There’s no doubt the venerable internal combustion engine is under fire. A recent patent filing from Ford claims it can dramatically reduce emissions and, if true, the technology might give …read more Continue reading Ford Patent Wants to Save Internal Combustion
We gotta love hacker Dads and Moms for being so awesome. Sooner or later, their kids get to play with some amazing toy that every other kid on the block …read more Continue reading Dad Builds Frickin’ Tank For His Son
What’s this? News about robot dogs comes out, and there’s no video of the bots busting a move on the dance floor? Nope — it looks like quadruped robots are …read more Continue reading Hackaday Links: August 14, 2022
It is no secret that we like simulating circuits before we build something and there are plenty of great tools for that. But what about those of us who work …read more Continue reading Hack Your Engine Virtually
When we think of tracked vehicles, we normally think of tanks, or perhaps heavy construction machinery. Meanwhile the average member of the public is left out of the fun. [Bob] …read more Continue reading Ride-on Tracked Vehicle Is A Stout Metal Build
Climate change promises to cause untold damage across the world if greenhouse gas emissions continue at current levels for much longer. Despite the wealth of evidence indicating impending doom, governments have done what humans do best, and procrastinated on solving the issue.
However, legislatures around the world are beginning to …read more
Electric cars, as a concept, were once not dissimilar from the flying car. Promised to be a big thing in the future, but hopelessly impractical in the here and now. However, in the last ten years, they’ve become a very real thing, with market share growing year on year as …read more

Whether you’re into fruit smoothies or icy blended cocktails, a blender comes in handy when preparing these beverages in the kitchen. But, if a small electric motor can do the job well, a noisy combustion engine can certainly do it louder. This is demonstrated ably by this project from [JT …read more
Although there was briefly a company called Rotary Rocket, the term is much better known as a nickname for the Mazda RX-7 — one of the few cars that used a Wankel, or rotary, engine. If you ever wondered how these worked, why not print a model? That’s what [Engineering Explained] did. They printed a 1/3 scale model and made a video explaining and demonstrating its operation. The model itself was from Thingiverse, created by [EricThePoolBoy].
One thing we really liked about the model was the use of lights to show the different stages of combustion. Cool air intake is …read more

We love a good clock build around here, especially if it tells time in a unique way. This 4-stroke digital clock designed by [lagsilva] takes the checkered flag in that category. As it displays the time, it also demonstrates the operation of an internal combustion engine. The numbers take the form of pistons and dance an endless repetition of intake, compression, combustion, exhaust.
The clock’s digits are made from two LED matrices driven by an Arduino Uno and a couple of MAX7219 driver boards. The dots that form the digits move up and down the matrices in 1-3-4-2 firing order. …read more
