Re: advice to a equalizer

Holy time slip, Bat man!

Any EQ will work, the most annoyance you'll run into with home stereo stuff is needing wires with RCA ends, the form factor, and requiring an AC power line (I'm assuming a mix of pedals otherwise) - but yeah, grab what's available and run it.

Re: Thread for random DIY-related questions

Here's a more conceptual, possibly philosophical question: how come different duty cycles of the same frequency sound different? I compared several different duty cycle ratios (in the format of %hi/%low: 50/50, 60/40, 70/30, etc.) of the same frequency and they all sound a little different to my ea...

You've got room for a piano? Absolute madman, very cool.

Re: Thread for random DIY-related questions

Now the solution from a practical standpoint seems obvious—get a new pot—but given that I've apparently burned through three of them already, I'd like to know if there's something fundamental (or subtle) that I'm missing before I keep throwing more parts at it. We'd need to factor in whatever you a...

Re: Thread for random DIY-related questions

Here's a refined drawing. It's nice to put a series resistor on an opamp for short circuit protection. 10-100 ohms should be fine.

Re: Thread for random DIY-related questions

Could you provide an example of this op-amp circuit? adjustableV.png You probably do not need either of the limit resistors (R5 & R6) though you could include a limit resistor from ground to insure that the lowest rotation of your pot just barely cuts out, or whatever effect you're after. Power...

Re: Thread for random DIY-related questions

If the power lead got grounded while the pot was only presenting a tiny bit of resistance it could easily overshoot the dissipation range of the pot. 9 volts across 10 ohms makes over 8 watts, for example. But the pot would only be seeing the full voltage if there was no load in between it and groun...
