The joule in the crown!

[TinselKoala]

There is so much electrosmog in my environment that sometimes LEDs that aren't connected to anything at all, will glow dimly but easily seen. So I am really not too impressed by LEDs that are so dim you can see the anode wire inside the LED, connected to a bunch of circuitry including capacitors and coils. When a 9 volt battery enters the picture, it's nearly time for another alt.snakeoil Video Report.

Show me some LEDs that are bright enough to read by! If it runs on a single depleted AAA battery for only ten minutes at that brightness, that is good enough for me, because it is genuinely useful. An LED that glows dimly for a long time is interesting from a theoretical point of view... but more interesting to me is an LED that glows while connected to a capacitor that is _rising in voltage_ even though no power source is connected, as I've demonstrated.

Your mileage may vary, of course.

Now i'm getting depressed over joule thief before i sleep.
