Pulse width modulation shown on a the scope.
Posted by: tangnatalaga

Video duration: 286 seconds

This one example of controlling the duty cycle of a square wave. There several way of controlling the cuty cycle of a square wave such as mixing a sine wave wtih a triangular wave in which depending on the ac amplitude, result in a modulated square wave. The smaller the AC compared to the triangle wave the less the duty cycle of the resulting square wave. August 6, 2011 05:00 AM

This is a pretty good demo, showing what a MOSFET does, and the polarities needed. It also shows the "memory effect" (capacitance) of the gate - you apply the gate voltage momentarily, but the source-drain current remains constantly on or off, and the fan keeps going even after you remove your finger. I could figure out the circuit,? but it would be helpful if you included a schematic in the video somewhere. Good job!

@DancingSpiderman Very Good wow this is a learning experience to me. Anyways I am not so good at coils transformer etc. I remember a while back troubleshooting a portable generator after a hurricane. I could not get it to work. There seem to be a smaller winding that controls it to make it work. The main winding was not short or open,but somehow I did not know what to do with a smaller winding that seem to control it. An electrician whould probably know more? on inductance than me.

By: DancingSpiderman. on 09 Aug 11, 06:23:06
@tangnatalaga Correct. The current at the Gate of your N-ch FET is essentially Zero when current flows from the Drain to Source pins. The N-ch FET is activated by an electric field caused by a buildup of positive charge at the Gate , in this case, due to you bringing your finger very close to the Gate of the FET -- the "field effect" of your N-ch FET.? The electric field effect caused positive charge buildup , beyond the On-Through threshold of the FET; current flows from Drain to Source.

@DancingSpiderman The FET on the video does not? really care that the current is much smaller in fact million of times smaller. It responded to the voltage which is still the same voltage as the supply voltage but with such a small current. This is one reason why it can be damaged by static electricity which has virtually almost no current but has high voltage which is so much higher than a FET maximum allowable voltage.

@tangnatalaga haha sorry to mislead you, my friend. I do not have a vid on the subject. I am an electrical engineer,& so I remember my EE courses from college, explaining the bipolar transistor as a current-controlled current source, and the? field-effect transistor as a voltage-controlled current source -- amplifiers in more practical words. But I enjoy your explanation, because they are as you say. The line "Fun With Electronics, by DSM" just means I sometimes enjoy discussing the subject.

By: tangnatalaga. on 03 Aug 11, 05:42:24
@YourDadisHAWT You are right with the explanation except it is often misunderstood. Since energy can not be created (or destroyed), it is not really possible to "amplify" any given electrical quantity. People gets confused because they think? the actual electrical energy is getting bigger. It merely control the a bigger current that result in signal amplification. Signal is more of a mathematical expression in electronics.

By: tangnatalaga. on 03 Aug 11, 05:29:35
@YourDadisHAWT That? is where people gets confused. You understand the concept I assume. To amplify means to magnify right? You can't magnify energy and novice get a notion that is what is happening. This video is for novice intended to get their mind in the right track. later on they will understand the more elaborate characteristic of the transistor which I am still working on describing in the 2nd version of this video. Thanx for the comment.

Magnetic Pulse Welding (MPW) Process.mp4
Posted by: tangnatalaga

Video duration: 300 seconds

Magnetic Pulse Welding Uses very strong magnetic pulse created by a large surge of current usually in millions of watts that has been stored in arrays of large capacitors. It is very usefull for welding aluminum and copper pipes to dissimilar metals such as ac line. The idea is has been around for a while but it is just beginning to hit the market for industrial purposes.

Welding Aluminum using Mig wire n Butane Torch - November 19, 2009, 02:20 PM
Posted by: tangnatalaga

Video duration: 127 seconds

This is an economic way of welding and repairing thin aluminum. On thicker aluminum such as A/C line, you would use a bigger torch such as the propane torch. It is also a great way to practice brazing aluminum since a roll of mig wire can provide hours of practice while a magnesium rod will wear down very quickly.

By: tangnatalaga. on 14 Sep 11, 15:42:50
@KrazyJak90 So you are accusing me of being a quack? lol Why would I lie like that?. If that had been solder I would not be able to work with it. Also it would not stick to aluminum. from the heat of that flame being so thin. The mig wire is hard to melt but since it is so thin it does. This actually work although it is not easy to do. Since the aluminum? can is so thin and the surface area is small the flame actually melt it a bit so the mig wire would adhere. It is actually a form of weld.

tnx for the comment man. with the right equipment it is not that hard but a mig welder with argon gas is so expensive. those magnesium aloy rods are not? cheap either. mig wire n butane torch is probably the cheapest way to repair aluminum.
