Python for less than $7
summary
MicroPython 3.4 runs on tiny controllers and the talk shows setup, firmware build steps and where it fails. Claims: interpreters boot in 75–260 kilobytes and can run in as little as 8k RAM; an ESP8266 with 64k RAM provides Wi‑Fi for under $2.95 modules but needs a separate FTDI, custom firmware and GCC toolchain. Demos include REPL experiments, libraries baked into firmware, bricked and recovered NodeMCUs, and clear limits on standard library and floating‑point support.
