NFC Round Visualizers By Midwest Gadgets

The Midwest Gadgets Field Visualizer Ring (RRV1) is the most satisfying NFC field testing tool I've ever used — 6 LEDs, round form factor, and it actually dims as the field drops off. This is a must-have for any hardware hacker serious about NFC range testing and field mapping.In this video I'm breaking down the Range Ring Visualizer from Midwest Gadgets — what it is, how it works, and why it instantly became one of my favorite bench tools for demonstrating NFC field coverage. Whether you're testing a Flipper Zero NFC reader range, an NFC relay setup, or just want to visually understand how near field communication fields behave in 3D space, this tool shows you what RF meters can't.🔑 What makes the Range Ring different:
6 LEDs in a ring layout for intuitive directional field sensing
LEDs dim proportionally as the NFC field weakens — not just on/off
Compact, portable, no batteries to fuss with
Exceptional teaching tool for showing NFC field shape and dead zones
