A Wearable Space Station Notifier

If you don’t live in northern Europe, Alaska, or the extreme southern part of South America, there’s a 400-ton, $150 Billion space station flying over your head several times a day. It’s the International Space Station, and it’s the most complex and expensive construction project of all time. Look up at the right time, and you can see a point of light rising in the sky, brighter than any star, darting across to the opposite horizon.

ISS-Above is a simple tool that will tell you when you’ll be able to see the ISS passing overhead next, and the creator of the project, [Liam Kennedy] has a new crowdfunding project to turn this space station notifier into a wearable. It’s called the Pulsar, and with the help of an RFduino and a real time clock, it will alert you to an upcoming station pass with a bit of wearable electronics.

The ISS-Above is a great device to keep tabs on the six astronauts currently orbiting our globe, but if you want to see the space station rise over the horizon… well, lugging a Raspi and an HDMI monitor outside isn’t the best solution. The Pulsar is a tiny wearable board with a ring of LEDs programmed with 50 future passes of the space station. When the station is overhead, the LEDs light up, and a bright object appears over the western horizon.

[Liam] brought his Pulsar to the most recent Hackaday Pasadena meetup, and as his wearable LEDs lit up, the ISS appeared right on cue. The evening was only tainted by a crazy lady who decided to argue the existence of the International Space Station.

Hat-Mounted Clock Requires Mirror For Wearer To Tell Time

[gfish] was planning on attending Burning Man and wanted to make something unique (and useful) to wear. He decided on a hat/clock hybrid. Just slapping a clock on a hat would be too easy, though. [gfish] wanted his hat to change time zones both via manual switches or physical location.

On the front of the hat there are 2 hands, as most clocks have. Each one is attached to one of two concentric shafts that run to the back of the hat. Each hand is individually controlled by an RC vehicle servo. Those of you familiar with RC servos know that a servos’ max rotation is about 180 degrees and is certainly not enough for a full revolution required by the clock. To fix this, there is a 3:1 gear set that allows a 120 degree rotation of the servo to move the clock hand a full 360 degrees. With this method, each hand can’t move past 12 and instead has to quickly move counter-clockwise to get where it needs to be in order to again start its journey around the clock face.

Mounted inside the hat there is an Arduino that controls the clock, a GPS shield to determine location and an RTC to maintain accurate time. Mounted on the side of the hat is a control panel that contains an overall on/off switch as well as a rotary switch for selecting a specific timezone or for engaging GPS mode. The whole thing is powered by a 9 volt battery.

A Haptic Bracelet for Physical Computing

[Tinkermax] has been reading about the Internet of Things and wearable computing and decided it was time for him to have a go at building a device that turned computing physical. The result is a vibrating wristband that connects his sense of touch to the Internet.

The electronics for this haptic wristband are a mix of old and new technology. The radio and microcontroller come from an ESP-8266 module that was programmed with [Mikhail Grigorev]’s unofficial SDK. The mechanics for the wrist-mounted computer consist of six pager motors mounted around the wrist. These are driven somewhat ingeniously by a TLC5917 LED driver chip. This meant the ESP would only need to use two of its GPIOs to control six motors.

Right now the software is simple enough; just a web page, a few buttons, and the ability to buzz any of the pager motors on the wrist band over the Internet. Now it’s just a question of making this wearable useful, but connecting each pager motor to different notifications – a new email, a new SMS, or some emergency on the Internet – should be pretty easy.

An OLED Ring for Bluetooth Notifications

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.

Making MicroView Wordy

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.

Cosplaying as HAL 9000

2001: A Space Odyssey is one of the greatest films of all time, but unlike every other masterpiece of SciFi, you’re not going find many people cosplaying as characters from the movie. Going as a monolith to a con would be hilarious, but [jacqueslelezard] had an even better idea in mind: a HAL 9000 costume.

The costume itself is just bits of painted cardboard, shiny material (we’d go with aluminum tape), some black mosquito netting to see out of, and in a stroke of brilliance, a tablet that will display HAL’s unblinking eye to con attendees. If you’re extraordinarily clever, it might be possible to sample lines from the movie and play them through the tablet. This is, unfortunately, the best way to replicate the voice of HAL, at least until someone gets the money to have [Douglas Rain] sit in for some voice work.

The only drawback to the costume is the propensity for the wearer to hit their head on doorways and low thresholds. This problem could be solved simply by increasing the size of the costume, but then you’re back in monolith territory. So, what do you want to be, a murderous computer or a galactic swiss army knife?
