Sorry you don't understand, you can skip the part of the video where I talk about the sponsor without any problems. The circuit diagram and PCB remain available even for those who don't watch it or the full video... but remember that it was thanks to that sponsor that I was able to share, for free, several dozen fun PCB projects to assemble.
I'm starting my journey with this IC and I learned it can stand 200mA of current passi ng thru. Seeing your circuit has no current limiting resistors I'm wondering how it really works... 5 paralel links witj each 2 diodes in series definitely exceed these 200mA...
True, but I would not have been able to put it while keeping this fine PCB design, I will use a potentiometer in a more advanced version of this project
- Bien, tal vez pronto haga una versión con transistores, pero con más de 50 LED para cada canal. - Right, maybe soon I'll do a version with transistors, but with 50+ LEDs for each channel
Gee your police lights are so neat compared to mine. Stefan you're a perfectionist! I like your videos. You put a lot of effort into creating good content. Keep up the good work.👍🏻
Great project! How would you get the flashes to overlap on each side? To explain better = red flash overlaps blue flash by a few milliseconds. Thanks!😁
Thanks! the capacitors are responsible for regulating the flashing frequency of the LEDs and the exchange rate between the red and blue LEDs, and thanks to this configuration with the two NE555s I can switch the flashing frequency of the LEDs between the two groups
I built the circuit according to the schematic, using 4 LEDs on each side. The LED's do a "blink-blink" at the same time on both sides, not alternatively!!! I checked the circuit many times. Are you sure the schematic is correct?
@@Stefano91ste Found my problem. The LEDs on each side were in the same direction. This actually is not a bad circuit. This way, both sides do a blink-blink at the same time, which could serve as a double-warning set of lights. Yours is much cooler, though :) Thank you very much for your reply and this awesome circuit! Wish you great health and happy tinkering with ideas.

Wish you great health and happy tinkering with new ideas.
सर ये सर्किट मैंने बनाया लेकिन पोलीस लाइट मोड कूच डर चालणे के बाद रेड LED 3 बार blink होती है लेकिन ब्लू led 1 हि बार blink होती है ऐसा क्यू क्या इस सर्किट को रिसेट करना होता है तो कैसे करें प्लिज बताइये।
555 is my favorite! Motorcycle police should attach these to their helmets. 😆 May I make a small request? Could you maybe do more 5v designs? Almost all the things I make use 5v so they can be powered using a USB power bank. Just makes things a little more convenient. :)
@@frankcaccamo3568 Hi, it's not a kit but a PCB designed by me. In the video description you will find a link to download the PCB files, then you can upload those files to PCB manufacturers like JLCPCB and order your boards. (without components)
Hi Stefano91ste! This is exactly what I was looking for, however I would like to run a total of 12*3mm LED (6*Red and 6*Red) from a 7.4v 10400mHA Li-Po battery (RC Car) what would I need to change on this to make it work?
Hi there... I tested this out on my every circuit software. I did exactly the wiring routing correctly. I did not hook the number 4 to 8 yet just to see if it works... when I turn it in. The timer greyed out. This mean there's no going in the number 4 pin. I don't understand why it works in your video... the software requires you to hook the number 4 pin with number 8 together then it will power on. This is so weired..weird... I guess I gonna have to try another app on my phone. The light did not come on... I don't know what is up to with it...

Hi, you need to post videos on RU-vid that people like and get subscribers to the channel. When you have reached a good number of subscribers, the sponsors will look for you😁
Are these boards available to buy without LEDS installed ? I am not looking to do programming myself. If they can be purchased already programmed can someone contact me. Thank you
Hello sir sir please help me my red led is not blinking but blue led is perfectly blinking please help me sir 🙏 please reply me sir 🙏 Please reply sir 🙏
For the 12V it is fine without modifications. 5W LEDs cannot be used because each NE555 can deliver a maximum of 200mA, you should use power transistors and the circuit should be completely redone.
Hi, it is actually ready to work at 12V - towards the end of the video I explain that to use it in the car with 12 / 14V and for long periods it is necessary to add a heatsink to the two NE555 ICs.. however using it in the car on the road is illegal, know it and do it at your own risk
Hi, yes of course! 1) Download the .rar file from this link: bit.ly/3jwpeU7 (it's the same link I shared in the video description) 2) Do not unzip the file, it is ready as it is. 3) Go to jlcpcb.com and create an account if you don't have one. 4) Click on "QUOTE NOW" and upload my file on the next page. 5) Follow my video from 1:55 to see the whole upload process. 6) You can choose the color you want for the PCBs, it doesn't change the cost. Then choose a shipping method, indicate a shipping address and a payment method.
