DIY Bluetooth Network Monitor: ISP Spy

There are many programs that track the speed and health of your Internet connection; many routers even have this functionality integrated in their admin page. But Zak Kemble wanted a way to check those stats at a glance without logging on anywhere or opening an application, so he made a small network monitor.

Zak used an ATmega328P microprocessor, a 1.8″ LCD, a Bluetooth module and a paper display holder to make the device. It gets its information from a Netgear DG834Gv3 router running OpenWRT. The router runs a shell script that obtains the data – which include upload and download speeds, ping, packet loss and even a clock and an email notifier – and sends it to a serial port. Finally a Bluetooth module attached to the serial port sends the date to the monitor. The monitor also has two display modes – the one pictured above and a simpler graphical display.

Another day, another tinkerer with an awesomely complex solution to a simple problem. Head to Zak’s website for his build guide.

How to Keep Water out of Any Canvas Bag

When it comes to bags and backpacks, the holy grail is a bag that’s completely waterproof, to protect all of your precious gadgets from rain and snow. Check out what Allen Mowery at DIY Photography has come up with. It’s an easy way to make any canvas bag water-resistant.

coating wax mixture

In order to make your canvas bag bead water, you’ll need two pots (or a double-boiler you don’t care about,) a mixture of paraffin and bee’s wax, and a brush. Water needs to be boiled in one pot. The other pot is going to be placed inside of this with the wax, causing it to melt. Use the brush to coat the bag with wax. Once you’ve covered the entire bag, let it dry. Toss it into an old pillowcase, and then tumble dry for 15 to 30 minutes. Once it’s done, you’ll have a water-resistant bag for a fraction of the price of an off-the-shelf one.

It’s also cool to just buy a cheap waterproof bag, but they are often less versatile and good looking as canvas bags. Waxing bags to keep water out isn’t anything new, and you’ll probably have to periodically refresh the wax coat as it wears, but it’s definitely a nice cheap way to keep your gear from getting soaked.

Mist Computer Display Spotted In Japan

mist screen Mist Computer Display Spotted In JapanYou know what they say, if you want something done, then you gotta do it yourself. Considering how it is rather dry in the Land of the Rising Sun during winter, it makes perfect sense to unpack that humidifier from time to time and keep things running nice and cool instead of being totally dry. In fact, a desktop humidifier became the inspiration for this budding inventor who decided to come up with a computer display that is made up of what else, but mist. It has become a custom to test out budding technology in Japan with Hatsune Miku, so the same applies here.

While the process is said to be extremely simple to conceive, it was nonetheless rather tricky to put together, and potentially impossible to perfect – which would be unfortunate for the world. The creator, who calls himself “shige-ruuu”, hacked into his desktop humidifier, where after that he hotwired it to pump out a thick volume of fog. A custom-built rectangular box will help disperse the mist evenly, where it is then mounted to the wall. Both box and humidifier are hooked up to a vacuum tube, where a projector is then set up behind the box in order to send the images from the computer.

X-Wing Coffee Table Is One For The Nerds

xwing table X Wing Coffee Table Is One For The NerdsForget about all of those expensive hand-carved, marble top coffee tables that are being sold at an overpriced figure at showrooms across the country, only to have a 80% discount slapped on it a month after you saved up a whole year for that coffee table. Here is something from Sean Regan and Aubrey Cohen, where it took a total of 6 months to carve it out. Touted to be extremely sturdy, it is a throwback to the Star Trek Enterprise tables that was previously done.

The top and bottom half which sandwich the glass have been bolted together, so that even if you accidentally bumped it while walking, it will still remain sure. The front comes with 3 points of support contact with the glass as well, so you can more or less say that it is well protected with enough “deflector shields” for real life bumps. Just how much does it cost? It is supposedly $14 an hour, which equals to roughly $60,500 – which is plain nuts, but considering how it is lovingly hand-crafted and pays a close resemblance to the actual X-Wing, who knows, someone might be crazy enough to stump up that kind of money.

Hidden iPhone Quick Draw Holder: Assassin’s Creed Japan

YouTuber morishowta is working on a wrist-mounted holder for his iPhone that quickly pushes the phone to his hand when he thrusts his arm forward. It’s like the hidden blade in Assassin’s Creed, or Travis Bickle’s gun in Taxi Driver, except it hides a smartphone.

But the gadget is just a small part of Mori’s video. His hilarious trial and error process and his other antics make his video even more worthwhile:

Here’s his follow-up to that video. It includes a newer model of his iPhone holder. He also tries to make one for his tablet. Guess how that works out.

Moshi moshi. I need to learn Japanese so I can appreciate Mori’s videos more.

IKEA Expedit Workstation Hack: Bibiophiles Rejoice!

I use IKEA Stolmen components as my library shelves, but this sweet setup makes me think that the Expedit series could be even more versatile. This convenient workstation was nested inside an Expedit bookshelf, allowing its owner to maximize the efficiency of his available space.

ikea expedit hack 1

Space was at a premium in Jason Outlaw’s one bedroom apartment. So he decided to use his Expedit as not only his bookshelf, but as his computer workstation and a TV stand. Jason added IKEA Non-Spotlights to add a bit of light, but the cooler, energy-efficient LED Dioders could work pretty well too. A slide-out Kensington keyboard holder fit his MacBook perfectly. Because of the depth of the shelves, his radio and receiver are hidden away behind books, and speakers are used as bookends. When not in use, the TV is covered up by a removable art panel.

It’s a cool hack, though I prefer large desks to allow my clutter to spread out.

Convert an Old Game Boy Into an Android Gamepad

If for some reason you still have an original Game Boy lying around, the time has surely come to throw it out—or, perhaps, convert it into an Android gamepad to relive that retro gaming feel. More »

Custom LED Glowing Borderlands 2 Zer0 Sword: My Her0 Zer0

Fans of Borderlands 2 would love to get their hands on this weapon. This awesome glowing sword is just like the one that Zer0 uses in the game – only this one is real. While there’s no cloaking ability to go along with this sword, it’s still pretty amazing.

borderlands 2 zero sword 2

This Borderlands 2 Zer0 Sword was built by Michelle Khuu (aka Sadistic-Otaku) out of wood, blue acrylic, a blue LED ribbon, a toggle switch and a 9v battery. It is a geek creation of deadly beauty. Hopefully she hasn’t cut anyone in half with it.

If she sold these, I would buy one. She would probably make a ton of money off of all us gaming geeks. At least we would look cool for the apocalypse.

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.

stun baton by pode coet

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.

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.
