Process Goals• Preserve progress between prototypes – Application code – I/O libraries – Look and feel

• Make user tests as authentic as possible • Small jumps between prototype generations – Cost – Time

• Saving time allows you to focus on

• Industrial design

• Companion app

• User testing

• Community building

• Crowdfunding campaign management

• Investor relations

• Building a brand

Don’t Re-engineer: Expand Priorities

The “Right” Tools Are Arcane

@Kinoma

“Just Make it Work” vs “Make it Useable”

@Kinoma

☑ Web (Desktop)

☑ Mobile (Apps and Web)

☑ Server

☐ Embedded

JavaScript’s One Frontier Left to Conquer

@Kinoma

We are preaching the religion of JavaScript for embedded and Internet of Things development.

• Performance

• Memory

• User scripting

• Familiar syntax

• JavaScript coders build cool stuff fast

JavaScript is Ready for the Challenge

@Kinoma

Popular Frameworks Aren’t IoT Ready• Browser-based solutions: Too heavy for IoT devices

• Node.js: Server solution being shoehorned into the embedded space

• Qt: Designed for desktop, too much of a catch-all of features

• Lua: Less popular than assembly and COBOL, so difficult to find talent and no significant ecosystem

@Kinoma

Assembling your Raspberry Pi enclosure is relatively straightforward if you’ve ever built any t-slot based laser cut stuff before, but here’s a full guide…
