arduino melody example in PD?
by altern 08 Nov '09

08 Nov '09

hi i have been trying to port this example to PD http://arduino.cc/en/Tutorial/Melody it just uses a piezo to buzz a song. i dont understand very well this PWM controls and also I am finding quite difficult to translate the arduino code to PD. So after some headache i thought maybe someone has already done this for PD? thanks enrike

list-shuffle
by Matt Barber 07 Nov '09

07 Nov '09

Hello, Attached is [list-shuffle], which should randomly shuffle the elements of an incoming list. I assume that something like this already exists, but I couldn't find it on a cursory search so I thought I'd send it along on the off-chance that it hasn't been included or that it might help. Of course I'd welcome improvements. Thanks, Matt

Trying to figure out why pix_video isn't working
by jim 07 Nov '09

07 Nov '09

For some reason pix_video isn't working for me. I've tried a few different webcams, all of which work in other programs. I'm on a 64 bit Linux Jaunty machine and using Pd version 0.42.4. GEM: ver: 0.91.3 'tigital' I keep getting this error in the console when I select a camera using a device message VDIOCGCHAN: Invalid argument Any thoughts how to track the problem down and get it working? Thanks, Jim

Hello , is there is a way in puredata to calculate the contours of an image? i would like to get contourns from a web cam in the same way as the findCountor method from opencv library. Is it possible to do something like this in pd? thanks in advance P.

float accuracy and OSC
by alvaro 06 Nov '09

06 Nov '09

Hi I'm trying to send some big float numbers into Puredata through OSC. But numbers seem to be rounded up above 16777216, that's 2 to the 24. Numbers are really rounded, not just printed with less precision. Has it something to do with OSC, or with mrpeach objects, or with Puredata itself? Alvaro

folder_list relative paths
by Stephen Lucas 06 Nov '09

06 Nov '09

We've been having some trouble using the folder_list object from hcs to work with paths relative to the patch folder. We have a folder inside the patch folder and it seems as though you should give folder_list an argument of "./foldername" or "./foldername/*" or "foldername/*" but no combinations seem to work. We're using Mac UNIX and although absolute paths are working fine, there would be some very annoying problems if the patch relied on folders always being in the same place. Has anyone dealt with this problem and discovered a solution, or is there a better object to be outputting the file contents of a folder? Thanks, -Stephen

combining 2 or more cameras to output 1 stream in Linux
by jim 05 Nov '09

05 Nov '09

Hi, Does anyone know the easiest way of combining 2 or more camera outputs into one stream? ie. how can I take two cameras using 320 x 240 and generate a wider image 640x240? Is this possible in PD? I would like the resulting stream to be available in v4l ie /dev/video0 + /dev/video1 = /dev/video2 . Any thoughts on this? Thanks, Jim
