    Sexiest Tiny Metal Core-XY 3D Printer | Hackaday

    hackaday.com 27 Apr '17, 8am

    That’s a lot of qualifications, but we’re pretty sure that you can’t accuse us of hyperbole in the title: this is one of the tightest little 3D printer builds we’ve ever seen . Add in the slightly esoteric CoreXY kinematics and the thick aluminum frame, and it’s a speed demon in addit...

    hackaday.com 27 Apr '17, 5am

    Hands up if you feel your spiritual home is in front of a terminal with a “DIGITAL” logo on it. It’s a name that has long ago been subsumed into first Compaq and then by extension HP, but it’s one with a lot of history when it comes to computing. From the start of the electronic compu...

  • FPGAs in C with Cynth | Hackaday

    hackaday.com 27 Apr '17, 2am

    Programming an FPGA with Verilog looks a lot like programming. But it isn’t, at least not in the traditional sense. There have been several systems that aim to take C code and convert it into a hardware description language. One of these, cynth , is simple to use and available on GitH...

    Do your Mark 1 Eyeballs no longer hold their own when it comes to fine work close up? Soldering can be a literal pain under such conditions, and even for the Elf-eyed among us, dealing with pads at a 0.4-mm pitch is probably best tackled with a little optical assistance. When the time...

  • Old Part Day: Voltage Controlled Filters | Hackaday

    hackaday.com 26 Apr '17, 5am

    For thirty years, the classic synths of the late 70s and early 80s could not be reproduced. Part of the reason for this is market forces — the synth heads of the 80s didn’t want last year’s gear. The other part for the impossibility to build new versions of these synths was the lack o...

    hackaday.com 25 Apr '17, 8pm

  • Ask Hackaday: What About the Diffusers? | Hackaday

    hackaday.com 25 Apr '17, 5pm

    I’ve mastered the “hackery” diffusers. You can make pretty good indicator light from 5mm LED if you lop off the dome, sand that cut until it looks frosty, then use a panel-mount LED grommet (a little black plastic ring that these LEDs snap into). I’ve done the hot-glue thing but that ...

    hackaday.com 25 Apr '17, 11am

    It makes sense considering evolution, but nature comes up with lots of different ways to do things. Consider moving. Land animals walk on four feet or two, some jump, and some use peristalsis or otherwise slither. Oddly, though, mother nature never developed the wheel (although the mo...

    hackaday.com 25 Apr '17, 5am

    The ESP32 is Espressif’s new wonder-chip, and one of the most interesting aspects of its development has been the almost entirely open-source development strategy that they’re taking. But the “almost” in almost entirely open is important — there are still some binary blobs in the syst...

  • Hackaday Prize Entry: MCXY – Mini Laser Cut Aluminum 3D Printer | Hackaday

    hackaday.com 25 Apr '17, 2am

    Box design printers at that size have one major drawback for me: Accessibility to the hot end for maintenance. For an “Ultimaker sized” printer, the box design can still work, because you can move the bed out of the way and gain access to unclog/clean/swap your nozzle without too much...
