Driving transistor bases without any current limiting resistors results in needlessly high base-emitter current, high enough to roast most transistors.

We know what the problem of our Charlatan is "incompetence" in electronics. About 100mA base current to drive a transistor for a 30mW bulb, LOL. @lenzrulz, your incompetence is striking! But we all know what your problem is.

Beware of lenzrulz. He is the most notorious liar, spammer and hypocrite on EveryCircuit. lenzrulz projects himself as victim, while he's creating resentments by his very own actions, and has been doing so for years. Be wary when he presents himself as tech-savvy individual - his incompetence in the field of electronics is striking. But don't take my word for it, see for yourself. Should you engage into debate with him, keep a hardcopy or screenshots of what was said - he may manipulate his comments. He continuously reposts his crappy spam under the pretext of "cleansing of defamatory comments", but has been observed doing so with crap which didn't even contain a single comment at all. As self-declared master of debates (rather, master of hot air) he doesn't hesitate to fabricate fake "evidence" to support his lies. He is not interested in Electronics, but in provocation.

That's what I did. Before you got in and played tech-savvy, completely misdimensioning the components I suggested him to him to add. You can't even tell a capacitor and a resistor apart without looking them up in internet first.

Bushmills

Your "solution" kills most transistors, and is therefore crap. Your dimensioning is off by a factor of 100 to 500. You tried to apply the suggestion which I've offered, but incompetent as you are, you completely messed it up.

lenzrulz

6 years ago

Actually my solution cannot kill transistors because they are well below the maximum current tolerances so you know what you can do with your opinion right? Now where is your link offering an alternative solution because all I’ve seen is your usual cowardly snide remarks but no assistance rendered to this user?

Bushmills

Congratulations, you just demonstrated your utter incompetence concerning electronics again. I suggest the following: measure base current, then compare against the max ratings of a common small signal transistor (BC547 is a rather common "universal" transistor). Then consider that what you're pumping into transistor base, is already the maximum COLLECTOR current. With such transistors is your base current about 800 times higher than needed for fully switching it open at maximum current. Your "maximum current tolerances" are for the transistor maximum, collector side. Not controlling side, base. But that's where you push a current, according with maximum device specs, into. Many transistors won't survive that amount of current into base - that among of current is the maximum of being switched on the transistor "power" side with many common "universal" transistors.

Bushmills

I suggest you read up on transistor beta to get an idea of how much current a proper base current should be.

Bushmills

As you're asking where my assistance to user is, please read the first comment, which says "Driving transistor bases without any current limiting resistors results in needlessly high base-emitter current, high enough to roast most transistors." Of course this needs a minimum of technical understanding, something which you sorely lack - which may be the reason why you can't recognize this simple hint as assistance.

lenzrulz

You've offered no assistance and tweaking the transistor isn't rocket science as you'll discover when you click on my link.

Bushmills

Obviously, lenzrulz hasn't mastered the art of reading yet. Or he hasn't yet figured out that reading doesn't just involve looking at words, but also needs to understand them. The point is not that tweaking isn't hard - the point is that your incompetence doesn't even allow you do recognize, that your loud mouthed "we know the solution - my solution can't kill transistor" will do just that, killing those, to transistors which were absolutely up to specs before you changed the circuit such that additional problems were introduced. Your "fixes" made it worse, not better - and you were utterly ignorant about it. Without spoon feeding, you'd not have known about the original problem nor about your introduced problems. But then you accuse me of offering no assistance (which I did) while you SABOTAGED the circuit (and called it "fixes"). What needs tweaking is your head, not other people's circuits.

Bushmills

"Driving transistor bases without any current limiting resistors results in needlessly high base-emitter current, high enough to roast most transistors." - I know that understanding this requires the level of technical understanding which you sorely lack. What is really disappointing is that you trumpet your flawed allegation of "no assistance" based on your limitation of understanding even simple technical concepts.

lenzrulz

6 years ago

You made a corrective statement but failed to back it up by stating how much resistance is required to protect the base of the transistor, no further information and no link to your corrective schematic, it would appear as though you didn’t know, as previously mentioned, it’s very disappointing that you offered no assistance whatsoever.

Bushmills

As this was targeted towards IgorResh, whom I consider quite capable to come up with proper values, and not towards lenzrulz, who is known as completely incompetent, determining proper values was of course left to IgorResh. That's what learning is about, being told what is wrong. That lenzrulz now whines that no values were given, so his need to be spoon fed wasn't satisfied, is the result of lenzrulz wanting to appear tech-savvy, but failed due to not having been given needed guidance. lenzrulz had also shown frequently enough that he's either unwilling or incapable to learn - which is why he can't get things right without being spoon fed. But of course he had to trumpet that "we know what the problem is" (in an attempt to count himself to those who know, but obviously, he doesn't). He's probably not even aware of what the other problem, introduced by him, was, and not even why it was a problem. That is why everybody needs to be warned about lenzrulz:

Spewing regurgitated “copy/paste” debunked nonsense isn’t very convincing nor detracts from the disappointing fact that you offered no assistance other than stating that there was a problem, no further information, no link to a corrective schematic, nothing...😬

lenzrulz

We could speculate all day long about your lack of assistance ranging from you simply didn’t know, perhaps an egotistical problem or an approval problem in that you didn’t want to upset the establishment if they disagreed with your base resistance values...

Bushmills

6 years ago

It's convincing because it describes you very accurately. Here and now the part of "Be wary when he presents himself as tech-savvy individual - his incompetence in the field of electronics is striking." can't get any more accurate. I actually don't need to do much for convincing anyone of the correctness of my pasted text - you're doing it already.

lenzrulz

Anyway, nothing alters the fact that you could’ve offered additional assistance but you didn’t!

Bushmills

Intelligent users don't need problems with their circuits fixed for them. Only lenzrulz needs spoon feeding (therefore expecting corrective schematics, accurate values, so that no own action is needed). But lenzrulz isn't an intelligent user. He's completely incompetent.

lenzrulz

6 years ago

Yep, when assistance is required, acknowledge the fact there is a problem but offer no real solution to the problem, just bury your head in the sand of blissful ignorance or better yet, post regurgitated “copy/paste” junk and hope they’ll go away...😂

Bushmills

6 years ago

Contrary to lenzrulz, I don't sabotage other users' circuits, but inform them of problems their circuits may have, in words they are likely to understand, even though lenzrulz doesn't, due to his incompetence. I don't fix their problems, I point out what's wrong. lenzrulz on the other hand adds to a problem in a circuit an additional problem, then calls his sabotage "assistance" and "fixed it" - as if he were capable to even see the problems. As much as lenzrulz hates to hear that, my approach of pointing out problems, explaining why the problem is a problem, and suggest a way to fix it, while leaving it up to the user to apply corrections himself is much more educative than lenzrulz introducing additional problems, handing it back and saying "here, I fixed it". Something which lenzrulz, depending on being spoonfed, will never understand, as his comments above clearly show.

The easy part is identifying a problem, the hard part is offering a solution. You’re dismal failure, as far as offering a solution is concerned, is well documented my friend, have a nice day...😎

Bushmills

6 years ago

That offering a solution is a hard part, you've demonstrated by adding another problem instead of coming up with a solution. A problem which was easy to identify too - but yet you failed. You didn't even manage to accomplish the - your words - easy part, while the hard part you "solved" by sabotage.

Bushmills

And yes, my solution is well documented. Including an explanation why the problem was actually a problem. And no drivel you're excreting can change that. Nor can any of your wishful thinking.
