You’re right in that running HA just for a WoL timer would be silly, but (presumably) it’s already running for other, less silly purposes.

I’d say the main benefit is when the machine requires regular (as in daily) reboots, or if it’s something you don’t trust is fully private and want to be powered off outside work hours. Not useful for me, but I can see why it would be handy.

I remember seeing someone combine the two and had Home Assistant pull the photograph from USPS and attaches it to the notification when the mailbox sensor is triggered.

I’m mildly surprised OP’s laptop keeps the bluetooth radio powered up while asleep, but I would be a lot more surprised to find one that doesn’t work with USB HID.

That isn’t even a terrible idea - with that many conductors, you should be able to carry tens of amps. Use two for “Data” (detecting charger) and you’ve got… 21 positive and 21 negative. I’d not be surprised to see that hit 100W without catching fire.

How many people actually want curved walls though?

People who hire fancy architects. Not people who have to work for a living.

It depends on what you’re building. If you want a normal rectangular house, 3D printing will be incredibly inefficient and pointless compared to traditional framing techniques.

On the other hand, if you want curved walls, traditional framing becomes incredibly complex and expensive, whereas 3D printing takes exactly the same materials and labour regardless.

I think 3D printing an entire house is just a gimmick, but it will still be an incredibly useful tool, even if only used for simple things like making rounded foundation pads or retaining walls that follow the landscape or curved hallways connecting modular buildings.
