DESCRIPTION
Sparky Jr. is a programmable RGB LED mod companion light-up activation controller for arcade pushbuttons. 2 parts software, 1 part hardware, the Sparky Jr. is a unique interface and an extendable platform with a unique combination of Arduino, Processing and RGB LEDs. Eugene Andruszczenko (32teeth) walks us through the ideation, creation and realization of leveraging OpenSource Hardware and Software through to product development. Presented at FITC Toronto 2014 on April 27-29, 2014 More info at www.FITC.ca

what is the SparkyJr.

what is the SparkyJr. the backstory
a few years ago…
i joined a fightclub
i got myself a fightstick
i got myself a fightstick i met some people with ideas
the birth of an open source product
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
SparkyJr. a programmable RGB LED mod companion light up activation controller for arcade pushbuttons on gaming fightsticks
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
SparkyJr. built on an open source microcontroller standard.
interlude
a challenge has entered the ring
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
challenge. low barriers to participation keep costs low (under $25) core hardware only shift registers LED driver IC simple interface for non tech savvy folk open source FTW!
cont(str)ain yourself
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
limits. atmega328[p][au][nd] only has 20 I/O 6 of which are PWM common arcade controllers have 8 face buttons 8 RGB LEDs = 24 lines (1 common, 1 per color) that’s 32 lines 12 more than we have [facepalm] this was our "'oh sh1t" moment this was our "awwwwwww sh111111111t" moment
work with what you have
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
approach. 8 I/O for button inputs multiplex the rest
8 I/O for LED common line (anode/cathode) 3 I/O for colors (red, green, blue) row column scanning… …really really fast (no flicker)
port manipulation faster than digitalWrite hello timers aka TCCR (Timer/Counter Control Register)
TCCR0B = TCCR0B & 0b1111000 | 0x01; millis() and delay() TCCR1B = TCCR1B & 0b1111000 | 0x01; TCCR2B = TCCR2B & 0b1111000 | 0x01;
PORTD = B1010010

The image cannot be displayed. Your computer may not have enough memory to open the image, or the image may have been corrupted. Restart your computer, and then open the file again. If the red x still appears, you may have to delete the image and then insert it again.

milestones
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
official Launch. the first commercial version was pre programmed to the users specified configuration using the purchase order form Made to order!
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
stay open. the first commercial version had an FTDI pinout for advanced users to reset, reprogram, hack. Great Results!

round 2. the second generation introduced a downloadable configurator, built in Processing, exported as a Java application.
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
shared. the second generation spawned a collaborative project with two web stores dedicated to fighting game hardware and parts
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
round 3. the third generation release was a collaboration with the web stores, under license to manufacture and distribute under their brands
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
help desk. end user support became a full time job (almost)
a long hiatus
a brief hiatus
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
silence is broken. in november of twenty thirteen, i joined createInTO and met rick mason
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
round 4. the quietly release fourth generation was showcased incorporated with the third generation configurator
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
reboot. taking the hardware back to the arduino uno r3 no gimmicks
SparkyJr. RGB LED Controller 32teeth eugeneyevhen 32teeth.github.io in/32teeth
rebuild. both the core SparkyJr. software and configurator where revisited from received feedback, rebuilt, and optimized
demo time!
