Wireless Car Alarm
This circuit is a wireless car alarm system that consists of two modules: a transmitter and a receiver. It operates on FM radio waves and is suitable for vehicles with a 6-12V DC power supply. A voltage stabilizer can be...
Low Power Wireless Audio Power Amplifier as baby mointor
This appears to be an infrared (IR) transmitter. IR signals do not penetrate walls, and it is assumed that this device is intended for use in a room separate from the one in which the user is located, rendering it...
LW, MW and SW bands Receiver
This is a compact three transistor regenerative general coverage receiver with fixed feedback. It's based on the principle of the ZN414 only much higher coverage. The sensitivity and selectivity is relatively good (especially on the LF and MW bands) as...
Schematic of The Infrared Rays Wireless Headphone
The transmitter circuit for inductive headphones must be installed on a wall or ceiling, limiting their use outdoors. This is a significant drawback of inductive headphones. In contrast, infrared wireless headphones do not have this limitation; their flexible infrared transmitter...
