Here’s how to make a test chamber from a re-wired toaster –
Mark Thoren and Jim Williams needed to test the temperature compensation scheme of a circuit they were designing. The lab had several temperature chambers, but they were always in use. In frustration, Jim grabbed a brand new toaster and plopped it down on Mark’s desk, saying, “This will do.” Not quite. The hysteresis of the oven’s thermostat was 10C â€” too crude to measure the circuit. Mark and Jim scrounged about and found an auto-tuning temperature controller, some solid-state relays and a shiny platinum RTD probe. After some minor rewiring they had a test chamber, more than adequate and better than most of the “real” chambers that were never available when needed.
