Does anyone have a PCB layout for this? I tried the link towards the beginning of the thread, but it no longer works. Thanks.

vtl: which schematics does this PCB refer to, please? i'd say it's not the original wiard version as linked in the first post of this thread.

It's mainly based off the wogglebug #3 schematic ( http://www.musicsynthesizer.com/WoggleBug/WOGGLSCH.GIF ). I added a second RM output and a sync input to the 555. The latter is based off of one of Rene Schmitz VCOs. ( http://www.uni-bonn.de/~uzs159/vco3.html )

ok, thank you. i asked because on the two PCB pictures above there are e.g. two transistors without any specification. the wiard schematics contains one of them and the other one i guess i'll have to look for in the VCO3 circuit you mentioned.

Right. The second transistor (connected to pin 4 of the 555) is for the synch circuit. Not essential, but I thought it would be a fun feature to add.

Thanks vtl5c3. That is indeed what I was looking for.

Here is my first round of queries on the wogglebug layout:

In the sync in area, is that a diode connecting to ground?

While we are over there, is the second transistor 2N3904?

As far as the capacitor types go i am resonably comfortable that C denotes ceramic, P is poly (-styrene? -ester? -propelyene?), T is tantalum. But what give with the FP and NP designations?

There are 4 pairs of pads left blank, I am imagining that several are for returns to V+/- and ground for some of the pots? Is this correct? There is a pair open just north of the 398, one side grounded the other jumpered to V-.

Does anyone have a handy list of the names for the potentiometers? I have been trying to work it out from the block diagram on the Wiard site to no avail. It would also seem that Grant's production model has a good bit more packed into it than his basic schem shows, such as the disturb CVs and a bunch of lovely LEDs. any leads on these extras??

Any and all light that anyone can shed on these issues is very appreciated. Im sure I forgot something I can bother everyone with later...

Yes. The anode connects to ground. For anyone that's confused about this section, please refer to Rene Schmitz's VCO 3:

http://www.uni-bonn.de/~uzs159/vco3.html

I copied the stuff on pin 4 of the 555.

That should work fine.

NP is non-polarized aka bipolar. Never heard of FP.

The 4 blank pads are actually for bypass caps (.1 or .01 uF) for the TL071. Same goes for the two pads north of the LF398.

The Wiard production Wogglebug is a more sophisticated version. I tried working out what was behind the front panel at some point... not sure where my notes are for that. I'm pretty sure a second LF398 is involved. I'll see if I can find my stuff. Obviously, Grant isn't going to give out his secret recipe. Despite the fact that the Wogglebug #3 is simpler than the production version, it is still a fantastic module. You could always start with that and hack other stuff onto it. The Wiardgroup on yahoo groups has some extra add-onn circuits that Dr. Mabuse designed. Might want to check those out.

These are good questions. I never realized that people would be interested in this layout, which is why the parts placement is still in its cryptic format. I'll try to whip up one that's more user friendly.

I am certainly interested! Even though I am backed up for about a month finishing old projects here... When I am more or less caught up I'm wanting to build a few low-pass gates and try some Wogglebug action. I was recently thinking of starting a layout - and here's one already! Looks good to me. But I'll likely be adapting it to perfboard. Thanks for showing us!

Richard Brewster posted his take on the Wogglebug yesterday. Looks very nice.

I am about to get my PCB etched for the wogglebug, but still i am puzzled on how it should be connected to the frontpanel ( i used the panel design from pugix.com for my MOTM, but that similar to the other one.

Is this correct ??????????

Pots:
STEP LIMIT -> R8A,R8B, R8C -> Value 50K
WOGGLE ->
S RANGE ->
W RANGE ->
DISTURB ->
RATE -> between GND/+15V and middle pot to jack RATE CV and then to CV Inputs

Jacks:

CLK OUT ->
STEP CLK ->
RATE CV ->
STEP IN ->
DISTURB A ->
DISTURB B ->
S TONE -> Smooth Tone on PCB
W TONE -> Woggle Tone on PCB
SMOOTH ->
STEPPED -> Stepped on PCB
WOGGLED -> Woggle Out on PCB
RINGMOD ->

I am completely puzzled about the Pots and the other connections on the PCB like "R13, R21B" ... and such (which are pad's on the PCB, NOT Resistors)

Any help appreciated.

