Let me throw in a curveball—watching your 3D print fail in real-time is so much more satisfying when you have a crisp, up-close view of the nozzle drama. That’s exactly what [Mellow Labs] delivers in his latest DIY video: transforming a generic HD endoscope camera into a purpose-built nozzle cam for the Prusa Mini. The […]

It’s the podcast so nice we recorded it twice! Despite some technical difficulties (note to self: press the record button significantly before recording the outro), Elliot and Dan were able to soldier through our rundown of the week’s top hacks. We kicked things off with a roundup of virtual keyboards for the alternate reality crowd, […]
While the COVID-19 pandemic wasn’t an experience anyone wants to repeat, infections disease experts like [Dr. Pardis Sabeti] are looking at what we can do to prepare for the next one.

It’s a group of […]
Imagine a bare-bones electric pickup: it’s the size of an old Hilux, it seats two, and the bed fits a full sheet of plywood. Too good to be true? Wait until you hear that the Slate Pickup is being designed for DIY repairability and modification, and will sell for only $20,000 USD, after American federal […]
We all appreciate clear easy-to-read reference materials. In that pursuit [Andreas] over at Splitbrain sent in his latest project, Pinoutleaf. This useful web app simplifies the creation of clean, professional board pinout reference images. The app uses YAML or JSON configuration files to define the board, including photos for the front and back, the number […]
