Single AA battery to light WHITE LED for long-long time

Okay I will double check my circuit.  Thank you for going back and reconstructing it and posting the photos.


@sanmankl

I think normally adding more LEDs should increase current consumption. Adding more LEDs without increasing current consumption might happen, if the aggregate brightness reduces by an exactly proportional amount.   This is just a thought though.  The results you were getting are interesting, I look forward to hearing more about your results.

A spark gap from 2 dissimular metals like graphite and copper
produces a galvanic cell when a spark ( plasma) jumps.
The spark acts like the electrolyte in a normal battery.

This way you have a "galvanic battery" in series with your circuit and
can draw "free" electrons from it, which come into your circuit and will
recharge your battery.
You are probably using up the graphite and the other metal due to
oxidation and corrosion, but this is the source of free electrons which will
charge up your batteries.
Quite simple, if you have understood it.
The same effect is true in all the Newman machines, that used big sparking
commutators from copper and graphite brushes..

This way also a direct conversion of graphite can be done to electricity.

Hi Stefan,

I'm going to try and build a simple micro-gap using two pencil graphite rods, as Marco outlined, spaced by a "hair". No microscope here so it'll have to do for now, but hopefully something actually happens when it's plugged in...

Okay, if just 2 pencils do not work,
then try pencil onto copper.
Or pencil onto lead solder.

Here's my attempt at creating a miniature spark gap using two graphite pencil rods. I used a hair (thankfully I still have some left on my head ) as a spacer between the electrodes, and wrapped tinned 34 AWG wire around the other ends, then hot glued them to a small piece of plexiglass.

So now what do I do with it because from what Marco said we should either pulse the coil or use the spark gap but not both?
