Yes. I frequently find I overtax a components max. ratings (the smell of
burnt electronics is an acquired taste, like tobacco smoke and beer
grin)... I tend to pick up large quantities at auctions and surplus
outlets... replacing "sane design methods" with brute force and the
wholesale slaughter of un-counted components...
And, one should use caution with my labeling of components--I have boxes of
silicone diodes which are "similar" to 1n914's--and pounds of mis-valued
resistors/caps (the manufacturers just don't realize the value of a resistor
marked as one-ohm--when the actual value is one meg-ohm!!!)
"Whatever works!" sometimes becomes, "A list of what doesn't work!"
Quite often, the answer lies in "what I haven't tried..."
I don't expect all to be able to appreciate my "methods"... but, it breaks
the monotony of having to be so precise--which my field places upon me...
Warmest regards,
John

| Cecil is right. Also, the 100K implies 200V to get 2ma of LED current. The
| 1N914 won't hack that.
