Fast PASTA: converting an HX711 module to 80 SPS

This video guide for hacking a readily-available HX711 load cell module for 80 SPS output, thus making your PASTA faster! For instructions on HOW TO MAKE PASTA, see:

PASTA is an open-source platform for neuroscientific research based on a hacked kitchen scale. It has been used for prepulse inhibition sensorimotor gating analysis in our original PASTA paper [1], as well as quantification of grip strength (griPASTA) [2].

Bon appétit!

Almost pulled the whole chip off to cut traces underneath it watching that other guys advice. This is way more newbie friendly. Thank you!

I'm trying to build a quick shifter for a bike. This will help a lot. Big Thanks!

Thanks man. I have a ton of this basic boards and needed an easy way to modify.

thanks, man!!!! did it easy, used a needle and a soldering, really fast and easy, working very well now!

Hey Davor, thanks for the video h you seem like a HX711 expert, so i hope you could help me. I tried with a slightly different board. The Jopto CJMCU-711, which is also sold under some other names. It has two pads marked rate at the lower side. It does not seem to make a difference whether I bridge those or not. Output is still 10hz. The pin 15 is also always low. Would you have any idea what I did wrong?

Hello there, great video, I have a hx711 board that I brought, looked just like yours in the video on the amazon advert, but what I got it's slightly different where the little components are, have heard it may need resistor removing or moving to make it 80sps ? Do you think this might be true

Thanks alot

hello man. thanks for the explanation. if i need more than 80 sps, can i increase it maybe around 500-1000 sps ?

I am getting lag in input to a computer... It appears, on pressing button it notes 0.3s late. By running on 80SPS will this solve the issue? OR long wire (1 mtr + USB cable) causing the lag?!
I made a DIY handbrake for racing games using loadcell, Hx711, Arduino Leonardo Atmega32u4.

Will this fix input lag using Arduino as a game controller on PC? I have this board with a 20kg load cell and when using it on the PC it takes a second to register as well as releasing, and I need it to register immediately for a brake for sim racing

What a vandalism to brutally cutting the pin of the chip!
Just heat it with a soldering iron and lift it up with sharp blade.
