Boogie -- what software are you using to simulate or approximate the sonic characteristics/waveforms/behavior of circuits? I noticed that here and in previous projects that you are often comparing waveforms of circuit simulation and actual analog design (almost like a sanity check)?

Hello, the samples were recorded from the one on the left, the MRK I.
Cheers!

hey makhho

The software you see here is NCH wave editor.
I use it to analyse audio files.
The waveform by 'schematics on the internet' is not simulated, but a logging of my original design which was according to the 'schematics on the internet'.

When that turned out not to fit the audio extracted from the youtube movie, I went to simulation to find out about some characteristics (but not all, as e.g. I could not find a Spice file for the 566).

So all plots in this thread are audio plots.
In the MiniP7 thread I first did almost the whole 'equivalent' schematic in simulation before even thinking of drawing a chematic to create a PCB.

For this one it was the other way around.

The software I use for simulation is a (one of the so many) regular Spice simulator with some nice IO features like a 'speaker' out. One can realy play the output waveform on the speakers.
It's TINA. Not owned by TI but they provide a freeware version as to simulate their chip's models. The nice thing is, you can import whatever spice model and make a macro for it. So it's almost limitless.
You can find TINA here: http://www.ti.com/tool/tina-ti?keyMatch ... Everything

hello syntherjack
thanks for the feedback.
It's a bit strange that it does differ so much from the video I reffered to, as it's the same type. Both MK I.

Here's a small disclosure of my findings.
The one I analysed uses the square wave output of the 566. One needs the square wave to end up with the waveform in the video.
In contradiction to that, the 566 waveform used to create the samples you provided are clearly the 566 triangle waveform.

I (and some other MW via PM) have seen strange things happening in the digital as well. e.g. where the datasheets clearly direct one thing, but the PCB clearly did not follow the datasheet.
I have the feeling that Mr Simmons designed some versions with quite some differences although they carry the same name.

:chug: to all.

Following this. Would love a PCB/panel when they come out they're ready. Or if you do a second prototype run!

price indication

Post by Boogie » Tue Jul 10, 2018 9:37 am

Hello all,

sorry for having been away for a while.

Below is a first price setting,and a list to add your name to if you're interested.

For those who have alreadye expressed their interest and may want to review their preference, pls feel free to update the list.

About extrernal controlling some parameters,
Combining the trigger inputs into 1 trigger input feasable to trigger on 5V-12V trigger and on audio, there now is a possibility to provide two external CV's.

Unfortunately, there are more controlls then 2.
I would propose to make the Noise decay and tone controllable.

I'd love to get your feedback on this controllable stuff, but be aware that the more one wants, the more expensive it gets.

As the pot meters are upside down, I will be offerig the knobs in the kit as well as they come from RS components.

Kit 1 cost €41.20 excl vat and excl shipping
1 x Bare PCB
1 x NE566
8 x knobs (2 Red, 4 Yellow, 2 white) stripe

Kit 2 cost €80.50 excl vat and excl shipping
1 x Kit 1
1 x Black anodized FP with white overlay from Schaeffer

I'll publish the FP file and overlay file Julian can work with for those who prefer to order Kit_1.

I will also check for another manufacturer's prices on frontpanels.
If that turns out to be lot's cheaper compared to Scheaffer, then I will update the price on Kit_2.

The list of interested people is in the next post.

Dope!

What kind of switches are those with the grey keys? Are they available from Digi-key or Mouser?

Just to clarify, is this redesign the version with more CV inputs?

This is the redesign with 2 CV inputs.
I've selected the Hiss decay and Hiss tone to be Voltage Controlled.
As I did not start the redesign yes, I'm willing to change that to something else, but limited to a max of 2CV's.
For now that is: CV1 - CV2 - Trig - Out

@ Everybody, pls feel free to provide your preference for the two CV inputs.
I'll certainly take your input into account when I start the redesign.

I would like one of the redesigned kits + panel then.
I think Hiss decay and tone are good choices for modulation.

@Boogie Any chance of turning the pots 180 deg. so D-shaft pots can be used with the more common knob pointer orientation?

toneburst

unfortunately, no.
It's my standard and functions perfect with the Sifam knobs which are also my standard.
That's why the knobs are a part of the kit.

Sorry.

That’s a shame. I’m not a fan of those knobs.
I’ll replace the pots with T18 versions, in that case.
