I 've just installed ftdi hacked driver + roland serial driver + MIDI-OX (for those who need more info => http://www.megadrum.info/drivers.php) on my windows XP box.

I can hear a latency, did anyone of you experienced such a problem ?

@Ben : to remove the ftdi driver, download the FTClean from ftdi (windows only : http://www.ftdichip.com/Resources/Utilities/FTClean.zip).
Set 6001 for product ID and read carefully the dialog boxes (one time yes, one time no as far as I remember)

Just to say that the nuelectronics ethershield do not work with the Arduino NG (I think it is the same for NG rev C) because of the SPI pb.
I managed to get it working after applying this hack http://www.eng.uah.edu/~jdw/avr/arduino_r13_mod.jpg from this post http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1163734586.(the cmd resistor stayed stuck 10 seconds on my hot iron but seems to work perfectly) 8-)

Thanks kg4wsv !!!

Another pb : the ethershield do not initialize correctly without the USB plugged (the jumper is on ext power and is well plugged : strange...)

Nice
Where did you get the USB receptacle and how much did you pay for ?

ATtiny45 with 8 pins only is a good one too (2$ digikey).

In case you want a DIY DAC look at

It's a R2R ladder

Have a look at http://elm-chan.org/works/vp/report.html
First check if the component is still available.

I hope this will help

The Graphical User Interface is so nice to.
I like the way you exhibit your project (including price details)

I love the java knob to (and I hope Mellis 'll put many of them in the next arduino release :-)))

If you want a real 0008 version (if you are, as me, to lazy to configure avrdude for the 0009 alpha version) do

svn checkout svn://svn.berlios.de/arduino/tags/0008 instead of svn://svn.berlios.de/arduino/trunk.

@mrmeval : thanks for the step by step how to, it helps a lot.

FYI : I'm under Ubuntu FF

Hi CosineKitty,

I'll be glad if we can work together on it as I feel you have the same "open source spirit" as I have.
I'll be back home in 5 days, so don't expect to hear some news from me as I'm not connected (very hard for an arduino geek).

Is it possible to communicate with the computer from within an Arduino sketch?  Would the board still appear as a virtual serial port?  Would there be a way to create a version of the Arduino Serial functions that would work?  How many limitations would that impose on the other processing done by the sketch?

This is the main issue to solve. 2 solutions
 - Firmware side : AVR-USB CDC bootloader (see avrdoper for example).
 - Host side : a custom virtual com port

With Arduino 11 the serial pb will disappear (not tested yet but something like metaboard.upload.disable_flushing=true will solve the pb)

Tested. Yes this work.
I do not speak the metalab.at language, I don't know how to tell us to update instructions.

I'm working on this, those days.
Amazing work.

Since Arduino insists on having a serial line to upload the firmware (although none is needed for usbasp), you may have to edit Arduino's preferences.txt file manually and set the variable serial.port to an existing device. Preferences.txt is in ~/Library/Arduino on the Mac.
With Arduino 11 the serial pb will disappear (not tested yet but something like metaboard.upload.disable_flushing=true will solve the pb)

If you are running Linux like me you will have to set udev rule in order to allow the avrdude process to upload sketch (see http://forums.obdev.at/viewtopic.php?p=4436)
I think a timeout bootloader will be better than the jumper selectable boot mode.
Perhaps it will be better to rewrite completly the bootloader in order to have a CDC metaboard (but perhaps it will load to much the CPU).
This way you will be able to use serial.prints/reads to talk to the host
I'm sure il will be possible to make a simple arduino (able to program other avr, do a serial to usb converter, etc) at a very very low cost (10$ removing the external power regulator)

I never tried the boot-cloner.
But is it possible to use it with a Atmega8L target chip (as I can see on pictures) ?
