Well, there is JTAG available on all Atmegas bigger than the Atmega8 on the current Arduino boards. With JTAG you have breakpoints, run control and variable/memory watch. So this is possible, in principal (the Atmega128 on the wiring boards could allready do it)!
But you need a special JTAG programmer, too. And most important, the Arduino and Wiring IDEs lag JTAG support at the moment...

Hi,

well, the project is quite old (last update from 2003) and quite beta or gamma state...
But, imagine writing microcontroller programs in a nice & simple scripting language like python instead of C?
Do I see any geeks with glowing eyes now?
Ok, here you go:
http://www.python.org/pycon/papers/pymite/
It's called pymite and it needs 15kB of flash and 4 kB of RAM, so it's nothing for current arduino boards.
But an Atmega128, for what it's developed, gives plenty of playground space...

What are the thoughts of arduino developers on using a simpler language than C?

hi,

looks like I read this too late.
At least  I'm now downloading the streamdump of this talk...
Unfortunatelly, I'm leaving in a few hours.
Hint: you could also try to find wesen from http://ruinwesen.com/.
He gave a workshop about arduino based and algorithm created music.

Hi,

I'm there. Maybe we can meet at the microcontrollerworkshop or in the basement/hackcenter?

Oli

None at all.  I use subversion on both my Arduino directory and my eagle directory.  With a large project, or with multiple people, I would likely put one project with both hardware and software branches into one or two repositories, but just maintaining control of the Arduino and eagle directories works for my personal stuff (where I'm mostly concerned with having my various machines at work and at home synced up, less so with the revision history).

could you elaborate on svn with eagle usage?
My guess is, when you do an update, schematics and board layouts will be replaced as a whole, as they are binary files. Wouldn't the files get chopped otherwiese?

Shure there is file splitting e.g. as eagle libs, but as I understand eighthave, there is no way to split up a certain schematic or board layout in hierarchically consistent files. Thus, every sheet in an eagle schematic could represent an own file etc. This would be required for really collaborative work on an open hardware project.

Does anybode know how the internals of the open source schematic & layout projects gEDA/PCB (http://www.geda.seul.org/) would allow file versioning?

Well, BTW, there is now http://www.fritzing.org, als mellis annouced on the arduino blog: http://www.arduino.cc/blog/?p=11.
They hopefully consider a collaboration feature...

this is so great! be shure to watch the video:

I saw something similar developed by yamaha and shown at ars eletroncia 05: tenori-on
www.global.yamaha.com/design/tenori-on

yeah, but how exactly do they implement FTIR?
I'm pretty shure now, that it's just a beamer behind the screen and beneath that is camera to detect the finger movement. As massimo allready noted, there's no room light. I guess the contrast of the FTIR image would be too low in this case.

Yeah, I can't see how its working, too!
Especially because the emphasize that it's low-cost.
Well there is a sketch http://mrl.nyu.edu/~jhan/ftirsense/ but I have no clue how they detect the light. Is it just a row of light sensors on each border of the frame?
