This team project for the Hackaday Prize is a solution to a rather important problem. Imagine growing plants for use as biomarkers for pollution. It’s a great idea, but how do you grow the pl…

Setting up a cluster of computers used to be a high-end trick used in big data centers and labs. After all, buying a bunch of, say, VAX computers runs into money pretty quickly (not even counting t…

The Hack42 Hackerspace in Arnhem, Netherlands is one of the best hackerspaces we’ve ever seen. After taking over a decommissioned military base, the Hack42 crew has filled a compound rimmed w…

Of all the things evolution has stumbled across, the eye is one of the most remarkable. Acting as sort of a 'biological electromagnetic transducer', the eye converts incoming photons into electrical a...

[Justin] had been trying to find a good tube amp for years, but all the best examples were either expensive or a complete basket case. Instead of buying a vintage stereo tube amp, he decided to build ...

Automation makes the world go around. Whether it's replacing elevator attendants with buttons, replacing songwriters with computer algorithms, or giving rovers on Mars the same sense and avoid capabil...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors…

Many of you will probably at some point have looked at a satellite dish antenna and idly wondered whether it would collect useful amounts of heat if you silvered it and pointed it at the sun. Perhaps...

An essential skill for a maker is the ability to improvise or re-purpose existing materials into new parts. Sometimes, one needn't make many modifications to create something new, as is the case with ...

Home-made transportation is a thriving area for makers to flex their skills. Looking to shorten their university commute, [doublecloverleaf] modded his penny board by adding a motor that can have him ...

If you’re like us, you spend most of your time in front of a computer keyboard, wondering where your life went wrong. [AnonymouSmst] has a slightly more positive outlook on life, which led th…

We all know that it's not the volts that kill you, it's the amps. But exactly how many electrons per second are there in an amp? It turns out that nobody really knows. But according to a press release...

We'll just come out and say it, [reboots] has friends with nice garbage. Sure, some of us have friends who are desperately trying to, "gift," us a CRT monitor, hope dropping like a rock into their st...

A few months ago, a very inexpensive 3D printer appeared on Monoprice. My curiosity for this printer was worth more than $200, so I picked one of these machines up. The Monoprice MP Select Mini is …

We sometimes look back fondly on the old days where you could–it seems–pretty easily invent or discover something new. It probably didn’t seem so easy then, but there was a time w…

A lot of us spend a lot of time switching between Windows and Linux. Now that platforms like the Raspberry Pi are popular, that number is probably increasing every day. While I run Linux on nearly …

The Hackaday SuperConference is the greatest gathering of hardware hackers on the planet. Last year at the SuperCon, we saw talks on building systems from scratch, creating new and interesting uses fo...

A must-have peripheral for games consoles of the 1980s and 1990s was the light gun. A lens and photo cell mounted in a gun-like plastic case, the console could calculate where on the screen it was …

Warranty? We don't need no stinking warranty! We're hackers, and if you have access to a multi-million dollar CNC machine and 3D CAM software, you mill your own headphone replacement parts rather tha...

It wasn’t long ago that faced with a controller project, you might shop for something with just the right features and try to minimize the cost. These days, if you are just doing a one-off, i…
