Description: 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 things. The Great Search - 24-bit PGA + Differential ADC (NAU7802 Replacement) digikey.com/short/qwm3rn4z We are working on getting our NAU7802 Stemma QT breakout into the shop - this is a 24-bit ADC with differential input support, and programmable gain for quick interfacing to strain gauges and other wheatstone-bridge like sensors. Great news is we got a shipment for our order from Digi-Key, but they're out of stock again with a long lead time. Let's find an alternative ADC for folks who want to measure similar small-signal sensors!
