Hi All,
I imagine that this question has been asked a million times in various ways, so first up, my sincere apologies.
I have quite a bit of programming experience, and a reasonable amount of Linux experience (compiling kernels etc) but the furthest I have gone beyond that (towards hardware) is the Raspberry PI.
My goal is to create a device that can connect to wifi, can run off a battery (a short amount of time only, say 8 hours), can power a few lights (LED's might even be OK. I'd like them to be visible in moderate darkness,they don't need to be excessively bright) and play a small amount of sound (a small low powered speaker for example).
It needs to be programmable, but only needs to be able to parse data coming in via wifi, and to power the light(s) and play a tone on the speaker. It does not need to run an operating system, or perform any operations beyond that, so the CPU requirements are low.
I have two questions: how would one go about started on this, and what sort of cost would be involved in creating one? It is just a little project, so my order would be in the 10's, (so small volume).
Thank you for any help.
