Building a strain gauge module for learning purposes

Check out PCBWay's website for rapid prototyping of printed circuit boards, CNC and 3D printing services and many more! www.pcbway.com/setinvite.aspx...
In this video, I show you a little device that I built so I can explain more things related to strain gauges, Wheatstone bridges and differential amplifiers.
I reverse-engineered an already existing circuit from AliExpress and made a new PCB based on the circuit which allows a more detailed study of the circuit and its components.

Very good explanations and initiative on your part. Good work!!!👋 I purchased 2 of these modules and intend to use them in a midi guitar that I am building with a Bela board and Trill touch sensors. Because the output is analog, it will be much more simple to implement as compared to a HX711 that requires libraries etc. Thank!

Thanks! I am glad to hear that my circuit can help you!

Le se tagadhatnád, hogy magyar vagy ilyen akcentussal. Amúgy jók a videók👍

Interesting work , I will order this month your PCB from PCBWAY , I have try to contact you in the same to design a daughter board for 1/4 and half bridge but you have provide yet no answer , I need the drill file to match my board to your board . I will send you back my files as I do as spare time .
Could be possible also to to design a filter board with a simple 2nd order filter circuit .

Hi! I sent you the drill files just a few minutes ago. Check your inbox.
