i'm confured

3. ok, the transformer changes the voltage from 120V to whatever the transformer you select is set to, a bridge rectifier takes the negative swings and makes them positive. then all you need is a filter and... voila, you have DC.

oh but what if you get one that is from ac-dc 24V
do you still need them to make it have dc?

If it says ac-dc 24v transformer then you get 24v dc out. If building it yourself, then you need the awesome picto-hlep.

6. And we know how you like to make your own, so that's why pointed it out.

Transformers are easy. It is the wood widdling that is the hardest.

basically you need to wrap a bunch of wire around 2 things in close proximity and voila power.

Well what you wrap around it the hardest part. They have to be the right size or else the voltage out on the other end wont be correct. We are lucky that we use the roman alphabet because the size of the letters actually coorespond to the size in voltage when taking the voltage you want, modulo 26 (number of letters in our alphabet). Of course this little trick only works on the majuscule form of the letter.

So you have 120vac that you want to make into 24vdc.

120 % 26 = 16 = P
and then 24 % 26 = 24 = X

So you need to carve or widdle the letter P and the letter X into some ironwood (needs to be metallic or it wont work obviously). Ironwood is that sort of shiny heavy wood a lot of knick knacks are made out of. The bigger you make the letters, the more power you get out of it, so you can drive a bigger motor.

Once you get the "P" and "X" wrap half a spool of copper solid core wire around it. Make sure to use the whole half spool. This is what will actually shoot the AC electrons over to the DC side, and also what will catch them. If you are sloppy at this step the performance of the entire project will be comprimised.

Then you should hae 2 tightly wrapped sort of 2D objects. Put a piece of something nonconductive between them like styrofoam, and press them together hard. Wrap with something non-conductive to hold it like string, tape, glue that sort of thing, it doesnt matter at this point.

Now you have the transformer part. I will let h3rk explain the rectifier

7. The pen is mightier...the science is right there...

8. Ok here goes, it's been a while since I learned about these so bear with me.

Now that you have the transformer that jumps the electrons over so that they have a biased properly to X. Then you need to sort them out so they know which way to go. Think of a recitfier as a couple of subway turnstiles. When electrons come out of the top end of the X coil they go right through the turnstile. The rectifier lets top exiting electrons go through without paying the fee, kind of like VIPs. However the other 50% of the time, electrons come out of the bottom of the X coil, there's nothing we can do about it, they're AC electrons, thats what they do.

The easiest way to reject those bottom trons is with only one turnstile so that the bottom ones can't get through. The other way redirects the electrons so they both have to go in the same way. This idea was invented by some old baseball player, I think, because the idea requires putting all of the one-way turnstiles in a diamond formation. This makes more power.

Now obviously you're not going to put real live turnstiles in your transformer/rectifier, but you can make something called a diode to use instead. What you do is take a wire and bend it in a diamond formation.and solder the ends together. Then you take a sharp instrument (you can also have an electrician do this for you if you're worried) and cut a notch in each side of the wire. Be careful not to cut all of the way through, but it needs to be more than half way the notch should look more like a \| than a \/. 'make sure the straight up-and-down sied is always on the right.

This creates a gap the electrons have to jump through but they can only jump through one way. Its genious!! (Some call it a P-N junction, and throw heavy duty terms like 'potential hill' and 'forward bias' and 'reverse bias' around, but it's really not necessary.

Now connect the top of the X coil to the top of the diamond and the bottom to the bottom. no connect a capacitor across the left and right sides of the diamond. Often called a collector, it collects the electrons that sneak through the wrong way. then you connect a wire from the right to the positive terminal of the motor and the other wire goes from left to negative. Done. You have your own 120VAC - 24VDC power supply.

Also:
make sure that the rectifier is well insulated, you can put the diamond in a small box and fill it with anything like plastic or melted glass, just make sure the gap in the 4 notches is completely filled in, this helps guide the electrons through the gate.

Like I said I haven't done it in a long time, but I think this is how it goes.

would that work not to buy anything else?
and is there a range extender you can get to make it go... 300feet to a mile or something

is it ok if i buy one though? a little less complicated
