Schematics :

Edit : I think I managed to fix it by changing the 2n5457's orientation (opposite from the pcb silkscreen).

I also added the modification I found here : https://www.madbeanpedals.com/forum/index.php?topic=31768.0

Hello,

I built a flintlock flanger some time ago, unfortunatly the signal gets very dark when I engage the effect, even when I remove the modulation by setting Threshold fully CCW, and Manual fully CW.

I tried to fix it myself without success by tweaking Mix and Bias trimpots.

On my build the sweep is set between 73 KHz and 2.2 MHz, to avoid distortions at both ends of the sweep.

In order to bias the clock frequencies, C-Range internal trimpot is set fully CW, and Auto is set fully CCW.

The volume internal trimpot is set fully CW to get the same level of volume when the effect is engaged.

I do have 15V at test point near IC11.

C37 is empty.

I did a recording so that you can hear what I mean by "dark" :

Any help would be welcome, I love this flanger and I have no idea how to fix it...

Three links from the British Medical Journal about the pandemic and the Pfiezer and Moderna vaccines

First link is the most important, published in november 2020, called "Covid-19: politicisation, “corruption,” and suppression of science" by Kamran Abbasi, executive editor

"Will covid-19 vaccines save lives? Current trials aren’t designed to tell us "

"Covid-19 vaccine trial protocols released"

What do you think about what scientists are saying ?

In France, two famous and eminent scientists are threatened to loose, or have already lost their jobs, because they are asking questions : university professor, hospital practitioner C. Perronne; specialist in infectious diseases, professor of microbiology D. Raoult. And many other less known health workers, hospital resuscitators, doctors, etc. Administrative hierarchy is doing everything to silence them.

Is it the same abroad ?

I'm old school.  I think the government wants to get society functioning again and I think doctors, in general, want people to be healthy and live.  I'm willing to have some trust in the process.  My wife is getting first dose of the vaccine this week.  I'll take it as soon as it is available.
With respect, that's not old school, that's naiveté, with a pinch of blindness.
I've been watching "the Vietnam War" by Ken Burns and Lynn Novick lately. I figure "old school" is quite subsersive and violent from what I can learn about the US in those days. We could use some of that ! Anti-communist ideologists and politicians had to fight two wars : the Vietnam and their own people, at home.

Governments call us "human resources" with few value. Doctors kill themselves or protest and get beaten by "police" (who wants to join them today, I mean the police ?) in the streets  because governments and industry won't let them get people healthy and living : how do you want capitalism and its brutality to thrive and prosper, if people are ok, healthy, and think by themselves ? This would be bad for business, really.

To paraphrase this... "We shouldn't trust science. Instead, we should pick the parts of science that support our preconceived opinions and ignore the rest. Oh, and confirmation bias is a conspiracy theory."

Science has always been hijacked by people with political or financial agendas. Once we justified slavery with science, segregation, etc. all that based on so-called "science". Do you know the "Atomic Red" ? Uranium lipstick from the late 1940's ! I guess people can be dead wrong...

"Conspiracy theory" is  a concept first publicized and used after WW2,  as an intellectual weapon by those fighting against former collaborationists and other fascistoid associations, willing to deny genocide during WW2. Capitalism and its friends are well-known for being able to promptly turn every weapon against their opponents : Now it's a common way to shut down criticism about everything, firing back alltogether honnest and legitimate concerns and childish phantasies and ghosts . Please don't go "Godwin-point " on me : this is an other way to kill democratic and progressist thinking, by destroying the one minimum point of agreement, from which people can compare with politics they are suffering today. Remember Rage Against the Machine ? "You got a bullet in your Head" ? Is that old school now ? I think so.


Looks like daily news aren't so good with this "variants" thing. Why Pfeizer and Moderna want every single governments to write into a bill of law that they won't be held responsible for any trouble with their fine vaccines ?

Blind faith in science is just as dangerous as religious belief and superstitions. It is my understanding that these vaccines only protect people from beeing sick. Vaccinated people will still carry the virus and infect other people. Even if the vaccine is what they hope it is, the epidemic will still spread, and mutate. This alone should make everyone wonder quite suspiciously.
If you aren't 80 years old and at the edge of death, or afflicted by some special health problem that makes you vulnerable to  a serious sickness, I can't see the point.
I can't see the point of getting it in everyone's arm, other than trying to reassure the whole world (and incidentally make a huge fortune).
Moreover, corona virus are constantly mutating, the pharmaceutic industry have no idea if this expensive and rushed vaccination campaign will have any results in the end on the epidemic. I certainly hope so, but hope can easily turn out to be delusion, at least with me.

Most side effects usually take years to show up, tragedies happened since the eighteenth century (Hepatitis B, 1995 or h1n1, 2011 for exemple). I am really concerned about vaccinated people's health in 10 years from now. And obviously sceptical about the efficiency of these corona vaccines, knowing it's impossible to find the one and only solution to a problem that's constantly changing. Hence the fact that the flu's vaccine never really worked (30 to 60 percent).
I really can't understand what's happening to humanity with this crazy "sanitary crisis".
I know for a fact that in France, confinements and curfews come from hypocrisy: it's only about NOT reopening all the public hospitals that have been closed for "economic reasons" during these last "neo-liberal" corrupted years. The government's "great health council" (newspapers claim there's more conflicts of interest in those councils alone than in the whole country together...) told us openly so itself ! French government is still silently destroying public hospitals and medical jobs during this crisis, in order to push people toward private medical establishments in the near future. The police crushed the Healthcare worker's demonstrations with much violence in 2019 and 2020. Looks like nothing can stop mobsters in expensive suits when they are protected by poor guys in uniform, armed to the teeth. May all DIY goddesses protect us ! Build your own vaccine ! Build your own brain ! Imagine that some guy puts you in jail for one year, without music gear, then he comes back and tells you the only solution for you to go back to your good old life, with all your stompboxes, is to drink a strange potion. Would you gladly drink it ? I would fake drinking it and find help to investigate this further once released from their jail ...or something ... Maybe modify the old multimeter into a great fuzzy laser weapon, connected to a powerfull tube amp to break their walls, release the other prisoners and see them return safely to their emg pickups and loop stations. No more strange potions !

Hello, I did it some time ago now.

The modulation does go down when i turn down the Delay pot,  I just increase Depth pot and i can hear the modulation again.
Following pcbguitarmania's instructions, I replaced the Xvive optocoupler by a red LED and a photo resistor.
My Pirate Shift is allright, except for background noises in the signal path when I turn up the delay pot.
GuitarMania told me maybe my guitar signal is too hot, I tried with passive pick-ups, but i couldn't get a clean delay . Any ideas ?

Hi,

I hope this is the right place to post this .

I've been trying to finish the pirate shift for two weeks now , beeing a beginner and all,  i can't cant manage to get the chorus into play.
doc : https://pcbguitarmania.com/wp-content/uploads/2018/02/Pirate-Shift.pdf
The delay is working, and there is a modulation when i keep moving a wire along both negative legs of the photo coupler (LDR1)
If i bridge them, depth pot come to life and some modulation appears if i keep turning it, but that's all, it won't hold.
The LED (D5) responds to Speed , Wave has no effect.

I know other people had this problem; they did something in the end to activate the chorus (a bridge somewhere) but i can't figure it out

Any help would be greatly welcome .
