Torque transducer

I’ve been wanting to build a dynamometer for a while to better characterize the performance of the direct drive and geared versions of the moteus controller. I have now started down that path with a torque transducer, which I calibrated with the below fixture:

I got a what ended up being a low quality load cell amplifier to use with it from the same supplier, although discovered it was total garbage and am now using a SparkFun OpenScale board which seems to be working much better. Soon I’ll hopefully have something wired up that actually has a controller or two on it.
