Hello everybody,
I am lokking for a PCB design for my idea.
When 12 V is applied, blinks a 12 V bulb five times (approximately 1 Hz), then stays continuously ON until power is removed.
I asked ChatGPT and its drowed graphical schematic for me. My electrical knowledge is very basic, but I can solder the components if I have the PCB.
Can anyone help me to draw a PCB for this circuit. There is what ChatGPT did in attachment. I am not sure it 100% correct, please fix it if needed.
It would be fantastic if I can adjust the blinking time.

Thanks in advance!
Zoltan

You don't mention your application? However, what you describe is popular for motorcycle brake lights. Should that be the case units like this can be had for about $7.00 USD, like this one for example. I use one on my bike that offers several flashing options. I forget who made it and it sits under the seat of my bike.

Hi Ron,

Thank you for your reply and the link. It is great and this is what I need. There is a middle brake light on my Maserati diffuser. I want to make it to blink.
I already order it. Thanks again.

Hi sghioto,
This looks great thank you very much! I see you added the extra feature to change the timing.
As you can see I already ordered a deviece, but definetely I will build this one too.
Many thanks
