Tell us about yourself!
You could fabricate your own making a sensor bar with 88 LDRs or 11 8-LDR modules each with a micro controller to process the 8 sensors. The scrolls are 9 holes per inch. Use a foot long florescent tupe as the source on one side of the paper and your fabricated "reader" on the other.
Thanks for the great instructable ! Technically to calculate the length from hinge to rod for 1 mm per minute rod rate youwould use 1/((2*Pi)/1436) rather then the tangent formula . The tangent error will then be corrected by the cam constructed.
Ooznest / Ustepper Motion Time Lapse / Video Rail
would like a pdf of the construction.
i was thinking this would be a cookbook on getting wifi going on a PI but i guess not.
"Turning" a Dowel on the Bandsaw
why make when you can buy for same price?
