Just got several of these toy calorimeters, meant to teach 7th graders about specific heat and Joule's law. My plan is replacing the heater coils with 50 Ω coax loads, adding motorized stirrers, instrumentation with PT1000 probes, and running two of them in a differential bridge configuration, actively balanced by opamps for RMS to DC conversion, upgrading them from 7th grade physics to college physics. #electronics
