Experimental controllers sensors ribbons et cetera

Hi all!

What about starting little experiments with alternate controllers and sensors.

Maybe at first we can sample the resistance of different video tapes (I´ve found some old panasonic ones), we can also measure adhesive metal tapes or other materials like different graphit-finishs and put the´samples together into a database.

Don´t know if this is the right place to do that - any suggestions.

Hope there´s s.o. else.

i’ve tested some antistatic nylon bag in which ICs are packed for use as a ribbon controller. i haven’t completed this project until now because my main circuits didn’t work (psu?).

it has the required resistance of 100 kohms when cut to a band of about 20cm / 1cm. these were recommended for a diy belt controller project, the builder did it with adhesive tape and graphite powder and a brass strip, i intended to use this nylon with a violin string.

the website i found the original circuit with the adhesive tape has some very interesting projects with vacuum tubes:

Sure is!

What an interesting site, I love the “slinky” reverb :slight_smile:

EDIT: Not sure about beads from a beaded seat cover used as knobs for potentiometers though…

Hahah that was my first thought and I didn’t post it… my stupid memory :slight_smile: ACSensorizer is midibox stuff and you can find goodies on our wiki/forums too…

AudioCommander has done great work with this, it’s a must-see for alternative controls.

First samples of video-tapes:

Manufacturer;      Format;        Type;             Resistance per 10 cm;

Panasonic;           MII;              AU-M60L;       11 M;

Panasonic;           S-VHS;          XD;               4,3 M;

Sony;                 Betacam SP;   BCT-30MA      4,6 M;

Panasonic;           S-VHS;          SE-30;          7,8 M;

Kodak;                VHS;            HS-E240;        2,3 M;

TDK;                   VHS;             E-240TV;       -;

TDK;                   VHS;             EHG;             -;

Akai;                   VHS;             HQ;              -; 

Agfa;                  VHS;             S-HGX;          -;          

Hi all,

found another one - this is as somewhere else told a scotch consumer one.

Manufacturer;      Format;        Type;             Resistance per 10 cm;

Scotch;              VHS;            EXG+;             37 K;

looks much better!

clem!

Resistance per 10 cm          37 K

looks much better!

hi clem!

which resistor value/length are you looking for, what would be the best?

do you prefer video tape (bec. availability)?

perhaps i could measure some old multitrack and stereo recording tape too.

but i actually think those tapes would easily wear down after short use because you’d always have to press a metallic surface on a very thin layered film…

hi rosch,

first project is to build a controller with the full length of a keybord with 61 standard keys for my keyboardcontroller-midification-project. That means 10 k at ~86 cm.

But “I have a dream” for the next project - of building a continuus-polyphonic-velocity-sensitive-(midi)-controller (schoene Wortkreation) for small money like the continuum at haken audio which costs megas.

Maybe we can find s.t. like graphite-cotton :wink: mmh.

So let´s test everything we can find and put the information together.

clem!

i replaced today my home made ribbon sensor with a spectra symbol softpot (30 cm long).

it is much more reliable and precise.

for a ribbon controller, i’d suggest the soft pot solution + the AC sensorizer…

If you want all the way analogue, take a look at this: http://www.electro-music.com/forum/topic-28138.html

mmmm spectrabeatnils

hi there,

interesting video. Are there some infos about the making of this controlribbon.

I have googled a little bit about “konstantan” and found this:

Who has sampled experience with resistor-wire-controlers.

Best regards

clem!

Mmh there´s s.t. better I think:

Isa Chrom 60

http://www.isabellenhuette.de/pdf/WIDER_LEG/DE/ISA-CHROM.pdf

at D=0,011 mm seems to be ideal for an 85 cm  Wire-Controler

another one is Isaohm

http://www.isabellenhuette.de/pdf/WIDER_LEG/ISAOHM-ISABELLENHUETTE-R.pdf

at D=0,01

but where can I buy it as an end-user ???

Who has sampled experience with resistor-wire-controlers.

I’ve seen them used in basic flight control systems… It works like you’d think, just a wire with high resistance.

As for sourcing it… I’ll let you do the hunt, good luck :slight_smile:

There’s only one wire called “isachrome”

10 m isachrom 60 resistance wire (5.65 ?/m)

hi and thx for the quick respond,

Yes I´ve seen that, but it has a to low resistance.

For our aim, building wire-controlers, we need a diameter of 0,01 mm with a resistance of 11580 Ohm. I think with this wire we can also build shorter controlers of 30 or 15 cm - hope they won´t get to hot  8)

Toaster wire?

Fuse wire?

we need a diameter of 0,01 mm

That’s *very* thin… are you sure?
