Help me reverse engineer this led strobe light?

[justanotherengineer]

Hey guys, my first reverse engineering project ...not going so well. Here is a picture of the front and back of the circuit I am suppose to write a schematic out of.

I don't need the entire thing, I just need a little help starting >.< Thanks

as stated its a double sided board I'd start with the power lines trace them out first then join the components in
your first draft will be rough
don't give in keep trying


it looks familiar. anyway goodluck


theres a pcb number in the bottom left hand corner of your pic
you could try a web search using that number

T1, T2, and T3 are transistors (I can't tell you what kind with out the numbers). I assume you know the rest of the parts? Let me know if you don't.

You just need to trace out the circuit. Find where each pin of each component is connected. It looks like a two layer board, so you should be able to do this by looking and tracing. An ohm meter is helpful too to test of parts are connected.

Just draw it out as best you can. Use generic symbols for the transistor if you don't know what they are ... then figure those out later. It will probably be a mess the first time you draw it. Sometime it takes me three or four iterations of the schematic to get it looking nice.

Good luck and hang in there.

If there are components and/or symbols you need to identify, add more details to your question and let me know ... or send and email and we can converse that way.
