niconiconi on Nostr: RF/microwave calorimetry experiment - Significant progress. Its binding post and ...
RF/microwave calorimetry experiment - Significant progress. Its binding post and heating coil are now replaced by a BNC connector and a 50 Ω SMD resistor. It also has automatic stirring built using an RC toy propeller (lab stirrers are too large). The inner metal cup is now a plastic beaker to reduce its thermal conductance and capacitance. Now I'm waiting for more plastic parts to mount the PT1000 probe. #electronics
