Jeff Geerling ☛ Sipeed NanoKVM: A RISC-V stick-on
This is the Sipeed NanoKVM. You stick it on your computer, plug in HDMI, USB, and the power button, and you get full remote control over the network—even if your computer locks up.
How did Sipeed make it so small, and so cheap? The 'full' kit above is about $50, while the cheapest competitors running PiKVM are closer to $200 and up!

Hackaday ☛ Fixing An Elgato HD60 S HDMI Capture Device
There’s a special kind of satisfaction found in the act of repairing a previously broken device, which is why YouTube is full of repair channels and guides on how to do it yourself. Inspired by this, [Doug Brown] decided to give it a shot himself, with an Elgato HD60 S HDMI capture device as the patient. As per the eBay listing, the device did not show up as a USB device when connected to a computer — a quick probing of the innards revealed that not only were the board voltages being dragged down, but some of the components on the PCB were getting suspiciously hot.

Arduino ☛ Transform trash into treasure with the DIY Bottle Plotter
The Bottle Plotter is relatively affordable to build, as most of the parts are 3D-printable. The exceptions are fasteners, bearings, rods, and the electronic components. Those electronics include an Arduino UNO Rev3 board, a CNC shield, and stepper motors. VGaman’s design does include a Z axis (to move the pen closer to and further from the workpiece surface), so the machine requires three stepper motors.
