Hackaday Prize Entry: FLipMouse

October 14, 2016 by 2 Comments

The theme of the last Hackaday Prize challenge was Assistive Technologies, and with this comes technical solutions for people with severe motor restriction. One of the best we’ve seen is a device designed to use a sip and puff interface and buttons to control a cursor through USB. The almost too clever name for a device meant to be used via fingers or lips is the FLipMouse, and right now it’s in the running for the finals in the Hackaday Prize.

The FLipMouse isn’t so much a mouse as it is a very long and very sensitive joystick. The main method of interaction is a long, hollow tube wrapped with force sensors. These force sensors, like those seen in the Nintendo Power Glove or this other Hackaday Prize entry, turn the tube into an exceptionally sensitive joystick, meant to be gripped by the user’s lips. This tube is hollow, too, so a sip-and-puff interface is used to register right and left clicks. Of course, there are a few external buttons that may be remapped to anything.

How useful is it? This mouth-based mouse seems to be exceptionally capable. In the video below, [Harry Hötzinger] plays a synthesizer live on stage using a step sequencer and a mouse-controlled synth interface. It’s all highly optimized for the specific piece of music, but it is an incredible display of what you can do with a laser cutter and a Digikey BOM.

Hackaday Prize Entry: A Cheap, Portable Incubator

October 13, 2016 by 23 Comments

Millions of premature babies are born every year, and more than a few of these births occur hours away from any hospital with a NICU. [Manoj]’s entry for the Hackaday Prize is a simple, but very useful primitive incubator. Is it as good as the incubators you would find in a world-class hospital? No, but that’s not the point. This is an incubator for the rest of the world, where neonatal care is lacking.

You’re not going to get mechanical respiration or even oxygen into a device that is meant for the most far-flung areas on the planet, so this incubator focuses almost solely on monitoring. Packed inside a premie-sized sleeping bag is enough electronics to measure heart rate, blood oxygen, temperature and respiration. Also, there are a few resistive fabric elements to turn electricity into warmth.

Of course, anything you would find in any hospital or clinic would greatly outclass what this project has to offer. That’s really not the point, though; this incubator is cheap, can be deployed anywhere, and provides enough information to hopefully keep a preterm child alive. That’s good enough for us, and makes for a great entry into the Hackaday Prize.

Hackaday Prize Entry: An Open Bluetooth Switch Interface

October 12, 2016 by 3 Comments

The theme of the last Hackaday Prize challenge was Assistive Technologies, and there is perhaps no assistive technology as desperately needed as a device to help people who can’t use common input devices. Using a keyboard, mouse, or touchscreen can be hard, but this Hackaday Prize project turns all these problems into a simple Bluetooth-enabled switch.

The BOSI – the Bluetooth Open Source Switch Interface – is, at its heart, just a big Bluetooth button inside a 3D-printed enclosure designed in Solidworks. These enclosures house a button connected to an Adafruit Bluefruit EZ-Key. Add a battery and a charging circuit, and you have a button that can be pressed by anyone, that connects to any device, and can do anything.

The real trick to a system like this is the software stack, and for this, BOSI can be used with iOS and OS X using the Switch Control interface. Android works, too, and the entire device is exceptionally usable for anyone that can’t use a normal input device. A great entry for the Hackaday Prize.

Hackaday Prize Entry: Hands|On Gloves Speaks Sign Language

October 11, 2016 by 7 Comments

The Hands|On glove looks like it’s a PowerGlove replacement, but it’s a lot more and a lot better. (Which is not to say that the Power Glove wasn’t cool. It was bad.) And it has to be — the task that it’s tackling isn’t playing stripped-down video games, but instead reading out loud the user’s sign-language gestures so that people who don’t understand sign can understand those who do.

