Power Glove Takes Over Quadcopter Controls

Gerrit and I were scoping out the Intel booth at Bay Area Maker Faire and we ran into Nolan Moore who was showing of his work to mash together a Nintendo Power Glove with an AR Drone quadcopter. Not only did it work, but the booth had a netted cage which Nolan had all to himself to show off his work. Check the video clip below for that.

The control scheme is pretty sweet, hold your hand flat (palm toward the ground) to hover, make a fist and tilt it in any direction to affect pitch and roll, point a finger up or down to affect altitude, and point straight and twist your hand for yaw control. We were talking with Nolan about these controls it sounded sketchy, but the demo proves it’s quite responsive.

The guts of the Power Glove have been completely removed (that’s a fun project log to browse through too!) and two new boards designed and fabbed to replace them. He started off in Eagle but ended up switching to KiCAD before sending the designs out for fabrication. I really enjoy the footprints he made to use the stock buttons from the wrist portion of the glove.

A Teensy LC pulls everything together, reading from an IMU on the board installed over the back of the hand, as well as from the flex sensors to measure what your fingers are up to. It parses these gestures and passes appropriate commands to an ESP8266 module. The AR Drone 2.0 is WiFi controlled, letting the ESP8266 act as the controller.

Hackaday Links: March 1, 2015

The somewhat regular Hardware Developers Didactic Galactic was a few days ago in San Francisco. Here’s the video to prove it. Highlights include [James Whong] from Moooshimeter, the two-input multimeter, [Mark Garrison] from Saleae, and a half-dozen other people giving talks on how to develop hardware.

[Taylor] made a portable NES with a retron, a new-ish NES clone that somehow fits entirely in a glop top IC. The controllers sucked, but [Taylor] made a new one with touch sensors. All that was required was eight transistors. The enclosure is an Altoid tin, and everything works great.

Here’s a YouTube channel you should subscribe to: Ham College. The latest episode covers the history of radio receivers and a crystal radio demonstration. They’re also going through some of the Technical class question pool, providing the answers and justification for those answers.

[Prusa] just relaunched prusaprinters and he’s churning out new content for it. Up now is an interview with [Rick Nidata] and his awesome printed container ship.

The tip line is overflowing with ESP8266 breakout boards. Here’s the simplest one of them all. It’s a breadboard adapter with stickers on the pin headers. Turn that into a right-angle breadboard adapter, and you’ll really have something.

Here’s something that’s a bit old, but still great. [Dillon Markey], one of the stop-motion animators for Robot Chicken modified a Nintendo Power Glove for animation duties. It seems to work great, despite being so bad. Thanks [Nicholas] for the link.

[David] the Swede – a consummate remote control professional we’ve seen a few times before – just flew his tricopter in a mall so dead it has its own Wikipedia page. Awesome tricopter, awesome location, awesome video, although we have to wonder how a few really, really bright LEDs would make this video look.

Here’s an item from the tip line. [Mark] wrote in with an email, “Why do you put names in [square brackets] in the blog entries? Just curious.” The official, [Caleb]-era answer to that question is that sometimes people have bizarre names that just don’t work in text. Imagine the sentence, “[12VDC] connected the wires to the terminal” without brackets. The semi-official answer I give is, “because.”

Prototype LED Light Suit runs off of a NES Power Glove

[Greg’s] been playing around with wearable hacks for quite some time now, and he’s decided to add a new twist for his latest LED light suit (Mk 4) — An ancient NES Power Glove to control it.

He was inspired by the band Hypercrush who had a music video where one of the guys was wearing a laser-shooting power glove — awesome. Having already made light suits before, he thought it’d be fun to do something similar.

The suit is controlled by an Arduino Pro Mini which has been hacked into the Power Glove for ultimate button pushing capabilities. He’s using 5 meter LED strips of the classic WS2812  RGB variety, which allow for individual LEDs to be addressed using a single pin. It’s powered by a 5V 2A USB battery pack, and he’s made all the components very modular, you could even say it’s “plug and play”!