The PCB that I posted is based on the schematic at:
http://www.musicsynthesizer.com/WoggleBug/WOGGLSCH.GIF

If you based your front panel off Richard Brewster's design... there's stuff in his version of the wogglebug that's not in the PCB that I posted.

Well. Brewster's design is just an idea, i'd like to get a fitting one for the
one here:

Let's see if i get the connections right :

R8 = 50K = STEPPED
R9 = 50K = CV IN
R13 = 1M = ?????
R19 = 1M = ?????
R21 = 1M = ?????

J2 = RINGMOD IN
J4 = WOGGLE OUT
J5 = WOGGLETONE OUT
J6 = TONE OUT
J7 = SMOOTH CV IN

Anything else i missed ?

Ah. Sorry. Keep forgetting that the pots aren't labelled on Grant's schematic. Here's the updated list:

R8 = 50K = Correlation
R9 = 50K = CV IN
R13 = 1M = Smooth Range
R19 = 1M =Woggle Range
R21 = 1M = Woggle Time

J2 = RINGMOD Out
J4 = WOGGLE OUT
J5 = WOGGLETONE OUT
J6 = Smooth TONE OUT
J7 = SMOOTH CV Out

I think that's it, unless you plan on adding the Sync input and second RM output.

I have built the Wogglebug#3 with the PCB posted here. But -- it does not sound like it should be.

There's only a high pitch one some, lower pitch on other, but it does not sound like it should be (according to the examples).

Can somebody provide me debugging tips on how i can nail down the problems ?

i ran across mark v's dual-wogglebug schematic again and thought i'd throw it into the diy-pool here:

PDF's:
http://sneak-thief.com/modular/woggle_bug_etch.pdf
http://sneak-thief.com/modular/woggle_bug.pdf


Mark's notes:

(these matter because this one is funky)

1. both PDFs are fromt he solder side. You are looking
at a reversed image of the parts.

2. There needs to be a jumper from the hole at pin 3
of the 555 to the one above the label "tri stepped".
This label is actually for the pad below it. I made
the board so that you could tap in your own clock to
the sample and hold if you wanted to. If you want it
to be hard wired, just jumper it.

3. The labeling was done in a senseless way. The
labels on the right side are in the margina nd the
left side are near the pads. It can confuse in the
middle, but you should be able to figure it out, since
the two halves are duped.

4. The power is set up for the standard MOTM
connector. +15 GND GND -15

5. the 3 pads next to the 398 are for the 50k pot that
controls correlation.

6. the "ring' jack is mis-labelled "rin"

7. the red rectangles are trim pots.

I've built this version, and many thanks to mark for sending it. Warning: there are a number of errors on the traces. I got it fixed, nothing too bad, but I'll have to pull it out and look. from memory the TL071 is missing it's power lines, and the 100K between pin 2 & 5 of the same chip should be between 2 & 6. I think there were one or two minor issues... i'll pull it from the rack this weekend and check.

as a guardian of the loyal order of the wogglebug, i can't reveal my 2 sources Wink

bbob - thanks for the heads-up! it would be greatly appreciated if you could let us know about any other issues with this board.

pulled out my woggglebug and notes, i think these are all the corrections i made (Red=cut trace; Green=added trace; blue=added jumper):

* added power connections to TL072
* re-routed 100k from pin 5 to pin 6 of TL072
* rerouted pin 8 of both 4042s to ground instead of neg
* grounded pin 1 of 555

these changes need to be made to both halves, i only drew them on one side (stupid paint).

happy woggling!

Given the "Original" PCB design on the first page of the thread here:

- I built the circuit
- on "W-Tone" i get a high pitch waveform.
- on "S-Tone" i get a low (maybe around 440 Hz) waveform.
- on Ring i get an output like "digital"

This is definitely not right. I already checked the PCB for obvious errors or solder where it should not been... found some, fixed all. still the same problem...

for the NPN's i use 2N3904, the rest is default. Resistor values are according to the diagram.

Just to get everything right: can somebody verify if the pots are done correctly or post me a short list ?

*sigh*

Anybody able to help me and giving me ideas where to look for (or measure).

Any help appreciated.