The glove needs a lot of sensor data to accurately interpret the user’s gestures, and the Hands|On doesn’t disappoint. Multiple flex sensors are attached to each finger, so that the glove can tell which joints are bent. Some fingers have capacitive touch pads on them so that the glove can know when two fingers are touching each other, which is important in the US sign alphabet. Finally, the glove has a nine degree-of-freedom inertial measurement unit (IMU) so that it can keep track of pitch, yaw, and roll as well as the hand’s orientation.

In short, the glove takes in a lot of data. This data is cleaned up and analyzed in a Teensy 3.2 board, and sent off over Bluetooth to its final destination. There’s a lot of work done (and some still to be done) on the software side as well. Have a read through the project’s report (PDF) if you’re interested in support vector machines for sign classification.

Sign language is most deaf folks’ native language, and it’s a shame that the hearing community can’t understand it directly. Breaking down that barrier is a great idea, and it makes a great entry in the Hackaday Prize!

Hackaday Prize Entry: Augmented Reality Historical Reenactments

October 10, 2016 by 6 Comments

Go to a pier, boardwalk, the tip of Manhattan, or a battlefield, and you’ll see beautifully crafted coin operated binoculars. Drop a coin in, and you’ll see the Statue of Liberty, a container ship rolling coal, or a beautiful pasture that was once the site of terrific horrors. For just a quarter, these binoculars allow you to take in the sights, but simply by virtue of the location of where these machines are placed, you’re standing in the midsts of history. There’s so much more there. If only there was a way to experience that.

This is why [Ben Sax] is building the Perceptoscope. It’s a pair of augmented reality binoculars. Drop in a quarter, and you’ll be able to view the entirety of history for an area. Drop this in Battery Park, and you’ll be able to see the growth of Manhattan from New Amsterdam to the present day. Drop this in Gettysburg, and you’ll see a tiny town surrounded by farms become a horrorscape and turn back into a tiny town surrounded by a National Park.

This is a long term project, with any installations hopefully lasting for decades. That means these Perceptoscopes need to be tough, both in hardware and software. For the software, [Ben] is using WebVR, virtual reality rendering inside a browser. This means the electronics can just be a tablet that can be swapped in and out.

The hardware, though, isn’t as simple. This is going to be a device running in the rain, snow, and freezing weather for decades. Everything must be overbuilt, and already [Ben] has spent far too much time working on the bearing blocks.

Although this is an entry for The Hackaday Prize, it was ‘pulled out’, so to speak, to be a part of the Supplyframe DesignLab inaugural class. The DesignLab is a shop filled with the best tools you can imagine, and exists for only one goal: we’re getting the best designers in there to build cool stuff. The Perceptoscope has been the subject of a few videos coming out of the DesignLab, you can check those out below.

Hackaday Prize Entry: Raspberry Pi Zero Smart Glass

October 8, 2016 by 4 Comments

Some of the more interesting consumer hardware devices of recent years have been smart glasses. Devices like Google Glass or Snapchat Spectacles, eyewear incorporating a display and computing power to deliver information or provide augmented reality on an unobtrusive wearable platform.

Raspberry Pi Zero Smart Glass aims to provide an entry into this world, with image recognition and OCR text recognition in a pair of glasses courtesy of a Raspberry Pi Zero. Unusually though it does not take the display option of other devices of having a mirror or prism in the user’s field of view, instead it replaces the user’s entire field of view with a display and re-connects them to the world through the Raspberry Pi camera.

The display in question is an inexpensive set of “3D Virtual Stereo Digital Video glasses”, of the type that can be found fairly easily on your favourite auction site. They aren’t particularly high-resolution, but the Pi can easily drive them with its composite video output. The electronics and camera are mounted on a headband, in a custom 3D-printed enclosure. All files can be downloaded from the project page.

There is some Python software, but it’s fair to say that there is not a clear demo on the project page showing it working. However this is no reason to disregard this project, because even if its software has yet to achieve its full potential there is value elsewhere. The 3D-printed Raspberry Pi enclosure should be of use to many other similar wearable projects, and we’d almost say it’s worthy of a project all of its own.
