In the secret Hackaday bunker, we have some emacs users, some vi users, and some people who don’t really care. However, even the staunchest of our emacs supporters had to do a double take at [Vreeze’s] project that creates a GameBoy emulator using the venerable text editor. You can see [Alexei Nunez’s] reaction to the […]
Historically speaking, lithophanes are images made in porcelain with an etching or moulding process, in which an image is visible when backlit due to the varying thickness of the material. Porcelain isn’t the easiest thing to work with, but thankfully for those of us in the present, 3D printers are here to make everything better. […]
While we often think we are clever designers, living things often meet or beat the best human designs. It is easy to forget that nature even has living lightbulbs, among them the firefly. Researchers from Penn State decided to compare how fireflies create light and found that they deal with a problem similar to LEDs. […]
Google has promised us new hardware products for machine learning at the edge, and now it’s finally out. The thing you’re going to take away from this is that Google built a Raspberry Pi with machine learning. This is Google’s Coral, with an Edge TPU platform, a custom-made ASIC that is designed to run machine […]
According to [makeTVee], his latest project started out as an experiment to see how well the LED matrix techniques he’s worked with in the past would translate to a cylindrical form factor. We’re going to go ahead and say that not only was the test a success, but that the concept definitely holds promise for […]
Water is a stable chemical, but with the addition of a little electricity, it can be split into its component parts. The result is just the right mix of H2 and O2 to convert back into water with a bang. [Peter Sripol] has built a charming desktop cannon in just such a way. The build […]
Oddly, there’s been a few recent outbreaks of measles. It struck me how when I was a kid, a few hundred kids getting measles wouldn’t have been news at all. However, even a handful makes the news now, since in 2000 the Center for Disease Control declared measles eradicated in the United States. So how […]
For the odd job every now and then, a regular screwdriver does the job. However, in situations like a small production operation, it can quickly become uncomfortable to use. In these situations, an electric screwdriver is incredibly useful. There’s no need to rush out to the store, however – you can build one yourself, and […]
Code documentation — is there anything more exciting than spending your time writing extensive comments? If I had to guess, your answer is probably somewhere along the lines of “uhm, yes, everything is more exciting than that”. Plus, requesting to document your code is almost like an insult to your well thought out design, this […]
Where does your mind go when you think of 3D printed parts? Running off hard to find replacement components? Maybe spinning up a bespoke electronics enclosure? Occasionally the little boat that you can compare to the little boats of others online? All reasonable enough answers. But thanks to the work of [Matthew Wentworth], you might […]
