LED circuit-no R's, C's, T's, - ONLY A White GLOB??
LED circuit-no R's, C's, T's, - ONLY A White GLOB??
(OP)
I am wondering what the hard white glob is on the LED flashing circuit in my bicycle LED flasher. It seems to take place of the resistors, capacitors, and transistors in a traditional LED flasher. I am wanting to use this same technology for an idea that I have... I must also disclose that I am a caveman mechanical engineer...I know that there is some electrical engineer that would love to verbally kick me around in exchange for the information that I seek. Any help is greatly appreciated.

There may even be bare IC with bond wires visible.

It is likely just some potting compound of sorts for protection from the elements. You could attempt to cut around it and you will likely find standard components underneath.

if it is larger than 1/2 inch, it covers discrete circuit
if smaller a "flip-chip" IC. ( An IC with BUMPS instead wires directly soldered to the PCB)
Most likely it is a special custom IC which is cheap to use
and expensive to develop.
