Careful, there might be a farting dragon down there.

We want to see the slutty sheep pic!

Ooooooh! Love the machine-turned finish. Pretty nice inside too. ;)

(y) MP38 No need to match them or anything. It's just a BMP.

I think your talents may not be fully appreciated here. Have you checked out the More Jokes thread in the Open Discussion forum? This was directed at Stickman, but I think it applies to Feral as well. 😁

All you need to make a resonant circuit is an inductor and a capacitor. At resonance, the voltage and current are in phase. If we can observe the phase difference, on a scope for instance, we can very precisely detect the resonant frequency. The phase angle is zero because the phase shift in...

I'm not gonna claim that I read all of the post in this thread, so please forgive me if I cover some old ground. The principle factors in inductor performance are: Inductance - inductance can vary with flux density Copper loss - aka DC resistance. At very high freq (above audio) we also have...

Alright, so I am experimenting with making the DEMHI/HALI switch a 3-position switch. Seems like a no-brainer. The 3rd position adds more bottom-end than the DEMHI setting. The jury is still out on this one.

I ran sims and tried it on the bench with a sig gen. I was able to obtain an octave-up effect. Then I tried it with a guitar. Here's what I found. With R14 disconnected, the octave up effect works best with BEFORE set around 7, AFTER set to 0. Adjust BEFORE and/or guitar volume for the best...

Also known as the PedalPCB Carcass Fuzz. This beast is everything people say it is. Quite the range of tones. Something for everybody, I suppose. I built it to stock specs, except I used 2N2222s for Q4 & Q5. Believe it or not, there's nothing that I want to change. As described in the...

With Mouser, you're guaranteed a legit part. I bought some on AliExpress and much to my surprise, they work great. 10 for about 3 bucks. Just to clarify, this is how I test 'em. Connect DMM across R2. Plus lead to +9V and minus lead to pin 4.

Those H11F1 numbers are so far off that it can't be a real H11F1. Might as well leave it out since the effect of the H11F1 is subtle when it's working right. $4 or $5 for a real LM308H sounds too good to be true. As a point of reference, I bought a large quantity of real LM308H last year and...

Did you run any tests to verify that the LM308Hs are legit? I seriously doubt that JAMECO did. There are no factory authorized sources for out-of-productions parts, which means there is no traceability. No paper trail from you back to the manufacturer. They are a popular item to counterfeit...

LM308 test Build this circuit on a breadboard: LM308 pin 2 to pin 6. pin 3 to gnd via 100K. Pin 3 to +9V via 100K. Pin 4 to GND. Pin 7 thru a DMM set to measure μA to +9V. Apply power and measure current into pin 7. Typical current draw is 300μA. I have measured as low at 250μA and as high as...

Oh, come on Steve, it wasn't THAT funny. :rolleyes:
