Oh, that's sad.
I really do not like that "powder" idea and printing conductive ink
is too expensive....
I thought i have found someone who will try the epson for me....
seems i must do this myself.
> conductive ink from Precisa, which is $52 for 0.1 Kg (smallest order).
1kg = 1l water, isn't that fun?
i expect the ink to be maybe 2 to 4 times as heavy as water, so
you maybe get 30ml. definitely more than 10ml.
