--- Quote from: Simon on February 24, 2015, 08:53:47 pm ---Well i'm sorry but unless you do things right they won't work! why the hell are you trying something as complicated as a variable frequency drive when you don't have micro-controller specific programming skills and you don't even know how a diode works even after reading about it. I'm sorry but we can't make you learn and there is no secret. Unless your going to do things properly and in some order then I'm sorry but there is nothing we can do.

you claim to know all about programming but don't understand the concept of PWM which is at the basis of controlling real world devices like motors with a digital microcontroller, so I suggest you stop thinking you can do anything in java and learn to program properly in C like everyone else does at this level of development and learn basic circuitry techniques. You seem to be blissfully unware of just how much you don't know (not that I'm an expert either) and yet there is no way to explain anything to you. For gods sake get the simplest beginner book and read it!

Sorry, but you don't seem to understand how programming languages work... (check it out: http://www.espruino.com/Reference#software) also, I was asking about the physical internals of how diodes work (not how they're applied and what the macro effects)...

Also, you either do not know any good part numbers for cheap inductors, or are being deliberately dense given I've specifically asked you like 4 times now...

I was under the impression PWM was duty cycle and htz as explained by sparkfun

https://learn.sparkfun.com/tutorials/pulse-width-modulation

if it's not, could you explain what it is?  Otherwise, could you stop commenting on my post?

Inductors are usually very specific to the purpose of the circuit. Radio hobbyists often just wind their own. If you want a cheap inductor just take a piece of wire and wind it around something in a spiral. You can find instructions in this book.

Take you pick: http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.Xinductor.TRS0&_nkw=inductor&_sacat=0

Or as suggested just grab a length of wire and wind one, jeez let me guess you learnt all about programming on a PC and now that you have found you can program microcontrollers with the same language you think you can take on the world of electronics  :-DD

Not sure what you have against Javascript, but it might be a good idea to look into, probably improve your productivity actually...

Btw, there's this sale on ebay that claims a photoresistor is an inductor... I already have photoresistors, but I wasn't aware they were also inductors (not sure what part is suppose to be a coil, or in the other sale I posted that looks a lot like a resistor too...)

Btw, does it make sense that you as a moderator can be so flagrantly rude to someone on a forum but I'd bet the moment someone is even slightly rude to you, they get banned or whatever it is you do to them?
