Take a trip through two parts of the electromagnetic spectrum, first with radio (RFID) and then visible light (film).
We’ll start with an introduction to Radio Frequency IDentification (RFID) tags/cards/keys. How do they work? What shapes do they come in? What frequencies do they operate on, and what chips will you find inside? Then, we’ll take a practical look at cloning some common ones.
Next up, the visible light part of the spectrum. Before camera phones, film photography converted light into a lasting record of a moment. First, we’ll take a quick look at the evolution of film cameras over the last century. Then, stepping back into the twenty-first, we’ll look at currently available film formats, processors, and how to get started reviving a cheap antique camera. It’s easier than you think!
