Machinists are expected to make functional items from stock material, at least hat’s the one-line job description even though it glosses over many important details. [Eclix] wanted a birthday…

Little humans have a knack for throwing a wrench in the priorities of their parents. As anyone who’s ever had children will tell you, there’s nothing you wouldn’t do for them. If …

While Apple products have their upsides, the major downside with them is their closed environment. Most of the products are difficult to upgrade, to say the least, and this is especially true with …

Morse code — that series of dots and dashes — can be useful in the strangest situations. As a kid I remember an original Star Trek episode where an injured [Christopher Pike] could only…

Most time-lapse videos of 3D prints show a steadily growing print with a crazy blur of machine movement everywhere else. This is because an image is captured at a regular time interval, regardless …

Getting a project off the ground often means an up-front investment in parts. Hackaday is upping our efforts to smooth out that obstacle for those who want to Build Something That Matters. Seed fun…

Most people probably don’t think about springs until one kinks up or snaps, but most of the world’s springs are pretty crucial. The ones that aren’t go by the name Slinky. We all use and enco…

What happens to your 3D printer if the power goes out? What happens if there’s a jam in the nozzle? What happens if your filament breaks, runs out, or turns into a plate of spaghetti? For all…

The cool kids these days all seem to think we’re on the verge of an AI apocalypse, at least judging by all the virtual ink expended on various theories. But our putative AI overlords will hav…

Do you need a fancy fan cover with precisely specified attributes, but have no desire to design one from scratch? If you answered yes (or no) then [mightynozzle] has the answer. The Customizable Fa…

The International Space Station is one of our leading frontiers of science and engineering, but it’s easy to forget that an exotic orbiting laboratory has basic needs shared with every terres…

You might remember a time when people thought portable DVD players were a pretty neat idea. In the days before netbooks, cheap tablets, and arguably even the widespread adoption of smartphones, it …

Experience — or at least education — often makes a big difference to having a successful project. For example, if you didn’t think about it much, you might think it is simple to c…

We’ve become used to software-defined radio as the future of radio experimentation, and many of us will have some form of SDR hardware. From the $10 RTL USB sticks through to all-singing, all…

Pi-hole is an open source project to turn that Raspberry Pi collecting dust in your drawer into a whole-network ad blocking appliance. Not only does it stop ads from showing up on all your computer…

Let’s face it, everybody wants to build a Stirling engine. They’re refined, and generally awesome. They’re also a rather involved fabrication project which is why you don’t …

The worst thing about walking around while trying to follow directions is that you have to keep looking down at them to get the next turn. At best, you’ll miss out on the scenery; at worst, y…

If you want to blink a ton of WS2812-alike LED pixels over WiFi, the hardware side of things is easy enough: an LED strip, and ESP8266 unit, and a beefy enough power supply to feed them. But the so…

Small pinwheel type ion motors fall into the category of a fun science experiment or something neat to do with high voltage, but Hackaday’s own [Manuel Rodriguez-Achach] added a neat twist th…

Here’s a Big Mouth Billy Bass with extra lip thanks to Alexa. If you’re not already familiar, Big Mouth Billy Bass is the shockingly popular singing animatronic fish designed to look li…