Axis Glove That Controls a Robot


This homemade glove and gesture controlled rover was created by [electro18]. It can send temperature, battery level, and object distance to the LCD panel on the wrist. Instead of a typical joystick, this wireless system taps into an embedded accelerometer to maneuver the robot like magic.

The main chassis platform is made of clear acrylic and has additional acrylic strips fixed to the edges for additional strength. A LM35 temperature sensor is wired to the front that monitors the environments that the rover explores. An HC-SR04 Ultrasonic Rangefinder acts as the eyes of the machine. The photodiode is covered with an adaptation of a 6mm heat shrink tube to avoid false readings. Once hooked up and turned on, the robot can be controlled with the futuristic power glove consisting of two parts. An accelerometer strap and a display strap are the biggest parts. The project shows that it is relatively easy to make a system like this. Other items like quadcopters and tiny water boats could be controlled with a similar type of setup.

A video of the axis glove maneuvering the vehicle on a slope can be seen after the break:

Flex Sensing for a DIY Data Glove


[Cyber] has been testing out intuitive input methods for virtual reality experiences that immerse the user further into the virtual world than archaic devices like a keyboard or mouse would allow. One of his biggest interests so far was the idea of a data glove that interacts with an Arduino Uno to interface with a PC. Since commercial products are yet to exist on a readily available level, [Cyber] decided to build his own.

He started out with a tiny inertial measurement unit called a Pololu MinIMU-9 v2 that tracks orientation of the 3-axis gyro and accelerometer. The USB interface was soldered into place connecting the wires to an Arduino Uno. From there, he hooked up a flex sensor from Spectra Symbol (which were supposedly used in the original Nintendo Power Gloves) and demoed the project by tracking the movement of one of his fingers. As the finger bent, the output printed on the serial monitor changed.

[Cyber] still needs to mount a glove on this system and construct a proper positional tracking method so that physical movement will be mirrored in a simulation.

[Cyber’s] day job has had him busy these last few months, which has forced the project into a temporary hold. Recently though, [Cyber] has been an active member and an influence in the local Orange County VR scene helping to build a nice development culture, so we’re hoping to see more updates from him soon.

To view what he has done up to this point, click the link at the top of the page, and check out the video after the break:

Commodore 64 Power Glove Is So Bad

The Nintendo Power Glove was terrible. Really, really terrible. Thanks to modern components, though, it’s possible to recreate the Power Glove experience in a way that doesn’t suck so much. That’s what [Leif] did with his motion sensing glove for the Commodore 64.

Instead of rolling his own IMU and putting it in a glove, [Leif] is using SonicWear SoMo, a glove originally designed to generate MIDI data for performance pieces. Inside this glove is a 9 DOF gyro/accelerometer/magnetometer, uC, battery, and XBee that can be easily reprogrammed to do something a little more (or less) useful than simply sending MIDI notes and commands.

[Leif] reprogrammed the XBees to use I/O line passing instead of sending serial data, and connected the recieving XBee to the C64 joystick port through a very simple circuit with a hex inverter.

All the code to turn a SonicWear glove into a C64 controller is available on the Github, and there’s a neat demo video of [Leif] demoing his glove at the VCF Midwest late last month.

Building optical flex sensors

[Joel] dug up this hack that he pulled off over ten years ago. It’s inspired by the Nintendo PowerGlove, and uses flex sensors to react to movements of your fingers. The interesting thing is, he built these optical flex sensors himself.

He likes to say that this is a ghetto fiber-optic setup. The inlaid diagram above gives you an idea of how the sensors work. An IR LED and infrared diode are positioned at either end of a piece of clear aquarium tubing. When the tube is flexed, the amount of light that makes it to the diode is diminished, a change that can be measured by a microcontroller. [Joel] found that he could increase the resolution of the sensor by adding something to the center of the tube, blocking the light when not straight. In this case he used pieces of scrap wire. The outside of the sensor was also wrapped in shrink tubing to keep ambient light from interfering with measurements.

He uses a trimpot to tune the sensors but we wonder how hard it would be to add a calibration algorithm to the firmware?
