Without Bound - Perspectives on Mobile Living

A documentary about people living mobile and off-grid. This is fascinating and inspiring! Highly recommended.

Becoming a Digital Nomad: portable solar system design?

I'm looking to put together a small solar power kit to run my phone, a nook, and laptop. The largest portable solar array I found was a 27w model, but now I need to figure out a battery configuration that would charge those gadgets adequately and in a relatively small package. I don't need an inverter, I can charge my laptop from 12v DC and everything else from 5v DC. My phone and e-reader each pull 1A @ 5v, and my laptop power supply (car charger type) pulls 2.1A @ 19v. The battery is rated for 10 hours of life, I'm not sure what that would translate to in watt-hours (charging rate is 40w). What sort of system/products/parts should I look at for this application?

Making ice with Arduino.

Check out a project I'm finishing up: http://ift.tt/1MHqvF4 http://ift.tt/1gL6sqA http://ift.tt/1MHqvVk http://ift.tt/1MHqwJ9 http://ift.tt/1MHqvVm

I'm able to run a regular cheap home depot freezer as an ice box with 2 x 250w mono panels, super capacitors and modified inverter.

During the sunny times it acts like a freezer and during the clouds/rain it runs just enough to keep the ice block from melting.

I'm thinking of adding a battery charging circuit to it as it seems to have enough excess power during the sunny times to run a fan and charge my phone plus more.

I hope to sell this as a completed kit for those who don't want to build it and share everything else open source for those who do.

Lots more to think about as I finish up this project. Let me know what you think! Aloha.

Building codes and rural property?

Is there some general rule of thumb, as to how I could guess what kind of properties are going to allow me to build a strawbale house, etc? I've always wanted to do that anyway, and I can afford some nice land with a crappy shack to live in .. and build an art house. But how do I orient myself as to where I'm likely to find lax building codes that will allow that? In Canada, BC specifically.
