Running suspicious software in a virtual machine seems like a basic precaution to figure out whether said software contains naughty code. Unfortunately it’s generally rather easy to detect whether or not one’s software runs inside a VM, with [bRootForce] going through a list of ways that a VirtualBox VM can be detected from inside the […]
The gear pump prototype in action. (Credit: Artisan Makes, YouTube) Hydraulic gear pumps are deceptively simple: just two gears rotating together, forcing the hydraulic oil from one side to the other where the teeth don’t meet, and thus providing the ability to pressurize said oil to make hydraulic cylinders, final drives, etc. do their thing.

For anyone who’s joined us for previous years, you’ll know that badge hacking and modification are core to the Hackaday Supercon experience. While you’re of course free to leave the badge completely stock, we encourage attendees to tear it apart, learn how it works, and (hopefully) rebuild it into something unique. There are even prizes […]

In an era where running a website without HTTPS is shunned, and everyone wants you to encrypt your DNS queries, you’d expect that the telecommunications back-ends are secured tightly as well. Especially the wireless bits between terra firma and geosynchronous communication satellites. But as recently discovered by US researchers, the opposite is actually true. The […]
One of the lost pleasures of our modern world is the experience of going shopping at a grocery store, a mall, or a drugstore, and finding this month’s electronics magazine festooned with projects that you might like to build. Sure, you can find anything on the Internet, but there’s something to be said about the […]
If you ever wanted to win a bar bet about a world record, you probably know about the Guinness book for World Records. Did you know, though, that there are some robots in that book? Guinness pointed some out in a recent post. Ever wonder about the longest table-tennis rally with a robot or the […]
