    IF YOU CAN’ IT IS USEFUL TO ADD THAT EVEN CLOSING THE FAILED CNC AS SOON AS OPENED RE-OPENING THIS AND’ STILL FAILED TO RESET EVERYTHING I HAVE TO DISCONNECT USB AND TURN THE CNC OFF

    REGARDS

    GOOD MORNING
    I SOLVED USING CNC V4.9 AND HAL V7.0
    THAT I HAD INSTALLED ON AN OLD PC WITH WINDOWS 7
    I HAVE TRANSFERRED THE RELEVANT FOLDERS TO THE PC WITH WINDOWS 10 AND IT WORKS
    AS ON THE OLD PC I HAD BOTH VERSIONS EVIDENTLY I WAS USING THE OLD ( And’ A LITTLE’ THAT I DID NOT USE THIS CNC AND MAYBE I DID NOT REMEMBER THE PROBLEM ).PROBABLY I DON'T KNOW SOMETHING IN THE SW ESCAPES.
    GREETINGS AND THANKS AGAIN

    Good morning! houn theremino and I just downloaded the program, I admit that I find myself for a moment confused by its configuration, there is someone who could help me? Who can I contact?

    • Livio says:

      Write your questions here.
      Or write to me at engineering at theremino dot com
      So then maybe I could also help you by phone, or Skype or AnyDesk.

      • Luigi says:

        E-mail sent!
        Many thanks in advance!

        • Livio says:

          With Skype's screen sharing, getting it to work was pretty easy.

          For those with similar problems, remember to use “Load config.”, just to start making some sounds and then read the instruction file.

    Good evening. I would need information. I have an ESP32 IOTmodule – Picokit V4 which I use to read environmental sensors. The firmware version is 182-1. I feed it with a powerbank to 5 Yes 5000 mAh of the type for mobile phones. The powerbank allows (from what the manufacturer says) charging a mobile phone and recharging it simultaneously. Everything works very well. The only problem I encounter is when charging the powerbank or better, when I unplug the mains charger when the powerbank has recharged. In that moment, what IotHAL (ver. 1.4) it disconnects from the IOTmodule and the writing in red appears (sometimes even in blue) that the module has lost its configuration. I have the impression that, with the disconnection of the mains charger, the powerbanck will restart. But I just need to click on “Recognize” of the IotHAL to restart everything normally. Do you have any idea what could cause the detachment between iotmodule and IotHAL? Some software or hardware adjustments are needed? Thank you

    • Livio says:

      When the battery charger is disconnected, the PowerBank you are using makes internal switches and then interrupts for an instant the 5 output volts.

      Not all power banks do this “defect”, you might see if you find one that doesn't cut the output voltage.

      I just tried with one of those with two batteries and with the switch on one side that turns on an LED and behaves even worse than yours. For as long as it receives the 5 charging volt sends the ESP32 a voltage of only 3.5 volts, which of course is not enough and the ESP32 disconnects.

      I also tried one of the rectangular ones, from a single battery, flashing red and blue while charging, and he also stops powering while charging.

      If you don't find any that keep the communication active and if this functionality is really important in your case then you could:
      – Use any PowerBank (so also your current one)
      – Derive two red and black wires directly from the + and – of the batteries (get them out of a hole but be careful that these two wires never touch because the batteries could suffer a lot, and the wires get hot and even catch fire) (eventually it would be good to add a fuse from 2 amps in series with the positive wire and near the batteries)
      – Connect the two wires to a step-up power supply that produces a 5 stable volt starting from 3.7…4.2 battery volts.

      You can easily find suitable step-ups on eBay, for example this:
      https://www.ebay.it/sch/i.html?_from=R40&_nkw=174466904903

      However IotHAL should (If possible) reconnect by yourself. I just tried the version 1.4 and reconnects, if yours doesn't maybe you are using an older version. Or perhaps the power supply of the ESP32 is missing for too short a time or it does not come back with enough voltage and the ESP32 does not reset well or cannot reconnect to the network.

