Coulbourn Instruments manufactures good quality electronic shockers and cages that can be purchased cheaply on the used market. The hardware and software for controlling these instruments is outdated and can be discarded. It is relatively simply to build Arduino based controllers that are vastly more flexible and easy to use.

This particular instrument, which was built in our laboratory, controls one shocker and eight cages using an Arduino, custom software and high voltage relays. It allows the user to select from multiple different programs for testing and using the apparatus.
