Mowing the lawn is a chore that serves as an excellent character building excercise for a growing child. However, children are expensive and the maintenance requirements can be prohibitive. Many instead turn to robots to lend a hand, and [Rue Mohr] is no exception. [Rue]’s creation goes by the name Mowerbot, and was first built […]
A truly random number is something that is surprisingly difficult to generate. A typical approach is to generate the required element of chance from a natural and unpredictable source, such as radioactive decay or thermal noise. By contrast it is extremely easy to generate numbers that look random but in fact follow a predictable sequence. […]
Back in the ’70s and ’80s, before we had computers that could do this sort of thing, there were fully analog video effects. These effects could posterize or invert the colors of a video signal, but for the best example of what these machines could do just go find some old music videos from Top […]
Freezers are highly useful devices. You can preserve food, stop a dead animal from stinking out your apartment, and keep your vodka at the optimal drinking temperature. Of course, most of us bought ours from the local whitegoods store, but [Tech Ingredients] set out to build his own (YouTube, embedded below). Unlike your freezer at […]
When designing furniture, material choice has a huge effect on the character and style of the finished product. Wood is a classic option, while more modern designs may use metal, plastic or even cardboard. Less popular, but no less worthy, is concrete. It’s heavy, cheap, and you can easily cast it into a wide variety […]
Some of us are able to get by in life with somewhere between 0 and 1 USB ports. We typically refer to these people as “Mac users”. For the rest of us, too much is never enough, and we find ourselves seeking out expansion cards and hubs and all manner of perverse adapters and dongles. […]
Taking an old piece of gear and cramming it full of modern hardware is a very popular project. In fact, it’s one of the most common things we see here at Hackaday, especially in the Raspberry Pi era. The appeal is obvious: somebody has already done the hard work of designing and building an attractive […]
Shaper tools were, at one time, a necessary tool for any machine shop. With a shaper and a lathe, you can rebuild or manufacture almost anything. At the very least, you can make the tool to manufacture anything. For the last few months, [Makercise] has been working on building his own homemade shaper, and now […]
After covering a few of his builds at this point, we think it’s abundantly clear that [Igor Afanasyev] has a keen eye for turning random pieces of antiquated hardware into something that’s equal parts functional and gorgeous. He retains the aspects of the original which give it that unmistakable vintage look, while very slickly integrating […]
We are very familiar with retrocomputers, and if you want you too can build a computer that could have been made in the late ’70s on a breadboard. Just grab your CPU of choice, add some RAM, some ROM, a ton of jumper wires, and give it some way to talk to the outside world. […]
