Conversation about paper tape reading methods #3

Open felipesanches opened 3 years ago

Hi, @tingox! After you opened issue #1, I got curious to learn more about the methods you're using to read paper tapes. And also which projects are you interested in / working on that use paper tapes.

I've got access to some interesting tapes, but could not yet really figure out an efficient way of reading them all. I would be happy to learn more about your efforts.

For projects, I have two drawers of old paper tapes to read, that is all. The contents are most likely programs for NORD-10 machines.

The method: I have started building a scanner using a Raspberry Pi, a Pi camera , a stepper motor driver and a stepper motor. The plan is to move the tape, take a picture, have OpenCV decode it, and repeat until done.

If this will be a reliable and efficient way to read tapes remains to be seen. :-)

nice! Be sure to let us know! And feel free to contribute code to this repo perhaps.
