It’s a common enough problem: you’re hitting the books, your phone dings with a notification, and suddenly it’s three hours later. While you’ve done lots of scrolling, you didn’t do any studying. If only there were a quick, easy project that would keep an eye on you and provide a subtle nudge to get you […]
With the newer generation of quick and reliable 3D printers, we find ourselves with the old collecting dust and cobwebs. You might pull it out for an emergency print, that is if it still works… In the scenario of an eternally resting printer (or ones not worth reviving), trying to give new life to the […]
After having been involved in an accident, [Kurt Kohlstedt] suffered peripheral neuropathy due to severe damage to his right brachial plexus — the network of nerves that ultimately control the shoulder, arm, and hand. This resulted in numbness and paralysis in his right shoulder and arm, with the prognosis being a partial recovery at best. […]
The advent of cheap and accessible one-off PCB production has been one of the pivotal moments for electronic experimenters during the last couple of decades. Perhaps a few still etch their own boards, but many hobbiest were happy to put away their ferric chloride. There’s another way to make PCBs, though, which is to mill […]
Both small children and cats have a certain tendency to make loud noises at inopportune times, but what if there were a way to combine these auditory effects? This seems to have been the reasoning behind the creation of the Meowsic keyboard, a children’s keyboard that renders notes as cats’ meows. [Steve Gilissen], an appreciator […]
We’ve all been there. [Kasyan TV] had a universal adapter for a used laptop, and though it worked for a long time, it finally failed. Can it be fixed? Of course, it can, but it is up to you if it is worth it or not. You can find [Kasyan’s] teardown and repair in the […]
If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, easy-to-implement circuit. Most multimeters have a diode test function that can be used to check LEDs; however, this goes a step further. Not […]
The Francis! Francis! X1 espresso machine in its assembled state. (Credit: Samuel Leeuwenburg) Recently, [Samuel Leeuwenburg] got his paws on a Francis! Francis! X1 (yes, that’s the name) espresso machine. This is the espresso machine that is mostly famous for having been in a lot of big TV shows in the 1990s. In the early […]
The intersection between “woodworkers” and “programmers” is not a densely populated part of the Venn diagram, but [Michael Schiebler] is there with his Kerf Bend Wizard to help us make wood twist and bend like magic. Kerf bending is a fine technique we have covered before: by cutting away material on the inside face of […]
The Switch 2 Pro controller’s battery is technically removable, if you can get to it. (Credit: VK’s Channel, YouTube) For those of us who have worked on SNES and GameCube controllers, we know that these are pretty simple to get into and maintain. However, in the trend of making modern game controllers more complex and […]
