Using ADS1220 with Load Cells in Wheatstone-Bridge

That looks quite tiny!

Unfortunately that doesn’t fit with my current concept due to the circumstance that i needn’t the strain-gauges integrated.

Edit:

One moment - i 'm going wrong here, don’t i? The BWGR pins went out to the bridge?

I’ll take the opportunity to show off whats is in my mind, but beware - everything made on a whim. No calculations - just gut feeling!

The red squares are representing the strain gauges.

On the front side is the accommodation for the noisy ADC board.

This is just an impression how things may look with some more parts assembled but still incomplete.

If anything will work as i expect, i would be quite happy!

Edit:

Here you can have a look at the predecessor without strain gauges. I was trying tap probing with the ADXL with this one, but unfortunately that didn’t work out with my slow and sturdy machine.

I got impacts to slow to recognize, but too powerful not to harm head and bed.

So the head you can see here, has never seen filament.
:sob:

That is, why i like to try load cells now.

Here you can see how the strain gauges are embedded in the printed head-carrier. For protection they will get covered with ‘acetone-ABS-soup’ in the next step.
