As I recall, Wilf came up with a charge pump circuit a while back. Take
a look in the Rigter Archive at the Beam Heretics site:

when kodak first introduced these cameras there was a lot of write up about
the motors revolutionary size/efficiency... it is this ancient history???

11108 Tue, 29 Feb 2000 13:01:34 -0800 [alt-beam] BEAMAnt circuit "BEAM List" "Phillip A. Ryals" ok, I followed the suggestions of some people on the list to go with the
BEAMAnt circuit. It's confusing me though...

Remember the thread about a photovore that can turn on both motors at once?
I got the impression from some of the posts that the BEAMAnt cicuit does
that. I've put it together though, and it runs one motor at a time. Is
this right?

I'd like to find a fairly simple photovore circuit that uses the 240 or 14
instead of individual transistors, mainly to make building it easier.

I would appreciate any help.
