(number 9)
The new version is running !
This is a seven power filaments coil, plus the trigger.
But i ordered a six transistor board, though... Next board will be with seven transistors and all of the seven will be selected to fire as near as possible, as explained at the "Intermediate Guide" from P. Lindeman
This system is now running at 30Km/h what means about 74 pulses per second at the coils.
Now about the position of the coil.
The Linderman video showing how to build a Bedini SG kit shows the central protrusion of welding rods to be turned down, in such way that the coil's holding mechanism attach to this protrusion. This is pointed by the red arrow below:
Also in the video where J. Bedini shows how to build a multifilar coil the top of the coil is the flat side, where the rods are not protruding from the spool:
But for me the system seems to run much easier by inverting the site of the protrusion of welding rods, like this:
With this arrangement it much easier to reach the situation showed at the image blow, where the oscilloscope image has only the 'h' curve:
With the rods core protrusion facing down i was unable to reach that pure 'h' shape at the oscilloscope.
Allways there are this extra pulse marked by a blue dot at the image below:
If someone could teach me that this extra pulse do not matter...
And one can notice that my system can run with both core rods configurations, poitting top or bottom:
