Most of us are more bits-and-bytes than nuts-and-bolts, but we have the deepest appreciation for the combination of the two. So, apparently, does [rectorsquid]. Check out the design and flow of his…

We like cheap FPGA boards. It isn’t just that we’re cheap — although that’s probably true, too — but cheap boards are a good way to get people started on FPGAs and we …

Even if you don’t like disco, you might like the slick moves that went into this project. [W&M] built a miniature motorized mirror ball inside of a standard incandescent light bulb, and t…

How would you approach a build that required you to hack apart a perfectly good console motherboard? With aplomb and a strong finish. [jefflongo] from [BitBuilt.net] — a forum dedicated to ma…

Today, when we say “Jesus nut”, we’re not referring to the people who spend their days proselytizing down at the mall. The term, likely spawned in the Vietnam war, refers to the m…

Kyleigh has an eye-controlled computer on her wheelchair but something as simple as her bedroom door was still beyond her reach… until now! [Bill Binko], recently filmed a demo of an automati…

If you want to measure AC or DC current with an oscilloscope, a current clamp is a great way to do it. The clamp surrounds the wire, so you don’t need to break the connection to take your mea…

The Talking Clock service is disappearing, and it’s quite possible that few of you will be aware of its passing. One of the staples of twentieth-century technology, the Talking Clock service …

Prolific maker [Sean Hodgins] has taken the wraps off of his latest one-day build, and as usual, it takes the kind of spare parts most people reading Hackaday will have in their parts bins and turn…

We can say one thing for [bitluni]: the BOMs for his projects, like this ESP32 AM radio transmitter, are always on the low side. That’s because he leverages software to do jobs traditionally …

In case you haven’t heard, we have a 3D printing contest going on right now. It’s the Repairs You Can Print Contest. The idea is simple: show off how you repaired something with a 3D pr…

People who exercise with fitness trackers have a digital record of their workouts. They do it for a wide range of reasons, from gathering serious medical data to simply satisfying curiosity. When f…
