Patrick, very well executed, looks quite prossional.
You have a great setup there.
Time to sell the S1 😎

You to thank in the first place.
Still looking for a good home for the S1.

Jan,
I believe you are no longer selling these kits. If so, would you be willing to provide schematics/gerbers etc to allow us to get our own PCBs made?

And also to provide full (and free of course) technical support when (any of) you get stuck ?
Or risk putting his reputation on the line if he doesn't ?
🙂

If it is a business in the first place.
Maybe he no longer wants to stay in "business" ?
Just be glad that people like him is still around.

Let me give you some insight.
To develop the final unit has taken me probably two years and up to 4 prototypes, say at an investment of maybe € 3000 - € 3500. When you bring out something like the autoranger, there's people that understand the functionality and the engineering behind it. They purchase the kit and build it successfully, with a rare case where someone needs some help, and if you are lucky you can recoup the investment. But it's also a lot of fun to work on something like that and the interaction with people that are interested.
Gradually, people read about it and the enthousiastic reports which tends to generate 'I want it too' reactions, without really having an insight in what it does, where/how it should be used, and the expertise and insight required to bring it to a successful end. That means that I have to set aside one or two hours a day just to support that phase. I don't have that time.
So there will not be a second batch.

Hey Jan,
There are those who understand, they get it. Some even know it.
Folks,
2 hours a day is an awful lot of time, that's focused work and he isn't getting paid for it. So hat's off to Jan for conceiving the project to start with, then actually producing a working product where there was none.

I have been asked about the case we used in post #841.
This is the link :

The front panel dimensions belongs to Jan.
You will need to ask him if he is willing to share.

The dimensions and locations of the holes and studs etc are for the specific autoranger boards and parts locations.
I don't see what value that has for other purposes.

Until you've done it, it's hard to appreciate the time that support can soak up. Never tried this with electronics, but I've written, documented, supported programming APIs and there's a ton of work involved, before, during and after.
The problem is that support is a draw, you feel obliged because it's your baby, your reputation. But every hour you spend on it is an hour you can't spend on something else more rewarding.
OTOH I'm relatively new to the whole DIYA thing and by the time I realised why I might need Jan's autoranger they weren't available. Frustrating, but that's life I'm afraid.
If someone happens to have an AutoRanger, but wants to put it in a case like mine, he would need the dimensions to machine the front panel.
The other way out is to measure from the sheet metal case provided by you.
That will of course be less accurate.

I bought the AR2 from someone recently and did few measurement.
The AR2’s input is shorted. Then routed to e1da scaler(fixed at 0dB gain) and then to ADCiso(6.7v). OP Amp used were opa1656.
0dB attenuation
-6dB attenuation
-18dB attenuation
-42dB attenuation
BTW, does anyone know if it is possible to make the autoranger target higher voltage level than 4v? E1da ADC can accept 10V input.

What use is pushing down noise if it raises distortion?
It's distortion measurement, isn't it?

I am looking to sell a version 1 AutoRanger. I ordered it originally as a kit then had Jan Diddan's associate build it. I have used it only a few times in the last few years as my ability to dig deeper into audio test has been hampered by some health issues.
Willing to sell it for $300 plus shipping.
Thanks.
