Hi Guys,
Copper strips are in, paper is in, core and bobbin samples are in, kapton tape
is in.
I am going to ty to fit 5 turns of 2X20 mil 0.75" wide copper strip and 10 mil
nomex onto a PQ3535
ferrite core set and gap it 0.008" which should give me about 20uH of
inductance for the flyback
transformer. This may sound like I am trying the impress you guys but it is
just basic switching
power supply design work. I was listening to my favorite song "She blinded me
with science" full
blast on the way to work yesterday so I thought I should jazz you guys up with
a little BS.
On the money matters, I spent $100 on the TO-247 schottky diodes, $60 on the
TO-247 FETs, $120
on the transformer materials, $50 on the IC's, $36 on a 250Ampere Perko
1-2-Both switch, and
bunch of more money on other components. (Not counting the capital equipment
for testing)
My wife thinks I am wasting money and energy on something that nobody really
wants. She might be right but we are way past the point of no return. We will
either fly or crash.
This box will be humming and that is all there is to it.
I expect to start uploading some photographs of the breadboard and sending you
the link
to my webside by the end of next week.
By the way, one of our sailors Jim Lynch is evidently a EE and he gave me some
inputs
for a reasonable cost PCB manufacturer gEDA that we might use rather than
PCB123
which is the current plans.
Unfortunately the workload at where I work is also ramping up which is taxing
my energy.
If I could have only half the energy I had when I didn't know anything.....
All the best.
Ahmet
