Let’s Clone a Cloner - Part 2: You Have No Power Here

This blog walkthrough details building and debugging a long-range RFID badge cloner using an HID MaxiProx reader, with emphasis on diagnosing poor read range caused by insufficient or unstable power. The author explains electrical basics, tests series/parallel battery configurations, measures current draw for the MaxiProx, buck module, and ESP RFID Tool, and ultimately achieves substantially improved range using a high-capacity 100W USB-C power bank; the piece is a technical how-to and does not report an active security incident.
