Garage sensor. Uses distance sensors to detect door open/closed and car present /absent. Has buttons to open/close the doors, a 3v garage door remote. Also has a motion sensor, temp/humidity sensor and a photo resistor to understand outside ambient brightness.
Looking at building some fridge/freezer temperature and water leak sensors.

If you can pick it up in person in Markham, it's even cheaper. Bought a bunch of UPSes across a couple dozen years now, and replaced the batteries on many of them. Best prices I've found.
You are describing IPFS. If you install IPFS, then browse to some IPFS content (like a wikipedia mirror: ipns://en.wikipedia-on-ipfs.org/wiki/), that's cached on your system, if someone else requests those assets, your computer will help distribute it. You can "pin" content, keeping/seeding a copy.
