Sorry Tomw
But I don't think enforced ignorance is the answer.
Not allowing or discouraging people from asking questions, or banning or censoring the answers is contrary to the life education of an individual.
Finding the balance between what is safe and what is not, is best left to the individual, benevolent dictatorship is no better than dictatorship by any other name.
The freedom to test ones skills or satisfy ones curiosity is instrumental to learning and living an interesting and fulfilling life in general.
There will be instances where this may lead to a sticky end, but that is outweighed buy the gains of freedom of choice.
We know that driving a car is dangerous, having trucks on the same roads is even more dangerous, but we accept the risks.... why?
This applies to nearly everything, and with 60% of us obese or overweight, there is serious danger here, but we can still eat what we want. We shouldn't be allowed to. It will lead to heart attack or some other malaise, but we weigh the risks and make the decisions ourselves......far far more important than burning down the house....
I understand your viewpoint on this, but I feel that freedom to choose is worth any price, and Millions of lives have been and will be lost to maintain this creedo.
please let us choose, and be happy about it.
Sorry Tomw, just my thoughts...........oztules
ps. If he picks the wrong ic, it just wont work...it's at low potential. If he undersizes the fet, it'll just fail like the one before it...if he buggers it all up, he'll be no worse off for trying....he can still throw it away,.................. or just maybe, he knows what he is doing ( i think this is the case here), but just wants to know which pwm chip it is.....I've no doubt, once he has a pulse width going, he will bang in a fet of his choice and away he goes....It failed for some reason, and he will have to ascertain what that was before committing to full power.
I don't see the big issue here.......
