Oddly fascinated by the leaves
We’ve been watching an excellent crowdfunded documentary series called Woodlanders. It brought to our attention a guy working to reintroduce the chestnut tree to American forests. We couldn’t believe it was even possible to acquire young chestnuts so we pretty much had to place an order. It arrived this week and to our surprise it still had leaves from the season previous. This is when it hit us what it meant to be planting this.
Solar monitoring back online
The solar instrumentation has been lacking for a couple of months since the solar panels’ current sensor blew up. It took 2 months because there has been a lot mistakes and learning along the way. It should have been simple, replace the 30A sensor by a 100A one right?
Well it wasn’t. First I ordered the wrong 100A sensor, meant for AC use. Then I had a myriad of issues around calibration.
- at the 5V input port, a 0V reading didn’t translate to 0A, this sensor goes from -100A to 100A so it is 2.5V which translate to 0A.
- with the skew from miscalibration, the value I was getting made no sense for what I know the panels can make
- orientation matters as again, this sensor can read negative values
- a cloudy day makes fluctuations hard to detect
- moving the sensor from one interface kit to another after calibration resulted in another skew.
All these little things I could have picked on their own, but together they conspired to make me thoroughly confused and left me seeking support from the Phidgets forums. I was once more impressed by Phidgets, the help I got was fast and efficient. Phidgets are more expensive but I was proven once more that they are worth every penny. They have many other advantages, I have nothing but good things to say about them.
Calibration, I really need to tidy things up in there
I’ve learned a LOT of lessons with this one. Not the least of which is to be ok with the imperfections of analog data. I’m a discrete data type of guy, it doesn’t come naturally to accept skews & variations.
Just in time fire
We’ve had no wood reserves for 2½ months, what little left we had was consumed by the unexpected or trying to make starting fires quicker. It’s ok though we’ll be warm, fuel literally grows on trees. All it takes to harvest is a bit of exercise, a beautiful day doesn’t hurt.
Ash trees have a special place in our hearts given how many times they saved our bacon. It’s a shame they are getting ravaged by the emerald ash bore, what will the future ill-prepared homesteader do when their wood reserves don’t meet the tribute demanded by Winter?
Working my way up to the canopy
I was taught to not waste a branch, I moved the canopy elsewhere for later processing, for now I need the quick yield of the trunk
A fair amount for the time spent.
More solar lessons
I always wondered why the solar array never produced more than 30A, especially after I added 3 more panels to it. Well, I got my answer yesterday when the array took an unexpected dive.

I had forgotten that the amperage sensors I got back in 2015 are only rated for 30 Amps, way overkill at the time :). So it’s entirely possible the array was producing more and I simply wasn’t able to “see” it. Also, the extra panels pushed the sensor over the edge and fried it.

I put in the order for new sensors rated for 100A, it will be interesting to see what the graphs look like. Their design also makes it so if they fail, the production won’t be impacted because they aren’t part of the circuit.
It’s surprisingly difficult to find such sensors rated for high amperage. Phidgets are expensive but they pretty much have the only industrial IOT sensors. In my experience they are robust and easy to deploy thanks to great documentation & code samples.
Unforgiving
We’ve been dealing with a brutal cold stretch which is most definitely testing our limits. The timing isn’t great, after a Summer of construction and an addition to the family in October, our wood reserves aren’t exactly plentyful.
A few days ago, I came to the realization that at the pace we are burning wood, we only had 10 days of reserves left.
I thus decided we would not use this pile any more, keeping it available for the unexpected; we will instead produce wood as we burn it. I had 2 ash trees picked out since the Summer, they didn’t look too good, and they’re close to the house, they’d be perfect to finish the Winter. I didn’t realize they’d only help us start it. And so I went after them in the best temperatures this cold stretch had to offer, which were still quite low and made for some very tough work. I also grabbed a couple of dead poples while I was out there but they don’t burn as good as ash when green.
The morning routine now consists of splitting 2 sleds worth of wood, which covers 24 about hours.
We folded back into the tiny house to make heating easier, it’s not too chaotic but we do miss the extra room.
The green house is incredible and turns a little bit of sunlight into non-freezing temperatures.
Building it around the well’s pitcher pump was an incredibly smart move.
The snow and the wind also take jabs at us, really it’s been one thing after another. Equipment is reaching its limit. I suspected that the tractor’s battery would be dead at some point, and so I thought I’d jump it with the ATV. What I wasn’t counting on was that the wind would push the snow back on the paths I had plowed, making it very difficult to get close to the tractor to do so. I had the unexpected planned for, not the doubly unexpected.
The cars also make funny noises and smells with such temperatures, anything mechanical is taking a beating. So is my body which does not get a single day without unforgiving chores outside.
The solar array batteries barely function as they are frozen, we’ll want them in a milder environment later on.
The porcupine is undeterred by the cold and still sets out every night for its routine. It picked a different tree this season and seems to like some of the paths I made.
A friend gave us an aloe plant a while back, and I never paid much attention to it. Today though, we opened it up and rubbed some of the magical goo on our hands. It felt amazing and it’s nice to feel something other than biting cold, logs and hot stoves every once in a while.
We reached the lowest temperature since we moved to the land on January 2nd.
So here we are, one tough stretch reaching extremes and pushing all our limits. It’s ok though, I enjoy getting tested by the elements, this is what drives me outside during a storm. Still, we’ll be very relieved in a few days when we get to catch our breaths. We’ve learned a few good lessons along the way.

Feels very good to chainsaw, it had been a while and I had been itching.
They went right where I wanted them.
And for your viewing pleasure here’s just the tree going down, notice the little pine way out in the back getting utterly whipped.

x1.5
Another Winter another solar upgrade. Short overcast days are good at exposing a lower limit. After having lost power a couple of days it was time for an upgrade. The house is growing and so it our consumption, especially on the Summer months when we get used to abundant electricity.
Bringing the panels on site, I always said my son would make a great draft horse.
I’m becoming good at building in the cold, my fingers are not thanking me though.

All I need to do now is prop it off the ground and anchor it for heavy winds. 
I like this frame, it takes 6 2x4x8 and this is the only scrap lumber left.
I did some quick back of the envelope math and so far our setup costed about as much as what we would have paid for grid electricity these past 2 and a half years. Seems like it costs about as much to learn how to fish than it does to buy fish, at least at the beginning. We have now entered the gravy zone.
