I know I am being a pain (lol) but when you ever feel like releasing your old Flux motor or/and generator documentation/notes (you know, the "fluxgate generator thingy") Please let me know!

Many thanks!
Kind regards

Steven,

I scanned the report and sent it over to Aaron. He will post it in this forum so everyone can download it. Its now in .pdf format. I scanned the file exactly as I have it. The font it was originally printed in is a little hard to read, and the pictures are pretty dark, being a copy of a copy. Some pages are not straight, as I have made no effort to clean it up.

When I spoke to John, he told me that getting the circuit to work is a real pain. The circuit controller must be able to produce a perfect 50%-50% flip-flop. The "cigar box" unit used Ni-Cad batteries, which is why they are labeled as 5 volts (4 x 1.25 volts each). The final working model used the 2N5885 transistor instead of the 2N3055H as listed. The control chip was the SG 3524 instead of the SG 3984 as listed. The system switched slowly, at no more that 20 CPS.

That's it. Have fun.

Peter
