Hello all.
I've been interested in Arduino and the whole electronics community for a while, but never can get anywhere. I have a friend who does canvas painting, and needs his paint to stay active by being constantly turned.
I have a couple ideas in mind of how to go about this project, but I need some pointers, as in what kind of motor I would need, etc.
Sorry if this is in the wrong forum category or if project is too basic
That is not a very helpful project description.
Basically I need to create a base that can hold a few dozen paint bottles, this base needs to rotate constantly. The total weight of the bottles is about 35lbs, what kind of motor would I use?
You will need a disk, supported by a ball bearing race (look for "Lazy Susan" in a home improvement store), that is wide and sturdy enough to hold the bottles.
The disk could be connected by a belt to a gearmotor shaft. Select a gear ratio so that the disk rotates at the desired RPM.
I would also use the Lazy Susan fixture for the turning part and the wooden disk mounted on the fixture. But I would add a rubber wheel to the motor and press it against the edge of the disk to make the disk turn.
You might spend a few words on just how turning bottles around on a disk will keep the paint active. It will certainly not be stirring the paint.
I had the same thought. The mixers I have seen are more shakers than rotaters.
Only change I'd make here is to use an A/C motor instead of DC to simplify wiring. Nothing to do with arduino, but that's OK.
If the disk was tilted up at an angle, you could get some swirl motion.
My ‘Can Shaker’ uses an Arduino
Nano and a powerful solenoid to, er, shake a can. Of anything, but spray paint was my objective. At a settable frequency and a settable duration (max 5 mins).
With a much larger holder I imagine it could be adapted to several cans. Their weight is obviously a major factor, not one I think you’ve mentioned.
And, of course, a regular motor could be an alternative to my ancient surplus solenoid, whose last incarnation was as a shoe stretcher a few decades ago.
