Hi,
I'm involved into a controller (diy) design and I need some help.

My idea is use stribe for neck and keys (or wathever you want) for trigger notes and touch on/off to cutting audio (but maintain pitch bend adjust)

I need "visual feedback" from the position of pitchbend (last point touched) and wondering about phisical neck I think in put the left bargraphs perpendicular to right (with softpot in the middle)

I was wondering about the possibility of double sized (or two stribe linked) for better physical resolution.

One solution could be 2 stribes face to face (one of them reversed) and some coding for make them dependent.
The second solution will be the same but with one input instead two (and controlling the two stribes as one double sized bargraph display)

Sorry about triple posting but I need some help and the forums seems a bit sleepy... I love Stribe since the first time I saw it at internet and I'm very glad to get all my resources for growing concept and community.

Thanks,
Mudo

I have thought about a longer stribe, and have done some initial work to create a "stribed" cello neck.  There is a 500mm touchstrip available, which you can purchase at curiousinventor.com.

As for illuminated feedback, I see how your idea of 2 stribes end-to-end could work.  Like you said you would have to flip one of them to get them to tile together as a continuous strip of LEDs. 

It might be easier, though, to make a custom PCB for this application, or not use a PCB at all.

For instance, you could use a wood neck, drill holes, and put a sstandard LED in each hole, then wire them up from the back side and use some MAX7221 chips to light them up.  No PCB really necessary if you're willing to do a lot of soldering.  Also not necessary to have a double-strip of LEDs like the stribe has.

This is a very interesting project - please keep us posted!

I'd agree with Josh, that a custom pcb or a few proto boards with lots of soldering would be the best route.  Right now, there are three leds in the last block of 10 that aren't connected (just because the led bar graphs come in 10 led units, and we have 64 lights). 

Actually, you could hack saw off the end of the PCB, and put the bar graphs starting in the last active spot.  Then two stribe1s could be mounted flush to each other.  This would save a LOT of soldering time, but would require some code tweaking and some creative mounting.

We've got a lot of dud pcbs if you want to try hacking on a practice one or two... or 10.

I was wondering on it too...

The idea of two led lines is because I want to implement the neck rotation for add tremolo effect (cool eh?) and still give feedback in the 0 degree position and 45 degrees position.

I'm learning arduino at medialab (here in barcelona) and my electronics knowledge is growning (from near 0) and any help will be apreciate.

Soon I will post a draw about my concept and we could work on it altogether (my idea is make it opensource resouce project but it is a "special demanded" from a barcelona's artist)



It could be possible with stribe 500mm softpot get better "resolution"?

I will need some coding help...

xD

COOL! maybe I could to try with 4 of these?

Thanks again you are mellow people!

Until my wait of curious inventor package I'm wondering some ideas...

If I want to "remake" the led config with regular leds instead "bargraphs", how should I wire the 64 leds?

Any link?

Ouyeeeeeeeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaah!

BIG THANKS JOSH!

Take a look

I have all the part for my project except led and max chips (and some pcb protos)

Tomorrow day for buy!

Hi,

I have a shield stribe 1 kit compatible with these features:

1 stribe input.
3 analog inputs.

midi out and analog output (cv?) for the stribe sensor (switchable from midi).

A little help please?



...

[curiousinventor]

Hey Mudo, can you be a little more specific with what you need help on?

[Mudo]

I have the shields solded at least (many work, few free time).

I'm just wondering how to focus but the needs for my project are:

3 analog inputs plus stribe one.
2 or more digital inputs for control octaves and another features (I'm wondering)

Midi out (din) standalone for attach to any synth or keyboard.

That's it!
