Defeat Your Car’s Autostop Feature With A Little SwitchBot

These days, many new cars come with some variant of an “auto-stop” feature. This shuts down the car’s engine at stop lights and in other similar situations in order to save fuel and reduce emissions. Not everyone is a fan however, and [CGamer_OS] got sick of having to switch off the feature every time they got in the car. So they employed a little robot...

One Coder is Porting Portal To the Nintendo 64

When Portal came out in 2007, developers Valve chose not to release the groundbreaking title on an obsolete Nintendo console long out of production. Nobody cared at the time, of course, but [James Lambert] is here to right that wrong. Yes, he’s porting Portal to the N64. The port, or “demake,” as [James] calls it, has been under construction for some...

MIDI Controller Looks Good, Enables Your Air Guitar Habit

We all want to be guitar heroes, but most of us have to settle for letting a MIDI board play our riffs using a MIDI controller. [Joris] thinks a MIDI controller should look like a cool instrument and thus the Ni28 was born. Honestly, we first thought we were looking at wall art, but on closer look, you can see the fretboard and the soundhole are festooned...

3D Printed Linear Actuator Is Cheap and Strong

Motors are all well and good for moving things, but they’re all about the round-and-round. Sometimes, you need to move something back and forth, and for that a linear actuator will do the trick. While they can be readily sourced for under $50 online, [Michael Rechtin] genuinely felt like reinventing the wheel, and managed to whip up a 3D-printed design...

Hackaday Prize 2022: Recycled Tire Table Is Where the Rubber Meets the Road

The problem with good inventions is that we usually end up with way too many of that particular widget lying around, which can cause all kinds of problems. Take the car tire, for instance. They were a great invention that helped spell the end of buggy whips and broken wagon wheels. But there are so many used-up tires about today that some people end...

The Little Big Dogs of Invention

This is a story about two dogs I know. It is also a story of the U.S. Navy, aviation, and nuclear weapons. Sometimes it is easy to see things in dogs or other people, but hard to see those same things in ourselves. It’s a good thing that dogs can’t read (that we know of) because this is a bit of an embarrassing story for Doc. He’s a sweet good-natured...

Practice Your Shopping Skills With This Self-Service Checkout Game

Self-service checkouts have become a common feature in supermarkets the world over, a trend accelerated by the coronavirus pandemic. While some may lament the loss of human contact, others relish the opportunity to do their own scanning: with a bit of practice, self-service can provide for a very fast checkout experience. Assuming, of course, that the...

Natural Language AI in Your Next Project? It’s Easier Than You Think

Want your next project to trash talk? Dynamically rewrite boring log messages as sci-fi technobabble? Happily (or grudgingly) answer questions? Doing that sort of thing and more can be done with OpenAI’s GPT-3, a natural language prediction model with an API that is probably a lot easier to use than you might think. In fact, if you have basic Python...

Sunrise Keyboard Looks The Part

If you’ve been to a bar sometime since the 1930s, you’ve probably spied someone drinking a Tequila Sunrise. It’s a drink that mimics the beautiful colors of the dawn. In much the same way, so does this Sunriser keyboard build from [crashl1445]. Built for a high-school engineering project, the build looks resplendent with its yellow case, paired with...

Color(ing) Computer Needs No Batteries

While Radio Shack did have the Color Computer, we don’t think they had this in mind. [Pepepépepe] has some coloring book pages and simple rules that let you simulate logic circuits using a crayon. The downloadable ‘zine has hand-written instructions and several examples. Keep in mind, this is a computer in the same way the old logic kits in the 1960s...
