Tesla's Charging Circuit and it's Application to Pulse Motors

[Farmhand]

Yes a noble pursuit to out the scammers, I like to pick the scammer then learn what I need to so I can demonstrate their "so called OU effects" myself. I think because I am not a electrical engineer and never formally trained in electronics if I can show for example, the speed up effect, and repeat it with different setups and transformers then I think that shows it is nothing special or OU and not is result of what Thane says or thinks, it is explained by known physics. I can pick the "full of it" OU claimants as well (basically look for an OU claim and you've found another one) . It goes to show that  the gullible people don't do the tests the guru's claim certain results from. The hover magnet of UFO's was a doozy, he claimed there was a current and magnetic field reversal when the coil was pulsed which caused the magnet to hover. I knew it was rubbish I argued with him he got nasty, so I waited for a few months and many more were sucked in because they thought he had won the argument and was correct. When the time was right I showed the magnet hover with smooth DC and so his theory was completely crushed, he had no choice but to eat crow and admit he was mistaken. All the gullible who allow him to fill their head with rubbish ought to be able to see it by now.

Many people ought to be charged with fraud, But the hard core free energy zealots will see that as an indication of suppression not of criminals being punished.

I challenge anyone to show OU, meaning exactly more energy out of a system than the system contains or more energy out of a system than goes in if no battery is used. We won't see that because it's impossible, any extra energy out of a system compared to what "we " put in is a different matter and the extra energy must come from somewhere. And as soon as the source of the extra energy is identified and quantified the result would be exactly the same as the energy collected in other ways such as wind or solar energy.

Quite frankly I'm tired of the micro power devices and the oscillations of minute amounts of energy, also the anomalous measurements are tiresome, the fakers doing Kapanadze fakes. And the people who just link stuff and cry OU all the time bemuse me.

Tinsel I'm ordering the Arduino Eleven you suggested as a good board http://www.freetronics.com/collections/arduino/products/eleven#.UbBap_nPVqA
And I was wondering if you though it a good idea to get the 16 x 2 LCD Shield for Arduino. http://www.freetronics.com/collections/shields/products/lcd-keypad-shield#.UbBjMPnPVqA

I kinda like the idea of the relay shield as well maybe for motor circuit input power on/off switching or other control switches, battery swapping maybe, things like that. I'll check that out and buy it later maybe.

Couldn't resist, so I got he LCD shield as well. Thanks for the tip on the board it looks very good for what I want to play around with.

I was wondering if someone could tell me if I would really need a pull up resistor with this hall sensor circuit, if I modify the existing optical sensor circuit design and use a CMOS inverter chip with the hall sensor so I get both non inverted and inverted outputs, would the output (of the Hall sensor) not just go low when the magnetic field exceeds the threshold and then go high when the field is not exceeding the threshold ? Why the need for the pull up resistor ? The data sheet says I need a suitable pull up resistor.

With suitable output pull up, they can be used with bipolar or CMOS logic circuits.

Also says this.

OPERATION
The output of these devices (pin 3) switches low when the magnetic field
at the Hall sensor exceeds the operate point threshold (BOP). At this point, the
output voltage is VOUT(SAT). When the magnetic field is reduced to below the
release point threshold (BRP), the device output goes high.

Oh MileHigh, I've had the CMOS cookbook for some time now.  I occasionally recommend it myself.

I've made some CMOS logic chip oscillators that can reach stable frequencies of over 5 mHz with just a cheap CD4001, the better inverting chips can do better, CD 4049 I think.
It's all layed out in the cookbook, it's an awesome resource, SeaMonkey recommended it to me a year or so ago.

The Allegro sensor that you have chosen doesn't really have an "output", unless you provide it with an "input". It is an open-collector-output device. You treat its Pin 3-Ground output like the Collector-Emitter portion of a NPN bipolar transistor that can sink 25 mA. So you just treat it like a normal bipolar transistor in your circuit, with a suitable pullup chosen to keep the current below 25 mA when the transistor turns ON from the magnet passage. The value of the pullup will depend on the voltage at the positive rail and the downstream device you are switching.

In other words you can't get a logic "high" signal value out of it unless you provide it with a "high" voltage value to switch.

(ETA This makes it really easy to interface with microprocessor boards like Arduino. The same sensor circuit can be used with photodiodes, phototransistors, photoresistors or just about any other thing that acts like a switch when stimulated.)

Allegro also makes 2-wire Hall sensors that act just like a reed switch in a circuit (except without all the problems with reeds).

So in your schematic above, you need a pullup resistor between the collector of the Hall device and the +5v supply. Then when the Hall senses an event and turns on, the voltage at the input gate of the inverter chip will go from Hi to Lo. The value of the resistor will be >= to the supply voltage divided by the max current sink ability of the Hall sensor, which is 25mA, so a 220R should do the trick, but you should go as high as possible here, consistent with triggering the inverter, to limit current thru the sensor to the lowest value that gives consistent triggering.
I think. You should also place a 0.1uF 50V ceramic cap right at the Hall chip across the V+ and Ground pins, and the same for the inverter chip at its supply and ground pins.

(ETA: the way you've depicted the Hall sensor in your schematic makes it look "almost" like a bipolar transistor with its Base connected to the positive supply. This might be a little misleading, since it implies that there might be some Base-Emitter current happening like in a normal NPN transistor... but in the Hall chip there isn't. It's just a switch, between the collector side and the emitter side, so in your present circuit it is just going to open and close a connection to ground, and the inverter chip will just sit there going... huh?)

ETA2: A 7404-type chip might be easier to use, too. At least there are only two connections per gate that you have to make.
