We know you’ve seen them: the time-lapses that show a 3D print coming together layer-by-layer without the extruder taking up half the frame. It takes a little extra work compared to just pointing a camera at the build plate, but it’s worth it to see your prints materialize like magic. Usually these are done with […]
[JesseDarr] recently wrote in to tell us about their dynamic Arm for Robitc Mischief (dARM), a mostly 3D printed six degrees of freedom (6DOF) robotic arm that’s designed to be stronger and more capable than what we’ve seen so far from the DIY community. The secret? Rather than using servos, dARM uses brushless DC (BLDC) […]
Should you travel around Europe, you may notice that things in France are ever so slightly different. Not necessarily better or worse, simply that the French prefer to plough their own furrow rather than importing cultural tends from their neighbors. In the 1980s this was evident in their home computers, because as well as a […]
We’ve seen tons of projects lately using the ESP32-C3, and for good reason. The microcontroller has a lot to offer, and the current crop of tiny dev boards sporting it make adding a lot of compute power to even the smallest projects dead easy. Not so nice, though, is the poor WiFi performance of some […]
The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock that’s hard to access, they’ll all adjust themselves as necessary to keep perfect time. But what if the […]
We’ve got a love-hate relationship with discount tool outlet Harbor Freight: we hate that we love it so much. Apparently, [James Clough] is of much the same opinion, at least now that he’s looked into the quality of their outlet strips and found it somewhat wanting. The outlet strips in question are Harbor Freight’s four-foot-long, twelve-outlet […]
Afficionados of vintage electric organs will know about the Melotron, an instrument from the 1960s that had pre-recorded sounds on a bank of tape loops. A real Melotron in working order will set you back a bit, but it’s possible to play with the idea using much more attainable hardware. [Decurus] has made a simple […]
Yeah, yeah — not a keyboard. But one keyboard-adjacent topic I’m certainly interested in is that of finding a satisfying mouse. Why settle for ticky micro-switches when you could have full-on thock in both peripherals? My own personal peripherals. Banana mat for scale. I’ve been using a Logitech Ergo M575 for a couple of years […]
While low-cost professional PCB fabrication has largely supplanted making circuit boards at home, there’s still something to be said for being able to go from design to prototype in an afternoon. Luckily we aren’t limited to the old toner transfer trick for DIY boards these days, as CNC routers and powerful lasers can be used […]
Over the history of the Web, we have seen several major shifts in browsing software. If you’re old enough to have used NCSA Mosaic or any of the other early browsers, you probably welcomed the arrival of Netscape Navigator, and rued its decline in the face of Internet Explorer. As Mozilla and then Firefox rose […]
