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

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.
