VFE Projects / Re: Question about the 12F509 micro controller.
« on: September 13, 2019, 05:17:04 AM »
The same micro-controller is used in all VFE effects. The difference in the Standout is that the relay is a non-latching one. Check the build documentation for the exact part.

Not a mechanical switch like a 3pdt. But, a relay based system that uses a normally open momentary switch you can.

General Questions / Re: Sometime circuits squeal, sometime not

Have you tested this phenomenon someplace other than your home?

I ask because I experienced something similar. Sometimes I would get horrible power supply buzz, sometimes it would be fine. I discovered my apartment has such horrible grounding that any time any of the air conditioning units in my "stack" (my room and the two above me) were running, I get power supply noise. If they're off, its fine.

Well, as fine as I ever get, there is so much EMF noise around here that I can barely use wifi 2ft from my router and my wireless headphones go buggy walking across a room....

Given that I live in Arizona, it means I prefer battery power 10.5 months of the year  ;D

This is a crucial point. Always test other outlets that are on a different breaker and different power supplies, if possible. Some mains wiring is just noisy. In my house in Austin I had one outlet that was noisy as balls and other ones that were fine. I've had one Boss PSU that turned into absolute garbage after years of use.

Scruffie is pretty much the master of the BBD!

It's all fun and games till you need to find a replacement knob...
Largebear carries them, I bet.   ;D

If anyone gets this....

Call me when it's in the round with several tiers and you need an elevator to turn the pedals on.

Bummer the new boards didn't materialise this weekend :( hopefully in the not so distant future! I will wait with bated breath :)

I think the two Man O War docs will be up tomorrow, and then I will shoot for the Polytrog and Bumblee docs on Wed. So, if all goes well Thursday will be the day. I seriously gotta get this wrapped up - I have about 10 prototypes for future projects waiting for me, haha.

It might just be bad luck and you got a couple BBDs with shorter delay time. It's never exact, but 420ms is quite low. Only thing I can recommend is on your next parts order is maybe pick up a couple more v3205 and another clock and see if you get a better result. If you have a frequency measurement option on your multimeter, set the delay time to max and check the frequency reading on either CP1 or CP2. I forget what the target is exactly but it's somewhere between 6.4-6.8kHz. If that's what you are getting then it's your particular BBD set causing the shorter delay, IMO.

It's in the Switching doc.

Open Discussion / Re: LDR photoresistor

Generally directly at the LED. The only case where I don't do that is when I have multiple LDRs keying off one LED (like in an optical phaser). In that case I usually flush mount the LDRs and use a light shield.

Tech Help - Etcher's Paradise / Re: EgoDriver/Fulltone OCD architecture
« on: September 06, 2019, 05:39:52 AM »
In general, the distinctions between overdrive and distortion tend to fall into these criteria (IMO):
1- Overdrive is meant to compliment and enhance a tone that is already in or near breakup.
2 - Overdrive retains some element of clean signal layered into the clipped waveform.
3 - Distortion doesn't require 1 or 2.

The OCD is an overdrive by that definition. However, I would consider a Rat more of a distortion even though it has some elements of 1 and 2 and is pretty similar to an OCD. Both have non-inverted gain stages which means some clean is layered in the result. But, they sound radically different.

The biggest difference (again, IMO) between soft and hard clipping is that hard clipping can be more responsive to picking dynamics. For example, in the OCD you can actually get a fairly clean sounding signal if you pick very lightly. As you increase the picking dynamic the output clips proportionately and the overall perceived compression increases. This can also be true for overdrives, but sometimes to a lesser extent.

Then again, I don't think these are very important or needed distinctions.

Errata, Corrections, Revisions / VFE Focus wiring correction
« on: September 05, 2019, 04:42:36 PM »
On the wiring diagram I had the wires shifted to the wrong pads on the audio PCB. The build pic showed the right connections, however. I've updated the pdf and zip files with the correct wiring.

... you cook for your dogs?

Wow, Dad used to have a dog, and the only time it got cooked food was when we had leftovers no one wanted.

Indeed. We found that cooking their meals was much cheaper than buying dog food (and ultimately healthier). We cut our monthly dog food budget in half. About every 5 or 6 days I put a few chicken breasts with peas and carrots in a roaster and let it cook for a few hours. They love it, actually. One of them is getting pretty senior and we are trying to put more weight on her so meatballs are the new thing.

I'm not one to give into turrist demands (or tourist demands for that matter) but I really need that solder paste. So, I have prepared a batch of meatballs for the abductor. Tonight I will place them in the backyard per the ransom note and hope for the best.

Normally these are made for the dogs but since they have been eliminated conclusively as suspects I will give them a reprieve.
