I've been changing around a few minor things so far.
It turns out their portamento function works a hell of a lot better than my mildly kludgey smoothing code (most definitively not a function in its past state). Now the pitches are continuous.
I changed the code to only accept lists of 2 length which fixed the last recurring bug. I ran the fixed version of my code for a long time (roughly 30-45 minutes) without crashing.
The only time it crashes is when I pull the USB cable out which seems reasonable. I'm not sure how to fix this.
I changed the graphing to happen with actual transparency instead of what was happening before. It turns out that transparency hides in the stroke() that is used to change the color of the line or figure drawn.
example:
stroke(gray , transparency);
stroke(r, g, b, transparency);
So far I've had fairly good success at creating them. I've started a text doument documenting each version of the sensors. Each sensor is labeled with sharpie. I've written short descriptions of the construction and problems (and solution if applicable) for each sensor.
My studio in woodard is starting to become more useful. Today I brought a soldering kit and the eyebrow switches.
Here are my notes on the stickytape sensors (so far):
ly accept lists of 2 length which fixed the last recurring bug. I ran the fixed version of my code for a long time (roughly 30-45 minutes) without crashing. The only time it crashes is when I pull the USB cable out which seems reasonable.
version 1 (11/17/11):
construction:
doubled up ~4.5" long pieces of tape with 3 layers of velostat between. 2 ~1.5" pieces of conductive thread are the contacts.
problems? :
No. Conductive string is not long enough and therefore the resistance does not change in a meaningful way. There needs to be more overlap.
version 2 (11/17/11)
construction:
doubled up ~2"x1.25" composite pieces of clear masking tape.
3 layers of velostat.
2 3" pieces of conductive thread.
problems? :
No. Conductive string does not overlap. Pushing on the dead zone between the two thread peices does not change the resistance. Pushing directly over the thread traces does.
solution? :
Use overlapping pieces of thread.
version 3 (11/17/11)
construction:
doubled up ~1.25"x1.25" composit pieces of clear masking tape.
3 layers of velostat 1"x1"
2 3" pieces of conductive thread (placed on a single strip first)
problems:
I'm finding the conductive thread contacts to be sort of lacking.
solution:
In future versions I will follow Plusea's advice and use conductive cloth as the contacts. (really small pieces!)
version 4 (11/17/11)
construction:
doubled up diagonally situated composite pieces of clear masking tape
3 layers of velostat
2 3" pieces of conductive thread
2 small pieces of conductive fabric
problems:
does not work. too much contact given by conductive fabric. No range at all. Diagonal placement of tape is wasteful of tape.
solution:
do not place conductive fabric over the same area as the velostat. this will prevent excessive contact.
