$10 is an awesome price point. I've never toyed with any of these, but i think i'll pick one up!

How long do you think it'll be before i can safely hook up powered electronics into a system like RasPi? I'd like to make my home "smart", but i don't want to have random IoT vulnerabilities in my home. So a simple network of tiny linux machines powering desk lights/etc will be plenty for me. However, hooking electronics up is dangerous, so i'd rather wait until a professional makes it accessible to someone like me.

Thoughts?
