"Build Your Own IoT! Fun With Python and Raspberry Pi."
summary
Builds a working live pipeline: a 1.5 V mini solar panel (~$20) wired through an ADC into a Raspberry Pi (≈$133) reading a voltage every second with nine lines of Python using Adafruit libraries, packs readings as bytes/JSON, and pushes them to Apache Kafka on Confluent Cloud via the confluent-kafka Python client. Demonstrates one producer and one consumer, shows Kafka Connect syncing to Elastic and Snowflake, mentions Pico alternative ($6), and confirms the end-to-end flow runs in real time.
