This list will connect the community of panels system users. The project was developed by Michael Reiser as a graduate student at Caltech. The system is composed of embedded microcontrollers used in an LED-based display and a multi-microcontroller based control module. The system consists of hardware developed on two systems, and 4 different pieces of software (written in C and MATLAB). All code and circuit schematics are freely available online. The system has proven very succesful as a stimulation system for use in presenting controlled visual stimuli to insects in laboratory experiments. Currently there are about 7 other groups that have this system in place or are developing it now.