      After the IotHAL has reconnected the writing remains “The IotModule has lost the configuration” which is used to know that in some past moment the configuration has been lost. But the FPS box should indicate a communication frequency (not zero) and it should no longer be with the red background. And this indicates that everything is fully operational again.

      Pay attention to the cables that are used to power the ESP32 !!!

      Just today trying the Power Banks I discovered that the cables count a lot.
      The tension starting from the PowerBank was about 5 volts
      – With round black cable, one meter long, the voltage on the ESP32 was 4.74 V
      – With flat white cable, long 30 cm, the voltage on the ESP32 was 4.2 .. 4.4 V

      I expected the short cable to go better but no,
      it goes so badly that the ESP32 occasionally disconnects.

      After an hour the PowerBank was up a little’ downloaded and gave alone 4.8 V
      The voltage with the short lead was lowered to approx 4 volts,
      and of course the ESP32 disconnected and just didn't work anymore.

      So I tried to change the cable and put the black one.
      The voltage on the ESP32 has risen to 4.6 V
      And now it's been hours !

      So before blaming PowerBanks or short-lasting batteries.
      Look for the right cables!!!

    Good evening,

    I am a chemist and I recently approached the world of Theremino. In particular, I'm interested in gamma spectrometry and find it really fascinating, also in didactic terms, the possibility of combining MCA with THEREMIN (in configuration “radioactivity”) to hear the “music” of radioactive isotopes. I did several tests with a NaI detector(TL) purchased on the net and everything works very well, but I was wondering what settings to use on THEREMIN to differentiate as much as possible the music of one isotope from that of another.
    I would like to point out that my skills are very few in the field of audio. Anyway, i noticed that in the configuration “radioactivity” the system actually uses only a few of the virtual music keys: accordingly, two isotopes can be distinguished easily only if they have very distant peaks (for example Cs-137 and Am-241, with main peaks respectively a 662 and 59 Kev), while, for example,, it becomes difficult to appreciate the difference between an Am-241 source and the Th-234 of a Fiestaware turntable (peak at 92 Kev). I tried to tweak a bit, for example by changing the chords you can improve something, but not by much. So I ask if you have any useful information to give me and I thank you in any case.

    • Livio says:

      I'm sorry but we haven't done much more than what is in the configuration “Radioactivity”. If you managed to make it sound and even improve it a little’ you probably know even more now than we do.

      Probably you can't do that much with audio, and you will never get the resolution obtainable by looking at a graph.

      Maybe you could make an application in Theremino_Automation language, or even with VbNet, which could read the output slots of the MCA doing complex reasoning, linearize the data or make it logarithmic, select the notes to use, use different notes for each isotope… etc… And at the end write in other Slots the processed values ​​that would make the Theremin application sound.

      But the question is: it would be worth it? At bottom “to listen” it's just a curiosity. While “to look” it works much better. So I wouldn't waste too much time on it, I would use it as it is now and the real analyzes I would do with the graphs.

      • Gabriel says:

        Hello Livio,

        thanks for your prompt reply. I agree with you: music is nothing more than a curiosity and what really matters are the graphs of the spectra! My interest in the audio aspect arises mainly to make teaching radioactivity more interesting for my students.
        Very interesting what you say about the possibility of creating an application in Theremino_Automation, I will try to think about it and eventually I will come back to disturb you!
        Thank you for all the wonderful work you do for the benefit of so many enthusiasts!!!

        • Livio says:

          Thanks to you for the compliments. And ask whenever you need it, It is not a disorder. And thanks for writing here on the blog instead of sending us private emails. Each post here in the blog can be of help to everyone.

          And best wishes for your lessons “radioactive”. which will surely provoke a special interest in the boys, always attracted by dangers and forbidden things. If you haven't already, I recommend that you buy kilos of potash and pumice stone. They are completely free for sale and you can also eat them. But when you have some kilos, they produce quite a lot’ of radioactivity.
