[Max K] has been testing the battery life of his self-designed watch under real-world conditions. Six months later, the nominally 3 V, 160 mAh CR2025 cell is reading 2.85 V, so the end is near, but…

Whenever I end up with a new vehicle I ultimately end up sticking in a new GPS/Receiver combination for better sound quality and a better GPS. I am quite at home tearing into a dashboard as I was l…

Researchers from VUSec found a way to break ASLR via an MMU sidechannel attack that even works in JavaScript. Does this matter? Yes, it matters. A lot. The discovery of this security flaw along with...

Way back in the before years when there were still interesting concepts for reality TV, Nate Seidle blew up a power supply in his dorm room. Instead of finding replacement parts, Nate decided to star...

We’ve seen a lot of interest in LSM (LASER Scanning Microscopes) lately. [Stoppi71] uses an Arduino, a CD drive, and–of all things–two speakers in his build. The speakers are used…

We don’t think [VK4FFAB] did himself a favor by calling his seven-part LTSpice tutorial LTSpice for Radio Amateurs. Sure, the posts do focus on radio frequency analysis, but these days lots o…

There used to be a time, before running shoes had blinking LEDs and required placing on an inductive charger overnight, when we weren’t worried about whether or not we could dump the firmware…

Here's a slick-looking VGA demo written in assembly by [Yianni Kostaris]; it's VGA output from an otherwise stock ATmega2560 at 16MHz with no external chips involved. If you're getting some Super Ma...

What I particularly like about the Van de Graaff (or VDG) is that it’s a combination of a few discrete scientific principles and some mechanically produced current, making it an interesting s…

No one can deny what SpaceX and Blue Origin are doing is a feat of technological wizardry. Building a rocket that takes off vertically, goes into space, and lands back on the pad is an astonishing …

3D printers are an exercise in compromise. Generally, you don't want a lot of mass on your tool head, as that can lead to ringing and other mechanical artifacts on your print. However, direct drive ex...

MakerBot CEO [Nadav Goshen] announced that changes are needed to ensure product innovation and support long-term goals in a blog post published yesterday. To that end, MakerBot will reduce its staff...

A little MDF, a little plywood, some bits of threaded rod - put it all together and you've got this low-cost desktop CNC build using very few parts you'd need to go farther afield than the local hom...

Vacuum formers are useful tools to have around the shop and also an incredibly simple technology. All you need is a plastic sheet, a heater of some kind, a table with a bunch of holes in it, and a vac...

From the blog of [telmomoya] we found his latest project: a hardware based multicore solution for a ZX Spectrum Emulator. It’s not the first time we feature one of his builds, last year we wa…

A while back, [limpfish] bought a few four-digit seven-segment displays from a seller on eBay. A month or two later, thirty displays ended up in [limpfish]’s mailbox. Instead of using the one…

If you were a child of the late 1980s or early 1990s, the chances are you’ll be in either the Super Nintendo or the Sega Genesis/Mega Drive camp. Other 16-bit games consoles existed, but thes…

I had a friend who was an engineer for a small TV station. I visited him at work once, and despite the fact that he wouldn’t let me climb the 1,200′ antenna tower, I had a great time. I…

Exploiting the flexibility of plastic, a group of researchers has created a 3D printable microscope with sub-micron accuracy. By bending the supports of the microscope stage, they can manipulate a sam...

The LTC4316 is something special. It’s an I²C address translator that changes the address of a device that would otherwise conflict with another on the same I²C bus. Not a hack? Not so fast. …
