In Topic: LED Strobe Trigger For Olympus OM-D E-M1 Mark II

I can read R4006/1302 on one of the packages (the one adjacent to the one marked "f2m"). There is another small 8-pin package on the other side but as far as I can see (with magnifying glass) it does not have any marking....

 

The R might be a P and then this might be P4006 which is actually a code for another (older?) IGBT from RENESAS with very similar specs. https://www.renesas....jp4006ageds.pdf

It is hard to say given these pictures given enough of the circuit card is obscured by the black tape. That said I strongly believe something similar could be done given most strobes use more or less similar implementations (e.g. IGBT, etc).

 

 

 

Trying again (was away on a trip so did not have the LM2 under my hands). Hopefully pictures w/o tape would help.

 

Any suggestions on where to start (my electronics knowledge is minimal) would be great

 

Thanks!

Hi, cool idea!

 

I am wondering whether a similar mod can be done to the FL-LM2 (the smaller flash of Mark I OM-Ds). Anyone with electronic background can comment on whether this mod will work?

 

If it helps,  I disassembled my older LM2 and attached photographs. As far as I can tell, the xenon tube assembly is similar to that of the LM3. Any suggestions how to proceed will be appreciated...
