barn door project, stepper motor without Arduino???
MOTOR;
POWER SOURCE...maybe a battery pack? not sure yet.. i'm out in the field so it needs to be portable. any suggestions appreciated.
DRIVER ;
CONTROLLER.
Once i get this all up and running, i might be tempted to get into more precise control via an Arduino, especially if the the above kit is too clunky. But the level of tracking accuracy at this stage is probably not a issue. My current thoughts on the engineering will be that the bottom block of the door has to have some mass to supress general vibrations plus vibration damping motor mounts, i will be using high quality stainless steel, ball bearing door hinges. Adding an adjustable alt/ az sub-base for finer polar alignment.
Any input from experience would be appreciated and pointers on keeping things metric would be helpful, pretty much all the guidance out there is in imperial units....

Re: barn door project, stepper motor without Arduino???
FWIW let me offer a comparison. I have built a barndoor tracker for a 10"
This design is good for up to 200 mm and does not have a polar scope - I simply eyeball the hinge direction towards whichever side of Polaris the

here it is... it's not the best forum submission in the world as this forum template is woefully out of date and excruciatingly painful to use
