Jumpei Matsumoto from the University of Toyama has generously shared the following about Tetroplater, an open-source circuit for microwire tetrode gold plating.

“Gold plating is necessary/effective for microwire tetrodes for recording neuronal activity. For the gold plating, the electrode tip is electroplated with current pulses, until the impedance reaches to the target value. The Tetroplater is an open-source low-cost (<200 dollars) circuit including an impedance meter and a current generator for tetrode gold plating.”
