I really appreciate your in-depth response, I'm learning a lot from just attempting this project. I got in touch with loadstar and they do have the serial TTL output, which I'm going to go ahead and jump on since that seems to be the best option. The things are so damn expensive, I really hope the project works. Trying to figure out what makes it so expensive. The scales are nearly a grand and their precision is .1-.2 grams. I didn't even see an option for .05grams so I'm curious what exactly they're charging so much for. Will take a look at what other companies offer the serial TTL option because that truly does seem like the right option. Thanks a lot, I'll update with pictures and more information or questions when I can.
