Hello everybody,
My sister loves taking care of here nails, and she bought an UV lamp to dry gel nails.
This little device lights up a UV led for 10 seconds. But it needs to light up at least 1 minute.
I thought there would be a 555 timer in monostable mode. But it isn't, I think it isn't the pinout is not correct.
It is a sop8 package.
I've drawn a schematic (I know, it's ugly).
Anyone who knows what this chip is and how I can modify the board so that the UV led lights up for about a minute?
Hope someone can help me with this
Regards Thomas
