	CLaNZeRS Homemade Ferrite Cutting machine part 1  Now shooting in HD, so please choose 720P and hit Full Screen! Quick bodge of the CNC machine too see if I could get it cutting ferrite rods for the PM-Orbo. Cheers CLaNZeR www.overunity.org.uk 2011年01月29日再生回数 1568
	4cm Micro slayer ferrite exciter  This is a Micro Slayer ferrite exciter measuring 4cm.It will light a fluorescent tube on a 1.5v AA battery.The former for the coil is an empty marker pen and the wire is a single layer of 40swg(0.122mm) or 36AWG.It requires a ferrite rod to be inserted into the tube for the circuit to work. 2011年03月12日再生回数 1977
	david showing ferrite+steel PMH  this is a ferrite core from a old TV and an old rail road spike...sanded smooth for good contact...10 wraps of any transformer wire and 1 spark from a 9.6v DC makita battery... a small 9v battery works as well 2010年05月20日再生回数 1416
	Joule Thief Made With A Ferrite Bead From An Old CFL Light Bulb  Here I make use of an old burnt out CFL light bulb for a Joule Thief light circuit. The ferrite bead/core from the CFL is at most 1/4 inch diameter and can fit in the core of my last circuit with a bit of room to spare. I used about 22 turns of fine (bi-filar=2 parallel wires) insulated wire. Comparing it to #30 gauge as shown in my last Joule Thief light circuit video, this wire seems about only half as wide (maby close to #40 gauge or so: seems slightly thicker than a human hair). If I used #30 gauge wire for this ferrite core then only 15 or so turns on it would be possible and may or may not have worked right.....it could of since the inductance would probalby be about the same as the recomended circuit. A Joule Thief circuit is basically like a "voltage step-up/increase" circuit. Voltage basically is the force that will be available to push the current around a circuit. 1.5V is not enough force or potential to push the current through a white LED light, so a Joule Thief increases that to about 3 to 6 V approximately, but can be more. I put a round ceramic magnet near the coil/transformer of the Joule Thief circuit, and the LED dimmed a bit. I guess the inductance of the coil went up leading to a higher reactance (ie. resistance) in the coil, which would diminish the available current. Some more notes for the value of R, the resistor in this circuit: 1K is the reccomended value (but could be a bit less). The circuit will work, produce some light, and diminishing ... 2010年11月15日再生回数 5316
	Ferrite core in Tesla Transformer  Submit your magnetic field of the Tesla transformer with ferrite core of medium of radio waves. When using the Tesla bifilar coil, the field is considerably stronger than in-line coil. successful search masatbg 2010年04月10日再生回数 24044
	TROS aircore ferrite  Copy of a video from youtube user: www.youtube.com user Mopozco gave me permission to post it on my channel. Please go to his channel for more on this video. Many thanks. 2010年10月29日再生回数 1142
	TROS -- "ferrite interrupter"  playing with simple tr.os. have noticed interesting behave of oscillation in wire -- when wire passing through the ferrite, on it's ends forming the difference of potential or rather difference in frequencies; when magnet applied to ferrite it blocks the oscillation in ferrite and ferrite can't interrupt oscillation in this part of wire, but does nor affect independent conductor inside the same ferrite since it affected by oscillation in wire; very funny... 2010年11月15日再生回数 3246

	Ferrite Heat Pump / Part 1  Hoping someone could suggest low cost and easy solution for cooling one ferrite leg becoming very hot due to either induction or magnetostriction when in ferroresonant mode, transforming the extracted heat to electricity would be also fantastic. Thank you in advance, Albert 2012年03月24日再生回数 206
	Benchtop ferrite air coil winding machine  This inexpensive bench top winding machine produces air coils for ferrite-cored inductors. The in-line insulation stripping unit and pneumatic wire cutting system allows the legs to be stripped much closer to the component body than would otherwise be possible. See www.coilwindingmachines.eu for more information. 2009年10月23日再生回数 10381
