New comer needs any and all help

[jhsmith87]

hi every one, first off this is my first post here. i am new to this topic, but very interested. i am trying to learn about it as much as possible, at a hands on type approach. so after i seen it, i really wanted to build a bedini motor. the only problem is the circuit.
from what i understand i need a very fast switching transistor. i am very far from any where that sells electronics, so i use scrap parts, (witch i have a lot of) i got a lot from a few older computers (2005), and other things.
any way i was looking up the numbers on these transistors, and found some that is called a schottky rectifier if i am correct, marked wc2401. i have read that it is fast switching. but the name rectifier is throwing me off.
so can some one please explain to me more about this thing, and if i could use it in the bedini motor.
also in the computer i seen some transistor marked 45N03L, stps3045cw CC1k2 u MRC 415. and was wondering what they was used for. and how to wire them into a circuit to get that fast switching action i need for the bedini.
Any info you could give me would be helpful.

P.S. i forgot i have a reed switch, but it kinda confuses me. as it has 4 pins, 3 on one side and 1 on the other side. i'd rather not use the reed switch on the bedini but would still like to know how to hook it up, since it has 4 pins, i know basically how it works just not how to hook it up.
sorry for the long post.
thanks alot for any help. 

here is some pics of the things i am talking about tried to get it clear enough for you to see the numbers on each one.

Well, hello and good luck.

First off, you do need a transistor, not a rectifier/diode. The power schottky dual diode STPS3045 is a neat unit, but it's not the kind of switching component like a transistor and/or reed switch that you need for your project. There are other things that you can use them for, though.

The problem with using components from PC power supplies or TV sets is that they often have manufacturer's markings that are impossible to trace and decode. I couldn't find anything for the Bo or B0 407 thing.

The "reed switch" that you are describing with 4 terminals sounds like a reed relay to me. Again, not exactly what you are looking for for most Bedini-type motors. Your part probably has a coil (two terminals) which will read some small ohms value on the multimeter, and contacts (two or three terminals, one might be shared with a coil terminal) that will be normally open or normally closed, like a SPDT switch. In other words, there is a reed switch in there but it's wrapped with its own actuating coil.

If you can find old TV chassis, you might be able to find the right kind of transistor in one of them. I pulled out a 2SD870 from one the other day, it is suitable for your purposes, 1500V 5 A npn, used as horizontal deflection amplifier in the TV set. Be careful of capacitors that could retain a charge, when you are messing around in old TV sets.

The PC power supplies might have mosfets in them that might be suitable, but generally you will need a transistor with higher peak voltage ratings than the ones you'll find in the PC supplies.

EDIT: Ah, OK I found the 45N03L data sheet. It is a 30 volt, logic level N-channel mosfet. You "might" be able to use this but the spikes from your Bedini circuit will probably kill it. Of course... you will need one with all 3 pins !

Actually that mosfet looks like it would be very useful for me, for a small Royer oscillator flyback driver circuit. I'll have to see if I can find any of them in my old junk box.

thanks very much for the info. i understand now what you mean about the parts i have. yes i have an old tv i just havent taken it apart yet.
yes the reed switch i spoke of is a reed relay. the packaging says the two pins are one for coil input and one for coil out put, the other 2 are for the switch its self, i have used the switch before just using 2 pins to see how it worked.
i also have 2 transistors that i got from radio shack a long time ago. they are one pnp NTE153 and one NPN NTE152. could either of those work for my project?
aslo as i said before i am at very very best a novice in anything like this, i am not so much interested right now in building this project to try and achieve overunity as much as i am just trying to make the rotor spin nicely. once i have mastered that i can then if i decide to try to go further.

i have no idea how to make this circuit or the coil. i mean i know how to wrap a coil and that it must be a coil with iron or something in the center, but no idea what is the minimum amount of turns i must have, or gauge.
i understand how the thing works, the coil shuts off at a certain point then is turned back on, and so on, just no clue how to do this.
can you help me? explain to me how to make this circuit and a proper coil, dont have to be a coil that is going to give me 2000rpm ha, just a simple low speed continuous spin would get me started.

i also read somewhere about using ir emitter and detector to turn on and off the coil? also a toroid coil instead of a regular coil with iron inside? any insite on that?

if anything could i just get a simplified version of the circuit lay out. maybe with a bit of "idiot proofing" ha. like instead of symbols and letters just say resistor, or what ever. i know overunity info and plans are being "suppressed" i guess. but to be clear thats not what i am looking for just the motor building plans.
thanks for the reply and i really hope i can get you or some one to help me with this, as i find it super interesting but very frustrating when i spend hours on it, and it never works.

you can build a bedini circuit with parts scavenged from a pc power supply no problem... i have made several that very same way. you can get the transistor needed and the diode(s) and you can probably even scavenge a resistor that will be reasonably close to your needs... you probably won't find a neon bulb in a modern pc ps though.

the transistor was a 2sc2625. the diodes were a 1n5404 on the output and a 1n4001 on the input. your resistor value will vary depending on your coil.

as far as minimum winds for the coil... i wouldn't go that direction until you have a working motor/energizer. i'd recommend at least several hundred turns... once you have built a working one and understand it a little better you'll have a better chance at getting a 'minimal' one working.

good luck!

Well thank u very much that brings my hopes up a lot. But I am still far from close to understanding how to make one.
I still would like to know if some one could help me in building one. As I said I am very ignorant right now on building components, although I understand fairly well how they work.
Ive seen diagrams on how to do it but none I could really understand. Also the npn 152 transistor I already have I hope will work in order to keep me from sorting through my scrap pile for one..

So my main question still stands can anyone give me a for lack of better words idiot proof how to or step by step.

I did just make my coil.(the easy part) 2 strands of 26g wire twisted together to give me 4 leads, wrapped around a plastic spool about 400 to 600 turns. With iron filling the inside of the spool. And thats it as far as ive gotten or can get.

Can anyone help with a step by step
