Take To The Skies With This Flying RC Superhero

July 5, 2011 by Mike Nathan 42 Comments

It’s a bird! It’s a plane! It’s….

A flying RC super hero?

No, you’re not imagining things. Maker [Greg Tanous] loves both RC airplanes and super heroes, so he thought it would be awesome to combine his two loves into one spectacular toy. The RCSuperhero comes in two flavors, measuring 75″ and 57″ tall. The larger plane can be purchased as a kit, but the smaller unit is only available in plan form.

The flying superhero weighs in at just about three pounds, and is constructed from foam, carbon fiber, and various other lightweight materials. When using the recommended motor, the RCSuperhero can be launched from a standing position, doing away with the need for runways. The craft looks to be just as maneuverable as any regular RC airplane, making it easy for any seasoned pilot to pick up the controls and get started.

RC planes are pretty cool, but we’ve got to admit that the idea of a vertically launching, flying superhero sounds like a lot of fun!

Stick around to see [Greg’s] RCSuperhero in action.

Kinect-controlled Quadrotor

The team over at the Flying Machine Arena has been busy combining two of our favorite toys – quadrotors and Kinect.

Like many other hacks, they are using Kinect to monitor their joint positions, mapping a handful of actions to the operator’s movements. Once the quadrotor is aloft, it can be directed around the room using the operator’s right hand. The gesture recognition system responds almost instantly, guiding the vehicle in all directions with ease. When the user’s left hand is raised, the quadrotor does a mid-air flip and awaits its next command, while a quick clap of the hands brings the machine to rest on the ground.

For the protection of anyone testing out the system, overhead motion tracking cameras are used to keep track of the Kinect’s position, creating an invisible midair barrier through which the quadrotor is not allowed to pass.

If you have a minute, check out the video below – controlling quadrotors looks way more fun than any Kinect game we’ve come across.

Voice Controlled Robot Controlled By An Android Phone

July 5, 2011 by Brian Benchoff 2 Comments

[Jeff] sent in a build of a voice controlled robot he just finished based on the Android ADK and an iRobot Create.

The robot is able to obey voice commands telling it where to go. Currently the robot responds to forward, reverse, left, right, stop, and ‘whistle while you work.’ It’s a creative use of the Android ADK with some obvious applications, but this project really shines with the write up on instructables. It’s rare that we’ve seen a project so well documented; it’s a great project for someone who wants to get their feet wet in the world of robotics.

[Jeff]’s write up goes through the steps of hooking up the ADK board to iRobot and providing all the electronic necessities. [Jeff] graciously provided the code for his robot if anyone would like to add to his project.

The ultimate goal [Jeff] is currently working towards is something akin to a TurtleBot, while keeping the voice control of the robot. In all, a very nice project.

Augmented Reality Game Could Come From The Seventies

July 5, 2011 by Brian Benchoff 19 Comments

[Niklas Roy] sent in a project he just completed called PING! Augmented Pixel. At first glance the entire build is just a plain jane retro video game stuffed into an ATmega8 but looks can be deceiving. The video game is actually an augmented reality device that inserts a pixel into a video feed. The bouncing pixel can be manipulated with a camera – push the pixel and it goes off in another direction.

The project runs on an ATmega8 clocked at 16 MHz, and reads the video feed with the help of an LM1881 sync separator. There’s no schematics, but he thankfully included some code for his project. Everything is set up for PAL video, but this could be easily adapted for NTSC. Any Hack A Day readers want to take up the challenge of building this from just a description?

[Niklas] says there’s no reason this couldn’t have been done by Atari in the late seventies. There were economic reasons for not putting out a video camera controller, of course, and the R&D department may have been too busy playing Breakout with their eyebrows.

Check out the demo of the augmented pixel after the break.

Fog Horn Built From Plumbing Supplies

Instructables user [rog8811] was looking to build a fog horn that resembled hand-pumped units found on small ships in the early to mid 1900s. His budget was a bit limited, so he set off to build the cheapest replica possible.

While the original horns were likely constructed from steel, copper and wood, he opted to use cheap plumbing components he found at his local hardware store. He used a simple double-acting air pump to drive the horn, combining it with a slightly modified bottle trap. The trap was shortened, and a diaphragm cut from a dish washing glove was added to generate sound.

He added a few more pieces of PVC piping to enhance the output, giving him the results you see in the video below. He says that the best thing about his design is the ability to easily tweak the pitch and volume of the horn by simply adding different drain components to the pump.

Watch out vuvuzela, there’s a new cheap and annoying horn on the block!

Alarm Clock Forces You To Play Tetris To Prove You Are Awake

July 4, 2011 by Mike Nathan 28 Comments

Oversleeping sucks, but we’ve all been there. Whether its a matter of hitting the snooze button a dozen times too many, or turning off the alarm and drifting back to sleep – sooner or later, you are going to wake up late.

Instructables user [nolte919] has overslept a time or two in his life, and he set out to design a clock that would make it nearly impossible to wake up late. His clock is Arduino-based and shares many features with off the shelf models including multiple alarms, a backup battery, and snooze features. His alarm however goes one step further and ensures you are fully awake each morning.

If you hit the user-defined snooze limit, the alarm sounds and will not turn off until you have cleared 4 lines in Tetris. That’s right, you have to prove to the clock that you are awake and coherent before it will shut off. Technically you can silence the alarm for a 30 second period so you can focus on Tetris, but that’s all the break you get.

It really is a novel way of ensuring you are awake in the morning, and heck, how bad can the day be when you start off by playing video games for a few minutes?

Stick around to see a quick video of his Tetris alarm clock in action.

CEE Is A Swiss Army Knife For Analog Electronics

July 4, 2011 by Brian Benchoff 28 Comments

The team at nonolith labs announced their CEE, a device for billed as, “an analog buspirate” that is meant to control, experiment, and explore the world of analog electronics. Nonolith labs started a kickstarter campaign for the CEE.

The CEE is capable of sub-millivolt and milliamp sampling at 44.1k samples/second, and sourcing 2 channels of 5V @ 2A with a little bit of soldering. This allows for precise control of motors and sensors with the web-based UI. We’re thinking this would be a great way to teach high schoolers the art of electronics, and would be great combined with a few lectures from Paul Horowitz.

The CEE ties into nonolith labs Pixelpulse, a pretty handy tool for visualizing analog and digital signals. You can check out a demo of Pixelpulse simulating a charging capacitor here.

We’re hoping this focus on education on analog electronics catches on – you can learn a lot more by building a 555-based mini Segway than you can slapping a microcontroller in every project. This would go under the same theory as, “any idiot can count to one.”

Check out the video of the CEE on the kickstarter campaign page.
