I'm not sure if this is the same thing, but I'd like to see a product family that can be configured to replace controller boards on a wide family of appliances. For instance, a generic compressor/thermostat controller that will work as a replacement on ALL models of refrigerator for the past 20 years. It would work based on jumper settings or loops that you add/cut that would be qualified and tested for each model. It's working with power levels that could burn your house down, so safety would need to be paramount. But basically all appliances do the same thing, just at different voltage and current levels. There should be a market for a common replacement set.
