Stripping and cutting wires can be a tedious and repetitive part of your project. To save time in this regard, [Red] built an automatic stripper and cutter to do the tiring work for him. An ESP32 runs the show in this build. Via a set of A4988 stepper motor drivers, it controls two NEMA 17 […]
There are plenty of audio mixers on the market, and the vast majority all look the same. If you wanted something different, or just a nice learning experience, you could craft your own instead. That’s precisely what [Something Physical] did.  The build was inspired by an earlier 3-channel mixer designed by [Moritz Klein]. This project […]
When you think of open-source hardware, you probably think of electronics and maker tools– RepRap, Arduino, Adafruit, et cetera. Yet open source is an ethos and license, and is in no way limited to electronics. The openmovement foundation is a case in point– a watch case, to be specific. The “movement” in Openmovement is a […]
Few of us will ever find ourselves piloting a full-sized military tank. Instead, you might like to make do with the RC variety. [TRDB] has whipped up one of their own design which features a small little pellet cannon to boot. The tank is assembled from 3D printed components — with PETG filament being used […]
You turn the dial on your radio, and hear a powerful source of interference crackle in over the baseline noise. You’re interested as to where it might be coming from. You’re receiving it well, and the signal strength is strong, but is that because it’s close or just particularly powerful? What could it be? How […]
[Leo Goldstien] recently got in touch to let us know about a fascinating update he posted on the Hackaday.io page for ManiPylator — his 3D printed Six degrees of freedom, or 6DOF robotic arm. This latest installment gives us a glimpse at what’s involved for command and control of such a device, as what goes […]
Growing up as a kid in the 1990s was an almost magical time. We had the best game consoles, increasingly faster computers at a pace not seen before, the rise of the Internet and World Wide Web, as well the best fashion and styles possible between neon and pastel colors, translucent plastic and also this […]
Adding textures is a great way to experiment with giving 3D prints a different look, and [PandaN] shows off a method of adding a wood grain effect in a way that’s easy to play around with. It involves using a 3D model of a log (complete with concentric tree rings) as a print modifier. The […]
For most of us, mirrors are something we buy instead of build. However, [Unnecessary Automation] wanted to craft mirrors of his own for a custom telescope build. As it turns out, producing optically-useful mirrors is not exactly easy. For the telescope build in question, [Unnecessary Automation] needed a concave mirror. Trying to get that sort […]
For those of us who’ve spent far too long hammering rubber keys into submission, a glorious solution has arrived. [Lee Smith] designed the ZX Mechtrum Deluxe, the ultimate keyboard upgrade for your beloved ZX Spectrum 48k. Thanks to [morefunmakingit], you can see this build-it-yourself mechanical mod below. It finally brings a proper spacebar and Spectrum-themed […]
