Homebrew Stun Baton: Dangerous DIY

Are you a problem-solving field agent who refuses to use a gun to defend yourself? Or are you an Equalist looking to cover your subpar chi blocking skills? Then you’re as real as my readers. Badum-tish! You’ll also appreciate this stun baton made from off-the-shelf electronics and some recycled bits and pieces.

The baton is a pet project of UltraKeet member PodeCoet. It works by stepping up the voltage of a 4v battery to 10,000 volts through several stages, starting from two booster converter circuits, then to an inverter and finally to a voltage multiplier. Watch the result in the video below:

Head to UltraKeet for the full instructions. If you haven’t guessed by now this involves next level hackjutsu and is extremely dangerous. Also PodeCoet’s walkthrough is funny but it’s also made with colorful language, so best leave the young ones off of this one. Here’s an excerpt:

You need only get close to, and not phsyically touch these components to get a jolt, which may lead to Ventricular Fibrillation.

You can die (or sh*t your pants, sometimes both) while building this device. We are not liable for any losses or injuries, and cannot answer any support queries regarding this build.

Edit: Yes, you can still die, even if you know how to program an Arduino.

Emergency Portable SNES: Survive the Apocalypse with Super Mario World

You have to be prepared for disasters – whether it is a hurricane, a tornado, a zombie apocalypse, whatever. The end result could be that you could be without power. Forget food and water and blankets. You need to be ready to be able to play some classic Nintendo while you wait to be rescued.
emergency snes
Redditor robotairz has you covered. He has created a portable set-up that you can build yourself. This shock-proof yellow Pelican 1300 case is loaded with an SNES console, controllers, and games. It has everything two players need to keep themselves entertained for hours while civilization crumbles around them. It runs on batteries and even has a built in charger and LCD screen.

It cost about $425 to build, but being able to play Donkey Kong Country is priceless.

oneTesla Tesla Coil DIY Kit: Make Your Own Singing Lightning

Tesla coils are one of scientists’ go to tool for making science appealing to kids. As if producing your own lightning wasn’t enough, tesla coils can also be used to produce music by pulsing its sparks at appropriate frequencies. You can do all that and more with the oneTesla DIY kit. Although you might not like the “more” part.

onetesla tesla coil diy kit

The oneTesla was conceptualized by Bayley Wang, Heidi Baumgartner and Daniel Kramnik. All three are members of MITERS, a student-run tinkering shop at MIT. Which brings us to the catch of oneTesla: you have to build it yourself. Even the inventors admit that it’s best left to people with advanced skills in soldering and electronics. But that’s partly the point of the kit. I’m sure you’ll learn a lot about electronics even if you just watch or assist in assembling the oneTesla. And once it’s built, you can do this:

Flight of the Bumblebee or Attack of the Mosquitoes? The oneTesla has been such a hit at Kickstarter that its cheaper pledges have already sold out; as of this writing you’ll have to pledge at least $299 (USD) to reserve a unit, and you’ll have to wait until May to receive yours. I say it’s worth it.

Guy Builds Wind Tunnel-Cooled Computer to Help Cure Cancer

I’ve had problems with computers and video game systems overheating over the years, so I’m all for good cooling systems. And while some computer modders have solved the problem by adding more cooling fans and heat sinks, I think this build might just be a bit more than most of us need.

wind tunnel computer 1

What you’re looking at here is the Wind Tunnel Computer. It was built by Mike Schropp over at Total Geekdom, and it’s nothing short of awesome, if you ask me. Those giant ducts you see on the left and right are air intakes and outputs for the 6-foot-wide system, which is mounted in a contraction chamber in the middle designed to take full advantage of the increased air speed as it flows through.

wind tunnel computer spec

The beefy Intel Ivy Bridge 3770k powered system is overclocked to a whopping 4.5GHz, along with overclocked Radeon 7970 GPUs running on Sapphire Dual-X cards. But it doesn’t just run fast, look cool and stay cool – Mike built it for a good cause. It’s connected to the World Community Grid project, and its CPU and GPUs spend their days and night crunching numbers to help cancer researchers find a cure. And thanks to the massive throughput of the system, it’s able to push through about 20x the workload of an average 4-core system. While that’s all awesome, I do wish Mike had actually built a small wind test chamber inside of it for other science experiments. Maybe for version 2.0.

He built the system using large MDF wood panels for the vent sections, and there’s a big box fan installed in one end of it to generate the wind. Mike assembled the main computer section using custom-cut Lexan so you can see through to it, and aluminum pieces to finish the look. It’s even got a control panel on the front with LED temperature gauges and key switches for turning the fans on and off.

