Oh Makers Fair!  I think I am returning next year :)
+Jason Coon and I met SmartMatrix contributor +Konstantin Gredeskoul at Maker Faire! It was great to meet SmartMatrix contributors and users, and see other peoples projects.

Take care of that finger Konstantin!

Quick question: I was dumb enough to accidentaly plug in 12V power into SmartMatrix + Teensy.  The Teensy board is fried, and it looks like even with another Teensy board the matrix is not working.  I am attaching a video of what it looks like with a fresh/new Teensy board, flushed with the latest trunk of Aurora code, and connected to 5V.

Any pointers?  Is this the matrix itself?  Is it the SmartMatrix board? Something else?

I am using external power adapter, and not the USB.

Another finished project: bed side clock with neo pixels, light sensor, and seven segment LED screen from Adafruit. It's running on Teensy, which is an overkill, but I kept having issues with my Pro Mini and ran out of time :) It was made as a present for a friend.

I am particularly happy about the laser-cut enclosure, where for the first time I used matte acrylic. Front panel is split into three sections, with the middle one being transparent black that darkens the LEDs, and looks cool :) This is a pretty compact enclosure, measuring 5.2" wide, 1.2" deep, and 2.2" too (the inner box is only 1.8") on the outside. I had to get creative to fit all the parts in, the way I prefer: using cable joints and not soldering any expensive parts to any boards (so that I can replace them easily).  

You can read about how the rotary knob is used and much more on the project github page below.

Thanks! :)

A great company where I work, Wanelo, with all of it's 35 people, recently moved to a new office which has only two single-occupancy bathrooms, each on a separate floor.

Anytime you'd need to use a restroom, you'd to the downstairs bathroom only to find its door locked. You'd then run upstairs and find the other one locked too... Damn!  Run back down only find out that someone else grabbed the first bathroom while you were upstairs. Argh!

You can likely see how this could be a frustrating and disruptive experience even just once or twice. Now multiply that by 35 employees and every work day of the year, and you end up with an actual productivity problem.

To solve this problem, I got approved for a small budget of about $200, and started digging. The result is the project called BORAT :)

"FilxCapacitor" - Music Box / Lights Show / Photo Slide Show / Clock

This box was created as a present for a dear friend at the time of need, and the idea was to create a bed-side clock that can additionally function as a mesmerizing media box, with some uplifting music and photos collected from friends.

Project source code: https://github.com/kigster/FilxCapacitor

Inside, it is powered by Teensy 3.1 with an Audio Shield, two 3W speakers and a small digital amplifier, 4 Adafruit NeoPixels, a Joystick to control photo show and tracks, as well as the rotary encoder on the top to control music volume, or to help set the time in the Time Set mode. 

Audio shield was supplied with a 16GB high throughput SD card, which contained both pictures (in BMP format) and audio files (as WAV), and Teensy was able to playback the files while at the same time reading another file for display!  Pretty awesome. 320x240 TFT display did a great job at keeping color accurate and very bright.  Although to control backlit display brightness I chose to use an adjustment potentiometer, so that I could tweak it after the assembly.

As the box's main and unexciting mode is to be a bedside clock, amber LED display (also from Adafruit) was used to show the current time.  For Teensy to be able to sync the time, a crystal was soldered onto the bottom, and a 3.3V backup battery supplied.

Overall this is probably the most complex project I've ever done with Arduino compatible hardware, and the codebase, when converted to hex used up about 30% of Teensy's enormous memory buffer.

Anyway, this is my first project video, and hope you enjoyed watching it!  Please leave comments if so :)
