So I was typing up the next installment of my SP blog a couple nights ago and ran into a little problem. The blog post was going to be all about my gunshot detection interface (back-story, theory, my implimentation, schematics... the works), but as I was reviewing my circuit and creating the schematic, I realized that my OpAmp circuit was a little odd. After doing some snooping I found that an extra resistor had been either added or misplaced to the circuit. This can cause some very bad times depending on the circumstances. I spent a couple hours in lab only to find my circuit was oscillating (this was not at all intended). I've come the conclusion that I've probably destroyed this particular OpAmp (not a big deal, they cost only about $0.40).
Anyways, I know I said we have quite a bit of ground to cover, but for the mean time I need to fix and verify this circuit before I can tell you how it works.
Thanks for being patient,
I'll be in touch.
