ATTiny wearable by Facelesstech

tl;dr It’s a foundation for a wearable platform. It’s a Nato watch strap threaded through a PCB with a coin cell battery holder between the PCB and the strap. I’m using a Attiny85 this time around but could be used for most chips/dev boards. This is a proof of concept to iron out any problems […]

Mary Etta West at SparkFun has remixed Anouk Wipprecht’s Kitty Ear project to make it react to audio:

Audio Reactive Wearables

At the beginning of this year I began prototyping an audio reactive headband to wear in my everyday life, like while dancing with my dog in my lab listening to Legend of Zelda dubstep.

 A few weeks ago I saw this post by my favorite Engineer/Maker/FashionTech Designer/Roboticist Anouk Wipprecht – a kitty ears soldering project with 3D-printed headband. I immediately ordered the Electronic Kitty Ears Headband from Shapeways, and after more digging around I found the Instructables tutorial for the kitty ears soldering project. The tutorial includes the BOM, the .stl files for the headband and a link to the OSHPARK shared project.

I downloaded the gerbers and exported the dimension layer as a gerber by itself. Then I imported it to the dimension layer in EagleCAD so I knew I had the same dimensions and my circuit would fit in the Kitty Ears headband. You can see the prototypes in the first picture. In a day I captured the schematic from the original prototype circuit and laid out the PCB design in the Kitty Ears form factor.

The design files and source code are available on GitHub:

Cyborg Ring

cordwood + smt + jewelry + blinkies + zinc-air batteries

This project evolved from Splinter, the SMT cordwood project I did last summer/fall. The ring is powered by tiny size 10 hearing aide batteries which should give 4-6 weeks of intermittent use, once I come up with a design that doesn’t break after a few days of wear and update the firmware to put the ATtinyx5 to sleep. The first rev (labelled ‘blink-ring’) used deep red 650nm LEDs. Searching for particular component lengths gave me an excuse to use strange 0508 resistors. And somehow, this is my first Charlieplexing project. Yaay novelty soldering!

Health-Monitoring Flexible Smartwatch

Hackaday Prize Entry: Health-Monitoring Flexible Smartwatch

[Nick Ames]’s Flexible Smartwatch project aims to create an Open Source smartwatch made out of a flexible, capacitive e-ink touchscreen that uses the whole surface of the band. This wraparound smartwatch displays information from the on-board pulse and blood oximetry sensor as well as the accelerometer and magnetometer, giving you a clear idea of how stressed…

Tilt activated LED watch

askoog89 saw a major flaw with many LED watches – you have to press a button to see the time:

A Watch

I tried fix that problem by using a tilt switch to active the LED showing the time when tilt your arm to look at the watch

The watch uses the low power MSP430G2211 MCU from Texas instruments to control the LED and mesure the time with the help of a 32kHz watch cristal. The MCU sleeps most of the time only waking up ones a second to count up the time and check if the tilt switch is active.  To show the time the watch uses 12 charlieplexed orange LEDs.
