Tips and tutorials related to Pro/Engineer, Excel (primarily) and others like Tcl/tk (occasionally)... I had started another topic on Arduino as well. Here I try to explore the underestimated and uncommon options...
As posted last time, I had received the rail. I have it integrated now. Also, i have implemented the camera triggering aspect. I am using opto-isolator for that. I got it all put together. Now I can use it for taking photos as expected. Here are some pictures of the setup.
Although I knew the coupling of the motor with rail knob would be challenging, I didn't think it would be this difficult. I had to plan - make, next plan - make again, several times before I could settle down. The alignment is real key in getting the motor to work without getting stuck.
Install limit switches for the rail,
Add physical switches for power ON/OFF, LCD ON/OFF, Motor ON/OFF.
