String instruments have a long history in civilization, helping humans make more complex and beautiful music. We wonder what our forebears would think of this guitar strummed with 1000 picks? [Mattias Krantz] wondered what the best number of picks was to play guitar and took the experiment to its illogical extreme. Starting with zero picks […]
In the late 1800s, the stereograph — sometimes incorrectly called a stereopticon — was a big craze. You’d view two side-by-side images through some lenses and see a three-dimensional image. This, of course, later would morph into View-Masters and, eventually, virtual reality headsets. But if you have an old stereograph, where do you get new […]
Remote-controlled cars can get incredibly fast and complex (and expensive) the farther into the hobby you get. So much so that a lot of things that are missing from the experience of driving a real car start to make a meaningful impact. [Indeterminate Design] has a few cars like this which are so fast that […]

Making something enjoyable often requires a clever trick. It could be a way to cut something funny or abuse some peripheral in a way it was never designed for. Especially good tricks have a funny way of coming up again and again. [DERAILED3D] put a 3d printed benchy in a bottle with one of the […]
Every now and then, a commercial product aims to help you in your life journey, in a novel way, making your life better through its presence. Over the years, I’ve been disappointed by such products far more often than I have been reassured, seeing each one of them rendered unimaginative and purposeless sometimes even despite […]
[Breaking Taps] has done some lithography experiments in the past, including some test patterns and a rudimentary camera sensor. But now, it’s time to turn it up a notch with 1µm garage semiconductor ambitions. The e-beam lithography he’s done in the past can achieve some impressive resolutions, but they aren’t very fast; a single beam […]
There was even a day not too long ago when printers appeared to be going the way of the dodo; remember the “paperless office” craze? But then, printer manufacturers invented printers so cheap they could give them away while charging $12,000 a gallon for the ink, and the paperless office suddenly suffered an extinction-level event […]
To drive a MOSFET requires more than merely a logic level output, there’s a requirement to charge the device’s gate which necessitates a suitable buffer amplifier. A variety of different approaches can be taken, from a bunch of logic buffers in parallel to a specialised MOSFET driver, but [Mr. T’s Design Graveyard] is here with […]
Inspiration can strike a maker at any moment. For [Laura Kampf], it happened in the desert when she saw a tumbleweed. Tumbleweeds roll through the western United States, hitting cars on the interstate and providing some background motion for westerns. [Kampf] found the plant’s intricate, prickly structure mesmerizing, and decided to turn it into a […]
