Errr, make that that "silicon diodes", I keep gettin' 'em confused with the
girls! grin

resistor

| "Whatever works!" sometimes becomes, "A list of what doesn't work!"

|
| Quite often, the answer lies in "what I haven't tried..."

breaks

||
|| Cecil is right. Also, the 100K implies 200V to get 2ma of LED current.
The
