Raspberry Pi Computer: standalone “safe” machine

I want a computer that does not rely on a software service agreement to function. Cell phones obviously have to operate as a service since they need a network to operate. The phone is a gateway to the cell service. My kindle is similar for Amazon services. Laptops feel different to me. Computers feel like products. I own my laptop and I want to think of it as a standalone device, not a gateway to a cloud service.

Windows 10 is now a service. The future is clearly going in the direction of software as a service (SaaS as the kids put it). That’s fine, but I like to have at least some device that can’t be remotely bricked by a company.

Raspberry Pi Computer in a Box parts list:

Quick catch-up for other topics this week: I made a video I about sodium-ion batteries and people seemed interested. I think a sodium ion battery would be really cool. But I think the expectations of the youtube viewers may be a little inflated. Sodium is heavier than lithium. It yields less energy per atom, too. So it’s not going to be great for mobile. I made another video talking about that. So why bother with sodium? Lithium is relatively rare and expensive… so sodium might be better for stationary applications. It’s hard to say at this point, but I’m investing my time in an iron battery.
