. They are so commonplace that we rarely stop to consider how amazing they truly are. The open-source project Phyphox has provided easy access to your phone’…

The rotary evaporator (rotovap) rarely appears outside of well-provisioned chemistry labs. That means that despite being a fundamentally simple device, their cost generally puts them out of reach f…

The 1993 Pioneer LaserActive certainly ranks high on the list of obscure video games. It was an odd duck; it used both a LaserDisc for data storage and provided compatibility with a range of existi…
