The document provides an overview of prototyping and bringing Internet of Things (IoT) devices to market from Jeff Katz of KIWI. It discusses prototyping sensors, best practices like building multiple prototypes and using hot glue, and connectivity options like Bluetooth Low Energy, WiFi, and LPWAN. It also outlines the process of taking a prototype to a product, including firmware development, testing, manufacturing documentation, safety certification, and organizing production.
Building Connected Hardware (for the internet of things)
- 1. Jeff Katz | KIWI Building connected Hardware (for the Internet of Things)
- 2. A bit about me • Background in engineering and business • Ten years experience software • Seven years building connected hardware » Me, in 2002, at a national robotics competition
- 3. What we’re going to talk about • Internet of Things! • Prototyping – Tools, best practices, connectivity • Connectivity – different technologies and their use cases • From Prototype to Product
- 5. Prototyping - Purpose • Trying to determine if the user experience will be good, or if the design elements are okay? – Non-functional Design Prototype • Trying to determine if it will work? – Functional (Read: ugly) Prototype • Don’t try both!
- 6. Prototyping – Sensors • Machine Vision • Ambient Light • Acceleration • Tilt • Magnetic • Liquid Level / Leak • Force / Load / Pressure etc. • Flow • Presence / Proximity • Velocity • Temperature • Moisture • Chemical / Gas • Sound / Vibration • Location
- 7. Prototyping – Best Practices • Prototype is going to cost at least 100x what the final product will cost (and 10x as much as the first manufactured devices) • You’re going to have to re-engineer it completely • Never build less than two • Hot glue is awesome
- 9. Connectivity Summary slow fast nearfar cheap expensive less power more power BTLE WIFI LPWAN Cellular
- 10. Side note: Privacy & Security • Don’t collect data you don’t need • Don’t transmit data you don’t need • Secure all communications • Allow remote updates A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away. — ANTOINE DE SAINT EXUPÉRY
- 11. From Prototype to Product Time Money (Prototype)
- 12. From Prototype to Product • Firmware development – (up through full functionality, or minimal functionality + firmware over the air) • Develop full testing plan • Create manufacturing documentation • Gather safety-relevant documentation for certification • Determine required safety regulations for markets • Pre-qualify safety and electronics • Finalize hardware design
- 13. Where to manufacture? • More than 100.000 per year? – China • Super specialized processes? – Probably China, or whomever does it already • 100-50.000 per year? – Locally!
- 14. From Prototype to Product • Release hardware for manufacturing • Certify hardware is in compliance • Gather WEEE registration • Design packaging, manuals, etc (also in compliance with regulations) • Organize manufacturing, assembly logistics • Ship devices
