Squishy Circuits - Making Conductive Dough
Materials:
237 mL Water
355 mL Flour
59 mL Salt
44 mL Cream of Tartar*
15 mL Vegetable Oil
Food Coloring (optional)
Here they sell cream of tartar in 8+8g packets, which are about 2 tablespoon (30ml) total, so these are proper metric measurements for 2/3 of dough.
* 160 ml water
* 90 g + 45 g flour
* 12 g salt
* 16 g cream of tartar
* 10 ml vegetable oil
* food coloring to "taste"

Not yet, I've prepared it for an hackspace meeting this saturday.
I've tried sticking the tester leads into it and I'm not really confident it will work; I'm suspecting a translation issue from Cream of Tartar to what I've found in the italian supermarket.
Ahh let us know if it works. Software freedom baked-in at the circuit level, that's where we've got to get to :)

It was a failure :(
It probably didn't conduct well enough, and after one week it was already moldy, so we couldn't even try it (it was supposed to be used with a Makey Makey -like device, so the highish resistance may have been tolerable).
Maybe MOAR salt? That should help with both conductivity and mold...
