Picture of Needs...
PCB(above)
LED(small)
510ohm resistor
3v flat button cell battery
Thin wire
can u plz tel me why particularly u selected a 510ohm resistor only...and also tel me why particularly u selected 3v flat button battery only and also help me with how to select resistors and batteries for any different simple projects

I used a 510 ohm resistor only because it will make the led light up at the brightest, also I didn't use a 3v button battery, i used a 9v. I used the 3v button battery because it's compact, and you dont need a resistor when you use a 3v button cell battery.

i made one of these as a fish lure once. believe it or not it works under water.
i didn't have to glue the electrode wire or solder them onto the cell.i used a little pressure from the plastic case i used. have fun....

wow! did you catch any fish?

The flasher LED attracted fish. Catching the fish required knowledge of bait and lures. I am working on another attractor- a buzzer. It is a miniature relay connected as a buzzer. Hope it works.
