Re: [PD] Usb lights
by robertgarvin＠bellsouth.net 28 Oct '05

What about this... I just remembered that i have a joystick that connects to the computer via a 15-pin plug. to accomodate more modern computers, it came with a usb-to-female 15-pin connector... would that be the same as having a 15 pin port on the compy, allowing me to use "little LED lights?" I assume there would have to be some sort of driver or something, or a pd [object]. I have no knowledge of creating drivers, or circuits, but would be willing to learn. -Robert -----Original Message----- From: B.

(or pay someone to do so) If little LED lights are what you need then such a circuit should not be too hard, but if you have only USB ports on the machine then controlling LEDs would not be too easy, without something like the multiIO, being more expensive than those USB lights. Now if you can find a USB light that someone designed to be controllable, and the company is nice enough to tell you how to control it without enrolling in a developer program then you may have a chance. b. robertgarvin(a)bellsouth.net wrote: > I was thinking about these type of lights: > http://www.thinkgeek.com/computing/accessories/5a84/ > just ones you plug into the compy, and they get the power to turn on. why i'm using usb? because I'm on a dell laptop, and the only ports are usb, s video, a second monitor, and then some weird lookin port... > > robert > > > > > -----Original Message----- > From: B.

I was thinking about these type of lights: http://www.thinkgeek.com/computing/accessories/5a84/ just ones you plug into the compy, and they get the power to turn on. why i'm using usb? because I'm on a dell laptop, and the only ports are usb, s video, a second monitor, and then some weird lookin port... robert -----Original Message----- From: B.

Hi, and thank you for your answers, you have been great.. I don'e know if this is the correct list to ask this question, but.. if I want to run PD on linux, and I have a mac osx, is linux compatible/installable on the mac and what would be the implications of that (could it coexist with osx, etc?

functional generator for DIY-ing
by Andrew Gaydenko 28 Oct '05

28 Oct '05

Hi! If you are looking at an absolute pd-zero, I'm here :-) The aim is to make a functional generator for DIY-ing purposes: sine, pulse with different fillings, switches for freq/level ranges, sliders for freqs/levels, mixing, white/pink noise, and all this under JACK routing. If I understand well, pd is the best to do the thing. Will anybody direct me to learning steps (examples, tutorials, ...) to achieve the purpose in a shortest way? Thanks in advance! Andrew

NameError: name 'pyext' is not defined
by Koray Tahiroglu 27 Oct '05

27 Oct '05

Hello Thomas, hello everybody, I just compiled py library for Pd, and the examples, which are located inside the package seem like they work fine when I ran the related pd file with related pyext obj exp [pyext simple ex1]. When I modify the py file, and run the script inside python, it gives me the following error. File "simple.py", line 73, in '?' class ex 1(pyext._class): NameError: name 'pyext' is not defined is it so that the python, in my system, does not understand pyext, or am I doing something wrong ( or not doing anything) for pd to see the changes in py file? How will I be able to make it right so that pyext objects will just run perfectly well:-) I am using g3 mac os X Tiger, Macpython-2.4 thanks, Koray. ----------------- M.Koray Tahiroglu Media Lab, University of Art and Design Helsinki, TaiK Hameentie 135C 00560 Helsinki Finland http://mlab.uiah.fi/~korayt/ http://purenoise.uiah.fi:8000/ tel: +358 40 754 8449 fax: +358 9 75630 555
