Hi All;
I'm new to the group and play with electronics for hobby.
I would like to know if I can adapt the oscillator #3 circuit to run on 12-14V, using a LM555CN timer, R1=470k, R2=4k7, C1=4.7uF, one 2N2907A, three 2N2222A, and three 3W LEDs?
My aim is to strobe the LEDs for 15ms every 1.5s
I think for 15ms I could get away with up to 3A through each strobe, giving a nice bright flash without reducing the life of the LEDs.
If the above is possible, do I need to put a resistor between the output and the 2N2907A to protect the 555?
Thank you for your help,
Mark
