This looks like an excellent project. Well done!

Thanks, not sure how far I'm going to take it but designing with selling them in mind.

@@Ed.R What software are you using for that 3D layout?
@Ed.R
@Ed.R 3 года назад
@@mindracing Its a feature in the EasyEDA software which I'm using to design it. Using EasyEDA because its linked to JLCPCB which I've use once before to make my power latch circuits. They did a great job and the software seems good so far to. The 3D model is amazing for checking the design.

@@Ed.R I use KiCad for designing but I've used JLCPCB for board production on my last project and the were really good. I'll give EasyEDA a try. Thank you.

Please can you make a video on schematic and design calculations of this board

I'm sure that I can contribute much more by doing so as most of what I know is just taken from the datasheet and covered in previous videos. I'm no expert with the software if that's what you mean, still new to it myself. The design in this video is already needing improvements.

Hello, I did tryed soldering the two pins of channel B to ground, but then the raw value went up and fixed. Didn't charged no matter how much I was pushed down the scale. I do have a cheap middle sized green board.

That's interesting to know, I had better test before keeping them. I was only going by the data sheet which perhaps isn't the best idea. Thank you for mentioning this. Have been lazy and not done this on my boards in use.

I tried grounding the unused channel on a red board, which has correct grounds, and it didn't affect the output. Didn't improve noise either so don't think it's worth doing.

Hello, can you please share the board design? I have a smaller one with a metal shield but it jumps around and also drifts over time.

There is nothing really special about the design. It just has the issues discussed in previous videos fixed and more ability to customise it. I would make sure the board you have is working as it should be. Also remember strain gauges are just difficult to work with, noise and drift are to be expected.

@@Ed.R yes, I have increased the voltage over 5v but no difference in noise. Also the pin from the left side it is connected to GND. So I don't really know what can I do to get rid of that noise. It should come from the electrical side. I noticed that running if from a battery instead of the usb or switching power supplies helps. Also it seems to drift over time. I also understood that the clock of the arduino might be to fast... Anyway thanks, let me know if you have any updates
