Once upon a time, lathes were big heavy machines driven by massive AC motors, hewn out of cast iron and sheer will. Today, we have machine tools of all shapes and sizes, many of which are compact and tidy DIY creations. [Maxim Kachurovskiy]’s Modulathe fits the latter description nicely. The concept behind the project was […]
The RP2040 has quickly become a hot favorite with tinkerers and makers since its release in early 2021. This is largely attributed to the low cost, fast GPIOs, and plethora of bus peripherals. [xyphro] has written the I3C Blaster firmware that helps turn the Raspberry Pi Pico into a USB to I3C converter. The firmware […]
[Surya Chilukuri] writes in to share JTAGprobe — a fork of the official Raspberry Pi debugprobe firmware that lets you use the low-cost microcontroller development board for JTAG and SWD debugging just by flashing the provided firmware image. We’ve seen similar projects in the past, but they’ve required some additional code running on the computer […]
If you needed to weld something in a pinch, what’s the minimum complement of equipment you could get away with? In [Professor Bardal]’s case, it’s a couple of motorcycle batteries and a roll of flux-core wire, and not much else. We suspect this one is going to elicit quite a few comments, not least by […]
Sometimes it’s the simplest hacks that make the biggest impact. Take these DIY magnetic PCB vises for example. Sure, you can go out and buy purpose-built tools, but [Dylan Radcliffe] just made a trip to the hardware store for some nuts and bolts. He chose 3/8″-16 bolts, which would probably be around M10 for the […]
As a general concept, fault injection is a technique that studies how a system reacts to unusual or unexpected external forces. The idea is that, if you can trigger a glitch at the precise moment, you might be able to use that to your advantage in disabling security features or otherwise gaining further access to […]
When we reviewed the iFixit FixHub back in September, one of the most interesting features of the portable soldering station was the command line interface that both the iron and the base station offered up once you connected to them via USB. While this feature wasn’t documented anywhere, it made a degree of a sense, […]
For a lot of us, soldering just seems to come naturally. But if we’re being honest, none of us was born with a soldering iron in our hand — ouch! — and if we’re good at soldering now, it’s only thanks to good habits and long practice. But what if you’re a company that lives […]
At this point, many of us have gone all-in on USB-C. It’s gotten to the point that when you occasionally run across a gadget that doesn’t support being powered USB-C, the whole experience seems somewhat ridiculous. If 90% of your devices using the same power supply, that last 10% starts feeling very antiquated. So why […]
