Thanks for your effort and video. But if you clean your soldering iron tip your soldering will be very good and your product will be more interesting. Good luck.
Check the latest video you will get the difference 😄
Thanks.
@@BillionGearOk, best wishes.
Where i can find ic555?
What board types?
It is 8 pin 555ic
You can buy In electrical shop or at amazon.
what is the power supply
4-Voltage D.C. Power Supply.
@@BillionGear NOOOOOOOOOOOOOO MIN VOLTAGE FOR STD 555 IS 5V
DID YOU READ THE DATASHEET
very fragile
the 555's supply voltage operating range is +4.5 volts (minimum) to +16 volts (maximum). It is specified for operation between +5 volts and + 15 volts. The 555 can work perfectly fine at 12 V, and the SE 555 and other CMOS versions can handle 18 V....
So this thing is FAKE
Circuit is 100℅ True. And for the input voltage of 555 ic is +5v i know that. But for small circuits like this if you will supply 3v or around then it will work perfectly.
Remember , not to overload any circuit but its ok to make a less input to this circuits it will be more safe. And for this particular circuit i can say 100% that this circuit will work on the voltage stated in the video.
