Arthur C. Clarke said that "any sufficiently advanced technology is indistinguishable from magic." Even though we know that something isn't "magic", it's nice to see how close we can get. [Dofl] and h...

Smartwatches are pretty great. In theory, you'll never miss a notification or a phone call. Plus, they can do all kinds of bio-metric tracking since they're strapped to one of your body's pulse points...

Every hobby needs to have a few people who take it just a little too far. In particular, the aviation hobbies – Radio control flying, FPV multicopter racing, and the like – seem to insp…

When we wrote about [Dan Beaven]’s resin printer a while back he enthusiastically ensured us that, thanks to the recent wave of attention, he would finally finish the project. That’s wh…

Over the last decade or so, battery technology has improved massively. While those lithium cells have enabled thin, powerful smartphones and quadcopters, [patrick] thought it would be a good idea t…

Radio control boats usually bring up thoughts of racing catamarans, or scale sailing yachts. This build takes things in a slightly different direction. A radio controlled lifeboat with a built-in F…

If there are two things we love here at Hackaday, it's games and automating mundane tasks by adding a lot of electronics and voice control. A game room is, therefore, the perfect sandbox for projects ...

If you aren’t already living on the spacecraft Discovery One, you may not have HAL listening to your every voice command. If that’s the case for you, as it is for us, you may have to re…

Food. A necessary -- often delicious -- interruption of whatever project you're currently hacking away at. Ordering takeout gets expensive and it's generally unhealthy to subsist solely on pizza. With...

[This Old Tony] has a few videos that have made appearances on Hackaday. His latest one is CNC Dummies for Routers (see below). The subtitle, CNC Basics, is an honest one. If you're already well ver...

[Prusa]'s business is doing great. This year, he released the Prusa i3 Mk. 2, a four color upgrade to the printer, and sales are through the roof. There's just one problem: Paypal just locked his fund...

We’ve known a few people over the years that have some secret insight into antennas. To most of us, though, it is somewhat of a black art (which explains all the quasi-science antennas made o…

Our wonderfully creative community has a penchant for clocks. We have seen so many timepieces over the years that one might suppose that there would be nothing new, no instrument of horology that woul...

A tachometer used to be an accessory added to the dash of only the sportiest of cars, but now they're pretty much standard equipment on everything from sleek coupes to the family truckster. If your d...

The modern human’s worst nightmare: a power outage. Left without cat memes, Netflix, and — of course — Hackaday, there’s little to do except participate in the temporary ana…

Today is Cyber Monday, the day when everyone in the US goes back to work after Thanksgiving. Cyber Monday is a celebration of consumerism, and the largest online shopping day of the year. Right now, ...

We recently went through our twice yearly period of communal venting called adjusting for daylight saving time (DST), or British Summer Time (BST) as it’s called in the UK. But why are we cha…

Five or so years ago, Intel rolled out something horrible. Intel’s Management Engine (ME) is a completely separate computing environment running on Intel chipsets that has access to everythin…

A while back I looked at lubricants for the home shop, with an eye to the physics and chemistry behind lubrication. Talking about how to keep parts moving got me thinking about the other side of th…

This is likely the world’s smallest fully-functional Game Boy Color, able to play all of the games using the tiny direction pad and buttons, with onboard display and battery and in the origin…
