Solar Shed Summary: My Off Grid Office

A few months ago I moved to a few acres in the country, and needed somewhere to work - so I built myself a solar powered off grid office out of a Tuff-Shed Pro Studio!

On one side, I've built a great desk corner with plenty of power and more than enough AC to keep me cool when it's over 100F out.

On the other side, I've built an awesome lab bench for small electronics projects and battery builds.

It all started with this.

That's an 8'x12' Tuff Shed Premier Pro Studio.  I spent around three and a half weeks turning it into my very own office.

Highlights include:
  • Aggressive insulation for year round use: 3.5" of rock wool (5.5" in the ceiling), plus 2" of foamboard on all walls and the ceiling.
  • Plywood interior walls, because I think they look good and they make it easy to mount things.
  • 2kW of solar panels on swinging mounts for power.
  • 12kWh of Trojan T105RE batteries in a 48v bank for storage.
  • A 2kW Aims Power inverter for 110v power.
  • A through-wall heat pump for cooling and heating.
  • Desk space, wall mounted monitors, a lab bench, and plenty of shelving.
This is a summary of my build, with links after each section to posts that contain radically more information (and way, way more photos) of each build stage.

Solar Shed: Part 10: Interior Work

Construction posts about my off grid Solar Shed are nearly done - there's just a bit of interior work remaining before the bulk of the work is finished!

The insulation is done (rock wool in the walls and ceiling, 2" foamboard on top).

The plywood walls are installed.

The HVAC is heating, venting, and air conditioning nicely.

The solar system is rudely interrupting photons before they hit the ground and turning them into electrons.

It's time to finish out the interior, and make myself a useful workspace!  Perhaps something like this:

What went into the interior work?  Read on to find out!

Pokémon Go, Ingress, Servers, and Social Interaction

Pokémon Go has been in public release for slightly over a week now.  I had an opportunity to spend some time playing it in a rather dense area (literally dozens of players around a cluster of PokéStops every evening), and since I've been an Ingress player for over three years, have played plenty of Ingress, and have some background with large scale server systems, I decided to share some of my thoughts.

If you were really, really looking forward to some details on the inside of my Solar Shed (an off grid office I built out of a Tuff-Shed), here's a teaser.  But that's pushed back to next week.  Sorry.

Otherwise, read on for thoughts about scaling, servers, social aspects, and how everything relates to Ingress.

Solar Shed: Part 9: The Solar System

I've collected a bunch of hydrogen and initiated fusion for power!  Or, at least, something that sounds an awful lot like that.  What does one call one's solar system except a solar system, and imply that one has a small sun and planet set floating around?

In any case, you've stuck with me for 8 weeks of "installing insulation and stuff in a shed."  Time for the good stuff!

A solar powered off grid office clearly needs a solar power system - and mine is no exception!

So, here are the gory details on my solar setup.  From panels to outlet.

Keep reading for gobs of details.

Solar Shed: Part 8: Installing the HVAC

This is the eighth post about my solar shed, and I can say that the shed has been working very nicely for me!

After installing a bunch of plywood for your walls, one should, of course, immediately go about cutting a large hole in it!

If you have no idea why I've covered walls in plywood, or why I'm installing an air conditioner, you should start here.  This is my off grid, solar powered office!

Quick quiz: How long does it take to cut a hole in a wall and cram an air conditioner in it, when given a selection of power tools and saws?

Answer: A whole lot longer than I expected!  Walls don't give up as easily as I thought they would.

But I did succeed!

How?  And why this particular unit?  Read on!
