First Release To Do List

[zerox1212]

Software

• Finalize load cell class, store some data in the LC class, make more generic for future use with other drivers
• Add calibrate methods to find reference unit automatically
• Add way to store load cell configurations on disk and restore automatically
• Finish scale control calculations
• Implement and test Bluetooth communication from RPi3
• Implement and test basic Android app to receive Bluetooth data

Electrical

• Update PCB design to allow jumper selection of Channel A or Channel B on HX711 (in case gain of 32 is needed)

Mechanical

• Finalize load cell mounting plate design
• Create basic BOM

where can I get one of these pub boards... im looking to do this and have lots of questions. would you be able to help??

You want one of the PCBs? I might have a few left, but no one is actively working on this project. In fact I would highly recommend any efforts on a scale solution use the pyrometer project as a base and make a wireless platform.

I havent checked out the pyrometer project. Have you had success with this project or is it still a work in progress. I just want to corner balance my car lol. I’m having to start at the beginning, 1 scale wired up, moving to two scales and so on. Paul Brann

Paul,

Check out my post on reddit. https://www.reddit.com/r/arduino/comments/g32aqw/i_made_a_set_of_race_car_scales_for_my_sons/

If you need any other info, email me at mastasloth@hotmail.com

I'm using arduino at the moment, I'm Looking into hooking it up to Pi in near future and possibly going wireless.

This project has enough code to read a load cell and also a very basic UI. However to get it to run you will need to be a programmer and I never actually ran the UI on Pi (you will need to know Linux to get it to work probably).

Would be much smarter to take the pyrometer project, swap out the thermocouple board for a loadcell board and you have a much better and more valuable project.
