This repository holds the resources for a flexible, spatial visual stimulator with up to 6 chromatic channels. It combines commercial digital light processing (DLP) devices with open hard- and software components that can be easily adapted to the experimentalist’s specific needs. With this we intend to start a community effort of sharing and further developing a common stimulator design.
Please find more details on the stimulator in the following publication:
