We’ve known people to put down a small ice rink in their back yard during the winter. But a machine to resurface these diy rinks is unheard of until now. The big name in rink resurfacing is Zamboni, the person who invented this method of keeping the ice pristine. This has almost everything you would find on [...]

At Hackaday, we’ve seen enclosures built out of just about every material. From wood, glass, epoxy resin, plastic, and even paper, all these different types of enclosures provide some interesting properties. Sometimes, though, you need an enclosure made out of metal and welding together steel cases isn’t exactly easy or cheap. [manekinen] came up with a [...]

This is not photoshopped, it’s a real gauntlet made of brass. [David Guyton] crafted it for some promotional photos for his book. But he also took the time to put together a step-by-step build tutorial. The process starts with paper templates. These are much easier to work with than metal stock so [David] spends quite [...]

We have no idea how well this diy fume extractor works, but it sure does look great! We’ve been thinking that it’s time to stop trying to blow away the solder fumes while working on project and this might be just the kind of motivation we need. The 6″ cube doesn’t get in the way [...]

We’re impressed by the ARM prototyping board which [Danjovic] is showing off. He proves that in this day of ever shrinking packages it’s still possible to make your own development tools with protoboard and a soldering iron. To tell you the truth, if he had designed and etched his own board we probably wouldn’t have [...]

For those that absolultely can’t wait to get to experience the Oculus Rift, you can follow these plans to build your own. MTBS3D forum user [Rfurlan] pledged in the oculus rift kickstarter (which concluded last night), but simply couldn’t wait till November/December to get his developer kit. That, and he’s probably only getting one, and [...]

[Jerry] missed the laser cutters he had been using at the local TechShop. It closed down and after seeing some hardware in a surplus store he decided to build a laser cutter to call his own. You won’t be disappointed by his build log. It’s got a ton of hi-res images and plenty of explanation. [...]

[Tim] drives a 1995 Mitsubishi TS Magna, which is equipped with a less than stellar accessory package he lovingly calls a “poverty pack”. He outfitted his ride with an aftermarket head unit that can support the Bluetooth A2DP profile, provided he buys the ridiculously overpriced kit sold by Pioneer. Reluctant to shell out more money [...]

[Jozef] has been playing around with X-rays. Specifically, he’s been using his own setup to make fluoroscopic images, a type of x-ray photography that allows for video images to be made. If you’ve ever seen those x-ray movies of someone swallowing, that’s fluoroscopy (we’re fans of the other oddities like this video of a skeleton playing [...]

This is a great project for a slow afternoon, or a beginners introduction to DIY. [William] shows off a really simple speaker project that results in a light show as well as a decent enclosure. He’s using a PVC elbow to mount the speakers. They’re just glued in place. Below that, a section of clear [...]

[Andreas] wrote in to let us know about this DIY Neurophone project. Apparently a Flanagan Neurophone uses ultrasound in some manner to transmit audio directly to the body, or nervous system? Needless to say we are a bit skeptical of anyone whose wiki page leads directly to pyramid power. In fact most of the references [...]

Inspired by a non-existant yet still cool illuminated bicycle handlebar project, [Becky] over at Adafruit came up with her own version of light up handlebars. Not only is her project actually real, they’re also a pretty cool build that brings a little lightcycle ambiance to twilight bicycling. [Becky]‘s light up handlebars are inspired by the GLOBARS [...]

Chaos Communication Congress 24th (24C3) 2007 Abstract: The apocalypse could happen any day. You're going to need things to survive and your going have to make them yourself. Whether it's a red button, volcano, avian bird flu, meteor, cosmic superhighway or economic collapse, this lecture will give you the information you need to make things that will increase your chances of survival. This lecture will present a broad array of projects that will be both practical and humorous. Some projects are projects that I have made and will have on hand to demonstrate including a diy water purifier and steam-engine powered battery charger. I'll also point the way to over the top projects like making an EMP Generator to deal with the robot uprising.

This rig looks so good it’s hard to believe this is the first ROV that [DZL] has ever built. It houses an HD camera which feeds the display at the operator’s station. You can see the controller to the left of that screen which uses a joystick and buttons to pilot the underwater vessel. In [...]

[Teknynja] was looking for a way to control several discrete AC-powered devices using a microcontroller, and while he did consider the Powerswitch tail 2 from Adafruit, handling 5 devices would get pretty expensive. Rather than buying a complete off the shelf solution, he decided to build his own 5-way switched outlet. He picked up a [...]

[GuShH] wrote a guide for making your own rosin-based solder flux. According to [Stephen] — who sent in the tip and tried this method himself — is works well, it’s cheap, but you will need to clean up a bit after using it on a PCB. Only two ingredients are necessary to make your own [...]

[Ericdsc] is looking to capture the electrical impulses of his muscles by using an EMG.

There comes a time in every maker’s career where solderless breadboards won’t do, perfboard becomes annoying, and deadbug is impossible. The solution is to manufacture a PCB, but there’s a learning curve. After learning a few tricks from [Scott]‘s awesome DIY PCB guide, it’s easy to make your own printed circuit boards. There are a [...]

If you’re running your own recording studio, you’re going to need a lot of gear that seems excessively esoteric to the non-musically inclined. A rack full of synth gear looks just like any other cabinet of technology you would find in a server room. Electronic music is, for the most part, very utilitarian looking, but [...]

Chaos Communication Congress 27th (27C3) 2010 Abstract: At least if you have used all the features of a synthesizer, you probably ask the questions: "How can I modify it? How can I build a synthesizer myself? What features do I personally need?" This talk covers this topic from a theoretical and technical point of view. Since commercial synthesizers have been built, the interest in modifying existing synthesizers and building own synthesizers has increased. Nowadays there is a much bigger DIY (Do-It-Yourself) community, and the idea of building own synthesizers and modules has been even merged with the idea of open-source and creative-commons hardware. This gives a wide range of new possibilities. Another part of the talk will be a quick introduction of less or more known DIY-synthesizer projects and the demonstration of a DIY synthesizer based on MOS 6581-like synthesis (The Commodore SID), which can be built from quite cheap electronic components and give a wide range of possibilities for sound generation and a reasonable sound. This talk will briefly describe the basics of sound synthesis and what makes it so interesting. A little bit of basic knowledge is recommended, but not necessary.

When it’s time to get started on a project and put our irons in the fire, we usually reach for a nice Weller or Hakko soldering iron.
