This project is more than just a load cell test set, it measures the thrust of a static motor test and provides numerous details and insight into the functionality of the design.
The microcontroller monitors the current thrust, detects motor ignition and starts logging the data until the burn is complete.
After the static test, information such as burn time, sample statistics, average thrust, total impulse, peak thrust and a motor designation is given immediately without having to be placed into a spread sheet for further post processing.
The individual samples are displayed where they can be copied into Excel to produce thrust graphs with amazing simplicity.
There is now a wireless ignition channel!
