The iPhone 15 is a fantastic smartphone packed with amazing features. But you can make it even better with a couple of accessories. For example, how about adding a thermal camera or the ability to see into the depths of a machine?

What you need is aTopdon TC002C thermal camera and aUSB-C inspection camera .

Let's start with one of my favorite tools, the thermal camera. I've been using these devices for years -- I initially thought it would be a gimmick, but was quickly proven wrong. During the past few days, I've used my thermal camera to find faulty electrical components (they usually run hotter), uncover dangerously overheating rechargeable batteries, and discover binding brakes on a car.

The TC002C is an updated version of the TC002 that shipped with a Lightning connector.
