[packetandy] had an issue. He was nonetheless into basic analog pictures, however native choices for improvement have been few and much between. After some frustration, he determined to tackle the method himself, creating an computerized improvement tank for that very goal.

For black and white movie, creating is pretty easy, if uninteresting and time consuming. The movie requires fixed agitation throughout improvement, which may be uninteresting to do by hand. To get round this, [packetandy] determined to construct a improvement tank rig that might deal with agitation duties for him by wiggling the movie round in his absence.

The tank itself is created by Patterson, and has a stick on prime for agitating the movie inside. The rig works by attaching a NEMA stepper motor to this keep on with jerk it round appropriately. Quite than go together with a microcontroller and customized code, [packetandy] as a substitute simply grabbed a programmable off-the-shelf stepper controller that may deal with a wide range of modes. It’s not subtle, however neither is the job at hand, and it does simply nice.

It’s a nifty construct that ought to see [packetandy]’s black-and-white pictures on the up and up. In the meantime, if easy improvement isn’t sufficient for you, think about diving into the world of darkroom robotic automation in case you’re so inclined!
