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.\n\nPlease find more details on the stimulator in the following publication:\n\n_Franke K*, Maia Chagas A*, Zhao Z, Zimmermann MJY, Bartel P, Qiu Y, Szatko K, Baden T, Euler T# (2019).
