Electronics engineers anyone???

Im trying to transfer power without using wires.....anyone know much about transformers???would be a great help...can explain what i have at hand....any help appreciated.....cheers........

Me. Well, by trade anyway. I kinda let others do the hard work these days while I spend my time on here.

Power without cables eh? Be thoust talking isolation transformers per chance? Inductive power transfer?

Although, to be pedantic, transformers aren't technicaly electronic devices, so the question should be put out to electrical engineers as well I guess.

I was thinking of IPT but kinda works out to the same thing as transformers as ill need a step up one in any case....ur right i shud have addressed it to the electrical engineers as well......hopefully theyll have a look as well....

Ahhh - I'd defo broaden it out to the electrical geeks here then. Phased transformers scare me. They can hurt. And burn.

i'm a 4th year student in electronics and computer enginnering so will help where i can. What sorta power you looking at???

can be anything from the IPA to waves (micro) but i doubt you have that sort of resource.....unless you do that would be awsome :Punk:

I used to work for a transformer manufacturer, i.e. winding, assembling and testing of them. What are you trying to do??

Woohoo! The spirit of Tesla lives!

Actually.... This works..

I supported some guys in one of the 'incubators' (The Icehouse) at a trade show and one of the business's there actually has a working model! I was impressed to say the least.

When you think about it... When we can efficiently transfer electicity wirelessly it solves a hell of a lot of problems and potentially makes electic vehicles more practical.

I have the guys card some place. PM me monday and I will see if I can find it.

Nikolai Tesla actually developed and proved this concept in the last decade of the 19th, and first 2 decades of the 20th century. Nobody wanted to buy electricity off him though, because they thought he was a nut.

Jim2 from what I understand there was lots of controvisy (sp) over it all, Good old Edison was using Tesla's AC system to electricute dogs and thus prove how dangerous the whole system was.

My understand is before he died/dissapeared he had a setup to transfer power from LA to Paris via wireless but I think he ran out of money etc or something like that. Would have been very cool if we had that today.

Edison's power grid was DC. He had a vested interest in a. not paying Tesla the millions he owed him, and b. discrediting AC power transmission (not just wireless transmission). Who's the idiot now, eh Edison?

Exactly, sort of funny though how everyone has heard of Edison but Tesla has sort of been forgotten about. Of the two Tesla was certainly the brighter one but I think Edison was better at the PR stuff.

Nicola Tesla tried this on a large scale in the '20s or '30s,worked too,but I think people didn't like their hair standing on end all day.

Can't do it today -the hippies think EMFs make them get cancer and commit suey side.

Which I think would be a good thing.

heres what i need ........im trying to operate a wrist like device having three claws so that they can open and close as and when needed...something like the toy gaming machines with finger shaped machines that swoop down and pick up the toy(if you can get a hold of it)...in any case i am not trying to achieve this......now these three claws were attached to a circular disc,120 degrees apart.This disc is meant to rotate in either direction and the claws are meant to open and grip a ball as and when needed...it would be better to show it in person as itll be a lot simpler...very difficult to visualise..ill try and put up the prototype drawing...can i just put it as an attachment??

Edison was a crook, he had scores of wage slaves thinking up inventions for which he took the credit.

Tesla had an electrical unit named after him. Edison only got a screw .

U at auckland uni as well???this is a small part of my 4th year proj....

nope i am an MIT boy. But yeh i had to pull out of my project last year to to incifficient time dumb supervisor etc etc etc. But am doing it again this semester. DOn't know on whta yet though.
How big is this project?? What sort of power are the servo's pulling??

i suck at the DC motor specs but we have a scaled down version with the resorces we have at uni...using 2 motors that give abt 1Nm torque i think....we had to scale he projec down based on this as well....wanna drive this using a 24V car battery......
