Stanley Meyer replication with low input power

[Duranza]

Oh WoW! that looks great... Does it include the BUZ350 with it? or the replacement?

[djctek]

It uses a Fairchild Semiconductor 200V 28A N channel mosfet part #FQP32N20C. The BUZ350 is an obsolete part that has not been in production for years and are nearly impossible to find. This is a beefier version compatible mosfet. the BUZ350 is rated for 20A.

Glad you guys like the design!

Virtually any n channel mosfet will do the job so long as can handle a drain current of a couple of amps, this assumes you do not want to draw more than a couple of amps of course.

Ravi's replication draws 0.5 amps, a mosfet with a drain current capability of 2 amps would be sufficient.

But what you really have to take into account is the voltage the mosfet can handle because of the back emf from the coils, certainly make sure your mosfet can handle more than 100 volts.

This is the mosfet I use and despite it's Vdss being only 60 volts, it works quite nicely in my setup...

Well said RunningBare, I think a lot of people over stress on the need for the BUZ350, Probably because the name sticks in your head and is easy to remember, There is nothing special about it compared to any other 200v N channel mosfet.

Hi all.

i stumbled across this site a few days ago via youtube, and i must say, this is some pretty amazing stuff. i'd like to build a replication, but im not sure about a few things.

are all the 555 timer chips interchangeable, or is the NE555 imperative to use?
is the alternator in the d14 setup used to power the rig? What is its purpose? (i have a small engine i may want to play with)
is the input power controlled or just let the rig pull what it needs? i don't want to overpower while conditioning tubes.

i've built a number of pc's, but nothing like this. any help is most appreciated.
