|Warning <Your name here>, Warning... THIS IS THE OLD NOSTALGIC PAGE. You should go to the new and improved page...|
I have provided the following charts to help clarify HOW and HOW NOT to view the WSG and its capabilities.
Oh... and this is NOT a cruel practical joke this circuit really works.
Not content with wackiness, zaniness, weirdness and possible oddness,
Whether you need weird sounds for a movie, performance art, neighbor annoyance, or you just like making weird sounds in the woods this circuit is for you. You could put this on a radio shack breadboard and be up and making weird sounds in an hour or so. This is not for making musical sounds this is just for goofing around. Its actually pretty cool and does make some interesting sounds. I have been asked on several occasions to publish something like this so here you go... simple, small, cheap, battery powered, yet amazingly diverse as far as the sounds it makes.
Yes, you can even impress your friends who insist on wearing robot suits 24/7
by building one into your clothing if you are inventive enough.
People are turning this into a very viable project. It's getting a life of its own. Open source comes to synth-diy!

|Dave Wright is at this very moment making "Zany" sounds with what he has dubbed the "Schmitisizer". This is exactly the type of thing I envisioned for a case and I love the variety of knobs.|
|Dave's Dog contemplates the meaning of life and the odd sounds emanating from the "Schmitisizer". He only wishes he had fingers so he could twiddle the knobs.|
|Lorenzo laid out a PC board for the WSG and tested it too. It works
An astute observer (Dave Magnuson) suggested that the unused inputs of the CD40106 (or 74C14) should be stabilized. In CMOS chips this is done by connecting an input to either ground (low logic) or V+ (high logic). I have shown the additional traces to connect the unused inputs to V+. I changed the large layout too. Without this change the chip's unused inputs will float causing the unused gate outputs to oscillate and draw more current than you would like. In rare instances side effects may include: heartburn, next day dizziness or drowsiness, and abdominal discomfort.

The second channel components have the same designator as their first channel counterparts +20 except for R7/R3 which already had unique identifiers on the schematic. I went for the no unfiltered output option; therefore R1, R2, and C9 are omitted from both the layout and the list.
|Thanks to Fiercefish for making a composite layout from Andrew Sharp's layout. Now you can have XRay vision.|
|Hanne And Sakari from Locomofon have made some very cool versions of the WSG. Listen to their WSG.|
|Ron put his wsg in an old utensil box. He also added |
some extras - touch contact points, LED's and a meter to gauge the "weirdness emanating".
|Seb put his wsg in an IKEA key box after some negotiations|
with his wife. He added extras too - Seb decided to make
a MIDI triggered version and added a MIDI-to-gate converter,
ADSR envelope and VCA. Check out Seb's Synth-DIY Pages
|Alex Merck (music major at the University of Georgia) put his WSG in a Dick and Jane lunch box during a light hearted (perhaps wacky) moment. There is probably still room for a sandwich because the WSG uses so few components. Alex assured me that he purchased his own lunch box and did not wrest it from the hands of a younger sibling.|
|Well of course the eyes glow when the power is on... Yours don't! The illustration on the lunch box symbolizes that constructing a WSG is one of the building blocks of synth-diy success. See Spot synthesize. Synthesize Spot synthesize!|
|Could this be the next step in the evolutionary chain, or just a genetic experiment gone horribly awry? In any case it's one cool looking little sound making unit!|
|Further proof of the Synthopotamus' existence. They synth among us.|
|No... wait that headline should read Matthew Helm Adds WSG To His Video (Case). This is what I'm talking about. You see something in the room and triumphantly yell THAT is gonna' be my WSG case!|
|Matt's cat inspects his soldering and wonders where Matt put the previous occupant, a "Josie and the Pussycats" music video.|
|For the person with everything, here is a toy polar bear complete with a built-in WSG. Atilla and friend Furkan from Turkey built this unique creation. Proof once again that all you need are the "Bear Necessities" to have fun.|
|Proof that there is a WSG in there.||And even further proof for you skeptics.|
|Jorg shows that even a responsible environmentalist can enjoy a WSG if they make it out of recycled cardboard. I haven't seen a Coke can used yet but you know that's coming.|
|Save a tree... build a WSG. Hey that's catchy. Notice the high reliability rubber band holding the entire assembly together. I prefer baling wire and/or duct tape myself for high reliability work.||Give a hoot... don't pollute... make a WSG. Not as catchy. Jorg's pet alien enjoys spinning around on the pots and playing with the WSG too.|
|Everything this guy makes looks like something you could sell at Guitar Center!|
|Chub is an amazing electronics enthusiast. He made this for his grandson Malachi who of course brought it to school and well... OK its not allowed back... nuff said.|
|Thought you might like to see my WSG, built to Andrew Sharp's veroboard layout and with a couple of variations of my own - see the LDR in the top right corner. Hours of semi-musical fun! Thanks for sharing your design and congratulations on your most entertaining website.|
I went with the ever popular VHS case but since I used the stripboard
layout I've got 9 knobs and 2 switches.|
|All I can say is... "Ground control to Major Tom..." Oh yeah this is definitely standard equipment on any space music trip. Well done Leor.|
|Lord knows that milking cows all day can be boring. But not when you have a WSG built right into the milking can! The cows may wonder what's going on and the milk may have a bit of an aftertaste of ozone but hey... a true synthesist synthesizes under any circumstances.|
|Finland is a totally cool place with totally cool people making totally wierd music... well some of them. And Tomas is one. Here is his site related to the WSG. Yo Check Him Out: he is a certified, bonified, circuit bendin', weird music playin', 'totally out there Jerry' space music man. Tomas' WSG site|
|Neil Donoghue built a WSG using Andrew Sharp's layout. He called it The Yuri Gagarin Memorial Sound Generator and it's being used in his band Intermission To Saturn. It's built around a 1970s Logix Kosmos 'Super Electronics 1' project set.|
