Push Big Red Button, Receive Power.

Posted on by

As with the age-old panic after realizing you have left an oven on, a candle lit, and so on, a soldering tool left on is a potentially serious hazard. Hackaday.io user [Nick Sayer] had gotten used to his Hakko soldering iron’s auto shut-off and missed that feature on his de-soldering gun of the same make. So, what was he to do but nip that problem in the bud?

Instead of modding the tool itself, he built an AC plug that will shut itself off after a half hour. Inside a metal project box — grounded, of course — an ATtiny85 …read more

Upgrading A USB Soldering Iron!

Posted on by

Seeing the popularity of the TS-100 soldering iron, GitHub user [ole00] found himself desirous of a few of its features, but was put off by its lack of a power supply. What is a hacker to do? Find a cheaper option, and hack it into awesomeness.

[ole00] stumbled across the inexpensive ZD-20U and — despite a handful (sorry!) of issues — saw potential: it’s compact, lightweight, and powered via a USB power cable. Wanting to use as much of the ZD-20U’s original board as possible, the modifications were restricted to a few trace cuts and component swaps. The major change …read more

Fresh-Pressed Clothes Courtesy of TEO, the Iron Man

Posted on by

As with many tasks, robots may soon be ironing our clothes for us before we leave for work. Built by a team from the University Carlos III de Madrid’s robotics lab in Getafe, Spain, TEO is a highly articulated robot, that can climb stairs, open doors, and has recently added ironing to its skill set.

Data from a depth-sensing camera in TEO’s head is combed over by an algorithm, breaking it down into thousands of points — 0 being smooth and 1 a defined line in the clothing. Comparing those point values to those of its neighbours allows TEO to …read more

Low Background Steel — So Hot Right Now

Posted on by

The nuclear age changed steel, and for decades we had to pay the price for it. The first tests of the atomic bomb were a milestone in many ways, and have left a mark in history and in the surface of the Earth. The level of background radiation in the air increased, and this had an effect on the production of steel, so that steel produced since 1945 has had elevated levels of radioactivity. This can be a problem for sensitive instruments, so there was a demand for steel called low background steel, which was made before the trinity tests. …read more

One Soldering Controller To Rule Them All

Posted on by

If your favourite programming language is solder, they you’ve surely worked your way through a bunch of irons and controllers over your hacker existence. It’s also likely you couldn’t pick one single favourite and ended up with a bunch of them crowding your desk. It would be handy to have one controller to rule them all. That’s just what [sparkybg] set out to do by building his Really Universal Soldering Controller. His intent was to design a controller capable of driving any kind of low voltage soldering iron which used either an in-line or separate temperature sensor (either thermocouple or …read more

Earth’s Core Is Squirting a ‘Jet Stream’ of Liquid Metal Under the Surface

From Shop Floor Dust To Carbon Steel

Posted on by

[Chandler Dickinson] did his monthly sweep of the floor in his blacksmith’s shop when it occurred to him that all that metal dust had to go somewhere, didn’t it? So he did the only reasonable thing and made a crude foundry out of cinder blocks, melted his dirt in it, and examined what came out the other end.

His first step was to “pan” for steel. He rinsed all the dirt in a bucket of water and then ran a magnet at the bottom of the bucket. The material that stuck to the magnet, was ripe for reclaimation.

Next he …read more

Hackaday Links: July 30, 2016

Going to DEF CON this week? Getting into Vegas early? We’re having a meetup on Wednesday, in the middle of the day, in the desert. It’s all going down at the grave of James T. Kirk. Rumor has it, the Metrons will abduct a few of us and make us fight to the death on a planet with impossible geology.

The Hara Arena is closing down. The Hara Arena in Dayton, Ohio is the home of Hamvention, the largest gathering of amateur radio enthusiasts in the US. I was there last May, and I can assure you, the Hara Arena …read more

Learn Resin Casting Techniques: Cold Casting

Posted on by

Sometimes we need the look, feel, and weight of a metal part in a project, but not the metal itself. Maybe you’re going for that retro look. Maybe you’re restoring an old radio and you have one brass piece but not another. It’s possible to get a very metal like part without all of the expense and heat required in casting or the long hours in the metal fabrication shop.

Before investing in the materials for cold casting, it’s best to have practical expectations. A cold cast part will not take a high polish very well, but for brushed and …read more
