► $2 for 2-Layer PCBs & $7 for 4-Layer PCBs: jlcpcb.com
In this video we see a simple circuit, based on two NE555 that is able to reproduce the effect of the lights of the Police Cars, all made on a fantastic Black PCB.
After trying the excellent service offered by JLCPCB I recommend it, the quality of the PCB is high, customer service is always available and professional, the time of realization is short and the delivery of PCBs is by express courier. JLCPCB is a great place to get hight quality custom circuit boards at an extremely low price, you can buy 5 PCB Boards (Any Color) for 2$ !!!
Components:
- 2x NE555 [ bit.ly/2QTemmJ ]
- 20x LEDs 5mm [ bit.ly/2UzRDgR ]
- 2x 850 KΩ Resistors [ bit.ly/2ytgn3e ]
- 1x 1uF Electrolytic Capacitor* [ bit.ly/2WlIgCt ]
- 1x 100nF Polyester Capacitor [ bit.ly/30xHDbJ ]
- Heatsink: [ bit.ly/30mKYdR ]
- 9V Battery Clip [ bit.ly/2SrU0Sd ]
- PCB: (Ready for jlcpcb.com): bit.ly/3jwpeU7
*Don't use my PCB for profit or sponsored videos.
Power with 9V DC and use 25/50/100V Electrolytic Capacitor
For any other questions you can ask in the video comments:)
