Makes sense!
I would have installed a larger array myself (for the same winter reasons, only here cooling in summer is the biggest power draw). But to do that I would have needed to request a 3-phase power line and there were no good 3-phase native battery systems back then to fit my case.

I concur. It does feel great. Simple, modern, efficient, and most of all: the right thing to do.

Interesting.
My house is 275m2, 11.7kW array with 9.7kW inverter capacity: as big as it is allowed on a single phase power line. On a cool day I may use 12 kWh. But on a hot day, to keep 23C it can use up to 45kWh.
Can I ask why you oversized your system that much?

Cheers. In my dreams I wanted a passive house… but they are nearly impossible
to find!! I tried to budget how much it would cost to improve the house insulation (to reduce my self consumption) but that would have costed many times more than just oversizing the solar array and battery system!

The “everything else” includes
* hot water
* cooking
* dehumidifier
* laundry/dryer
* working from home
For comparison, how big is your house? Do you have gas furnace/hot water/stove? Do you work from home?

That accounts for everything. My house is not connected to natural gas line, and it’s not particularly well insulated (as most Australian construction).
Cooling ~380 kWh
EV ~130 kWh
Swimming pool ~60 kWh
Everything else ~345 kWh

Italian monks where making magnifying lenses in 13th century. My guess is DIY fabricating optical elements is waaaaay easier than DIY semi. And by that I mean it may still be bloody hard :D

Lately I have been struggling with the thought that my designs (in my hobby project) will never be used but anyone.
It used to not bother me…

Plinky looks a remarkable feat! Kudos for that.

Nice! Yep similar motivation then!
I am fighting burnout lately. I haven’t posted anything in months.

Thankfully I don’t have to, it’s a hobby project! But, if I’d ever have to commercialize it, NVIDIA GPUs are the de-facto standard in any VFX/animation company I have ever seen 🤷🏻

… and that’s why my hobby renderer is implemented in CUDA instead of Vulkan.

One of the problem with VR is that like 40% of the population feels some degree of motion sickness that makes the experience from mildly uncomfortable to flat out unbearable… I am in the severe end of the spectrum, like I can feel sick in seconds and be useless for hours after that.

Doh! Then there is really no excuse whatsoever.

What’s in the scene? I’m curious.
I couple of years ago I did some work on my project to optimize scene graph creation and common operations. If not done carefully, it’s easy to have quadratic or even cubic algorithms in this part of a program.

It sounds that for longevity, both solutions prefer to manage 50% total power delivery. I guess it’s a variant of the glass half empty, vs you can only drink half of a glass full :)

It’s interesting. Lead acid batteries likes sitting charged at near 100% and dislike being discharged below 50% as that behind degrading the components.
Lithium batteries last long when not charged full (likes to sit at 50%) and can handle the occasional near full discharge.

I started from ImNodes, which wasn’t complete for what I wanted to do, but was simple enough for me to make it my own and start rearchitecting and implementing what I wanted to get out of it.
If you want a turnkey solution, you probably find other feature reacher libraries.
