My s1r9a9m9 replication!

[Shanti]

Well somebody in the yahoo groups forum just found this patent US 6553981 (get it at www.pat2pdf.org)

Well, it's exactly what we have here...

It even describes the different spark plug configurations and also different circuits versions (e.g. Circuits without the diodes and just with the coils for blocking, or with snubbers, etc, ...)

See one example here (They just have a CDI System for ignition):

the story repeats it's self...

Someone should protect this to be public domain like linux.
Maybe we need to stop and think about this...

Well the patent is from 2003 so never mind what I said.
This Sunday I realised that electrolisers are old news. A 50 year old basic school and non internautic guy that I know, knew about that from along time ago...


Capacitor70 thank you for your help once again,

My cap really shorted,
After taken the cap out of the circuit I measured  0hom between the two terminals of it.
Before he was farting like a pig well it was making the same sound of the spark plug.
It is swollen too.
Good thing that bulb! ho ever thought about it had a good idea.
I will check bridge and every diode.
By the way, since I couldn't got 6Awhatever diodes I'm using 19 diodes BY229   8A 800V rating

I got myself 4 330uF 200V cap that I'm going to connect 2 in series and 2 in parallel so the final cap is a 330uf 400V.

Computer power supplies are a good source of this caps. Computer monitors too!

Keep up the good work people

Cap 70,  you answered all my questions earlier very well.  I have one more though.
When you were talking about the CDI box.  I know what a CDI box looks like, i have worked on motorcycles and 4-wheelers for years.  My question is:  What does a CDI box do in laymens terms.

The way i think a motorcycle runs it this,  Flywheel with magnets turns around stater which puts out a small spark, this spark runs up out of crank case under gas tank on most motorbikes into small CDI box, which does and then a wire from here goes into coil, which jumps small spark up into "knock your di%# in the dirt fire" which in turn goes into the plug.

So does the CDI make the thing fire at the exact right moment or what?
