LED Shades Launch: Maker Faire Bay Area 2013

Maker Faire Bay Area 2013 was my seventh Maker Faire as an exhibitor, and macetech's fifth year. No matter how many times we go, we are never prepared for the huge amount of creativity and curiosity crammed into every inch of the fairgrounds.

This year, we launched the LED Shades that we've been working on for quite some time. We demonstrated a prototype last year at Maker Faire, and due to all the other projects we've been doing, it took quite a while to finalize the design to a point we felt comfortable selling them.

Here's the final product:

They're constructed with 3D printed hinges and removable cables, an integrated Lithium-Polymer 400mAh battery, and an Arduino-compatible controller built into the right side. There's a USB mini-B connector to both download new pattern code and charge the battery from any USB port. The 4-layer front PCB contains 166 bright LEDs arranged in a 24x8 matrix (with some pixels absent to follow the shape of the glasses). Solder pads are available for some of the unused Arduino I/O pins, to allow you to hack the shades with your own extra hardware. The code for the LED Shades is available at the bottom of this page: LED Shades

Every LED on the front is individually addressable, and each LED can be set to 256 different brightness levels. Additionally, the entire LED matrix can be dimmed or brightened 256 levels without affecting the overall brightness resolution for individual pixels. There is a light sensor to allow automatic brightness control, or possibly communication with other devices.

The hinges, nose pad, and battery box are all 3D printed. The hinges and nose pad are made from 618 nylon, for the best strength and flexibility available in 3D printed parts today. We're still working on fine tuning the design, as they fit most faces well but not quite all. However, we'll release the 3D files and also help out with any problems getting them to fit securely. A lanyard is still a really good idea, because you don't want to drop these.

Production overran our expected costs by a lot, especially for our first run...so we had to price a little higher than we initially hoped. At Maker Faire we launched with introductory pricing of $160. At that pricing, we sold out of our first production run! We had a computer running the Arduino IDE and helped each customer put whatever text messages they wanted on the shades.

The Maker Faire crowd absolutely loved our LED Shades, and as always were overflowing with great ideas, advice, praise, and criticism...all welcome! This is why we always go overboard building out our booth, although it crowds out our garage space for a few weeks.

This year, we used the ShopBot at TechShop in Menlo Park to cut a giant set of LED Shades out of plywood. Then we used some WS2811-based pixel strings to light each of the 166 LED locations. The giant shades were controlled using Processing on a laptop, through a PJRC Teensy 3.0. We brought back 2/3rds of the circular LED kiosk from last year, lit with Satellite S-001 modules and OctoBars.

Exhibiting at Maker Faire is physically and mentally exhausting. Every year we believe that we'll somehow take shifts and let people go out and see the rest of the Faire, but we end up having to stay in the booth even more. Many thanks to our friends who helped set up, answer questions, let people try on LED Shades, and brought us food: Matt, Graham, Ethan, Karly, Adrian, Arch, Nio, Nazak, and more!!

We discovered that they sort of work with Google Glass:

And they look absolutely smashing with a fancy RGB LED vest:

That's a wrap for Maker Faire 2013. We'll be at Maker Faire NYC (as attendees only!) but will keep working on the LED Shades and other exciting new devices. We're putting together some more LED Shades and will have them in our store soon! Thanks everyone who stopped by!

I THE GUYS THAT TOOK HOME THE ONES THAT READ "EVEN KANYE IS JEALOUS" & "I'M BIG IN JAPAN" LOL ANY WAY I'V BEEN TRYING TO CHANGE THE WORDING ON THESE BAD BOYS AS COOL AS THEY MAY BE NOW TO SOMETHING DIFFERENT. HOW OR WHERE ONLINE CAN I GET INFO TO HELP ME WITH THIS? I HAVE A MAC BOOK PRO IF THIS HELPS TO FINDING THE BEST WAY TO SEARCH FOR A COMPATIBLE PROGRAM OR SITE. THANKS AGAIN GUYS AND HOPE TO HEAR FROM SOMEONE SOON
