Getting young kids excited about technology and engineering can be a challenge, and getting them interested in the environment isn’t exactly a walk in the park either. So any project that can…

What do you do when you have a gigantic old drum sander with a bent table? Scrapping it will give you a few cents per pound, but this machine is just too cool, and would be too useful to just throw…

What if you could play video games perfectly? Would you be one of the greats, raking in millions of dollars simply by playing competitive Fortnite? That’s what Twitch does. Twitch plays video…

Your hands are filthy from working on your latest project and you need to run the water to wash them. But you don’t want to get the taps filthy too. Wouldn’t it be nice if you could jus…

We see so many clocks here at Hackaday, and among those we see our fair share of binary clocks. But to see one that at first sight looks as though it might be a commercial product when it is in fac…

Say you have a guitar, an expensive guitar – one of only three like it. And say this guitar sounds great, but it’s missing something. It needs something, but something that won’t …

When we were in school, every description of how transistors work was pretty dry and had a lot of math involved. We suppose you might have had a great instructor who was able to explain things more…

It’s probably not much of a stretch to say that many of us have taken on a project or two that were little more than thinly veiled excuses to add a new tool or piece of gear to our arsenal. T…

We like a good video game as much as the next person. Heck, a few hours wasted with “Team Fortress 2” on a couple of big monitors is a guilty pleasure we’ll never be ashamed of. B…

The modern Internet can be a dangerous place, especially for those who might not have the technical wherewithal to navigate its pitfalls. Whether it’s malware delivered to your browser throug…

We sometimes wonder if designers ever actually use their own products, or even put them through some sort of human-factors testing before putting them on the market. Consider the mechanism that sec…
