Journal 2021-01-17: Phew, some sun...

January always seems darker and more winter than December. I'm scraping my batteries for a few dregs this week, and clearing out a bunch of apps, keeping reading to a minimum, etc. Panels are full out today though.

And just for fun, here's a shot of the old guinea pig bedding composting the veg patch, and the fallen broccoli waiting to sprout. Does anyone know anything about purple sprouting broccoli?

Journal 2020-11-29: Experiments, Behaviour, and Modularised Safety Net Frameworks

For 6 months of 2020 I was wondering where the rain was. The clay earth in the garden dried out, and ants scurried between merrily along the pathways of cracks that opened up. The duckpond dropped until early walls and old statue plinths resurfaced.

Now we lurch into winter, and I'm wondering when the clouds will disperse again. In a traditionally British way, there's been precious little sun, and when it does come out of hiding, it carves its low fast curve across the sky, skimming the chimney tops.

So I'm stretched - I've hit a half-battery of power left a couple of times. But, necessity is the mother of invention. And I figure the goal of all of this is not really to run off solar power as such, but to learn as much as I can about the process as possible. There's a risk in life that you get comfortable and reach a local maxima if you're not careful - that you stick with what is working. But that can risk ignoring opportunities to experiment, to learn new ways of thinking and doing - and in turn, that risks getting blindsided when all the factors making you comfortable shift and slide.

To frame experimentation and encourage yourself to try different things, it often helps to have an "acceptable safety net" or set of fallbacks. In my case, I'm trying to balance learning with a sort of 'solarpunk value set'. On one hand, I want to learn about how batteries and power efficiency work a little. On the other hand, I want to run off sustainable energy as much as I can. But experimentation means upsetting the balance between the two a little to find alternative approaches.

In theory, I could have experimented earlier, when I had more power around. But gluts make us lazy, or allow other experiments (think of all those "odd" recipes you try when you know you have a spare batch of ingredients in case things go wrong...?) So I think it's fine to get back to basics when the nights start drawing in.

My experimentation is falling into two parts - modifying existing behaviour, and finding alternatives to what I'm doing.

1. Modifying existing behaviour - Reconfiguring devices to be more efficient, and reconsidering my use. On top of clearing out apps, I've switched to trying out Accubattery as an Android battery monitor. I've also switched from using DNS66 to Netguard as my 'blocker' Android VPN-style service. I'm seeing adverts again, but locking down apps more - I'll see how that goes.

I'm even letting the battery run out a lot more - yesterday, I got "caught out" after taking some photos in town, and the battery ran out without having a spare on me. I traipsed around with the family, but it was something of a relief in the end, not having to worry about missing phone calls, messages, or photos. It made me realise how much the "convenience" of being always-on means you stop thinking ahead, and just rely on a quick message in times of "mild peril". And it made me want a decent camera I can carry around more easily than my SLR.

With reduced usage and a few app switches, battery life is doing pretty well, as the following line shows:

I'm intrigued as to how well this compares with others - maybe I'll start a survey of how often people charge up their phone, or something.

Also, it means I'm reading more papery books and magazines again, which is good - my reading backlog is not a thing to be trifled with.

2. Finding alternatives. The fundamental lack of sunshine is a bit of a killjoy, on the other hand. No matter how much I optimise usage and behaviour, if there's no sun then there's no sun. Then what?

I can map out my "safety net" - the systems that I fall back to - pretty simply at the moment:

  • solar power
  • mains power

That is, if my batteries run out, then I can plug into the wall. We're signed up with Pure Planet, a proper renewable-green-backed energy supplier, which helps. But is a whole world away from that whole 'solarpunk' disconnected idea.

How could I extend out that safety net map to factor in more diversity of local energy supplies? What other levels and fallbacks could go in there?

After reading William Kamkwamba's book, The Boy Who Harnessed The Wind, I think about the simplicity of dynamos a lot more. I live in a windy part of the world, but do I have the skills to build a windmill? Even then, dynamos actually require a fair bit of power and/or time to generate a sizeable amount of energy - would I have planning permission, robust architectural skills, or the time to cycle around for a few hours a day? Some kits are available though, perhaps it's worth experimenting.

(Side note: Could courier services double up as dynamo'd energy suppliers in a local setting? eg Could a team of local delivery cyclists also drop off and collect recharged/discharged power packs to the local community on their rounds?)

Or what about installing waterwheels in drainpipes and waste water pipes? We don't have much constant rain and don't bathe all day, so I'm not sure how much it would generate. Still, perhaps there is a small-scale opportunity to use water as a battery - use electricity to pump water higher up when the sun is out, then release the water into a waterwheel-dynamo system when the clouds are persistent. Water-as-battery is so simple (in theory). And this isn't a million miles away from all those solar-powered fountains down the garden centre... Hmmmmm.

Anyway, I haven't decided anything here yet, but am finding it useful to have a hierarchy to work with, as each step of that can be planned out in its own, decoupled way. I like this idea of modularising our supply chains more consciously and openly. It feels like a useful way to share knowledge and skills too.

Thoughts welcome - I feel like I'm at the start of a good direction here, but I'm not sure if it's one path or many, at the moment. There's a tiny bit of sun this weekend though - I'm still managing to resist giving up. 20 months and counting!

