Beaglebone Black
The JS hardware underdog!
Some web devs think of robotics as impossible
1) "I don't know/like C/C++/BASIC"
In general, the implication that robots have a really steep learning curve.
HINT: I don't like those languages either, and if I can figure out robotics, so can you!
My Personal Mission
It is my personal mission to make sure web developers don't feel alienated by robotics.
I want to eliminate web devs saying: "I can't do robotics, I work in JS"
Disclaimer: I'm a huge fan of ALL the NodeBots.
What is the BeagleBone Black
$45
1gHz ARM Processor
512MB DDR3 RAM
2 gigs flash storage (expandable via MicroSD)
3D graphics accelerator
2x dedicated PRU
46 x 2 pin headers
What's different
SSH directly - no need for 2nd screen
Analog output pins x 8
Accessible PRU micro controllers
JS on the BeagleBone Black
JS is a first-class citizen
Node pre-installed
Cloud9 running on port 3000
Available libraries
Bonescript
Much more typical library, procedural, a bit bare-bones
Beaglebone-io
Reminiscent of johnny-five, evented, pretty new
Downsides of BeagleBone
A little hard to get ahold of
Community support in general not as prolific
(Though JS support compared to RPi is strong)
2) "But I don't know electronics!"
Electronics Lesson
What I know about electronics
Inputs: 3 wires - ground, input pin, power
(There might be a resistor in the power pin)
Outputs: 3 wires - ground, power, output pin
(Usually a resistor in the power or output pin)
That's it.
You now know just about everything I know.
How to get more information
Fritzing diagrams:
(Also the johnny-five repo has a seriously nice amount of diagrams/tutorials that are adaptable)
Demo Time!
What's next?
Angstrom -> Debian
(Better serial drivers selection, stability)
Beaglebone-IO being worked on
open-pixel-control being worked on
Take-Aways
You, too, can do robotics!
Build something, document it, and show it off!
Because excitement is contagious
Thanks for listening!
