The document discusses using TI SensorTags and a BeagleBone Black to create Internet of Things applications without wiring. It describes using the sensors on the SensorTag, including temperature, light, motion and magnetic sensors, to monitor and visualize the status of a toilet remotely. The proposed architecture involves connecting the SensorTag to a BeagleBone Black via Bluetooth and sending the sensor data over a Bluetooth WebSocket connection. Examples of other potential applications mentioned are a security alarm system and elderly monitoring system. The BeagleBone Black is recommended due to its open source hardware, pre-installed operating system and IDE, and ability to run programs without Unix commands.
This document discusses Tokunuino, a software engineer based in Aizu Wakamatsu, Fukushima, Japan. It summarizes his work developing local hardware and technologies at FabKura, a traditional Japanese storehouse used for community workshops and projects. Some of the projects mentioned include creating an Arduino compatible board called Tokunuino, building a 3D printer, and developing sensors that collect and analyze data for potential future applications.
The document discusses the author's initial experiences learning and working with Amazon DynamoDB, a fully managed NoSQL database service. Some key points:
- DynamoDB allows for flexible data structures and extreme performance but is not suitable for complex queries. It uses a NoSQL model with primary and secondary indexes.
- The author created tables for a forum application and implemented a simple REST API for basic CRUD operations on the tables.
- While DynamoDB requires less maintenance than self-managed databases, the author notes it has limitations like the inability to modify indexes and less flexibility for querying data.
- Additional tools like Pentaho ETL were used to process and load sample data into the DynamoDB
