Solid State Orbo System

MAG, here is the pwm circuit i use, the switch + 3 caps at the bottom can be replaced by a single cap which can be changed depending on what "range" you want.

p.s re:- casting cores, you could always throw in some iron filings etc into the magnetite to increase the permiability, also would be possible to cast a toroid ( albeit a square toroid if you know what i mean ) 1 leg at a time, and wind it 1 leg at a time, joining them up as you go....this would make winding SO much easier than winding a complete toroid all at once.

Thanks Rave
I didnt think of it before, the diode I am using in my 556 circuit is not a fast switching. I found this by searching the 1n4148.
I like the idea of making my own cores. I will look into it.

Did ya ever have one of those things, something you have been working on, and ya seem to be getting good results, but then you find a discrepancy. Something that has not been noticed the whole time. Well I found such.
I was taking power board caps out to try others because one was causing the circuit to act funny when I touched or moved it. So I took it out and the circuit acted funny. Put it back in, was ok. Tried another cap, same thing.
The only thing between the battery and the cap was the on/off switch. I took out the switch and Bam  My output went up to 13v on the output with the light bulb gleaming.
I did a vid and went to load it to yt and while I was waiting for the vid to load I had bit back space and the page changed, when I went back it as a new upload page. So I uploaded it again, filled it in and when I went to see my list of vids, both were up there, so I deleted the previous one, and the new one ended up rejected due to duplicate vid. Soooo   Im making another one next. It will be up in a few. Ill post when its up.  =]

Added some biasing magnets and a different cap on the pickup and I beat the 13v of the last vid above.  16.7v on the 12v light bulb. I am going to have to put them in parallel to strengthen the load, and to conserve these nifty lil bulbs.
