The indicator LED doesn’t work either, so I’ve got to debug that. One more interaction of the PCB and I’ll have a working version 1!

Each version includes something new

Not to mention the injuries. I hope they just get banned and let it be an end to it. Another semi-pointless ritual that’s maintained for the same of maintaining it.

And for what? The same display, year in, year out. Bang! Bang! Band! I lost interest in fireworks when I was about 30. It’s just the same stuff, year in year out. Drones, however. Now they are amazing!

The tap is now straight and doesn’t wobble. That would have been easy to do right the first time. The bathroom has no floor when I installed that base 🤷‍♂️

Not great, but a vast improvement. These cross timbers have reduced movement significantly. Should be good enough.

I remove the lower board. It was held on with a nail. FML. Need to secure this now, somehow.

Thx. That’s what I eventually did. I’m learning. Slowly :)

Changed my perspective completely. I’m now all about environment and less about “do this and do that”

The Carpenter And The Gardener by Alison Gopnik. A very interesting journey through modern child psychology. As a parent, it made me re-evaluation how I was parenting my kids.

My heat pump simulator is now connected to my energy manager. I spent some time getting to grips with the parts list and rendering the device types. You can see the heat pump parts alongside my Tiny Dishwasher.

Next step is generating getting the heat pump to generate an energy forecast.

Looking at this again. I have finally figured out some of the PartsList stuff in Matter. This is my Heat Pump Simulator showing the few "Devices" that make up a heat pump.

That freed up over 300GB. That's a lot of unused docker images.
