DIY CRT is fun, slightly dangerous, won’t lead to a home-made TV

DIY CRT

Looking for a DIY project with a bit more danger than an Arduino-powered TV muter, but don’t have the resources to start building a fusion reactor in your garage? Well, challenge yourself with this electron accelerator project that requires little more than a wine bottle, a vacuum pump, a neon sign transformer and a diode from a microwave oven. OK, so that’s not exactly a list of components you’re likely to have laying around, but they’re not terribly difficult to come by and at the end of the day you’ll have your very own, home-made cathode ray tube. That’s right, just like the one inside that TV you finally junked last week. You won’t be able to create your own old-school display with it, but you will be able to observe interesting effects like sputtering (a ring of metal ion deposits) and magnetic deflection. Check out the instructions at the source and the video after the break.

Netduino and WP7 used to remotely control sprinkler system, show off Microsoft’s DIY credentials

WP7 and Netduino controlled sprinkler

Arduino, Android and the iPhone usually get all the DIY love, but Mike Linnen, he has taken the road less traveled by — turning to Windows Phone 7, Azure and a Netduino Plus to get his home hacking on. The .NET-powered microcontroller is the heart of Linnen’s new sprinkler system which can be scheduled to turn on and off automatically or manually triggered remotely from his WP7 handset. The system also monitors weather forecasts and, if the chance of rain is above 39-percent, any sprinkler activity for the day is canceled to avoid over watering the grass and plants. It’s all pretty neat, and there’s some DOS command line action thrown in for good measure. Check out the lengthy demo video after the break, and hit up the source for more detail and the necessary code to set up your own.

Tacit sonar gauntlet gives the blind ultrasonic eyes (video)



Sure, your Arduino project can make a stuffed monkey dance, but is it really doing anything for the greater benefit of mankind? Okay, maybe — but not to the same degree as Grathio Labs’ Tacit glove, an Arduino powered sonar device that can help the vision impaired navigate foreign environments. This wrist-mounted gauntlet is comprised of an Arduino microcontroller, a few ultrasonic sensors, and a pair of servomotors to apply variable pressure to the user’s wrist to indicate their distance from an object or obstacle. Best of all, the gizmo’s circuit and software are registered under Creative Commons, which means you’re free to snag the plans from the source link below, and build your own. Go on, build one. Sure, it’s a lot of work, but would you rather rock a wrist-mounted sonar gun, or don an ear-tugging bicycle helmet? Your choice.

LED coffee table busts a multicolored move (video)

LED coffee table busts a multicolored move (video)

It might look like something out of MJ’s Billie Jean, but this colorful LED array won’t be under moonwalking foot — that is, unless the party gets crunk. This colorful grid is actually a table top, brought to you by way of TI’s MSP430 microcontroller, and it knows how to get down. The table is made up of 128 frosted glass cubes, each apparently capable of emitting 16 million colors. Its creators also produced a special beat-detection software, that could very easily have your furniture outshining the bumpers and grinders at your next party. If you’re looking for a little extra something from your coffee table, you can find full build instructions at the source link below.

Man builds DIY Segway for $434, begins casting ‘Arrested Development’ fan film (video)

This is Petter Forsberg. He’s just like you or me, with one important difference: he built his own Segway for €300 ($434). Granted, it doesn’t look quite as slick as Dean Kamen’s off-the-shelf self-balancing electric vehicle, but if the videos are to be believed (and there are plenty of hi-def ones to choose from), the two-wheeler moves pretty well, particularly when spinning atop old stone structures or beneath a Swedish flag. Forsberg has a breakdown of the project over on his page, which you can find in the source link — but be sure to check out the video below before heading over. It’s not the first DIY Segway we’ve seen, but darn if it doesn’t make us want to find some electric scooters to tear apart.

