Kirby Gordon ’20 has built an elegant four-channel controller which we will soon use to drive mechanical shutters constructed from laptop hard drives (following Rev. Sci. Instrum. 75, 3077 (2004) and Rev. Sci. Instrum. 78, 026101 (2007)). TTL pulses sent to the controller cause the shutters to toggle from open to closed. Thanks also to Jason Mativi (the Williams College electromechanical technician) for helping to sort out the hard drives!
