a small plate of 1 mm copper sheet
2 19/22 silicone septa
1 24 V DC power source - Anything between 12 V and 24 V may work but the results achieved here use 24 V. Motor speeds may need calibration to match existing results
1 Arduino UNO R3 - or equivalent microcontroller that can output two independent 5V PWM signals and connect to PC over USB serial
4 cm² of conductive felt
160 cm² of gasket sheet - Dimensions must be at least enough to cut out approx. four 6 cm x 8 cm rectangles, an A4 sheet is enough
100 cm² of grafoil
1 L298N motor driver
4 M6 nuts with washers
4 M6 x 35 mm hex socket cap bolts with washers
several male-to-male breadboard jumper cables
4 cm² of nonconductive felt
2 peristaltic pumps
some polypropylene filament - This can be substituted if you only plan to run water through the cell for testing things other than the chemistry
several cm polypropylene packing tape
A4 sheet separator sheet
some stiff filament - PLA works
44 cm of tubing
1 USB A-to-B cable

1 10 mm socket - To fit torque wrench
1 5 mL syringe
1 50 mL beaker
2 50 mL beakers - or drip tray/other container to hold 10 mL of water
1 5mm hex key
1 FDM printer
1 gasket cutter machine - Vinyl/laser cutter or hand tools
1 pair of chemical safety goggles
1 pair of nitrile gloves
1 PC - Must be able to flash firmware to microcontroller and connect over USB serial to microcontroller and potentiostat
1 potentiostat - preferably the MYSTAT
1 scale
1 stir bar
1 stir plate
1 torque wrench - to accept 5 mm allen key or 10 mm hex socket
1 utility knife
1 vial - min. 20 mL
1 weighing spatula
