LED FLASHER
These 2 circuits can flash a LED terribly bright and consume but 2mA average current. The second circuit permits you to use a high power NPN transistor because the driver if a number of LEDs have to be compelled to be driven. The second circuit is that the basis for a straightforward motor speed management. See note on 330k in Flashing 2 LEDs below.
FLASHING 2 LEDS
These 2 circuits can flash 2 LEDs terribly bright and consume but 2mA average current. They need 6v provide. The 330k might have to be 470k to provide flashing on 6v as 330k activates the primary transistor an excessive amount of and also the 10u doesnt flip the primary transistor off alittle quantity when it becomes totally charged and so cycling isnt made.
