Hi msinfo,
I tried the original circuit you described but I'm only getting ~3v going to the LED when ON and 0.1V when OFF... Any hints?
Here is what I'm using:
- 12v source
- 12v LED
- R1 4.7-10K
- R2 4.7-10K
- R3 10-20K
- C1 1000uF 16V
- 555 Timer (http://www.thesourcecc.com/estore/Pr...roduct=2761723)
- D1 50V 1A 1N4001 (http://www.thesourcecc.com/estore/pr...roduct=2761101)

I think everything is connected right since I was able to use R3 to set the threshold (I tested with 12V and was getting ON/OFF and with 5V it was just OFF) and use R1 and R2 to adjust the frequency.

Thanks,
JZ

P.s. I'm no electronic expert, but I'm willing to learn
