Their has been some chatter at waterfuel1978 yahoo group about the ignition point as to the missing link to make the coil work ???

Here is a image to look at...

Today I build DC to DC converter Its output voltage can be controlled from 100V to 600V, using TL494 and emergency lamp transformer, I am having problem to
run using 330uF 400V capacitor when I connect this it starts heating transformer and MOSFET (due to low rating of Xmer), it gives good plasma blast with 330uF at first time but after some time it burned transformer primary and TL494, Again I assembled all to see whats the problem keeping bulb in series with circuit to monitor current, and found that after first blast TL494 makes duty cycle to 90% because of this it dosen't work after first blast, But circuit is good for low value capacitor 10uF 400V.

Below circuit is nice just adjust capacitor and resistor to high frequency and make ferrite core transformer, only problem of this circuit is it is unregulated output voltage. No heating of mosfet and xmer. go with this circuit. for real application, I used this circuit on my bike for one day no problem at all. with plasma spark power boost is observed...


Capacitor70,

All is clear in this circuit except MOV RDN240/20. What's that ? I cannot find it. Are you using  replacement for this ?

From the schematic I guess this RDN240 may be a bidirectional transient diode. Capacitor70, how is that diode rated ?

MOV is metal oxide varistor (http://en.wikipedia.org/wiki/Varistor). You can find it in a computer PSU. If you don't have one just leave it out.

hello!!! I'm new in the forum first time i post but have been reading it!!! my knowledge at electronics is rely basic nearly nothing... but i have good imagination ;D. i was wondering a different connection for the s1r transformer as in the schematic(http://C:\Dokumente und Einstellungen\Besucher\Desktop\S1r MegaTran 01.JPG) instead to connect the lamp wire at the ground connect it at the top of the spark plug so the hv from the coil fires the spark plug creating the bridge for 12v 6 amps or more depends of the limiter used,  ex 60w lamp so like that  hv+12v 6amp crossing the spark gap if the extra amps are the secret, maybe some one tried it already or maybe I'm talking pure bullshit :P any way tanks

I have spent a lots of my time to replicate the S1R coil...

But, I'm always failed...

Try Plasma Water Spark Plug...

You'll love it!!  ;D
