Thanks to Yale-NUS undergraduate and FabLab aficionado, Daniel Pyone Maung, for building a Hall Effect instrumentation amplifier for the lab following instructions from this old article in Scientific American. We are hoping that the heartbeats of an insect or spider will cause enough movement in an attached magnet to register a signal. This summer, Gena Soh will try to test this device as part of her research internship with us.
