These are not equal to Dialgizmo, they may be better or worse, but they are polarity sensitive according the add. They also lack the possibility to choose type of dial, and some functions i do not remember, but this is an option on the Dialgizmo.

I used the Dialor 1.2  in a project, and yhat worked great, no polarity issues, but it was more of a rotatone unit:  https://goo.gl/dAJ7T5

In that price range, I found 6 sellers with all prices about $30 including shipping and all but selling the Dialor2.0 and one selling the Dialor2.

They all look alike and vary in price a few bucks. If there is another converter that is different from this style, please post the links so we can compare. The are others but not in the price range you stated. The others that I found are in the $35 to $60 range with shipping.

The following all look alike.

I elude to the post 2 uip from this quoted post of your own here. When you buy from China you should never assume 2 units are the same as there are nmany variations on the same product and most are "no name"

edit, OOPS thats YOUR OWN POST!

By the way those of you who are concerned about polarity i am sure you could stuff a bridge rectifier into that package, as a polarity guard.

Ralph Meyer at TCI did a really good write up on the differences and shortcomings of many of the converters out there.
Read it here
 

That being said, I slapped together my own Internal converter utilizing the code from Boris Cherkasskiy's work...




However this new(er) opensource external converter is probably a better way to go for the Do it Yourselfer.
As a side note, This newer iteration addresses several of the BIG issues that previous converters failed to deal with.

Hackaday did a write up on it a while back. All links to the resources are there as well.

https://hackaday.io/project/28557-pulse-to-tone-converter

Since the Firmware source and Gerber files are available you can whip up as many as you want and make any changed to it that you like.

BTW, I ultimately removed the converter from my phone and have installed a 616.. honestly it seems that the Panasonic machine is the only way to go!

Thanks for bringing that to our attention, Sigmaz.

Oddly, I've recently been addressing some of the problems with the original Boris Cherkasskiy/Arnie Weber converter.  So far I'm pleased with the results but the real test is actual use over an extended period.
