This Motorless Pull-Behind Mower is Made From Junk

Cutting a field of grass is a straightforward and satisfying process, given a suitably powered mover. A tractor with a rotary topper to hang on its three-point linkage and power-take-off will make short work of the task. [Donn DIY] had an agricultural quad-bike, but when it came to mowing its…...

Hackaday Prize Entry: A Simple CNC

3D printers are all the rage, but there’s still space for more traditional CNC machines. For their Hackaday Prize entry, [Andy], [Tim], and [Chris] are building the Sienci Mill – a simple desktop CNC mill that’s able to cut drill and carve everything from wood to circuit boards. As far…... [Continue...]

Ham Antenna Rises to the Occasion

There was a time when you could do what you wanted in your yard and hams could build giant antenna farms. These days, there are usually laws or deed restrictions that stop that from happening. Even if you can build an antenna, you might want to quickly put up something…... [Continue...]

Hacker-Friendly SBCs: Which ones?

We have run out of fruits to name all the single-board computers on the market, but that doesn’t mean you can’t buy a rotten one. Bad documentation, incomplete specifications and deprecated firmwares are just some of the caveats of buying only by price and hardware features. To help you out in case…... [Continue...]

LEGO Monowheel Corners Like It’s On Rails

[Jason]’s at it again. This time the LEGO maestro is working on a LEGO BB-8 droid. As a first step he’s made a motorized monowheel that not only races along hallways and through living rooms at the peril of any passing people, but turns as well. To drive it forward…... [Continue...]

Government Drones to Toss M&Ms to Prarie Dogs

We hear a lot about drone surveillance, drone package delivery, drone this, and drone that. Honestly, though, the best use of drones has been taking cool aerial videos and posting them online. Until now. The US Fish and Wildlife Service plans to cover acres upon acres of prairie-dog habitat with…... [Continue...]

How to Measure the Extremely Small: Atomic Mass

How does one go about measuring the mass of an object? Mass is defined as the amount of matter an object contains. This is very different from weight, of course, as the mass of our object would remain the same despite the presence or size of a gravitational field. It…... [Continue...]

Controlling Bus Pirate with Python

Scott W Harden writes, “After using the AVR-ISP mkII for years (actually the cheap eBay knock-offs) to program ATMEL AVR microcontrollers, today I gave the Bus Pirate a shot. Far more than just a microcontroller programmer, this little board is basically a serial interface to basic microcontroller peripherals.” Full details at SWHarden…... [Continue...]

Microcontrollers now substitute for CPUs

Microcontrollers are getting faster and faster, as is most of the rest of the computing world. Just like you can play Nintendo console games on the newest Nintendo handhelds, it seems that modern microcontrollers can replace CPUs on personal computers from the 80s. At least, that’s what [Dave] has shown…... [Continue...]

Learn Resin Casting Techniques: Cold Casting

Sometimes we need the look, feel, and weight of a metal part in a project, but not the metal itself. Maybe you’re going for that retro look. Maybe you’re restoring an old radio and you have one brass piece but not another. It’s possible to get a very metal like part…... [Continue...]

A Drone Photosphere is Worth 4000 Times Pi Words

One of the problems with a cheap drone is getting good video, especially in real time. Cheap hobby quadcopters often have a camera built-in or mounted in a fixed position. That’s great for fun shots, but it makes it hard to get just the right shot, especially as the drone…... [Continue...]
