Soak up the Sun with this 3D Printed Solar Harvester

At first glance, adding solar power to your project might seem easy. Get a photovoltaic panel, point it towards the big ball of burning gas in the sky, and off you go. But in reality, there’s a bit more to it than that. Especially when you’re trying to do something …read more

Swanky solar-powered table wirelessly charges multiple devices at once

More and more phones and devices are able to be charged wirelessly these days, but that usually still requires a pad for each that takes up a power plug. Now, a Spanish start-up called Proton New Energy Future has unveiled Ebörd, a smart tabl… Continue reading Swanky solar-powered table wirelessly charges multiple devices at once

Solar Circuit Sculpture Pumms the Night Away

A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with.

For the unfamiliar, a pummer is a device from the BEAM style of robotics, …read more

Self-Powered Sun Tracker Takes a Cue from NASA Solar Probe

Getting a solar array to track the sun has always been an interesting problem, and it has led to some complicated solutions. Controllers that use GPS and servos seem to be much in favor these days, but as this NASA-inspired sun tracker shows, the task needn’t be overly complex.

It’s pretty obvious from the video below that [NightHawkInLight]’s solar tracker is just a proof-of-concept for now, but it certainly shows promise. It’s based on NASA’s sun-skimming Parker Solar Probe, which uses sensors at the rear of the probe to maneuver the craft to keep sunlight from peeking around the sides …read more

Perfecting the Solar Powered Web Server

Running a server completely off solar power seems like it would be a relatively easy thing to do: throw up a couple of panels, tack on a charge controller and a beefy battery, and away you go. But the reality is somewhat different. Most of us hackers are operating on a relatively limited budget and probably don’t have access to the kind of property you need to put out big panels; both pretty crippling limitations. Doing solar on a small-scale is hard, and unless you really plan ahead your setup will probably be knocked out on its first cloudy day. …read more

Solar Power For Chernobyl’s Second Generation of Electricity

When featuring cool hacks repurposing one thing for something else, we prefer to focus on what we could get our hands on and replicate for ourselves. Not this one, though, as nobody else has the misfortune of being responsible for 2,000 square kilometers (772 square miles) of radioactive contaminated land like the government of Ukraine. Trying to make the best of what they have, they’ve just launched a pilot program working to put up solar power farms inside the Chernobyl Exclusion Zone.

This is sure to invite some jokes in the comments section, but the idea has merit. Thirty years …read more

Big Power, Little Power, Tiny Power, Zap!

Our Hackaday Prize Challenges are evaluated by a panel of judges who examine every entry to see how they fare against judging criteria. With prize money at stake, it makes sense we want to make sure it is done right. But we also have our Hackaday Prize achievements, with less at stake leading to a more free-wheeling way to recognize projects that catch our eye. Most of the achievements center around fun topics that aren’t related to any particular challenge, but it’s a little different for the Infinite Improbability achievement. This achievement was unlocked by any project that impressed with …read more

Home Brew Solar Cells for the Chemically Curious

The idea of making your own semiconductors from scratch would be more attractive if it weren’t for the expensive equipment and noxious chemicals required for silicon fabrication. But simple semiconductors can be cooked up at home without anything fancy, and they can actually yield pretty good results.

Granted, [Simplifier] has been working on the method detailed in the video below for about a year, and a look at his post on copper oxide thin-film solar cells reveals a meticulous approach to optimize everything. He started with regular window glass, heated over a propane burner and sprayed with a tin oxide …read more

Living On The Moon: The Challenges

Invariably when we write about living on Mars, some ask why not go to the Moon instead? It’s much closer and has a generous selection of minerals. But its lack of an atmosphere adds to or exacerbates the problems we’d experience on Mars. Here, therefore, is a fun thought experiment about that age-old dream of living on the Moon.

Inhabiting Lava Tubes

The Moon has even less radiation protection than Mars, having practically no atmosphere. The lack of atmosphere also means that more micrometeorites make it to ground level. One way to handle these issues is to bury structures under …read more
