Servo motors are special ones. Check this out http://www.epanorama.net/documents/motor/rcservos.html

NEED MORE DATA ;D

Unfortunately PS2 -> USB is not that simple. You shall need a USB 1 compilant microcontroller, impliment HID protocol, impliment PS2 protocol and interfase these protocols. It would be much easier to buy readymade converter. You can also search if a chip is available for this.

Put a microcontroller in between them ;D

Yep & next step would be to use DOS for ultimate speed ;D And about the system restore, it will store the files on your harddisk in a hidden folder named "System Volume Information" on each drive eating up space. It will copy exe & dll files into that folder whenever ou try to install something. Just check these links out -

backemf = VCC - (I * DC Resistance of the Coil)

I hazard a guess that you are not refering to servo motors used in model planes but are refering to tiny DC motors used to propel simple battery operated toys. These are the basic DC motors with a permanant magnet to generate stator field. To speed up such motor you can increase voltage accross it (i.e. increse the armature current).

What a wonderful proof :o
d/dx(sin2x) = d/dx(sin2x) * d/dx(2x)
= 2 * cos2x
remember the chain rule for derivative ??? http://www.math.hmc.edu/calculus/tutorials/chainrule/

Have you measured the voltage accross capacitors after connecting them in series?
The charge equation for the capacitor is -
Q = C*V
When you connect two capacitors of same value (100uF in your case) in series, resulting circuit will have half the capacitance (50uF). So the voltage across the circuit will be doubled to mentain the charge. Similarly voltage will halve if you connect two capacitors in parallel.
This won't happen if both of them are charged.
BTW what is the full form of ZPE? -
i meant to say "dedicated digital timer" time for mental checkup ;D

Weird Description ;D

;D WAKE UP DUDE ;D
Atleast visit the sites posted. The JDM programmer uses serial port only & though Ponyprog used Parallel port in an early revision, it is using serial port now & source code for linux is available. There are multitude of programmers out there which do the programming using serial port for PIC or AVR you can use any one of them as referance. They don't use the TxD & RxD lines anyway but directly modify hardware registers to generate necessary waveforms on other pins (like DTR). Anyway if you want to use a microcontroller go for an 8 pin PIC or AVR. This is a perfect application for such a microcontroller. -
just search google with "transverter design" ;-) http://w1.859.telia.com/~u85920178/conv/conv-00.htm

In windmill generators, constant speed gearboxes are used. They act like mechanical regulators for speed. If you can get hold of one of these, you can produce a clean signal with exact frequency. Insted of going in for multiple alternators, you should have one big alternator giving high voltage output which can be stepped down to whatever voltage you need. It would be hard to synchronise the alternators & run them in parallel. why would you need an inverter when you are getting AC directly.

Dear Kevin,
RMS = Root Mean Square
It is the root of the average of the sum of squares (sounds kool ;D)
see http://mathworld.wolfram.com/Root-Mean-Square.html if u like equations.
& btw derivative of sin2x is 2cos2x -
Here is a large dose of theory ;D http://www-ccrma.stanford.edu/~jos/filters/

I found a good discussion here -
http://www.epanorama.net/circuits/rspower.html -
Check out the pony prog. www.lancos.com/prog.html or JDM programmer http://www.jdm.homepage.dk/newpic.htm or any other serial programmer capable of programming Serial EEPROM. Many of them post the source code so you can go through it & do whatever u want. :)

You can use RS485 if the distance is large.
-
You can not get delay in terms of 10mins from a 555. Well not without very large capacitor & similar tolerance. Better use a dedicated timer IC for long delays

Why can't you folks draw a schematic diagram like rest of us? ??? Or perhaps the mysterious ways of over unity clan are visible to those with inner vision?

not found anyboby to hat with yet ;D
Need a P-Channel FET subs.

I figured that the JFET only shorts out MBus & Fbus Tx pins. I daresay you could replace it with 74HCT4066 quad analog switch or if you can find it (or sample it ;D) SN74AUC1G66 (Single Bilateral Analog Switch) from TI.
