I'm thinking of trying a 'delay off' function on a mod I'm building. That is, when the momentary button is released the atty will continue functioning for 4 seconds - before switching off (or, ideally, fading out)
Reading around on the net, I understand that a simple resistor/capacitor circuit will achieve this (without the need for an ic such as the 555 timer).
Can anyone with electrical knowledge suggest which resistor and capacitor I would need to use with a regular 3.7v battery and dual-coil atty? The end result should be 'instant on' and 'delayed off'.
I've seen some very basic circuit diagrams with this mix - used to power leds... but an indication of wiring for atty (only) would be appreciated too.
I hope someone can help.
