tinyblok: monoblok's patchbay on an ESP32-C6: a £5 microcontroller
tinyblok is the obvious next experiment after monoblok: can the patchbay run on a microcontroller and ship sensor data straight into a remote NATS cluster? In the original post, the Peter’s Porsche Rentals worked example put a Raspberry Pi behind the glovebox; an ESP32 is an order of magnitude cheaper and smaller. Coupled with a 4G mi-fi or the car’s onboard Wi-Fi, it’s a self-contained edge node that can sit on a OBD2 dongle’s worth of power and select what crosses the mobile data connection....
