Current-to-voltage converter

This DIY 12V to 220V DC to AC converter utilizes a CMOS 4047 as its main component, effectively transforming 12V DC into 220V AC. The circuit design of this DC to AC converter primarily revolves around the CMOS 4047 integrated...

Using a circuit similar to the LF block converter, a Schumann Resonance Converter has been developed to shift near-DC signals up to approximately 2 kHz for compatibility with a standard soundcard. The initial test results indicate successful operation, with...

The D169 functions as a level detector, offering complementary outputs. An operational amplifier (op amp) is employed to integrate the input signal Vin, utilizing a time constant defined by the resistor R1 and capacitor C1. A negative input signal...

When the power supply is connected to IC1, the output pin 3 operates at a frequency of 1 kHz. The components Q1 and Q2 work in a push-pull configuration. When a positive output signal is generated, Q1 and Q2...

This converter allows the reception of frequencies ranging from 800 to 1000 MHz on any scanner that operates within the 400 to 500 MHz range. The converter can be configured to cover either the 800 to 900 MHz band...

This is a 35.3 to 10.7 MHz converter circuit. It converts the 35.3 MHz signal coming from a VHF/UHF tuner down to an FM tuner to decode the TV audio in FM. The 35.3 to 10.7 MHz converter circuit is...
