Strain gauge multiplexer

I created a  strain gauge multiplexer that is used for sensing the force on five (x,y,z) points on a wear tester.
It contains a multiple strain gauge amplifier and a multiplexer board.

I made a batch of totally 9 board that I have sent to seeedstudio for production.
Mostly the boards are for my PnP project, I was planing on waiting a few more weeks before sending the batch for production.
But i have to create the camera vision SW/HW function in quite a hurry because i took on the vision implementation as a curse project in school. So I desprately needed the light ring for the camera, aka lighthouse.

P&P Update: Vision test app

I already know that I am going to use some sort of a vision based alignment functions to be able to place component based on captured image.

The first approach is to find any solution that enables camera integration and vision based functions, so I can build my own shape detectors and alignment routines.

Tested many different solutions until i found EmguCV which is a C# wrapper to OpenCV which is a very capable vision platform.

So I did a small app to see if i could do a component pad search function.
And this is the result.

Solder Station v2 Board is up and running

So this is one of the milestones in a project, when the board is up and running and seams to be working as expected.

The screen layout is just a “test” to see how it can look like.
