Hi bob,
the WSG is very simple but there's some flexibility that means not every component goes into every WSG.
R1 connects the output from the noise generating circuit to a jack before going through the filter. Lorenzo's doesn't have a pre-filter output, just a post-filter output (i.e. where R16 and C10 connect to the jack) so R1 is not needed.
Similarly, you can duplicate the entire pre-filter section, so you get 2 wsg's in 1. The duplicate circuit (which Lorenzo's design does not incorporate) would connect to the pre-filter output with R2, hence R2 isn't included. The 2nd circuit would then connect to the filter via R3 (hence "from second circuit if needed" on Ray's schematic), so you don't need R3.
Hope that helps, good luck

OK, I think my little brain can start to digest that, thanks. (I think someone put a "Starve Knob" on my brain....then broke the knob off)
So I can assume that all of the other values for resistors and capacitors are the same?
ALSO: What if I just post a list of all of the parts I have laying around, and then you folks could tell me what I can build with them?
AND, Nice job with the CDROM drive! Thats pretty creative!
Cheers

Yep I'm pretty sure all the other values are the same as Ray's list (with the addition of Rk, the LED, and the volume pot, as mentioned in the info)... and as Ray mentions a 10% variation in any of the values won't matter, maybe you can cram in things you have lying about!

Joel,
Your CD-cased WSG is very cool indeed. How did you put on the labels and dial markings, etc? And what do they all mean ('Mod 1-2 freq', etc)? Have you added a few extra mods of your own?

Hi YoSynthi,
thanks for the feedback! My WSG was built using Uncle Krunkus's stripboard without any mods - I just labelled everything up as I wanted to be a bit clearer about what was going on!
To put on the face markings, I designed the front panel using the free Front Panel Designer software from Front Panel Express, then printed out from "outline mode" (to get black on white) and photocopied onto acetate - then I just trimmed it down, cut out the holes, and screwed it down using the pots and switches.... the front panel file is attached, feel free to muck about!
The labels are just what seemed logical at the time, so mod 1-1 and mod 1-2 both modulate oscillator 1 etc... the pictures here and here really helped sort out what was going on
hope that helps! Joel
[EDIT] can't seem to attach front panel file, pm me and I can e-mail it! [/EDIT] |

Joel,
I received your front panel file via PM, no problems. It's inspired me to have a go with a couple of things myself. Thanks again! |

Here is my completed WSG cased in an old Radio Shack phone.
Details: I used uncle's stripboard layout
there are 3 switches, one SPST on the front of the phone, another uses the line one line two button on the right hand side and the final switch is activated if you pick up the phone.

Very cool indeed.
Now to incorporate the number buttons into the circuit somehow.
That would look great being played live. _________________ What makes a space ours, is what we put there, and what we do there. |

ABSOLUTLY AWSOME!!!!!!
I still havnt finished my WSG yet ;(
My brain just becomes jello (Or Gelateno) when I dont have a PCB with an easy layout to just start soldering things in to.
Has anyone here invented a PCB that they'd sell (Or donate to a broke dork like me?)
The little PCB kits they sell at rattyold shack are tiny, and good for nothing. And I havnt found a good way to transfer a decent circuit image to the board for etching. |

layout done in eagle Subject description: please help look for any errors |
|

Hey all!
Below is the layouts i did in EAGLE freeware version. I'm doing this so i can shrink the available board to the minimal size by offloading the pots, switches, and output jack to the panel face.
Now i've gone over the pdf of the schematics and cant find any problems. But i could use a second (or 3rd) set if eyes to look it over.
please point out any errors if you all don't mind.
Maybe if its ok, when i'm done i can get a few boards made for others, i'm trying to put it in a 3"x5" case
Please give it a look
Thanks!
ADam
I found one already. The cap , battery, and power switch are in the wrong order.

WSG: The Gateway Synth |
|
|
Oh Buddha, the WSG has hooked me on DIY synthmaking. Did Mr. Wilson design this as a way to lure new blood into the scene? Perhaps a shrewd marketing ploy to sell Soundlab PCBs?
I'm still in the process of casing mine up, (can't seem to stop playing with it long enough) and deciding if/how to add an input.
The info I've found here has been endlessly helpful. I think I've learned more in the last week than I have in the past year. Thanks! You've got a great community here. _________________ - Collin Mel |

I think Ray wants to promote DIY synth building, and he is too schrewd to think you can make any money selling Soundlab PCBs. He's in it for the fun of it, like most of the rest of us. _________________ --Howard

I'm waiting on some parts that are "out of stock" damnit! Just one question, I got some capacitors that are Wima orange, and are 5 spots long, yet the diagram want them put into 3 spot-distances apart. This means my caps are too long, can I mount them remotely, and connect them to the veroboard using bellwire? |

In general that is not a very good idea, if possible I'd advice to bend the legs and mount them where they should be. Using long wire might introduce unwanted inductance and the construction would be susceptible to picking up unwanted signals. _________________ Jan
also .. could someone please turn down the thermostat a bit.

That thing looks like it fell out of Fifty Foot Hose's touring van! Excellent work! I love the look of that thing, especially the vintage tophat knobs! A+! |

Thanks! The feedback is much appreciated.
Seems like the perfect "intro to synths" project for me. The humor in the schematic really helped to break the ice. So much fun - I'm gonna take a stab at designing a baby synth of my own. _________________ - Collin Mel |
