The speaker shares personal IoT projects like an interactive wedding cake and a solar-powered hydroponics system to illustrate real-world applications.
A buzzwire game was developed for an AWS re:Invent booth to create an interactive experience demonstrating distributed tracing with a live leaderboard.
The physical game was prototyped using Tinkercad and printed on a dual-head 3D printer with OctoPi, using repurposed TV coax cables for the wire.
The project uses an ESP32 microcontroller with an initial cloud architecture plan involving AWS IoT, SQS, Lambda for processing, and DynamoDB for storage.
The older ESP32 board failed to connect to AWS IoT due to an outdated SSL certificate, a problem that produced no clear error messages.
To bypass the SSL issue, the architecture was changed to have the device send data directly to a public AWS Lambda endpoint via an HTTP GET request.
A live demo shows how distributed tracing can identify that a data type mismatch error originates from DynamoDB, not the Lambda function processing the request.
Key lessons from the project include the importance of planning for extra time, monitoring everything, and the unexpected usefulness of keeping old cables.
The speaker answers audience questions about AWS certifications, recommended languages, databases, security considerations, and future trends in serverless IoT.
