The Desk of Ladyada - Sample Sunday & a NAU7802 tester start
This week we did a lot of sample testing! First up is this cool conductive rubber sheet. We sell conductive rubber cord, but we had a recommendation to get some 2D shapes as well. This material is easy to cut and has some changing resistance with movement. We also got a motorized potentiometer sample, which is super fun - we're using a simple H-bridge to send the 10K slider back and forth. Finally we're working on our NAU7802 tester, since our order of NAU7802 chips finally came in. This is a load cell amp chip that has I2C interfacing, but really it's for any precision wheatstone-bridge-like…