Using a wind-speed tester, Mike was able to determine that the inlet takes in air at about 0.6MPH, and the exhaust port pushes out air at 1.4MPH. However, it’s the center contraction section where the computer is that really benefits from the design, where the wind reaches 12MPH – or 9MPH with the computer in place. He actually was able to push wind speeds as high as 26-30MPH with the fan set on a higher setting. He even used smoke testing to ensure optimal airflow over the components.

Table Lamp with Charging Station or Power Strip with Bulb?

There are two ways to solve the problems posed by the short cables in gadget chargers – we can either get longer cables or get more accessible outlets. Etsy artist Jordan Waters makes the latter: a table lamp that’s equipped with USB ports as well as an AC outlet. I’d call it high-tech, but then it uses a conventional bulb as a light source.

You can order the lamp from Waters’ Boss Lamps Etsy shop. It comes in a variety of designs and has two versions: the single charging station pictured above sells for $95 (USD), while the dual charging station – which has a total of 4 USB ports and two outlets – sells for $125.

Giant LEGO NES Controller Works with Normal Size NES Consoles

How awesome is it that we live in a world with huge functional NES controllers? And those are just the ones we know about! Then there’s this one made by Baron Julius von Brunk, which is a bit geekier because it’s almost entirely made from LEGO.

The Baron connected the bricky buttons and the d-pad to small push buttons, which are in turn connected the circuit board of a NES controller. He built spring-loaded modules using Technic pieces to prevent the big LEGO buttons from getting stuck on the small push buttons.

Nintendo 64 Stuffed in Game Boy Player, Makes GameCube Backwards Compatible

Console modder Jon Jandran aka Hailrazer is back with another Nintendo related project. Instead of working on portable versions of old game consoles, Hailrazer decided to combine two consoles – the Nintendo 64 and its successor, the GameCube – into one playable unit.

nintendo 64 gamecube mod by hailrazer

Hailrazer crammed the guts of an N64 into the case of a Game Boy Player – the GameCube add-on that allowed GB or GBA cartridges to be played on TV. Because of space constraints, Hailrazer had to fold the N64′s cartridge slot, making it unusable. He loads N64 games on his frankenconsole using an SD card system based on the Everdrive 64 flash cart.

Hey Hailrazer, can you make an Xbox 360 that can also play PS3 games (or vice versa)? Head to Hailrazer’s thread on Bacteria’s Forum for more info on the hack.

Flying Superman: Best R/C Plane Ever?

Look up in the sky! It’s a bird… It’s a plane… It’s the geekiest R/C plane ever! You will believe a man can fly. This awesome Superman R/C plane makes if feel like Metropolis and makes observers do a double-take, wherever it flies.

superman rcAre they filming the new Superman movie with super cheap effects? Nah. Apparently a couple of guys were biking down the Pacific Coast Highway when all the sudden they see Superman fly by. WTF? Well, after some investigation, they caught up with the owner and shot some footage so that we all can see the awesomeness of this R/C plane.

Presumably, it’s one of these, just painted and caped up to look like the Man of Steel. I wish I had one, but I would just crash it on the first flight.

Cheap Wireless AirPlay Speaker Hack: Apple & Raspberry Pi

Tinkerers looking for a way to make their old speakers play nice with Apple’s AirPlay technology can now do so on the cheap, thanks to the Raspberry Pi, a neat hack made by Cambridge Engineering student Jordan Burgess and some free software.

The key component for Jordan’s hack is James Laird’s Shairport, an open source Airport Express emulator. Jordan also used the free Raspbian OS provided by the Raspberry Pi Foundation. Here’s the hack in action:

The tinny sound isn’t just YouTube’s compression; Jordan reminds us that the Raspberry Pi wasn’t built with audiophile level technology, so you might want to get a USB sound card as well. Head to Jordan’s website for more details on the hack. I’m still hoping the AirBridge gets produced.

Xbox 360 Bullet Buttons Get Lit up

I’ve already swapped out the buttons on one of my Xbox 360 controllerswith some bullet buttons, and they look cool. But now I’m really jealous because somebody is now selling a bullet button mod that actually lights up. Sweet.

DeadEye Modz takes actual 9mm brass bullet casings, drills out the centers, and mounts colored LEDs inside of them so you know which button is which by color, not just by touch like with other bullet mods. The installation process is pretty straightforward, but unlike other button mods, you’ll need basic soldering skills to attach the LEDs and resistors to the board to provide power. Instructions are provided, so if you’re reasonably handy, it shouldn’t be a big deal.

There’s also a matching, light-up Xbox Guide button – made from a shotgun shell – and available in a variety of LED colors of your choice.

A full set of LED bullet buttons is $20.99(USD) over on Etsy. The shotgun shell guide button sells for $12.99. And if you’ve got lots of money to burn and don’t feel like modding your own controller, you can always go for this fully-pimped-out customized controller for $259.99:
