Manual/Description to follow. Please contact me if you are interested in building one yourself right away. We may also be able to send a limited number of pre-built shakers around, if time and funding allow. Download the STLs here.

We frequently use the MyoPacer and various chambers for it in our experiments. Over the years, we've repaired and modified them. One addition is a 3D-printed tightly-fitting top of a PH-1 chamber (Warner Instruments, Hamden, MA, USA) designed to minimize evaporation—especially important for small volumes and longer experiments (>10 minutes) for experiments that don't need direct access to the chamber and don't use perfusion. Simply print the chamber and place a coverslip, sealed with silicone grease, on top. Download the STL here.

Additionally, we've replaced the electrodes of these chambers multiple times. We’ve had good results with platinum (8€/cm; example supplier) and platinum–iridium (3.5€/cm; example supplier) electrodes, both with a 0.5 mm diameter. You’ll need 5 cm of wire per electrode, which should be carefully bent to match the original form. I also recommend crimping the connectors onto the electrodes and securing the connection with a shrink tube. Gold-plated D-SUB connectors are both affordable (0.3€/piece; example supplier) and reliable.

Simple Arduino-controlled, stepper motor-driven screwdriver, primarily for the automated control of passive force in MyoDish chambers. Bitholder is attached using a flexible shaft, so it can also be used while the chamber is on a rocking table, without needing to physically 'rock' the motor. Also works in high humidity/temperature environments (e.g., incubators). Comes with a simple GUI for the Arduino, which allows for protocol-based adjustments. Can also output digital signals for synchronization with other devices, such as the Digidata amplifiers (Molecular Devices, San Jose, CA, USA). Synchronisation is particularly useful for the automated control of the motor during electrophysiological recordings, such as sharp electrode recordings.
