Experimenting with a pulse generator
« on: August 13, 2018, 11:09:08 AM »
Experimenting with a pulse generator for ignition coil says it all. I purchased it off Ebay some time back for $2.00 to play with. It was a hot very humid day so I played with it to see if I could get it t work as an ignition coil. It will throw a nasty spark at 1.5v "D" battery to 12v lantern battery.
Any way here is a video of the experimenting I did with it.

Well I have convinced myself that they will last a considerable time I've ran it on and off for about 6 or 7 hours and still seems to be the same. Longest non stop run was 45 minutes. So I went ahead and milled pockets in the motors base for the battery and pulse unit. I wired it to a power switch and added a LED power on light and a charging port for a USB power cord. I think it's going to work out alright for me.

I had a comment that it looked like the motor was harder to start with the pulse unit. So I did a short little video oof starting to let you be the judge.

One last video of the Six Cycle engine running with the pulse unit. I put a lighter spring on the gov to slow her down. It will now be put back on the shelve for now.

  Ran the engine on and off a few time the pulse generator still preforming as it should. I added one to a TM-6 unit that I put together and preforms nicely at 4 volts.

I did get the other style of HV generator that I was going to give a try. It will not work as an ignition coil as it is to slow it has a pause to charge up and voltage isn't near as high as the one I'm using on the engine.

  Just an update the unit on the 6cycle slowly died. I'm hoping it was heat that killed it as I had it in a small compartment in the bottom of the base. It just slowly got weaker until it wasn't strong enough to work correctly. So now I'm going to create a pocket in the top of the base and attach a heat sink plate to it and see if that will work. It did last quite awhile before giving in. Plus I'm going t decrease the voltage to 3 volts I was at 4.5 volts so that may help also. I will keep you posted.
