Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt battery are soldered onto a four pin Hall effect sensor which can toggle one of two lights […]
If you’ve put in all the necessary practice to learn bike tricks, you’d probably like an appropriately dramatic soundtrack to accompany your stunts. A team of students working on a capstone project at the University of Washington took this natural desire a step further with the Music Bike, a system that generates adaptive music in […]
We know you’ve seen them: the time-lapses that show a 3D print coming together layer-by-layer without the extruder taking up half the frame. It takes a little extra work compared to just pointing a camera at the build plate, but it’s worth it to see your prints materialize like magic. Usually these are done with […]
We’re not sure how we managed to miss this one, but better late than never, right? This is Trinteract, a 3-DOF input device that’s both open-source and Arduino compatible. There’s even a neat 3D-printed clip to add it to the side of your laptop. Imagine navigating 2D and 3D environments, or flying around in Minecraft […]