Mini Space Invaders arcade cabinet big on nostalgia, small in size

Always wanted an 80’s arcade cabinet for your living room, but the square footage in your studio apartment won’t cooperate with your gaming plans? Well, a master mini craftsman has created a seven-inch replica of Space Invaders that can fit on your desktop, coffee table, or bedside stand. It was cobbled together using the guts of a Game Boy Advance, some lilliputian controls, and a custom cabinet coated in shrunken decals that’s made of medium density fiberboard. Best of all, thanks to those Nintendo internals, there’s an entire arcade’s worth of games at your tiny fingertips. Between this and its diminutive Donkey Kong cousin, perhaps mini arcade cabinets are the future of gaming. Video of the little gem in action is after the break.

Gigabyte intros Llano-compatible A75 motherboards for the DIY set (video)

Llano-based PCs are still trickling their way into the market, but if you’re the enterprising type you can just up and build your own. Gigabyte just announced a family of seven A75 series of motherboards, all of which are compatible with AMD’s spankin’ new Fusion A6 and A8 chips and A75 chipsets. To recap, the Fusion A-Series combines a discrete-class Radeon HD GPU and either a dual- or quad-core CPU on the same die, though all of the A6 and A8 models are quad-core. These 35- and 45-watt chips are also stereoscopic 3D-capable and support USB 3.0, DirectX11, OpenCL / OpenGL, and both 1600MHz DDR3 memory and lower-power 1333MHz DDR3L memory. As for the motherboards, they allow for 108dB audio with 7.1 surround sound, and you can use Gigabyte’s Easy Tune 6 utility to realize Fusion’s promise of overclocking. They also use the company’s DualBIOS technology to prevent failure due to BIOS corruption, while each USB port has its own fuse to prevent port failure. Hit the source link for information on where to buy, and mosy on past the break for the full PR and a short demo video.

Web-controlled tweeting Roomba is a perfect storm of DIY magic

Web-controlled tweeting Roomba

There are three things that will guarantee your DIY project some attention: slap it on a Roomba, base it on Arduino, or make it tweet. Do all three and, well, you’ve got a nerdgasm-inducing bit of Make fodder. The creation you see above is a web-controlled tweeting Roomba whipped up by Instructables member matchlighter using a 500 series vacuum bot and the Sparkfun WiFly shield for Arduino. The autonomous cleaner can be triggered from anywhere there’s an internet connection and updates Twitter to keep you abreast of its status (Ahh! Dock sweet dock). While Mr. matchlighter was kind enough provide directions for building your own, a lot of the actual coding is left up to you. (We’re lazy, let us just copy and paste dammit!) If you think you’ve got the programming chops, hit up the source link for instructions and check out the original’s Twitter feed at the more coverage link.

Update: The complete code is in step eight of the Instructable.

Adorable CanBot chills in your fridge, quietly biding its time (video)


What’s the point of a robot disguised as a tank or, uh, a clothes dryer? If you really want to infiltrate human society, you need robots that can hide in plain sight. Thankfully for would-be robotic conquerors, Ron Tajima brings us the aptly named CanBot, which hides batteries, an embedded control board, and three RC-servo legs beneath its beer-can exterior. Tajimi controls it with a Wiimote, and in the video above you can see it walking and rolling. His son seems less than impressed, but he probably sees this stuff all the time. We’re mightily excited, and look forward to picking up a six pack. Of robots.

[Thanks, Robotbling]

CNC mill and Sixaxis controller make beautiful DIY music together (video)

CNC controlled by Sixaxis

Have you ever thought to yourself, “my CNC mill is pretty cool, but I really want to make it more awesomer”? Well, first, “awesomer” totally isn’t word, and second, have we got a hack for you! A reader wrote in to the DIY hub Adafruit to show off his CNC being operated by a PS3 Sixaxis controller — mimicking features found on high-end machines that allow you to trigger jobs from a distance and manually control the mill. Best of all, it’s a pretty simple mod that uses a program called QtsixA to map the gamepad as a keyboard and mouse, allowing you to interact with a Linux box running EMC2, which is used for controlling the mill, lathe, plasma torch, or a number of other fun and dangerous tools. Check out the video after the break.
