I have a new product I invented. It's a LED fish strike indicator.
As I found out experimenting with LEDs, getting the proper current is
the key. My product uses two 5.8mm dia. button batteries. I first used
two #10 air zinc hearing aid batteries (1.4v, 90 mAh) but found out
they only last 90 days after you pull the tab off whether you use them
or not.
I now am going to try two Energizer # 379 type alkaline, (1.5v,
14.5 mAh, 5.8mm dia.) Do you think these will work powering a wide
angle red LED or similar type without eventually frying the LED? The
air zincs are working and I have, so far , not fried any LEDs with
this setup.
I don't want to use a resistor because the unit fits on the end of a
rod tip and I must keep them as small and light and as easy to
manufacture as possible. The units will be powered up only
intermittently, maybe only a few seconds at a time, as a strike is
being detected. I know I am exceeding the current but I don't think
there's enough juice in these little batteries to kill them. But I
don't know.
The color is not that important so if a different color would work
better that's ok.
If you have any suggestions for me It will be greatly appreciated.
