Hi all, I've had a paper tape reader for a while but never had a punch to make new tapes, and the ones i've found are not only very large but also very expensive. So I'm toying with the idea of making an open-source punch, but I can't find any detailed diagrams of how the mechanism works.
I'm assuming (without any data to back it up) that there is a cam, an array of spring-levered pins, and horizontal spacers controlled by solenoids that bridge the gap between the cam and each punch pin when called for. Does anyone have insight into how reliable/fast paper tape punches work? -- Anders Nelson +1 (517) 775-6129 www.erogear.com
