There are a variety of means by which numbers can be displayed from an electronic circuit, and probably the most ubiquitous remains the seven-segment display. Take seven LEDs, lamps, LCDs, VFD segments or mechanical flip-dot style units in the familiar rectangular figure eight, and your microcontroller or similar can display numbers. There are a variety […]
Due to pedalboard size, complicated guitar pedals sometimes reduce the number of buttons to the bare minimum. Many of these pedals are capable of being controlled with an external MIDI controller, however, and necessity being the mother of invention and all, this is a great opportunity to build something and learn some new skills at […]
Blindsided by missing pin allocations? Perhaps you’re working on a piece of hardware and you notice that the documentation is entirely wrong. How can you get your device to work? [Dani Eichhorn]’s troubles began when running an IoT workshop using a camera module. Prior to the work, no one had through to check if all […]
If you thought your handheld digital oscilloscope was the most transportable of your signal analyzing tools, then you’re in for a surprise. This oscilloscope made by [Mark Omo] measures only one square inch, with the majority of the space taken up by the OLED screen. It folds out into an easier instrument to hold, and […]
Most of the projects we feature on Hackaday are built for personal use; designed to meet the needs of the person creating them. If it works for somebody else, then all the better. But occasionally we may find ourselves designing hardware for a paying customer, and as this video from [Proto G] shows, that sometimes […]
For many environmental enthusiasts, horizontal-axis wind turbines (HAWTs) — the kind that look like windmills slowly spinning in the distance — are a pretty familiar sight. Unfortunately, there are quite a few caveats that make them harder to adopt despite the fact that harvesting renewable energy sources is more sustainable than relying on natural gas […]
[Starhawk] is a man with a problem. More accurately, he’s a man whose mother has a problem, but ultimately that ends up being the same thing. Her wide-format Canon printer recently stopped working after better than a decade of reliable service, and he wants to know why. Rather than spend the money on buying a […]
Us: “I’ll take Retro style displays we absolutely have to have for $200, Alex.” Trebek: “This nixie tube is unlike any conventional tube you’ve seen before, handbuilt and NOT numbers or letters.” Us: “What is FriendlyWire’s new logo tube?” Trebek: “Heck yeah.” Nixie tubes are the vacuum technology that manages to do far less than […]
