Biological and Environmental feedback LED wristband #WearableWednesday

Thanks to Joseph for sharing his project with us! You can view more information on it here.

Our project is a LED Wristband that bases its light show on the user’s heart rate and the surrounding music. We are using an Arduino Uno and LED Strip combined with a mic to create emergent and dynamic color displays. We see this design as a way to supplement communication and create interesting group dynamics.

I know it is funny to say but the mood ring was ahead of it’s time. The ability to communicate mood is a fascinating idea. Putting this idea into practice by taking heart rate (your state) and music (context) we think a much richer experience can be shared via light. We are still prototyping but we have the basic sensors working to take in heart rate and sound and output those rates as lightshow on banded LED strips. We are also looking at possibly using bluetooth to your phone to control or manipulate your light output possibly giving some control via a networked phone app to the DJ (turning them into a light jockey (LJ)).

We want to create wearable lights that reflect where you are and your are experiencing. Imagine you are at a giant Skrillex EDM show at a festival like Lollapalooza. How ridiculously awesome if the audience contributed to and engaged with the music and each other in real time. Instead of fancy lasers and flames the fans are lit by their love of the music and the power of the music set.

Bluefruit EZ-Link – Bluetooth Serial Link & Arduino Programmer: We are excited to add another product to our growing Adafruit Bluefruit line, this time it’s the Bluefruit EZ-Link: the best Bluetooth Serial Link device ever made. Like you, we have purchased all sorts of Bluetooth serial link modules, with high expectations – we just wanted something that worked! But nothing ever did exactly what we wanted: there was always some configuration modes to wade through, and using one of those other modules to reprogram an Arduino is impossible.

So we did what we always do, we went in and engineered something better. Something that works! Read more.

Adafruit NeoPixel Digital RGB LED Strip – White 60 LED – 1m: You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticable strip color – this strip has white-colored flex PCB, which will be less visible against white-painted walls. This is the strip with white flex PCB, its identical to the black 60 LED/meter except it has a different color mask on the flex strip. Read more.
