USB interface for various 9 axis movement sensors with data acquisition software.
Miniature Bluetooth 9 axis movement sensor, inbound IR synchronization emitter, outbound radio synchronization receiver and battery charger, data acquisition software (see the paper describing the project and the applications here: http://www.nature.com/articles/srep35689).
Subminiature electrophysiology preamplifier.
Electrode Interface Boards for neuroscience research.
These are only example projects presented here for illustration purposes. I also have developed animal position video tracking software and many other more or less complex experimental setups or devices.
