Hi, Any chances that this would work in Windows XP also? Or is it just Linux stuff? -Mika >> On Mar 26, 2008, at 4:18 PM, Derek Holzer wrote: >> Martin Howse just posted his documentation of a simple HID sensor >> board, >> costing approx EUR 5 to make, which can be used over USB with PD, >> SuperCollider, etc. >> >> http://1010.co.uk/avrhid.html >> >> This board was used during a sensor workshop which took place at >> Pickled >> Feet in Berlin on 15 March 2008, with the second part taking place >> on 26 >> April 2008.

a crunchy noisy unpitched kind of affair
by nward04＠qub.ac.uk 27 Mar '08

27 Mar '08

Hi, Im being a bit lazy here but thought I'd ask in case anyone had a start on this. I need a patch to generate some sound. It will be controlled by just one potentiometer's position and velocity and must generate unpitched sound. So i guess I'll use the velocity to control amplitude and the position will control some other element related to timbre, or something. I was thinking of something like a sound of a sweeping brush or gravel being raked. Any quick patches or approaches to get me started would be great. thanks in advance Nicky

pdmtl [sample.play~]
by Daniel Wilcox 27 Mar '08

27 Mar '08

I'm using the pdmtl [sample.play~] within a wrapper in my patch library. On using it with drum samples, I get distortion if triggered rapidly ... which is a bit annoying. Think of the kick drum farting out on a crappy sub. I've noted this with the example samples that come with pdmtl as well. Am I getting this because it's assumed that I should be using [mix.out_~] which does some buffering? I need as close to realtime as possible and I don't run a gui, so I don't use it. The fault may just be with my samples and I could go and edit them ... but I have so many it would be a real pain. Oh well, I'm sure there will end up being some reason for me to implement my own sample player :P (hopefully not) -- Dan Wilcox danomatika www.robotcowboy.com

Performance with PD in NYC Tonight!
by Spencer Russell 27 Mar '08

27 Mar '08

Tonight is the Columbia Computer Music Center's monthly Fun Night! I'll be performing my sensor(and PD)-augmented double bass alongside drum psychopath Kevin Shea and bearded trombonist Ryan Snow. Also performing will be Jordan Paul on drums and electronics, and Victor Adan on dot matrix printer head. I also just put a recording up on the evil and ugly myspace of a recent improvisation I did on the same sensor-augmented bass(with slightly different PD patching) with George Lewis on trombone, Steven Lehman on alto sax and laptop, and Mario Diaz de Leon on electric guitar. It's the first track on there: http://www.myspace.com/spencermakesnoise I've got more info on the hardware I designed here: http://www.columbia.edu/~sfr2105

Yes - but the programmer circuit is even simpler (and the dev tools software is free). It's all described on the flightsim page referenced.. and there is a hex image there, tho I'm not sure on whether it was modified for the one described on 1010.co.uk. ... Actually, I think the 1010 circuit has a connector that you can connect to pins on a parallel cable for programming it in-place. Again, no warranties with these comments, I still haven't even started doing mine! -- http://myspace.com/haszari http://haszaristwocents.blogspot.com http://last.fm/music/Haszari ----- Original Message ---- From: Steffen Juul <stffn(a)dibidut.dk> To: Derek Holzer <derek(a)umatic.nl> Cc: pd-list(a)iem.at Sent: Thursday, 27 March, 2008 8:33:36 PM Subject: Re: [PD] [PD-announce] cheap AVR/HID sensor board Neat lill' thing.

One would need to (purchase parts to and) build a programmer first, right? Also, i can't find locate the code/hex-file on the website (http:// 1010.co.uk/avrhid.html). _______________________________________________ PD-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list Send instant messages to your online friends http://au.messenger.yahoo.com

chromakey range/value
by ian campbell 27 Mar '08

27 Mar '08

Hi I'm having trouble understanding how to give pix_chroma_key the colour I want to key out. Right now by playing with the value and range number inputs copied from the help patch gives me in effect a luma keyer. How can I key out a green screen? Here's the patch I have been building on.. I tried to hook up a colour picker from the mtl abstractions but it doesn't seem to do much. Uses pix_video from 2 pci capture cards. -- http//www.iancampbell.org

[Correct me if I'm wrong, I'm not too sure about this but] I think the USB-HID device is a lot faster/more responsive than the USB-serial interface used on Arduino. The advantage I see is that it's cheap, easy to build/understand, relatively responsive, and the you don't have to write or get a driver as it's a class compliant USB-joystick (i.e. semi-reliable folks like MS, Apple, linux do that for you). Though you do need to be able to interface with a joystick at software, but PD can do that with [hid] (?), and I believe there are other software utils to convert joystick motion to MIDI (aseqjoy ?). That's my limited understanding.. I haven't built mine yet :) have fun Rua HM. -- http://myspace.com/haszari http://haszaristwocents.blogspot.com http://last.fm/music/Haszari ----- Original Message ---- From: Derek Holzer <derek(a)umatic.nl> To: Hans-Christoph Steiner <hans(a)eds.org> Cc: pd-list(a)iem.at Sent: Thursday, 27 March, 2008 2:04:11 PM Subject: Re: [PD] [PD-announce] cheap AVR/HID sensor board I think Martin made this because he thought the Arduino was a bit overkill.

hello, gem library can`t load because look for a folder "openGL.framework" in my system....but my system don`t have this folder. I am using a powerbook G4 with OSX 10.4 (tiger) and the lastest version of pd extended (0.40.3) is my OS too old??? is something else? any idea? thanks a lot. with pd extended 0.39 gem was loaded without problem,but some objets dont`work(torus,muultiblob2,pix_fiducialtrack,etc) thanks again.

arduino and bluetooth
by Tim Boykett 26 Mar '08

26 Mar '08

Hi Arduinoids, I am using the arduino object with a normal (non bluetooth) Arduino board. When I start up, however, something (I think maybe the comport object) tries to connect with my phone (as a bluetooth device) and the PD patch with the arduino object will not appear until I have said Yes to the request for contact. Twice. This is annoying, to say the least. Does anybody have an idea how I can deal with this, other than having bluetooth turned off (which also only "sort of" worked)? Cheers, tim
