For some time now I have been setting up a quality control system, which has started with a basic weighing system, which connects to a database and sends the information, and will end, I hope, with a counting system based on image recognition.

I've been doing a lot of testing, and finally I've acquired an old precision laboratory scale, from which I'll use the casing and load cell. The scale comes of course with its button panel and LCD screen. It is an absolute pity not to be able to reuse them in the project, and to avoid having to use an external system to control the scale.

I have looked for information and questions, also here, and I have an idea that recovering these components, without a deep electronic knowledge (I am an agronomist), is going to be complex. I think in my favor I have that the LCD comes with its controller.

Anyway, I thought it would be interesting to show you the model, and see if you can guide me on how to recover these components.

  • \$\begingroup\$ What you need to do is get a (clear and in-focus!) closeup of the IC labelled U1. This should allow recovering a part number, and then Google is your friend (maybe). At a guess, the trace from the top (blue) wire in the flat cable on the left is a serial stream which is somehow fed to U1. \$\endgroup\$ – WhatRoughBeast Jun 1 at 18:18
