Simple Infrared Remote Control Extender
This ultra-simple remote control extender is ideal for use with a hidden video recorder. The recorder is a Panasonic NV-SD200 and is employed as part of a camera surveillance system. A PICAXE-08-based circuit detects events and controls the recorder. Additionally,...
relay Do I need a protection diode here
An automotive relay is being analyzed, which exhibits a more complex wiring configuration than typical relays. The diagram indicates that the B/G line maintains a high signal if certain conditions are met, specifically when the engine temperature is excessively high,...
Homemade tablet CarPC
The momentary hold relay board and the accessory delay module are components designed for automotive applications. The momentary hold relay board powers the GPS unit and the tablet, eliminating the need for manual button activation. The accessory delay module is...
light activated relay
This circuit is similar to the previous one but incorporates a photoresistor to trigger the flip-flop instead of a push button. A bias resistor is placed in series with the photoresistor to ensure that adequate voltage is present at the...
remote shift light
Replacing the resistor/transistor with an n-channel power MOSFET and substituting the relay/protection diode with a light bulb results in a simplified circuit that mirrors the original design, provided one end of the light bulb is connected to +12V. If the...

Remote Control Toy Car Schematic
The following circuit illustrates a schematic diagram for a remote control toy car. Features: it does not affect the performance of the original design.
The remote control toy car schematic circuit diagram typically consists of several key components that work together...
Infa-Red Remote Control circuit
This remote transmits a tone using an infrared LED. This tone is decoded by the receiver. Since the receiver only switches when it "hears" the tone, there are no accidental activations.
The described circuit consists of a remote control unit and...
remote control receiver circuit
The circuit consists of an infrared transmitter-receiver pair that uses infrared beam transmission to switch the toy car on or off. It can be modified to allow the toy car to turn left or right. To operate the toy car,...
