How and why we built a tiny Internet of Things apartment at SparkFun HQ.
My name is Nick Poole and I like to live weird. I've built abodes in pick-up trucks and retreats in warehouses... but this year, for the first time, I built an apartment at work. Except this time, I had a lot of help... and I'm not gonna live in it. That being said, I'm really excited about this particular domicile because it's on track to become the most technologically advanced yet constructed.
In the winter of 2014 our marketing team got together and started chatting about how to showcase some IoT related projects using SparkFun parts. We talked about a series of blog posts or tutorials but eventually we all decided that video was the best way to talk about the Internet of Things so the brainstorming began:
What was the Internet of Things?
"What about like, um, agricultural monitoring? Soil moisture and pH and stuff?"
"That's not bad..."
"A lot of it is where the home automation movement ended up."
Ahh, Domotics! What a splendid idea! From its humble beginnings as an outlandish idea from the 1934 World's Fair, to the first "wired homes" of the 60s and finally the "smart house" of the 80s and 90s, home automation has been a promise of the future just waiting for the technology to back it up. Sure, automated home appliances like dishwashers and tumble dryers were a big step, but they didn't exactly turn us into The Jetsons. No, to reach the true glory days of laziness we would need inexpensive, distributed and ubiquitous computers – and the far-reaching networks to back them up. If that isn't the promise of IoT, I'm not sure what is.
After a bit more discussion we came up with, well, a pretty obvious idea. Let's build a set, build some projects and just keep adding to it. Eventually it will turn into the home of the future. Along the way, we'll talk about the build process and open-source all of our work so it can be replicated. The projects don't have to be too serious, but they should focus on concepts that are applicable in real life. You may never need your toaster to tweet you, but it turns out that if you can make a toaster tweet then you've learned an IoT skill with a lot of applications! As the set becomes more and more loaded with futuristic goodies, it will also turn into a cool stop on the SparkFun tour. Maybe it can even be the set for future video projects...
We were all on board, it was a great idea but now we needed a place to build our set. The designated studio is pretty large, but it's already pulling triple duty with two video backdrops and a photography studio. Sarah, Shawn and I went location scouting around the office and found a few promising patches. Our first instinct was to use the un-leased, unused space in a corner of the building but after talking it over with Ops we decided it was no good. If the space got leased out, we'd have to move the set. However, that conversation led to our Director of Operations offering up some space near his office so we measured it out and decided it was exactly what we were looking for.
The next step was to measure the space that we had and come up with a floor plan. We knew we wanted three walls and a window and we already had one long wall to work with. We also needed to leave enough space for people to walk through as this was still a sort of thruway. I played with a few different shapes to try to make the best use of the space but eventually I landed on this:
And we took these drawings into a meeting with our long-suffering Facilities Manager. After consulting the fire code and asking a few questions about how we were gonna build it he was totally on board. Done deal, now all that's left is the easy part... framing, sheetrock, putty, paint, trim, flooring and furnishing! As you can tell from the drawings above, I had already framed out the two walls that we were going to build so I had some pretty good materials estimates. We took a trip to the shops and loaded up my truck with sheetrock, 2x4s and various other building supplies.
Most of the work had to take place after office hours since we were making a lot of dust and a lot of noise. Sarah, Shawn and I worked from 5 to 9 or 10 p.m. for several nights putting up walls, and it was actually a really fun time. Our very own Nic B even hung out on a few occasions and shot video (parts of which were in the first Fellowship of the Things episode). We ordered food, put on some tunes and got to work:
The set was framed out with 2x4 studs on 16" centers, just like the walls in your house (probably). One of the walls that we were building, the one with the entryway, would be self-supporting because of its shape and weight. The other wall, the window wall, needed to be supported from the back with braces and weighed down with concrete blocks.
The most difficult part of the framing process was installing the doors. I hate hanging doors, so we bought some doors complete in their frames from the local building salvage. Unfortunately, the only matching set we could find were solid. Solid doors are heavy so they were a challenge but we did eventually brace everything adequately. While we were at the salvage yard, we also bought a window and that got installed in the opposing wall.
While framing is certainly the bones of a wall, it isn't what you would recognize as a wall. To turn a frame into a wall, you need to put cladding on it. Sheetrock is relatively light, can be cut with a box cutter and is designed to take paint and primer. It really is a fantastic material. A few drywall screws here and there and the sheetrock was all hung. After that it's just a matter of taping up the gaps, filling the screw holes with putty and sanding it flat!
Even though we wanted the apartment set to be a clearly separate space from the rest of the office, paint was a good opportunity to bring it in and make it a little less alien. We chose to use paint that was left over from the accent walls in the office building. We left the existing wall alone.
To finish up the walls, we bought some (relatively) inexpensive pine molding and baseboard. This was trimmed to size and nailed into the studs above and below the sheetrock. We didn't stain or oil the trim but I may go back and wax it just to keep it from absorbing moisture and getting stained or warped.
With the walls finished, the set looked very close to finished but we couldn't imagine anyone having replaceable, low pile carpet squares in their home. Luckily, the office carpeting is easy to pull up and replace so Sarah and Shawn ripped that up while I was en route with fresh flooring. We decided on a combination of carpeting and (not quite) hardwood.
I snagged a few cases of "fold down" laminate flooring and Sarah joined me in snapping it into place. It went in really quickly and easily, the hardest part was trimming around some of the weird corners. We hid the rough edges under an area rug which finished out the flooring and gave you somewhere soft to put your feet while you relax on the sofa.
Speaking of sofas, we still needed furniture! I love designing interior spaces so I jumped at the chance to furnish the place. Eventually we'd like the apartment to include a kitchenette, an entertainment system... you know, a "house kit." But to get started I went for dorm room furnishings: futon sofa/bed, coffee table, side table, chairs and a desk. All of our furnishings came from Target (imagine me fighting college freshmen for cute throw pillows).
The lighting is all from Target as well. The sconce lighting is actually intended to be wired external to the wall but as I have the advantage of being able to walk behind the wall to wire things, I simply drilled holes to allow the cables through and plugged them into a surge protector on the backside. This allows us to easily insert a PowerSwitch Tail or similar device in the future to control them. The pendant lamp is an inexpensive lamp combined with a fancy Edison bulb and a piece of steel bar stock that I bent in a vise and screwed to the wall with brackets for a handrail.
Of course the interior of the apartment isn't the only thing that got finishing touches. The "front porch" of the set got some brick facade, house numbers (number 000), and even a front porch light which will be integrated into a future project! Of course we needed a door mat and a doorbell as well...
The creative techs worked hard to put this thing together and we're really excited to add projects and watch it develop. We hope you'll continue to follow our progress and if you missed the first episode then you can check it out here!
