Bike Light Circuit PUBLIC

The Components within the Bike Light Circuit are as follows:

Resistors: 2x 33 KOhms, 1x 680 kOhms, 1x 82 kOhms, 1x 150kOhms
Capacitors: 1x 470 nF, 1x 220 nF
Transistors: 2x BC548, 1x BC 558
LED: 3x Polarised LED Lights

With the correct wiring and soldering of each component onto the Printed Circuit Board (PCB), the result will be a Simple Analogue Circuit which will pulse three High Intensity Lights (LEDs). The Pulsing is created through the correct placement of the the two Transistors (BC548). This correct placement creates an Astable Multivibrator which switches the LEDs on and off at a rate of one flash every 180ms (as shown in the Time Domain Image Attached).
The created circuit is a combination of both a series and parallel circuit formation. The LED Lights and the four Resistors (2x 33KOhms, 1x 680kOhms, 1x 82kOhms) are placed a Parallel formation while the Capacitors and accompanying Transistors are placed in a series formation.
