Joule Thief circuit shows 8x overunity

The circuit depicted in Figure 3-150 involves a contactor (KM1) that releases when the system is shut down. The contactor KM2 is energized, allowing a 220V AC power supply to flow through diodes VD1 and VD2, which serve as...

This system is designed to communicate or transmit a text message from one location to another using a wireless circuit. The text message is encrypted with a microcontroller, and the encrypted message is transmitted wirelessly. At the receiving end,...

Switching regulators operate by drawing small amounts of energy from the input source and transferring it incrementally to the output. This is achieved using an electronic switch, which functions at a predetermined frequency, acting as a gate between the...

This preamplifier features a built-in regeneration control that enhances gain selectivity. CI represents a single or multi-gang AM broadcast-band tuning capacitor, while LI is a ferrite loop antenna tapped at approximately 15 to 25% of the total turns. This...

The LM380 is a power audio amplifier designed for consumer applications. To minimize system costs, the gain is internally fixed at 34 dB. It features a unique input stage that allows for ground-referenced input signals. The output automatically self-centers...

The CS6061A integrated circuit is designed for touch-step dimming lights. It features a two-state female switching function and is reliable, capable of adapting to long cables and larger touch-sensitive pad loads (400pF). The collector circuit of the CS6061A utilizes...
