Blip! - The LED flasher.
Micropower LED flasher
Powered from 3V (e.g. CR2032 or other 3V coin cell) via J1 (square pin is pin 1 - positive).
LED is through hole (for best results use a low current led e.g. Vishay TLLK4401).
Square pin of LED1 is anode.
Flash duty cycle is 10.5ms/1.4s = 0.75%
Power consumption estimate calculations given in schematic.
Resistors ideally should be 1% although BAW56 double diode does contribute to imprecise on-time.
Schematic is in svg format file at Google Drive link.
