Fun with GPUs and connecting with Arduino

For the first half of our evening Bob Free will be speaking and demoing some great things that we can do with iOS GPUs. From Bob:

Bob Free has been developing 3D software since the early 70's, founded Graphcomp in the early 80's and has been the VP of Engineering and CTO for a number of Bay Area start-ups. Bob founded POGL in 2007, a portable OpenGL open source project. He has been developing iOS apps since early 2008, and most recently worked for Apple as a senior face recognition researcher, filing several patents for machine vision, face detection and skin-tone innovations.

Bob will be talking about GPUs on iOS, beyond 3D rendering, and how they play a vital role in Edge Computing.
He will cover a brief history of GPUs, what they are, how they can be used, prototyping tools such as WebGL, pros & cons of OpenCL, and the future of GPUs.

In the second half, Scott Gustafson has organized a series of presentations on Arduino. From Scott:

Scott

Quick Intro to Arduino, IDE, derivatives (___duino), clones, variants (Teensy, Teensy++) [I'll have samples of all these]
Links on where to get Arduinos (Adafruit, Modern Devices, SeeedStudio, Dangerous Prototypes, Sparkfun, CanaKit)
Demo with Arduino temperature data collection over RF network
Demo with Arduino on Ethernet/wifi network as HTTP server
Demo RFID with Arduino

Differences between Arduino and Teensy, and why a Teensy is probably better for direct iPad connection (and possibly everything else...)
Direct connections: audio, USB (iPad only), Bluetooth (keyboard emulation only)
How to communicate between an iOS app and an Arduino (iOS side)
What should the Arduino do vs. what should the app do? Where does the logic go?
What the Made for iPhone rules are: Rule 1: don't talk.
How to do cool stuff with the SDK without hitting the app store rules: technical vs. policy restrictions
Demo: MIDI data logger

Use iPad control the home Electric light on/off. ( Android -> Bluetooth -> Arduino -> Electric light) Used iPad Controlled (R/C) car via Arduino ( iOS-> USB dock -> Arduino -> toy car )
