Any comments welcome ; i am looking for help in PCB manufacturing for this disto module

Re: Overdrive Distorsion : simple circuit
Hi julien, nice job!(already told you on the other forum ).
what kind of help do you need:
schemes/gerber files?
pcb manufacturers info/contact?
someone to run a group buy maybe?
btw.
are you feeding the overdrive circuit with the x0x psu?
what else does it need, on/off switch, overdrive amount pot?
and please share the pattern notation on the third video, it's groovy!

i've done the eagle .sch. I 'd like someone make the .brd in order to make a bulk order at opencircuit or something like that.what kind of help do you need:
schemes/gerber files?
yes, Vcc and Vssare you feeding the overdrive circuit with the x0x psu?
it has an ON/OFF for overdrive, a pot for disto amount and a switch for "Gate always on"what else does it need, on/off switch, overdrive amount pot?
.
The more the signal is overdriven, the more the led is bright (heartbeat style).

Re: Overdrive Distorsion : simple circuit
thanks for the pattern, just played with it , it's amazing how the reverse mode brings even more groove to the x0x.
some more questions:
is there any audible noise with the distortion? seems like there is no extra noise on your videos.
btw, on your latest videos looks like you already stuffed all inside your x0x, it was easy to make all fit?

Re: Overdrive Distorsion : simple circuit
absolutly no noise when no VCO , only crosstalk of x0xb0x ! ((centered position for SAW/SQUARE ; btw, why haven't you referenced that mod x0xers ?? how to do a so simple audio in to filter ??)is there any audible noise with the distortion?
i should mesure it, but the device is not in my flat.
on veroboard it is exactly 2x the area of a SUB D25 ; on a dedicated PCB, it can fit 1 DB25 (including screws and spacers)looks like you already stuffed all inside your x0x, it was easy to make all fit?
People interested by a PCB or Kit ?

Re: Overdrive Distorsion : simple circuit
judging from the pcb layout the circuit looks simple enough to easily build it on stripboard.
i doubt that a professionally manufactured pcb is necessary here - too expensive, too much hassle (mind you: collecting money, ordering, packaging & sending out the boards, making sure everything goes smoothly and no one gets pissed off etc...).
if you want me to i can whip up a stripboard layout over the weekend for you - this way everyone can build the overdrive without commiting to a pcb run.
just my opinion, but i really think this is the best solution, as you'd make both the guys that can etch pcbs and those who can't happy.

Re: Overdrive Distorsion : simple circuit
i have no idea what you want to say with this statement - stripboard is a great way to put simple circuits together -julienvoirin wrote:is the biggest swindle in electronicsstripboard
and with a stripboard layout anyone can solder circuits. just make the necessary cuts and follow the component placement layout, no need to etch a pcb (or order one). you can get pretty complicated as well, the MFOS soundlab minisynth is available as a stripboard layout...
so please, oh high and mighty electronics wizard, enlighten me with your most sophisticated knowledge. or not. i dont care too much either way.

Re: Overdrive Distorsion : simple circuit
stripboard is "un attrape couillon", veroboard is the thing.stripboard is a great way to put simple circuits together
i wouldn't say so, it has a PCB. And it sounds bad.MFOS soundlab minisynth is available as a stripboard layout...
i do not need your services, and i won't share my knowledge with you, especially you.so please, oh high and mighty electronics wizard, enlighten me with your most sophisticated knowledge
EDIT : what a jerk ! now i remember why I removed the schem
pinheader SV1 :
amount : 10KB pot
pin1 goes to pad+ of c38
pin2 goes to pad- of c38
pin3 goes to free leg of R133
pin4 goes to +12V
pin5 goes to ground
you will have to remove C38 from the x0x PCB mainboard, and reuse it in the circuit (or a new one)
R4 should be adapted to your design (e.g 10k) in order to get same level within and without distorsion
PCB won't be shared to dic**eads.
Notice i do not allow you to sell x0xb0x containing my disto without a tip

Re: Overdrive Distorsion : simple circuit
Not sure what you were trying to accomplish here creekree, julien just asked about interest in a PCB or Kit run as he wanted to share his knowledge in that way, nothing else and nothing more, what's extra noise about?
Thanks for posting the schematic julien!

Re: Overdrive Distorsion : simple circuit
sounds nice. would this work if the bcbox i/o mod has already been installed, or is it only for a 'clean' x0xb0x?julienvoirin wrote:all is ready : PCB designed in eagle, part list and of course schematic

Re: Overdrive Distorsion : simple circuit
of course, the circuit has to be inserted at the place of condensator C38would this work if the bcbox i/o mod has already been installed,

Re: Overdrive Distorsion : simple circuit
you can install it alongside the x0xi0 kits.
The two distortion circuits built into the x0xi0 are post volume control and 'mixer'. The input signal is taken at the main output (mix out) of the x0xb0x.
The x0xb0x volume control is the de-facto input level control to the circuit.
The overdrive described here is placed at the output of the VCA before the volume control and before the x0xb0x discrete mixer circuit.
You could install both and use one or the other or both at the same time.

Re: Overdrive Distorsion : simple circuit
the idea was to still have the audio in available for my drummachine and the distorsion in the headphone too.The overdrive described here is placed at the output of the VCA before the volume control and before the x0xb0x discrete mixer circuit.
"Clever idea, isn't ?" would say the mighty wizard
just for the pleasure :
