hi what,
I have 1w zenor's will those work?
If your zener diodes are 6V8 at 1 Watt, this would suggest that as W=V * I
and transposing I=W/V,,, I= 1/6.8 = 147mAmp.
[Calc your R1 to give the LED the max brightness, without exceeding its rating]
Is that really going to solve my issue?
If I didn't think so, I wouldn't have posted it!
It would take you all of 10 minutes bench time to give it a try.
So far I have been unable too using my zenor diodes.
What zeners and how were they connected?
