Japan Google Developer Day

I’m getting ready to leave for Japan tomorrow for the Google Developer Day I am presenting at.  Should be some great fun!

I’ll keep this site updated with pictures and how things went.

Automated Photobooth

I made a photobooth for my brother’s wedding this next weekend.


 The user walks up to the Easy button, presses it and the camera takes 4 pictures.  Wirelessly, the EyeFi pro card transfers images over to the laptop and there is script running in the background to take the images in that directory and print them out with a wedding photo of Andrew and Jenn.

The whole thing takes about 1 minute and 30 seconds from press of the easy button to print out.  The guests get to keep a cool souvenir, then Andrew and Jenn get to have the pictures afterward stored on the computer.

If you want to get more technical, the script running on the computer is a simple python script looking for 4 images.  Hopefully, I’ll be able to just walk around the place, take 4 pictures, and have them automatically printed.  We will see.


This is basically what is inside the box.  Just replace the mic with the easy button.  There are a couple of transistors and resistors connecting the wires to the 2.5mm Canon Rebel jack.

Edit 8-5-2013: I should have posted code long long ago. Here it is.

Sourcecode for Arduino and Python printing code.

Arcade Fire Glowing Ball drop at Coachella 2011

Arcade Fire dropped these super cool balls from the sky at the end of the concert at Coachella last night. They were big beach balls that lit up and syncronized with each other. Soooo cool. I have one and took it apart.


Official Video (found another one and youtube takes it down):

My video from inside the ball pit:

This device made by ESKI Studio has 6 LEDs (3 on the front, 3 on the back), a MIC and it looks like IR receivers and transmitters, and powered by 2 9Volt batteries.  The microprocessor is an ATTINY84 chip.

On the circuit board is PixMob G2 “Summer into Dust” edition v. 1.3 03-2011

I’m looking for ways to turn my device back on, so if you know how, please let me know in the comments!

Arcade Fire is amazing!  These colored beach balls put a cherry on top of their already amazing concert

EDIT:  found a way to turn on the lights again.  Take the Mic, and touch the metal of it to the center line of Q2 for Green, Q3 for Blue and Q1 for Red. (Thanks Matt)

Higher quality pics:

I’m not sure what the device in between the 2nd layer and the clear plastic is.  I think its an IR receiver but I can’t find another one online that looks like it.

Update 4/18 10:27:  I tried playing back the Arcade Fire concert from Coachella’s video feed and nothing happened with the LEDs.

Update 4/19:  Seriously??  Some D-Bag is selling his on EBay for $999 + shipping.  This may be $30 in electronics and a $2 beach ball.