Journal 2020-11-14: One Battery unpicking the World

It definitely feels like the end of a season currently - the pumpkins and rockets of early November have yet to summon frosts, but the wind is starting to get chilly, and the rain has been fairly consistent. I've entered a period I think I might call "the Gathering of the Canes", that time when all the tomato plants and climbers have died back, and the bamboo sticks placed in the spring can be returned to storage. Frameworks for the summer, their task done for now.

Charging up has either been ineffective thanks to cloud cover, short-lived as the sun gets lower, or technically risky with overnight (heavy)rains kicking up mud, threatening my dodgy wooden shelters, and putting the panels' claims of being waterproof to the test. One of my batteries doesn't seem to want to hit "fully charged" like it used to. The giant battery didn't seem to even register that it was hooked up to a panel, even in decent sunlight. My phone seems to be chugging through charge of its own accord.

To be honest, I've been getting a bit anxious about running out lately. The dry, sunny days of the year are definitely over.

But that, in itself, is an opportunity. Things are easy when our patterns are adequately supplied - but when the tide shifts, we can be grateful that we have space to shift with it, and seize the moment to pay attention to these changes, be curious, experiment, and learn for next time.

I'm finding myself switching into this mode, and as I do so I pick up on new thoughts.

1. As well as gathering up canes and clearing up plants, the season is still that chance to think through clearing up apps, data, and general technology usage. Say goodbye to networks you don't need over winter. Put projects into storage. Throw out entire top-level directories.

With my phone tied to the sun, I've noticed more how it acts as a go-between to my wider technology - all the cloud services and third parties it interacts with and relies on, all the weak and strong ties to people round the world. That's the modern world, it seems, but I'm in a position where I can use the way I charge the battery in my hand as leverage to really think through global networks.

Electricity powers a device. The device powers our behaviour. Our behaviour powers society. Repeat, reverse, unpick that.

The other aspect I wanted to mention is about experimentation, but I'll save it for another time...

Journal 2020-10-31: R(ain) & R(etreat)

Bit bleak for sunshine the last few weeks, as if the dry summer has suddenly remembered what the British weather is supposed to be like, and has spent a while catching up. Fortunately my medium-grey battery survived its overnight spell in a mini-storm, otherwise I'd be looking pretty low on juice.

As it is, and with life being pretty busy right now, I've reverted to 'the old ways' a fair bit. Phone's still good but my reader device lies fallow and I'm reading a lot of physical books currently. I've gone back to mains for the laptop though - just not enough opportunity at the moment to charge up the big travel battery.

But - as we approach the midpoint between equinox and solstice, it's a good time of year to take stock, start storing energy for the winter, and cut things back ready for the dark days. Some simple things you can do around this time are:

  • Hack back any phone apps, settings, files, and general usage patterns that you don't really need. Get rid of those games you haven't played in 6 months. Turn Location settings to 'battery saving' if you need them for COVID tracing apps. (I hear some countries have made the app mandatory now.) Give the screen a clean.
  • Stash any seeds from flower heads, fruits and herbs, ready for spring time. Make sure you decorate whatever you keep them in so they can feel proud.
  • Check through your cables for any duds - I spent 10 minutes with a USB checker and a battery, looking for low voltages and (mainly) loose connections. Use the same port on a USB battery each time for consistency, and give each cable a good wiggle to check if it cuts out - a few of mine got damaged when falling off roofs, for instance.

  • Spend some time among the changing weather - looking at it curiously from a window, standing outside breathing in the wind, or going for a walk to feel mud beneath your legs.

It's a beautiful time of year - every time I go outside there are yellow leaves carpeting the paths, and animals scurrying about looking to wrap up warm. The clouds are fast and bold here, riding on the chaotic winds belching out of the Atlantic.

Goodbye, summer.

Journal 2020-10-24: Reviving Past (Battery) Lives

It's blowing in a mini-storm outside as I write this. Unexpected-but-expected, the yellow warning came into my phone after it had arrived. Horizontal rain for a while, looks like it'll be blustery through til morning. Usually I'd bring my panel and battery in for this sort of weather but... Well, we'll see in the morning I guess.

Today's win has been a battery replacement on a 20-year-old rechargeable battery/speaker/rumble pack for the original Nintendo Gameboy Advance. I have a strange urgency to make this device work after seeing them on eBay, but the first one I got only half-works and the second one came with a leaked battery. The packet was sealed, so it's just what time and chemicals do when they dance, I guess.

But I didn't want to give up. I mean, come on, a Gameboy with a rumble feature? What's not to love? I could easily have stuffed 2 huge rechargeable AAs into the main GBA case, but it was a good opportunity to learn about replacing old batteries and giving new life to past tech. A few easy screws held the case shut, and the 2 battery packs were stuck down with old glue.

After checking the current type (written on the side, fortunately), I ordered in some Ni-MH batteries to replace like-for-like. Then I learned rapidly that soldering onto batteries is actually pretty tricky - they're slippery and prone to exploding of they get to hot, apparently, so I didn't want to risk holding my cheap iron on them for too long.

Two batteries gave the correct voltage, and electrical tape held them together, and eventually I got some success, and could merrily play Super Mario Land for a good while, vibration feature responding to thumps in the audio as I jumped down pipes and over bullets.

It's not perfect - the solder has come loose again, so I want to use some salvaged metal plates and... more electrical tape. But it proves it works, and breathes a bit back into decent components.

Revive the old, cos there's plenty of it out there just waiting to be enjoyed still.
