steim makes 3 marching band electronic instrument based on linguistic characteristics of Limburg.
i used teensy2.0(usb full speed) as new interface for this project.
HID, 12 analog inputs, 10bit ADC, 10bit resolution, updating every 4ms

Tuba

3 pots and 1 air pressure sensor with instrumentational amplifier

Snare

3 piezo inputs(analog in)

Xilophone

12 piezo inputs(analog in)

Frank Balde programmed the sound using Junxion and Lisa

55		bye steim
55		thanks to steim, open source community and my mother...
54		Juggling Sound Ball silicone molding
54
53		Alex nowitz's left hand controller v.1.0
53
52		16channel piezo trigger(with teensy USB midi)
52
51		Alex nowitz's wireless controller firmware update
51		- higher priority to switches than other analog sensor datas- only send switch data when there's a change- shorter response time than key press in laptop (macbook 2.1)- switch encoding bug fix
50		drum trigger pad
50		- drum trigger pad using piezo polymer cable- (almost) evenly distributed trigger sensitivity on the large pad- 2 stage amplifier --> ADC- envelop length < 20ms.
49		4 wireless accelermeters and receiver
49		- 12 analog data inputs to junxion(3axis x 4)- 17ms. update rate- receiver stays connected as a arduino device when transmitters are off
48		wireless glove
48		for Freaka Geaka
47		Juggling Sound Ball v.1.8
47		- back to the linear VR // can't solve the noise problem- Xbee API mode, baudrate 115200 // disables wireless programming of AVR- ATMEGA328p // back in stock, to have more EEPROM space - it inhe...
46		wireless receiver v1.2
46		- ATmega328 16Mhz 5V// to have more array space(buffering) for incoming wireless data- D4(PD4) connects to tactile switch // configure mode- D5(PD5) connects to CTS(active low) pin of FTDI // for ha...
