Power is supplied by a USB-A cable with the data wires cut off, with a switch controlling the voltage and a rectifier diode protecting the USB port or battery pack from back voltage from the motor.

The drill isn’t very powerful, only able to bore holes in PCBs, plastic, and similar soft materials. However, you could see how just a couple more components could make it even more robust — maybe a speed controller and voltage booster? Even so, …read more http://pje.fyi/Pr3CLd

Hackaday Prize Entry: USB Packet Snooping

Sometimes you run into a few problems when developing your own hardware, and to solve these problems you have to build your own tools. This is exactly how [KC Lee]’s USB Packet Snooper was created. It’s a small device that allows for capturing and analyzing Full Speed USB traffic to debug one of [KC]’s other Hackaday Prize entries.

[KC] is building an HID Multimedia Dial for this year’s Hackaday Prize. It’s kind of like the Microsoft Surface Dial or the ubiquitous Griffin PowerMate that has been on the market for the better part of two decades. This multimedia dial is …read more http://pje.fyi/PZQhtf
