DIY Ribbon Controller Sensor

Michael's icon

Hi

I've been searching for past couple of hours for the hardware to make a ribbon controller a'la this:

...if I could only find a supplier of the ribbon!! (it needs to be flexible -- I've found several suppliers of pc-board style linear capacitive sensors).

Does anyone have any idea where I can get this part?

MAny thanks, and happy holidays!

are you looking for a flex sensor?

Never tried it. Perhaps it's what you are looking for:

Thanks -- No, I have a bunch of these (actually, not had much luck with them because they tend to go south pretty quickly, and will soon only report extreme flexes; bummer because they're $10 apiece).

I'm looking for something like an old ribbon controller on, say, a Moog (or a Trinity/Triton, for that matter).

The tape idea I've read up on, and it doesn't sound hearty enough for my application.

I *know* there have to be parts out there, because if eobody and iCubeX use them, they're there to purchase.

Thanks for the quick replies -- hopefully more will come in??

Best
Mike

That's what I'm looking for -- unfortunately at 60 euros, the one from the Icube is cheaper!! Wow, maybe I should just get that.

Thanks for the lead. I'll try to get hold of that company (it's in germany, right?)

-and yes, *.de means Deutchland or Germany.

I have some quite cool ribbon parts for an old project at my studio, but cannot remember the manufacturer name right now. I'll check soon.

True -- didn't realize the icube one is shorter. I wonder how much the difference in shipping would be -- or if there's an american distributor for their parts (I know there are distributors for their prebuilt stuff).

Anyway, now I have a few ideas. Thanks everyone who wrote in.

Whilst we're on the subject, I've been thinking of having a go at this one,
for some time, but but my circuit bending chops aren't quite up to filling
in the blanks:
http://www.paia.com/ProdArticles/dual-ribbon-howto.htm

Sadly, the author died before finishing the project, and Paia say they have
no plans to make a kit available, so if there's anyone out there who could
put some values on the schematic, I'm dumb enough to need to know what
/type/ of transistors, IC's etc., but should be OK from there,
Cheers

Thanks; this is an FSR, but it doesn't track linear movement on its surface I don't believe. Correct me if I'm wrong!!

If you go back and look at the Paia article, you don't need the circuit board. That adds extra features, but the core ribbon sensor only requires a strip of conductive plastic, a guitar string, and a power supply.

The circuit adds other features such as getting 2 voltages from a single ribbon, plus a gate and sample & hold. But the sensor itself is very simple and can still be used without the circuit.

It was the two voltage thing that interested me...

Check out:

i think this might b what your looking for. I sent in a request for some samples, but never got them? Im gonna just buy a few soon grab an arduino board or the make board and see what happens...
Good luck!

The Arduino board is very cool -- I've been working with it for about a year now and have made some cool stuff. Before that I also had Eric Singer's MidiTron and Dan Overholt's CUI. Of the three, I like the CUI (and the bluetooth version of the CUI) for a couple of reasons: USB (Miditron is via MIDI obviously) and price. A Fully-functional version of the CUI is about $50 -- only a bit more expensive and the Arduino board -- and the firmware is already baked in so you don't have to learn Processing to get stuff up and running. Processing is easy (it's similar to just about every other programming language. But there's something about plug-and-play when you're already dealing with so many other factors in sensor-land.

The Arduino is great, however, if you want to get something working with Flash -- I made a great remote control for use with some flash experiments last year.

A couple years ago I got samples of some conductive plastic material from conductiveplastics.com (fantastic, intelligent people, btw). Hacked together a quick-n-dirty control-voltage ribbon controller in a few minutes with heavy cardboard and a guitar string. I don't remember all the details, but I think the response wasn't quite linear, though I vaguely remember feeling that it wouldn't be hard to remedy that. (Sorry to be vague, but it's been awhile.)

Linear pots (aka faders) always bothered me for music - you have to move something clunky around, and you can't jump around like on a ribbon. Motorized faders are pretty cool (though quite a different approach). Last time I used 'em, they were quite expensive, so I went to Armen's in manhattan and ripped all the faders out of a broken yamaha promix-01. Only 60mm, but cheap ($20 for ~18?) Oh - also - relatively challenging to program.

PS I also love the arduino - it provides the same "oh my god, is that *really* working already" joy and ecstasy that you get from max/msp, processing, python, etc. In fact, I was talking to some non-music non-techy friends about theremins the other day, and ended up hacking one together in about 15 minutes with an arduino and a photocell. And I hadn't touched an arduino in ~1.5 years!

cool, that's our site : )
it works very well btw, i have one at home...
