Don't know how to do what you want to do, just wanted to point out that this 32 channel servo controller board was mentioned a few days ago.

I'm sure there is an easier way, but maybe you can subtract 5V from your signal and amplify the resulting signal?

Dunno about the software part of your question. I guess you need to code the 1 wire protocol by hand.

They are obviously teaching at universities or similar institutions and order them for their students and classes. I doubt anyone orders 35 Arduinos for themselves.

> Ouch, wonder why such a large markup over pcbeurope?

Don't complain. Usually it's the other way round, we Yurpeens usually have to pay twice as much for our imported gadgets as you do.  smiley-razz
I guess the price will go down once they sold their first lot.

The Ravezooka is a musical weapon that shoots a wide range of powerful "hardcore" sounds based on your target's distance from the instrument.

Another Arduino project at Makezine:

6-pack - Arduino-based controller for live audio/video performances



"6-pack is an open-ended, highly customisable, and ultra-portable physical controller based on the Arduino board. 6-pack is an Arduino shield consisting of 6 linear potentiometer sliders that can be assigned to different variables in the user's preferred software. It can be used to control a wide array of audio/video applications, from software synthesizers to HDJ systems. All, with a minimal footprint (3,5" x 2,5") and on the cheap (just a fraction of the cost of an equivalent MIDI interface). The project is open source. Schematics and source code included."

Since Germany uses the PAL TV standard it might not work on NTSC equipment.

Very nice! Now I only need to find someone who is willing to do all this work for me. smiley-wink

I have the feeling that this is what eighthave is already doing with his Puredata/Firmata project.
Am I right?

Well, what I'd like to see in addition to the above is the functionality of the DataQ thing I mentioned earlier. A bunch of analog inputs so I can hook up all kinds of sensors, like for example variable resistors, industrial grade pressure transducers, temperature sensors, 4-20mA current loop and 0-5V devices, that kind of stuff.

The serial output could be something like this:
timestamp, analog in 0, analog in 1,... digital in 0, digital in 1, digital in 2, ...digital out 0, digital out 1, digital out 2...
