  • Hackaday Prize Entry: A Cluster Of Exoskeletons | Hackaday

    hackaday.com 26 Oct '16, 5am

    The current trend of 3D printed prosthetic hands have one rather large drawback: you can’t use them if you already have two hands. This might seem like a glib objection, but one of last week’s Hackaday Prize posts pointed this out rather well – sometimes a meat machine needs mechanica...

    Dual-boot Your Arduino | Hackaday

    hackaday.com 25 Oct '16, 6pm

    There was a time, not so long ago, when all the cool kids were dual-booting their computers: one side running Linux for hacking and another running Windows for gaming. We know, we were there. But why the heck would you ever want to dual-boot an Arduino ? We’re still scratching our hea...

    Sailing Ships, Slide Rules, and the Quality of Engineering | Hackaday

    hackaday.com 25 Oct '16, 5pm

    We recently ran a post about engineers being worse, better, or the same than they “used to be” and it got me thinking. Of course “used to be” is in the eyes of the beholders. To me, that’s the 1950s and 1960s. To some of you, my generation is the “used to be” generation. To some of yo...

  • Death To The 3.5mm Audio Jack, Long Live Wireless | Hackaday

    hackaday.com 25 Oct '16, 2pm

    I don’t know why this of all articles I’ve read on Hackaday prompted me to stop lurking and comment, but I think it’s because many of the responses to this article are as emotional and reductive in their defense of the audio jack as they claim the author is in his argument against it....

    Raspberry Pi Zero as a USB Stick | Hackaday
