build 5v power supply

build 5v power supply

Simple 5V power supply for digital circuits
This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall tranformers with variable output voltage are available from any electronics shop and supermarket. Those transformers are easily available, but usually their voltage regulation is very poor, which makes then not very usable for digital circuit experimenter unless a better regulation can be achieved in some way. The following circuit is the answer to the problem


Building the 5V Regulated Power Supply
a stripboard layout for the 5V regulated power supply shown in figure 4. The layout does not include the transformer block, so the input to the board needs to be 7 - 35V AC from a suitable transformer. The layout includes space for two optional 2-way screw terminal blocks to make connecting up the power supply easier.

he FM modulator circuit is built with a Motorola MC1648P oscillator. Two varactors, Motorola MV-209 are used to frequency modulate the oscillator


FM Transmitters: FM Modulator & FM Transmitter Circuits
FM (Frequency Modulation) refers to a type of transmission method where the actual broadcast frequency deviates slightly once "modulated" with audio input. Therefore, FM transmitters are frequently referred to as "FM Modulators". Here's some FM modulators that will allow you to broadcast on the FM frequency band.

FM MODULATORS
In the circuit diagram of LM566 FM Modulator unit shown in Figure 12-1, what will be the DC bias voltage at the input of LM566 (pin 5), if no DC input is

fm transmitter circuit

fm transmitter circuit

FM Transmitter Circuit
An low power FM Transmitter using an op-amp as the audio preamp and a single transistor as the RF amplifier.

FM Transmitter
Here is the schematic, PC board pattern, and parts placement for a low powered FM transmitter. The range of the transmitter when running at 9V is about 300 feet. Running it from 12V increases the range to about 400 feet. This transmitter should not be used as a room or telephone bug.


FM Transmitter Circuit
This circuit is a simple two transistor (2N2222) fm transmitter

. No license is required for this transmitter according to FCC regulations regarding wireless microphones. If powered by a 9 volt battery and used with an antenna no longer than 12 inches

HARTLEY OSCILLATOR

HARTLEY OSCILLATOR

The Hartley Oscillator is characterised by an LC circuit in its collector. The base of the transistor is held steady and a small amount of signal is taken from a tapping on the inductor and fed to the emitter to keep the transistor in oscillation.


The transformer can be any speaker transformer with centre-tapped primary.

The frequency is adjusted by changing the 470p.
