Wearables are the next frontier of amateur electronics, and [Kevin]’s Arduboy ring is one of the best examples we’ve seen yet.
Inside the Arduboy is an nRF51822 – a chipset with Bluetooth Low Energy, an ARM Cortex M0,256k of Flash, and 16k of RAM. There’s also a an OLED and a touch button for displaying notifications from a phone, with the ability to reply to these notifications.
The enclosure for the ring is rather interesting. It’s a bit thick, but that’s for a reason – there’s a 40mAh battery stuffed along the sides of the ring. The enclosure itself is 3D printed to spec, and contrary to some beliefs, there’s nothing wrong with bending a LiPo cell once. Sure, it only has four hours of battery life with the display on, but it has a 24 hour battery life in standby mode, making it almost useful as an everyday wearable.
This is [Kevin]’s second wearable, the first being the Ardubracelet, an extremely interesting OLED bracelet with three different displays. The Arduboy is much more compact and comes extremely close to looking like a product. You can check out the video of it below.

Despite the MicroView shipping a ton of units, we haven’t seen many projects using this tiny Arduino and OLED display in a project. Never fear, because embedded systems engineer, podcaster, and Hackaday Prize judge [Elecia White] is here with a wearable build for this very small, very cool device.
The size and shape of the MicroView just cried out to be made into a ring, and for that, [Elicia] is using air-drying bendy polymer clay. To attach the clay to the MicroView, [Elecia] put some female headers in a breadboard, and molded the clay over them into a ring shape. It works, and although [Elecia] didn’t do anything too tricky with the headers and clay, there are some interesting things you could do running wires through the clay.
What does this ring do? It’s a Magic 8 Ball, a game of Pong controlled by an accelerometer, a word-of-the-day thing (with definitions), all stuffed into a
brass silicon, OLED, and clay knuckle. Video below.
If you’re wondering, Turbillion (n). A whirl; a vortex.

It’s always exciting to see the photos from High Altitude Ballooning (HAB) outings. While it’s no surprise that the Raspi is a popular choice—low cost, convenient USB jacks, etc.—this is the first build we’ve seen that uses an OLED during the trip to show real-time data on-screen to be picked up by the on-board webcam. (Though you may have to squint to see it at the bottom middle of the above image).
[Fabrice’s] payload made it to 26,000m, and the screen he chose, an ILSOFT OLED, performed admirably despite the extreme conditions suffered (temperatures can reach -50C). The last time we saw a near-space Raspi payload was a couple of years ago, when [Dave Akerman] was closing in on UK balloon altitude records. [Dave] hasn’t stopped launching balloons, either, testing new trackers and radio modules, as well as his most recent build that sent a Superman action figure to the skies—all recorded in glorious HD.
Check out both [Dave] and [Fabrice’s] blogs for loads of pictures documenting the latest in High Altitude Ballooning, and stay with us after the jump for a quick video of [Fabrice’s] OLED in action.

Here’s something that’s just a design study, but [Ivan]’s Apple IIe phone is a work of art. You’re not fitting a CRT in there, but someone out there has a 3D printer, an old LCD, and a GSM module. Make it happen. See also: the Frog Design Apple phone.
[Arduino Enigma] created a touchscreen Enigma machine. Why haven’t we seen an Arduino Colossus yet?
The crew at Adafruit now have a Flying Toaster OLED, which means we now have flying toaster bitmaps for all your OLED/graphic display projects.
[Ian] had an old rackmount programmable voltage standard. This was the remote programmable voltage standard, without front panel controls. No problem, just get an Arduino, shift register, and a few buttons. Video right here.
A few months ago, [Jan] released a neat device that stuffs a modelling synth inside a MIDI plug. He’s selling them now, and we’d love to see a few videos of this.
[Justin] tipped us about his slick custom OBD-II gauge that could easily pass for an OEM module. He was able to use the clock area of his Subaru BRZ to display a bunch of information including the oil and coolant temperatures and the battery voltage.
The forum post linked above has a good FAQ-based explanation of what he did, but so many people have told him to shut up and take their money that he created an Instructable for it. Basically, he’s got a Sparkfun OBD-II UART board communicating with a pro Trinket. The display is an Adafruit OLED, which he found to be an ideal choice for all the various and sundry light conditions inside the average car.
[Justin] was able to reuse the (H)our and (M)inute buttons and reassigned them to (H)igh to show the peak reading and (M)ode to, well, switch between modes. The (:00) now resets the peak readings. He offers suggestions for acquiring the specific CAN codes for your car to make the data more meaningful. [Justin]’s code is safe in the many tentacles of Octocat, and you can check out his demo video below.

While there is lots of hype about a big company launching a new wearable product, we’re more interested in [Walltech]’s open source OLED Smartwatch. This entry into The Hackaday Prize merges a collection of sensors and an OLED screen into a wearable device that talks to your smartphone over Bluetooth Low Energy.
The device is based on the IMUduino BTLE development board. This tiny Arduino clone packs an inertial measurement unit (IMU), a Nordic nRF8001 Bluetooth radio, and an ATMEGA32u4 microcontroller.
The 1.5″ OLED display comes from [miker] who makes an OLED module based on the SSD1351. A STP200M 3D pedometer provides activity monitoring in a tiny package.
On the hardware side, packaging all these components into something that will fit on your wrist is quite difficult. The prototype hardware is built from mostly off the shelf components, but still manages to be watch sized.
At this point, it looks like the code is the main challenge remaining. There’s a lot of functionality that could be implemented, and [Walltech] even mentions that it’s designed to be very customizable. It even supports Android; the Apple Watch can’t do that.
The project featured in this post is a quarterfinalist in The Hackaday Prize.
For [Tony]’s entry for The Hackaday Prize, he’s doing something we’ve all seen before – a head mounted display, connected to a Bluetooth module, displaying information from a smartphone. What we haven’t seen before is a cheap version of this tech, and a version of Google Glass that folds – you know, like every other pair of glasses on the planet – edges this project over from ‘interesting’ to ‘nearly practical’.
For the display, [Tony] is using a 0.96″ OLED connected to an Arduino Nano. This screen is directed into the wearer’s eye with a series of optics that, along with every other part of the frame, was 3D printed on a Solidoodle 2. The frame itself not only folds along the temples, but also along the bridge, making this HMD surprisingly compact when folded up.
Everything displayed on this head mounted display is controlled by either an Android phone or a Bluetooth connection to a desktop. Using relatively simple display means [Tony] is limited to text and extremely simple graphics, but this is more than enough for some very interesting applications; reading SMS messages and checking email is easy, and doesn’t overpower the ‘duino.
The project featured in this post is an entry in The Hackaday Prize. Build something awesome and win a trip to space or hundreds of other prizes.
