Instant Omni Pro 18 Toaster Oven and Air Fryer

Recovered as part of unrelated e-waste pickup of Coffee Brew bits.

This particular device is some version of functional, with some dim display segments and plausibly faulty touch regions. Display/buttons communicate with the main power and relay board using something like serial communications around 1200bps. Reverse engineering the communication protocol to implement an alternative control interface. So far blinky and "singing" CW has been achieved using oscilloscope and logic analyzer dumps and then re-creating the signals using an ESP32-S3 running Micropython.
