Ahah yeah spaghetti box, it's exactly how I presented it ! Do i know you ? :) Well yes, surprisingly it works like a charm (at first start, was reaaaaally surprised myself) Not sure demo needed, everyone here should know it already, it's only a full modded arachnid. Well a fat modded one with...

Hi guys ! Closing this case : really stupid Noob error, following bad IC classic. Installed new 4049 from tayda : no More whistle but LOT of noise. Deep inspection... Doubt.... Look at my capacitor stash... No 1.5n... Weird... Look at the module capacitor... Fuuuuuu****** ! 15n ! *growl*...

Hi again, With reflexion and re-reading the build doc of the module clock and forum threads previously published, i'm questionning myself about the wiring (i know my spaghetti incident doesn't allow to see clearly things, but in fact only the wiring module / PCB is questionning). One (forum)...

Yes, it could be, except that I first tested it unboxed and clearly isolated. Same result... I'll go for another IC, could be à fake... Well, i'll go without for now !

Since it is full of mods it will Be unreadable (and suprisingly enough, it is working despite the spaghetti Nexus !), i have taken a photo of the module part, but Here again i doubt it will help but Here it is... I'm 100% sûre now that my wiring is correct and I have controlled the components...

It's me again, the whistleblower ! Came back from electronic store with a proper 4049UBE. Finally mounted my circuit and tested it finally, everything is working, except this whistle that is still there... First, thx for the build doc that you added, it allowed me to control and everything...

Pretty sure of That by now, found one at local store, i'll give it a try soon ! Thank you !

Hello there ! Tried with 3.3v and external 5v, same problem. I was wrong about the IC ref : its exactly a CD74HC4049BE. I guess it would be the real problem, don't have No other 4049 to test and I'm lost with references for this one... Thx !

Thx for the hint, i'll try the 3.3v (for now I desoldered à lot of things, can't test that immediatly, but i'll report asap) X is on the pad previously occupied by a cristal leg (the closest to fv1). A precision : i have mounted all this with a Switch to keep cristal option (with 2pdt) : the...

Hi ! Since there's no marks on clock module I have wired it following forum threads : "The pads on the clock module are X / GND / VCC" Left to right from components side, IC at the top (pads at the bottom, indeed!) It seems ok as tweaking results in moduling the effects (nice!) Well there's...
