Speakjet demo mode
The first step of my talking robot project – test whether this Speakjet chip works! Strangely, I couldn’t find much help on rigging up the demo/ test mode for the chip so here it is. I used a AA battery pack to power the breadboard and an LM386N op amp to hookup an 8? speaker to get sound out of the chip. The chip circuit is the demo circuit on the Speakjet datasheet and op amp circuit is the gain=20 circuit from the op amp datasheet.

Testing the Wave Shield
Testing the audio Wave Shield from adafruit. It took a while to get it working because strangely the USB cables I got from Staples don’t work with it. Very weird. Anyway here’s the first test with the looped audio example.

Jnx prototypes v0.0
Some initial prototypes for jnx the stress doll.
Look and feel
Materials:
Implementation
4 Flex sensors, a force sensor and an RGB LED. The LED changes color depending on how much pressure is applied to the force sensor or how much the flex sensors are bent – I still need to work this out in the code. Currently, the mp3′s are triggered from the computer using Processing but eventually they will be triggered from the SD card on the Wave Shield.

Runes of Magic vs Facebook
Comparing and contrasting an MMORPG and a virtual community. This presentation and attached paper analyze and compare the social and other features of Runes of Magic and Facebook with a view to identify what works, what doesn’t and they could learn from each other.

Diver: Sequencer on acid!

An Arduino sound project, Diver is an instrument inspired by old Analog Sequencers and Theremins. It allows creating a four-note looped melody which can be manipulated in real-time with knobs that can assign upto 5 octaves for each note. Each knob lights up to indicate it’s position in the loop.
The top of Diver houses a sensor which can be used to control the tempo of the loop in real-time. Use Diver in live performances or at home to produce awesome loops, melodies and special effects.

Theremin like instrument: Prototype 2
Second prototype for the theremin style instrument. It is more of a sequencer now with 4 POT’s for changing frequencies in a looped melody and a sensor changing the tempo.

Theremin like instrument
This is the first implementation prototype of an instrument inspired by a theremin. The POT changes the frequency and the sensor adds another frequency to the mix. The idea is to create a theremin and an analog sequencer hybrid. I want to add 4 potentiometers to generate a looping melody and using the sensor to alter or add to it.
