Hi,
I came upon some devices which could be interesting to use as controllers
with pd. I don't know if something like that already exists, but wanted to
ask if it seems possible to modify/create a protocoll that would allow a
connection between those devices and PD itself. AS I am no programmer, I
really don't know if it is possible or not.
The devices are in http://www.techdesign.be/projects/023/023.htm and
http://www.techdesign.be/projects/008/008.htm . As said, probably there's
already something much more fine, but there seem to be simple and portable
enough to be quite handy for an improvisation.
Greetings,
Joao

The devices seem to support the USB-HID protocol, so they should work with Hans' [hid] external.

Hi,
The page says this thing has both USB (HID) and RS232 so you should be able to use [comport] or [hid] (but the later may be more sticky)
Maybe christian is working on some multiIO module for something like this?

there are complete compass sensors available, either digital (only giving bits for the 4 directions), or analogue (with continous output), like these here:
http://www.imagesco.com/catalog/DigitalCompass/DigitalCompass.html
they _could_ be connected to the multio (or any other sensor interface that uses the 0..+5volt indistry standard for that purpose), but since the voltage swing is below one volt, a small op-amp circuit may be needed.
range-finders are also available, either as ready-ti-use units or as kits, that also have a 0..5 volt output. if you dont need the high-range of serveral meters, i recommend the use of optical sensors, like the ones from sharp (at the lower right, the ones with the analogue output):
http://dkc3.digikey.com/PDF/T053/1586.pdf
also, im starting to create a miniature-version of the multio that will fit on half a euro board, so only 100x80 mm, maybe 20 mm height, with the same functionality as the big box with one userboard. since that involves the use of only smt devices, it is much more complicated to build yourself. that will be done after i got the new firmware up....
anyhow, if someone needs something really small and simple, heres a hint: use the microchip 18f4550 microcontroller. that one has a built-in usb interface. there are tons of ultra-simple circuits to program that chip. that chip also has a/d converters integrated, so you can directly connect sensors to it. all the needed tools are freely available on the microchip site. even more, if you get the chip itself as free samples, you can make yourself a small interface for below 10 dollars, using usb.....

chris

According to some feedback I got back when trying to advertise the Multio, it's more important to make the device cheap and simple-to-build than to make it small in size. However, it should be possible to make the device a lot smaller than it is now just by cutting on the features (as in: making those features optional, as daughterboards)

the problem is the available space. as you can see, its pretty full. only way would be to cripple down the possibility to extend it, and thats not what i want to do.
however, it would be no problem to design a smaller, easy to build unit that is just not extendable, but would use the same firmware.... but my main intention was a modular system that is usable for large installations and setups as well (like a virtual mixer desk, which requires a lot of fader and buttons)

chris

Well, to make more space, can't you make more features _optional_? that's exactly what i'm suggesting above.
Make the AC/DC conv external and optional. Make the MIDI ports optional.
BTW if you also turn the IDE-like connectors on their side then you can save on the thickness because the AC/DC's capacitors and MIDI plugs are the tallest components on the board. If you keep them vertical but put inverse connectors on the back on the daughterboards then you don't need cables anymore (and I love the LEGO-block concept of it).

Olá João,
I believe you can find alternatives to those here:
http://infusionsystems.com/catalog/index.php
Although expensive, I am not totally sure of this but I believe the great advantage of I-CubeX is that their sensor's signal can be easily converted to MIDI which makes them very easy to use in any kind of software, including PD.
Adeus, Nuno

midi boxes have serveral drawbacks .... first, default cc messages have only 7 bit, so you have a range of 0..127 only, unless you use a few other cc's (like pitch), or refer to rpn's/nrpn's.
second, midi in hardware is rather slow if you play around with sensor data from many sensors and/or high resolution. plus, it requires you to have a midi interface in your computer.
otoh, usb is fast, available on almost any computer/handheld by now and due to standards like hid, easy to use as well. oh, not to mention that there are midi definitions for usb, so a usb device can register as midi device to a host, making it accessible by the hosts midi system.
if you only want to do 1 or two sensors, midi (not usb or usb-midi) is nice. but for more, it becomes pretty limited quite soon. the problem is that sensors usually dont have a "stable" output like a fader. it varies much more over time, generating a constant flood of messages. i prefer to have sensors as much "realtime" as possible.....
and yes, 600 dollars for the system you mentioned is way too expensive. that just a rip-off, imho.

chris
