You can see the copper creeping around the coil, it is the white colored stuff over the black.
This setup takes about 20 minutes to completely plate a muscle, whereas it took days before.
The electrolyte is copper sulfate and h2so4 with a copper pipe that the muscles are wrapped around to stretch them out allowing plating between coils. The copper pipe goes to the negative terminal.
The positive terminal is just some copper foil.
The 8-track player box was repurposed to house my 3d printed stir plate contraption thingy.
A stir bar was made using a piece of ptfe tubing a neodymium magnet and some silicone.
The voltage reads zero for some reason but current set to 100 mA and voltage set to .9 volts before hooking it up works the best.
