Blue Ring Tester Schematic Diagram Exclusive Hot! Instant

The Blue Ring Tester is a diagnostic tool for identifying short-circuited turns in high-Q inductive components, largely based on Bob Parker's original Dick Smith Electronics K-7205 design. An updated version, which features specific schematic details like the CD4015BE shift register and optimized R7 resistance, is currently manufactured by Anatek. Detailed schematics are available in the Blue Ring Tester Assembly & User Manual Flippers.com AI responses may include mistakes. Learn more Anatek Blue Ring Tester Assembly and Review HD

• High-value resistor dropper + smoothing capacitor to create a small DC supply (ultra-low current) OR use the rectified detector voltage as reference.
• Zener regulator (low-power, e.g., 3.3–12 V depending on circuitry) if a stable reference is required for comparators/ICs.
• Alternatively, use a high-impedance op-amp or comparator designed for high-side sensing with minimal supply.
