David's disturb circuit can be done as a daughter board that hooks up to pin 3 of the "Smooth Range" pot instead of tying that pin to ground! If you look at the disturb circuit, it will be at ground if no input signals are supplied. Add 12 resistors, 1 pot, 2 diodes, and an IC. Or just use one disturb input and drop the pot and 4 resistors.
Question: How do you properly connect the unused section of the LM324 in order to prevent it's causing any issues? |
but how is it powered properly? looking at his schematic, i believe he uses pins 4 & 11, but it doesn't specify what it goes to. i tried to find his email online, but was unsuccessful. 
any idea's anyone? |
Have not looked at the schematic, but the 324 can be operated off single OR dual supply. Pin 4 gets +V while pin 11 gets either -V or GND.

hmmm...
i set it up according to the datasheet, which seemed to state it takes +V and GND (not sure where you have the info on the -V).... and this isn't doing anything. the disturb is doing nothing to the woggle from what i can tell.
if you can actually add the -V to pin 11, should i just do so, or if it was intended for GND, could i kill something in the circuit?
other than this stuff, the wogglebug is freaking brilliant! i am getting the wildest stuff out of it... except that i can't get any noticeable change using the "cluster" knob. i wonder why this would be dead and all other things seem to be working perfectly... |

The LM324 can handle a 32v differential. So it is powered off of the +/-15v (30v differential). Thus 4 goes to +15 and 11 goes to -15. That's why the 100k pull downs to ground on the inputs. No input will see 0v, and the output will be 0v, thus not disturbing the Disturb beyond the offset created by the disturb pot.
In the group buy board, the 'woggletone' 4046 has pin 12 tied to ground thru R28, and pin 11 tied to ground via R12 and V2. The mod is the circuit with Dave's LM324 at the end of V2 instead of ground, a pretty easy change to make.  |

thanks for all the info!!!
i have not been able to get disturb to work at all. ugh. that and the cluter knob from the #3 design do nothing, yet everything else works. so frustrating!

If the cluster know isn't doing anything, look to see if there is a problem with your Sample&Hold circuit somewhere. U2 pings 6&7, D1, D2, U5A, R6, & R7. Maybe there is a solder bridge or diode inserted wrong? |

Maybe that could help. Dunno if u already done that :
"a small cap is required. 2.2nF or something close (4.7nF would be
ok) should be connected at one end at the junction between R35
(470ohm) and pin3 (round pad) of the cluster pot. the other end should
be connected to ground. a good place to do this is on the bottom side
of the board near the cluster pot which is also right next to the
lf398 sample/hold chip. this is missing on the original schematic but
some lf398s may work without it. On mine, it would not accept feedback
(the cluster setting) without this change."
From Ryan Williams paper on wogglebug.

this seems to have worked! now on to the disturb function and i am ready to rock. many thanks for pointing me at that data. i had read it and completely forgotten about it. |

Glad it worked !
Keep us informed with your progress on the disturb fonction.
cheers

THE PCB ARE ORDERED AS OF TODAY (11/29/07).
I WAS ABLE TO NEGOTIATE A BETTER PRICE, SO WE WILL
HAVE A TOTAL OF 160 BOARDS AVAILABLE.

| regarding the disturb function, i was never able to find a place to connect it into the design that yielded much of anything. i have decided that the "child tones" of the original are one of the coolest things ever... so i am inclined to build a second woggle and work on getting those instead. seems like a much bigger gain for the effort.... |

If you check at http://diy.czmok.de/Group-Buys.66.0.html I think you will find that you can still order boards. But I sure would not wait |

| Just a quick question - how does the 'cheaper price' work for those who have already ordered (and paid) for their boards? |

Well. I am just getting 150 boards for the price of 100. It it probably a _minor_ price change, BUT the dollar <-> euro conversion rate is eating it up fully, as i calculated originally with a rate of 1.32 USD/EUR and now it's 1.49 USD/EUR.
Literally it is compensation. Unfortunately  I am not gaining anything out of it, just no loss of money.
Groupbuys at such scale are difficult to handle with the current up/downs of the euro/usd conversion rate as i have to pay stuff in euro and many people pay in usd.

Boards are in production, just in case somebody might ask 
I just bought a silk screen set, so i am (theoretically) should be able to do
designs for dotcom or other panels.
Is there any interest in a dotcom frontpanel for this ?
Not sure yet about the prices.

Any chance of a frac or euro? |
Well. If you organize the material (black aluminium) i might do that as well.
its no problem doing silkscreens.
sidequestion: any interest for those as well ?

No. MOTM is out of interest for me because of the lack of front panels for it.
(maybe bridechamber/stoogepanels can help out with that).

Okay.
As poor old Dennis already knows, I've got an original Wiard Series 300 (300?) Wogglebug- the very last one ever built I believe?  (and if I ever sell it, Dennis gets first refusal!), but it's a hard bug to part with (which I'm sure Dennis would have great sympathy and understanding for- wouldn't you mate?  ).
I bought my Wogglebug on the strength of the above mp3 sound. But to be honest, however 'mad sounding' it is, it NEVER sounded like the above mp3 sample. I don't know why, but no. It doesn't. I've emailed Mr Richter, but Grant has never replied with an explanation
So be warned- or more to the point, if you know the tweak that makes a Wogglebug sound like the above 'monster from the ID' sample, please let me know!. I'd love to know!!
PS, the wogglebug sounds mental when wired up to an ms20!
