How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Help me identify possible tracking device found in my car

TL;DR

I found a non-OEM electronic gadget in my car. It is wired into the ignition, and contains a 435.10 MHz radio reciever, a microcontroller, and two relays. I suspect it might be a device that allows third parties to unlock the doors and start the car with a radio.

Details

I was driving my 2020 Honda Insight EX when it started to make the annoying sound of an electromechanical relay rapidly switching on and off. When I got home I looked under the dash and straight away I could see someone other than Honda had been in here. The first thing I saw was this surface-mounted switch that doesn't belong there.
