Pretty sure I have posted this before, but has anyone ever seen the
flickering LEDs they use in tea light candles by themselves?

I just need the led not everthing else like the 2032 batteries or the
case
like if I bought them from a store.

The only flickering LED is a faulty one, the flickering is done by a
chip.

ISTR one of the science shows on TV saying that Philips discovered the
most
natural looking flicker was produced by driving the LED with a melody
chip.

I and some friends have a patent on making simulated fire light by
using random noise and filters to go from a a flickering candle to
the house burning down. Big fires look better with multiple channels.
I know it works fine in a small Freescale chip so you could a PIC or
any processor you like. It would be an excellent programming
exercise.


Are you one of those people who always has to use a microcontroller when
most people would use a simple circuit with only a couple of transistors?


Well if you see my last post you will see I found a source and much more.

One thing I found in my research was someone gutted a LED tea light and
it was one with the external chip. They hooked it up to a mini speaker
and it played "Happy Birthday". Seems they used surplus musical birthday
chips to make their fire.

I pointed out that they use melody chips 2 days ago.

Problably Disney sued, and they couldn't do anything audio with their "happy
birthday" chips.
I wasn't aware that Disney acquired the copyright.

Yes Warner does own the copyright, Warner/Chappell. Not Disney, not Time
Warner.

Seems to be some disagreement.

Opps Warner/Chappell or what ever it is now appears to be part of what ever
Time Warner is now.

Yea I figured all the company connections after I posted.Still its not
Disney. Disney did license it for a movie.

Flicker rate, intensity and light level were continuously adjustable
with 4 channels using a microcontroller powered directly from the 120V
AC line with no power transformer and did it on 2 mA. We tried it
"with only a couple of transistors" and it required far too many
passives with comparatively limited performance. I suggest a
micrcontroller when it is in fact the best way to do the job. And it
IS an excellent programming exercise.

Fair enough - but there's an awful lot of people about who always insist on
using a micro when it really isn't neccessary.
