I'm not competent to propose a talk on this, but I wondered if anyone out there wanted to do a hardware talk?
Off the top of my head I can think of a range of ruby-ish things:
- Freerange's Printer that's an arduino talking to a web backend written in ruby
- connecting buttons and games controllers to ruby programs
- using ruby with the raspberry PI's GPIO to make physical stuff happen
- using ruby to drive Lego mindstorms through Bluetooth
- talking to DMX(?) or MIDI controllers for lights, music, etc.
Are there libraries that make this easy? Are there people making ruby-powered robots? Can ruby drive a car? How much electronics do you actually need to know to make things? How little electronic knowledge do you need to avoid electrocuting yourself or your family?
I don't know whether anyone on here has interesting stuff to present or wants to tackle this. I'd bet there's someone lurking though...
I guess my ideal talk would be one that after hearing it, I'm immediately inspired to go online, buy some components, automate the house, build a killer robot, etc.
