Whacky, Zany, Weird Stripboard Layout

Uncle Krunkus · Posted: Sun Jun 25, 2006 4:46 pm Post subject:

On the schematic you'll notice that Ray said there are three inverters spare on the 40106 and you could make a second channel. For the stripboard layout I included the parts for the second channel. You end up with 5(?) more pots, an extra switch etc.

Ah wicked stuff, i'm starting to get it now. I did electronics at school (i'm 20 now) so i know what the parts of the diagram represent etc - just need some revision to get the basics going again i think Smile

.

Dnny if you could draw me up the strip board with Led (resistor for the LED too Wink

) and Volume switch i would be most grateful. Very Happy

I see the difference now on the parts list, its because it uses the spare inverters... thanks Uncle Krunkus.

So i take it that parts list is all i need to go out and buy along with an LED, volume pot and a resistor for the LED? And some wire for the connections on the strip board and to connect the pots, switches etc to the box that i put it in.... I hope thats right - if so i'm learning a little more... woohoo - It should be interesting when i start to build it Laughing

Thanks again for your help.

Peace

Kindest Regards

No worries Steven,
It's great to know that someone else will soon be gettin whacky wid it! Shocked

Hey Uncle don't suppose you post up a pic of your WSG -would be cool to see it!

Does the strip board layout use one 9v battery placement or two?

If i'm reading it correctly i'm thinking one?

Cheers All

The only one I've made I've gave to a friend of mine for a birthday present. I might have a pic of it somewhere but I can't find it at the moment. I'm going to do another one for my daughter when I get a round tuit.
PS yeah, just one 9V

Hello all
Well, my WSG is half way to being complete - i have really enjoyed it so far and thankyou all for your help.
I have a couple of minor problems that i hope you can help me with.

1. C1 MKS 2 / B=2,5, 100nF I have this component but it is not a MKS 2 - its a MKS 4 i think. I had to solder on some wire to the legs of the component to solder it to the board - will this effect the machine?

2. C10 on the strip board diagram (top right) it does not say what way round the + and - are? I guessed + to be facing north as i believe the current flows from + to -????

3. The pots and switches around the board diagram do not say what it does? Could anyone let me know what each pot and switch on the board does - would be most grateful. Also what legs get soldered to the board?#

4. On the jack output could anyone tell me what legs get soldered to the board and where because on the diagram it shows only one hole that gets soldered - is this correct.

5. Could anyone help me out with a diagram (or words) on how to add a volume pot, an LED to show that the machine is on and the resistor to protect the LED??

Thankyou people, cannot wait to see if it works!

Peace

Kindest Regards

Steve

1. ignore all that mks stuff, it's just a 100nF cap, greencap, mkt, etc.
2. C10 is supposed to be a non polarised electrolytic. (will have NP or BP(bi-polar) printed on it, doesn't matter which way around)
3. the 100Ks with 3 connections are as laid out (sides to sides with center to the center) the pots with 2 connections are 1 to the center and one to one side, depending on how you turn it. (you'll get the idea once you start playing around with pots)
4. The output is just the one wire to the tip of the cable, the sheild of the cable is connected to ground.
5. A good volume pot would be a 10K. Circuit to each side and output off ground side and the center.
6. For a power on LED put it across the battery (9V) with a 1K resistor in series.
I've had a few beers tonight, so I've made this quick and simple. Any hassles, post back and I'll sort it tomorrow! Cool

BTW you won't need a LED to know that it's on!! Laughing

Wicked stuff thankyou so much!
Only one other thing and that is what does each pot do?

For example;
What switch is on/off, and what one makes the envelope slow and fast?
What pot(s) controls the frequency?
What pot(s) controls the 2nd modulator and what controls the amount?
What pot(s) controls the main oscillator frequency?
What pot(s) controls the filter cutoff frequency?

Thankyou all - its nearly there woohoo!

Kindest Regards

Steve

The filter is the one at the top (near the 741)
For the other ones, there's a picture on page three of this thread that shows what's what.

Oh yeah how did i miss the pic?

Thanks Very Happy

Should be able to test this thing tonight, i hope it all works Embarassed

I will let you know the progress, cheers

Peace Cool

Please find below some questions I asked earlier:

So I've ordered parts for the WSG project, but I have a couple questions.

Firstly, I am a fan of stripboard and am interested in doing this layout, but I'm slightly confused about the second channel. Is it for stereo output?

Does anyone have a breakdown of the different knob functions for the individual positions (on the stripboard layout)?

Sorry if these questions seem elementary. I have built a lot of pedals recently, but this will be "my first synth" and I am very excited about it. Any information you can forward me would be great.

By the way, am also interested in the Scott Stites vactrol mods. They sound great. Any recommendations for offboard modding the stripboard layout and from what postition?

Thanks again.

Funny how a little bit more research will provide you with the answers. Anyway, wish me luck on this one, the parts should be in from Futurelec next week.

Hi somasix
the second channel ads tree more oscillators. the WSG is still a mono.

Hey Daniel,
I can't work out what IIRC means. Embarassed

Thanks for the quick replies everybody. A little research goes a long way. I'm beginning to get a feel for the layout of the forum.

I'm looking forward to starting this project as the parts come in. Thanks for the support.

good luck Jason.
when you get it up and running please post a pic of your WSG.
if you have more questions don´t hesitate to post them here.

Thanks for all the help. I can't wait for my parts to show up. This is going to be great.

Now that I know how the second channel figures, I'm doubly excited. I look forward to seeing how they interact with one another.

Definitely expect images when I'm done. I'm going to attempt Scott Stite's Loony mod too. Ordered the vactrols and everything. His sound files of this mod just can't be beat.

Best.

Thanks for the diagram dnny - most helpful.
Been real busy this week, got the day off today so i'm gonna try and get the little beast going.

Thanks

Kind Regards

All right, so I got most of my parts, but I plain forgot to order a few parts that I've yet to run into in my journey into electronics. Those would be:

2nf capacitor (non-pola I'm assuming)
and
100nf cap(likewise).

Is there another way to refer to these components? I'm having trouble finding them through futurlec. Thanks everybody. I wish I could start on this today!!!

Uncle Krunkus · Posted: Sun Jul 16, 2006 4:45 pm Post subject:

Your magnitude prefixes for caps go like this: -
picafarad - pF,
1000pF = 1 nanofarad - nF
1000nF = 1 microfarad - uF
the use of nanofarad is more prevalent today than it was say 15-20yrs ago. I think, (anyone correct me if I'm wrong) the idea of using it is to reduce the number of digits used (especially multiple 0s)
So instead of writing 5700pF, or .0057uF we now use 5n7 or 5.7nF (the 5n7 is another new idea which eliminates the use of decimal points. (which could easily go missing over a fax transmission, (which is obsolete now anyway! Surprised

)))
So,
2nF = .002uF (EIA code = 202) and
100nF = .1uF (EIA code = 104)
EIA codes tell you how many pF in the same way that the resistor colour codes work, ie; 1st digit, 2nd digit, number of 0s

Thanks for clearing that up for me Uncle Krunkus. I appreciate the help.

All right, after a long absence from personal projects, I populated the stripboard layout for the WSG. Alas, another total failure. This has been the second project that hasn't worked in a month. Here's what's going on, virtually nothing...

except, the smallest sound, like beavers chewing, under the hum of my amp. Anyone got any ideas?

Help please,

Jason
