You know when you get frustrated because you think you've done everything right and the circuit still doesn't work?

You check and double check and recheck....

But then after a month, you finally realize that you've just missed something stupid.

The difference between a 1.5K and a 15K resistor can make all the difference in the world sometimes....  Ugh. Please allow me to feel stupid.

I was checking a board layout to a design I drew myself a year ago.... everything was right. Then today I decide to check it against another schematic and found the discrepency, and realized that the "decimal point" was really just a smudge.... Ugh

I'm having to begin to think I'm getting better at debugging than building.
 I MUST remem to circle R values that say for instance 470.
 I can count at least three times that one's 'gotten me.
 I'm so good at finding yellow purple yellow, that I eagerly check with the DMM to see where the R of that part actually is....
 I had a 10k not. Read the same resistance as a wire. Took me a while to find that dum dog in the circuit !!! yes I found it....took me a while.
 That's why I say measure every resistor before placing it...too bad I didin't follow my own [actually someone turned me on to this] advice.
 Now I do. I measure every single fixed and pot R value before placing them. I thought I could trust the color code...didn't have nay problems for a long time...one bad R value can REALLy mess with your mind !!!

Thank goodness for women.  That always leaves us at least one thing we're stupider at. :wink:
