Shutter Controller and Programmable Sequencer
This controller has two functions:
- To properly power and actuate a UniBlitz mechanical shutter
- To implement a programmable timing sequence
The implementation is based on a microcontroller and a DAC (digital-to-analog converter). The DAC sets the threshold for stimulus pulses, and the microcontroller times the sequences that were designed in a graphical user interface.
This sequencer was designed and built for the Michael Johnson group.
