The parts are all here! Sam and I (mostly Sam) hooked up the 10x zoom lens we ordered to a Chinese-import cs-mount variant of the raspberry pi camera module, while improvising some arduino-based lens motor/feedback controls.
The lens, bottom, zoomed in on Arthur Whitney’s infamous one-page J interpreter on my wall, controlled by breadboarded arduino, and projected from the Pi in perfect focus onto some foam core by the window.
