The overly high tech methods used in the project amuse me: design it with a CAD system, use a laser cutter to cut the wood, design your own gears, write C program for microcontroller to driver stepper motor- (advantage: easily adjust for astrophotography from other planets). It's too much meta-work.
So here is my new challenge: make it using only parts and tools available from Home Depot.
(even so, I have to get one of these laser cutters..)
- lutorm 12y agoI made one a long time ago: two planks, a hinge, two nuts, a threaded rod, and a camera mount. Operation was by turning the threaded rod 1/4 turn every time my HP48SX beeped. :) It's actually advantageous to be manual when you're doing this at -25C on a cold winter night in Sweden. Batteries tend to not work well at all at those temperatures. (And no, you don't need a curved threaded rod, you can just calculate what the correct rate is as a function of position.)
