clem! Posted March 11, 2009 Report Share Posted March 11, 2009 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.

rosch Posted March 11, 2009 Report Share Posted March 11, 2009 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: http://www.electronicpeasant.com/ Quote Link to comment Share on other sites More sharing options...

stryd_one Posted March 12, 2009 Report Share Posted March 12, 2009 Hahah that was my first thought and I didn't post it... my stupid memory :) 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.

clem!

rosch Posted March 19, 2009 Report Share Posted March 19, 2009 Resistance per 10 cm 37 Klooks 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...

clem! Posted March 20, 2009 Author Report Share Posted March 20, 2009 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 ;) mmh.So let´s test everything we can find and put the information together.clem!

bosone Posted March 20, 2009 Report Share Posted March 20, 2009 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...

clem! Posted April 22, 2009 Author Report Share Posted April 22, 2009 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:http://www.spulen.com/shop/product_info.php?products_id=543Who has sampled experience with resistor-wire-controlers.Best regardsclem!

clem! Posted April 22, 2009 Author Report Share Posted April 22, 2009 Mmh there´s s.t. better I think:Isa Chrom 60http://www.isabellenhuette.de/pdf/WIDER_LEG/DE/ISA-CHROM.pdfat D=0,011 mm seems to be ideal for an 85 cm Wire-Controler another one is Isaohmhttp://www.isabellenhuette.de/pdf/WIDER_LEG/ISAOHM-ISABELLENHUETTE-R.pdfat D=0,01 but where can I buy it as an end-user ???

stryd_one Posted April 22, 2009 Report Share Posted April 22, 2009 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 :) Quote Link to comment Share on other sites More sharing options...
SLP Posted April 23, 2009 Report Share Posted April 23, 2009 but where can I buy it as an end-user ???Conrad. Home > Components & Kits > Passive Components > Resistors > Other Resistors > Resistor wires There's only one wire called "isachrome"10 m isachrom 60 resistance wire (5.65 ?/m) Quote Link to comment Share on other sites More sharing options...
clem! Posted April 23, 2009 Author Report Share Posted April 23, 2009 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)Regards Quote Link to comment Share on other sites More sharing options...

stryd_one Posted April 24, 2009 Report Share Posted April 24, 2009 we need a diameter of 0,01 mmThat's *very* thin... are you sure? Quote Link to comment Share on other sites More sharing options...
clem! Posted April 24, 2009 Author Report Share Posted April 24, 2009 Toaster wire?Good idea! ... there must be ... somewhere ... a broken toasterThat's *very* thin... are you sure?of course it´s thin, but if we fix it on a plastic strip it must work - I hope so - if not we need a wire with a bigger diameter made of other material.clem!

TheAncientOne Posted April 28, 2009 Report Share Posted April 28, 2009 This company in the UK sell a large range of resistance wires, though they are not that cheap.I've bought from them in the past to make foam cutters.http://www.wires.co.uk/acatalog/nc_bare.htmlThey are a subsidiary of this company http://www.scientificwire.com/ Quote Link to comment Share on other sites More sharing options...
