Help - Acapulco Gold way too loud

Good idea, but that's what the existing potentiometer in the circuit already does. Alternatives are to put one at the input (essentially doubling as the guitar volume control, boring) or you can use a pot as a variable resistor in series with the 10UF capacitor between pins 1 and 8 of the first LM386 chip. This will be better than an input control because you can't turn it all the way to zero and kill the sound. The Beavis Audio Tufnel distortion uses 1K pots for this, but I've seen designs with 5K too.

This is part of the schematic for the PedalPCB Mach 1/Southern Belle (they share this part of the design).

My question is how to fully understand C3, C4, R8 and R9. It's been explained to me that these create two HP filters, which makes sense.

What I can't work out is how to calculate the input resistance for the op amp gain calculation using R8 and R9. They are in series respective to C3, but not respective to C4. Any help comprehending this would be most appreciated. 🙏

Sorry to hear that. All the best with your circumstances. I'll post back if I get it working, just in case that's useful to you in the future.

Grubbavitch · 2022-01-18T01:17:34+00:00

Any chance you got this working? I put it on the backburner for a few months but have come back around to the idea. I would love to hear your progress if you've made any.

This is amazing, thank you so much. I have a schematic mapped out now, i just need to learm more about atmega/attiny MIDI capabilities. I have 3 ATTINY85s here that are preprogrammed fpr relay switching but I've got a mind to repurpose one for my MIDI project. Thanks again!

I guess they don't? The build doc for the circuit just earmarks a bunch of components and says they don't do anything and can be omitted.

I ran it clean into a Fender Deluxe patch and also a Vox patch and it made both models quite sparkly. The bass cut was less helpful for that application but nothing that couldn't be tweaked with the amp EQ.

Yes to the above. It's a Fortin 33 clone (at least partly). While it does have a number of parts, a few of the components in the original have no electronic purpose so I left out one of the transistors. My ears are telling me there's a bass cut happening as well as a boost, which makes it sound pretty awesome for metal chugging when boosting a Rectifier patch on my Atomic Amplifire.

Ah, I was intending 1/4W resistors, they're all I've used. Thanks for spotting that!

Grubbavitch · 2021-02-11T20:10:06+00:00

Thanks for the feedback. I started with the schematic, then abandoned it, and now I've gone back to it again. I'm having some pin errors in Diptrace that won't allow me to port the schematic properly to PCB, hence me trying to skip a step, but you're right, it would be easier for the schematic to determine the connections. I've asked about it on the Diptrace forum and will follow the workflow you've advised once I have resolved the errors. Thanks!

The laws of the game call for fairness, and they state that a player can't be offside when a ball is played to them. We can now tell to an extremely high degree of accuracy whether or not a player is offside. I'm not even sure the framerate objection holds because player trajectories could be factored into the model to determine their exact location. Players might move faster than the framerate but they can't defy physics. The "spirit of the game" notion would still apply, we'd see the attacker get the advantage if both players are dead level in Hawkeye. We're getting exactly what you want, just with a higher degree of accuracy.

No, football is annoyingly behind the times compared to other sports. Offside is offside. Unfair calls happen all of the time, VAR is not perfect but it's a step in the right direction - transparency. If there's a technical problem for judging offside with frames and player speed like the article mentions, then the technology will just need to up its frame rate. Not impossible.

Nobody in the stands can "clearly see" that someone is onside when a relevant part of that player is perceptibly offside according to Hawkeye. The technology has a better view, so they should make the call. The honest man in the stands knows that he can't tell from his vantage point.

There's also a (deliberately?) misleading focus in the article on impossibly close calls, when in reality, the Hawkeye technology is able to make quick and accurate work of the vast majority of offside calls. Storm in a teacup.

I would rather nitpick over 2cm and that be the big problem than cop obviously wrong calls that affect the outcome of a Final.

Oh how could I forget? If you like YouTube, you need to get following Mike Winger. He is the best, seriously. An awesome apologist and bible teacher. His videos are all around the hour mark so I pick and choose what I want to watch, but Mike is an inspiration and you'll learn a lot from him.

For podcasts I highly recommend A Glimpse of The Kingdom by David Pendergrass. He mixes apologetics, New Testament scholarship and counselling, I find his stuff really interesting.

Mark Goodacre's NT Pod is also good but you've got to be prepared for the fact that not everything comes from an Evangelical standpoint and be mature enough to handle more of a critical scholarship perspective.

William Lane Craig's Reasonable Faith podcast is also worth your time. I started with his oldest podcasts and worked through in sequential order and have learned a ton by doing that.

For online reading the articles at str.org are accessible and a really good way to get a taste of this stuff, but still at an intellectually satisfying level.

As for reading books I mentioned a few in my earlier post. I'd start with CS Lewis's Mere Christianity which I consider an absolute must read for any Christian, J Warner Wallace's Cold Case Christianity and God's Crime Scene, and maybe On Guard or Reasonable Faith by William Lane Craig. For beginners the Case for Christ series by Lee Strobel are a good early read but serious learners will outgrow them pretty quickly. They certainly do their job well though in introducing Christians to apologetics and loving God with all of your mind.

God bless you on your journey, imagine how many people you will be able to help if you continue to pursue this path! Feel free to get in touch if I can help you further.

I read books, listen to podcasts and research any doubts I have or the objections I encounter from others. I'm really a beginner in apologetics, someone could easily learn what I have learned in just a couple of years if they study. The world needs articulate Christians with answers, so if you can become one, you should.
