Re: [PD] OT: Ir leds
You probably want the brightest ones (usually measured in in mcd) you can get! Besides that, if you know anything about the camera you are using that would help a lot, for example which part of the spectrum in nanometers it is most sensitive to. Then you can match it to the spectrum emitted by the LEDs. Another characteristic is the angle of the LED, in your case you probably want them to be pretty wide. Some LEDs are low current or ultrabright, which mean they are better at making light from current. Ultrabrights, however use a ton of current at their brightest. This is usually only a concern if you are running from a battery or very weak power supply (or in something like a voltage controlled synthesizer when a sudden big current draw can have audible consequences!). So once you understand the characteristics of the LEDs, you can choose the ones for your budget. You'll still have to do a lot of testing to get the right amount of light for the space and your camera. It's always of a question of whether you have more money than time, or time than money. Somehow I seem to have neither these days, I wonder what I'm doing wrong! ;-) Best, Derek On 8/30/10 4:44 AM, ronni montoya wrote: Hello everybody, i dont know if here is the correct place to ask, if anybody know another forum related to this , i will be very happy if somebody can show me: Im making an interactive floor and i need to iluminate a space of 4 x 4 meters with ir light.

Re: [PD] live pd patch mixed with Gem or pdp?
ok I got the modules to load by reloading the kernel image sudo apt-get install --reinstall linux-image-`uname -r` sudo depmod -a now Yves solution works with pdp_v4l. although modprobe v4l2loopback seems to work, Iohannes's incantation to launch the pipeline returns: WARNING: erroneous pipeline: no element v4l2loopback also /dev/video3 becomes available when I modprobe v4l2loopback but nothing can seem to access it --- invalid argument errors. Assuming I can configure webcamstudio to autostart with the configuration I need tho, I should be all set at this point.

This is a 2-headed machine (one machine --- I'll use 2 if I absolutely have to) and the plan is to show a Gem or pdp window fullscreen on one head and a pdp window fullscreen on the other. This leaves me not sure where to put the Pd patch for the screenshots.
