For my group design project one of the main tasks was to determine the amount Lego blocks stacked together. The group gave me this task, so I decided to make a weight sensor based on strain gauge. Hopefully I'll be able to briefly explain how it is done and what obstacles I had to overcome.
Warning: the article turned out to be rather large
Hopefully, it will help someone out there in the world to get over frustation faster, when working with strain gauges.
Thanks hackaday for publishing my article!
