Blink an LED the hard way

Here is an example of using Arduino Due’s usb host port. The USB device is also an Arduino so repeat this experiment will be easier. The Arduino Leonardo is running LUFA’s Generic HID demo. If you don’t want to set up toolchain for LUFA. There is a pre-compiled hex file for Leonardo. Please notice this demo will take over USB and you have to reset your Leonardo to enter bootloader again. The Due side code can be compiled and uploaded with Arduino 1.5.8 directly.

This is an updated version of flashlight on Google Glass. This flashlight get power and control signal from Glass’s micro-usb Port. A glassware can be voice activated to toggle the flashlight. However USB OTG (USB host) function requires root in XE11. More information on Github:

Some dll is needed in java/bin in processing’s application folder.
Inferential 3D Scanner with Goldfish
by seer on Oct.11, 2012, under Uncategorized
Project made for Kyle McDonald’s 3D Sensing and Visualization class, ITP Fall of 2012. By Deqing Sun and Tak Cheung.
This first class assignment, we were asked to build a 3D sensor from scratch. The concept came from brainstorming what devices are available to detect space. Off-the-shelf sensors like a laser range finders can gather distance and implementing this within a matrix we can create a set of 3D data. We thought sensory inputs are also inherent in every living organism too. There’s a lot we can do with that concept like putting a GPS collar on dogs. Using their travel paths to scan out pedestrian sidewalks over time. We chose goldfish as they’re conveniently swimming in a 3 dimensional medium and for their bright color it’ll be easy for our program/camera to pick them out.

Plinko Poetry is a new interface for electronic poetic expression by Deqing Sun and Inessah Selditz, two Master’s Candidate students at NYU’s Interactive Telecommunications Program. Drawing source text from current @nytimes and @FoxNews tweets, players can absurdly re-contextualize news headlines that are often overloaded with meaning. (continue reading…)
AVR Studio on Mac OS
by seer on Nov.11, 2011, under Uncategorized
AVR studio is the official development tool for AVR chips. Users can focus on programming rather than Makefile or configuring the tool chain. Also both the hardware and software simulation function is powerful and it is the only way for us to use the debugging tools to troubleshoot in real environment.
This is a tutorial of using PlayOnMac to run the AVR studio in Mac OS. The software functions pretty well. I haven’t tested the connection of the programming tools. (continue reading…)
