there are some radical changes to our proj again. hopefully mit soon, so that we can discuss.

cathode solution possibly change to potassium ferrycyanide K3Fe(CN)6

in the broth side, we'll add 1ml 50micromolar methylene blue. methylene blue acts as electron carrier for the oxidation, it helps carry the electrons to our anode so the transfer is many times more efficient, leading to better readings of voltage. hehe.
