Blink an LED the hard way

by on Nov.21, 2014, under Uncategorized

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.

Directional Speakers

by on Jan.25, 2013, under My gadgets

This speaker modulates audible sound on ultrasonic signal and send the modulated sound in a beam through the array of piezo speakers. The sound will be demodulated with the non-linearity of air itself and can be heard right in front of  the speaker. The case is made by laser-cut cherry wood. A small laser diode is used to indicate the path of sound. Full_Front[1] (continue reading…)

Branch Light

by on Jan.25, 2013, under My gadgets

assembled[1] Branch Light is designed as a new form of mood light. Normally mood light is a single light or a light strip that you can not change it’s shape easily. This modular mood light units use magnets to connect each other so they can be rearranged easily. It is ideal for decoration under table or on vertical surface like refrigerator. The magnetic connection provides mechanical, power and signal connetion. (continue reading…)

Inferential 3D Scanner with Goldfish

by 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. (continue reading…)
