Computer vision is exciting, but it usually takes a sterile approach to images by identifying the objects in the photo. This project sought to use computers to assess fine art on some qualitative metrics. The programs were adapted from existing models and compared to human judgments, so unlike a human, results are repeatable and not subject to a person's current mood.
Wiring on the controller took a day and a modular breadboard. The breadboard should be moved off before long since it looks awful and stays stationary because of a rubber band. All the crimped connectors took time and crimping to thin wires is a recipe in frustration.
For testing, the controller's face rested in a project container. All the inputs were programmed so they would trigger the onboard LED. The program was written so that each input had a couple of registers associated with it. When an input was pressed, it would trigger a one-shot bit, and another bit would stay high until the button was released.
A short PVC cylinder with bearings was assembled. Bearings were held in place at the center by using reducers. For the main barrel, I used 4" PVC, which is heavy and much stronger than necessary for this project but easy to find. A length of 5/16" (8mm) threaded rod passed through the bearings. It was light enough to hold still for a picture, but the full-size version will be a few times longer. That one will probably require a solid rod, not a threaded rod.
The heavy cylinder for this project called for a sturdy base, and a flimsy camera tripod was not going to cut it. Even a rugged work light mount had too much play. I spent a day creating a platform that would be rigid and easy to build. I designed everything around 2x4 lumber.
Then I built it.
It was strong enough to hold me and not wobble. I used adjustable feet for leveling and a slot in the top where a 5/16" (8mm) rod could mount and lift out for convenient transport.
The rest of the summary posts have been arranged by date.
