LED Matrix Handbag 2.0 – How To

Bag PicturesMy previous post describes a handbag containing a Twitter-connected LED matrix.  The project was somewhat complicated to assemble – particularly the handbag sewing and construction.  This post describes a simpler and more practical way to incorporate an LED matrix into a handbag.  I’ve made several different versions of this project now, involving different styles of handbag.  The version described here produces a vinyl tote bag with contrasting accent fabric as seen above.

LED Matrix Handbag 2.0 – Coming Soon

I recently made a simpler and more attractive version of the LED Matrix Handbag to bring to the Bay Area Maker Faire.  It is far easier to sew than the original, with more streamlined and compact electronics.    Hackaday spoke to me at the Maker Faire about the handbag, and published the interview. If you’re interested in making one yourself, I plan to have a project write-up finished within the next few weeks as soon as I can get to it.  It’s here!  In the meantime, here are some pictures and footage of the latest LED Handbag:

My goal with this project was to create a wearable electronics project that incorporated the electronics in an organic and subtle way.  The end result is a handbag containing a programmable 10×6 LED matrix hidden inside the lining, with the LEDs visible from behind metal eyelets.  The LED matrix is controlled by a Teensy 3.2,which connects to an iPhone via an Adafruit BlueFruit BLE UART Friend.  The Adafruit Bluefruit App on the iPhone subscribes to a MQTT feed (from Adafruit.io in this case), which streams data culled from Twitter via IFTTT.  Any tweets with the hashtag “#wearables” have their Twitter handle displayed on the handbag’s LED  matrix.  Video demonstration below:
