I've received my Analog Discovery, and I'm very eager to construct the impedance analyzer and start playing with it. Has the schematic for the plug-in board been published anywhere? The video on the plug-in board should contain enough information to build it, but constructing it from a known correct schematic is less prone to errors.

I recommend you wait for the kit, likely it will be cheaper than what you'd pay gathering the parts by yourself, even if it's slightly more, consider that you'd be contributing to the project.

I've already ordered parts for the first batch, first come first serve once I have everything ready.

Excellent, looking forward to it. I would of course also still buy your kit in any case, that's the least I can do.

On a more technical note, if more supply current was available for the plug in board, would it be possible to improve the performance when using longer test leads? If so, would it be difficult to add an option in the software for arbitrary input and output scaling, to allow the seamless use of output buffers and more stages of input amplification?

Hi Jaxbird,

Any update on this project? I am very interested in building one.

Thanks!

this project is so awesome
isnt it possible then to measure the Er of circuit board?

ruairi · « **Reply #230 on:** November 21, 2016, 06:53:10 am »

Agreed, I'm hoping Jax still has this on the back burner.

steverino · « **Reply #231 on:** November 21, 2016, 06:44:14 pm »

Jaxbird's profile indicates he hasn't been active on the forum since July.

ruairi · « **Reply #232 on:** November 22, 2016, 03:52:43 am »

No updates to his website either. Life gets in the way. I hope he gets back to it, it seems like a fun project.

ruairi · « **Reply #233 on:** January 09, 2017, 04:40:05 am »

Hi all,

Jaxbird posted a new Impedance Analyzer video on Youtube!

Fingers crossed that the project will be released soon.

Cheers,
Ruairi

Hi,
I just found this thread.
This project looks amazing and I'm very excited.
I would definitely buy one kit if/when it becomes available.

Cheers,
groggen

Unfortunately this has been untended for a while. I tried PM Jax to no avail. I hope he gets back to it!

bitseeker · « **Reply #236 on:** March 27, 2017, 09:43:57 pm »

I hope so too.

Jake, if you're still out there, I just got an AD2 and look forward to trying one of the kits. Meanwhile, I'll check out your audio analyzer suite. Cool stuff.

casinada · « **Reply #237 on:** March 28, 2017, 05:48:49 am »

He has a website:
http://www.thestuffmade.com/
May be he'll reply overthere

He seems to be replying to people, at least for the audio analyzer project.

Here is something similar??

At diyAudio, Frex reports here

Just some pictures of my small test fixture to use the Analog Discovery as Impedance Analyzer with the cool software of TheStuffMade.
It's only connectors and one resistor..Difficult to do simpler than that !

He's using Analog Discover Legacy (AD).

While my AD2 works nicely with the WaveForms network analyzer, AD2 isn't recognised using Impedance Analyzer with the same elements attached (100R/10R).
Audio Analyser sees the AD2 (Not so sure whether it works as it is supposed to do - no time to check, yet).

Anyone being able to use Impedance Analyzer with AD2 instead of AD?

look forward to trying one of the kits.

Me too ,-)
Don't know how to apply for a kit or a board, though.

Hello, I would also be very interested in getting the PCB and components as a kit. However, I have just found out about this thread, and it looks like the project is having no activity since beginning of 2017. I look forward to any news, as it looks quite an interesting development!.

I'm not sure if there are people who are aware that digilent have released an update to their analogue discovery waveforms 215 that now includes an impedance analysis.

Here's a digilent blog entry regarding the updated waveform software, including the impedance stuff.

bitseeker · « **Reply #242 on:** December 01, 2017, 09:48:35 pm »

Yep, they added that and the ability to use scripting with the spectrum analyzer. It's a nifty little device.

rx8pilot · « **Reply #243 on:** January 06, 2018, 05:48:05 pm »

The AD2 is quite a bang for the buck....I want one now. The impedance functionality is an excellent upgrade since the project that started this thread seems to be abandoned.

Just to nekro my old thread and add an ending.

The whole project with all details can be downloaded here:

And some basic details here:

I understand a lot of people say: hey, the Waveforms software does this now?, why would I even need this anymore?

True, the official software did add impedance measurements after I showed my work, however they didn't implement any calibration, this makes their software absolutely useless. Not kidding, it cannot be relied on without calibration.

Welcome back jaxbird, I thought we had lost you!

jaxbird · « **Reply #247 on:** June 21, 2019, 08:40:01 pm »

Thanks

You did lose me for a while, I had to do some regrouping and make some really hard choices on what really matters in life.

But yes, I'm both alive and back.. thanks..

bitseeker · « **Reply #248 on:** June 21, 2019, 09:14:34 pm »

I second that. Great to have you back!

peteb2 · « **Reply #249 on:** July 17, 2019, 08:31:11 pm »

Of interest, has anyone who is following jaxbird's fantastic work on measuring impedance, have you managed to have his greatly appreciated S/W for download from via his Dropbox link run with an AD2? I'm finding with the program running under Win7 OS displaying the GUi & plugging in the USB to my AD2 the audible announcement occurs (the driver is running) but then instantly there's a flash of status text for USB voltages etc on the GUi and the message "Device not available" returns. The AD2 onboard LED continues to flash.

If i run the AudioAnalyzer however things are absolutely fine!

I guess in a round about way, what i'm asking is has anyone managed to make 1.3.0.43 work with their AD2?
