    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!

          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

      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,

    sono un chimico e mi sono avvicinato da poco al mondo di Theremino. In particular, mi interessa la spettrometria gamma e trovo veramente affascinante, anche in termini didattici, la possibilità di combinare MCA con THEREMIN (in configurazione “radioactivity”) per ascoltare lamusicadegli isotopi radioattivi. Ho fatto diverse prove con un rivelatore NaI(TL) acquistato in rete e il tutto funziona molto bene, ma mi chiedevo quali impostazioni utilizzare su THEREMIN per differenziare il più possibile la musica di un isotopo da quella di un altro.
    Faccio presente che in materia di audio le mie competenze sono ben poche. Comunque sia, ho notato che nella configurazione “radioactivity” il sistema utilizza di fatto solo pochi dei tasti musicali virtuali: accordingly, due isotopi riescono a distinguersi facilmente solo se hanno picchi ben distanti (ad esempio Cs-137 e Am-241, con picchi principali rispettivamente a 662 and 59 Kev), mentre, for example,, diventa arduo apprezzare la differenza fra una sorgente di Am-241 e il Th-234 di un piatto Fiestaware (picco a 92 Kev). Ho provato a smanettare un po’, per esempio cambiando gli accordi qualcosa si riesce a migliorare, ma non di molto. Chiedo quindi se avete qualche indicazione utile da darmi e vi ringrazio in ogni caso.

      Mi spiace ma non abbiamo fatto molto di più di quello che c’è nella configurazione “Radioactivity”. Se sei riuscito a farla suonare e anche a migliorarla un poprobabilmente ora ne sai anche più di noi.

      Probabilmente con l’audio più di tanto non si può fare, e non potrai mai avere la risoluzione ottenibile guardando un grafico.

      Forse si potrebbe fare una applicazione nel linguaggio Theremino_Automation, o addirittura con VbNet, la quale potrebbe leggere gli Slot di uscita dello MCA fare ragionamenti complessi, linearizzare i dati o renderli logaritmici, selezionare le note da usare, usare note diverse per ogni isotopo… etc… E alla fine scrivere in altri Slot i valori processati che farebbero suonare la applicazione Theremin.

      Ma la domanda è: ne varrebbe la pena? In fondoascoltareè solo una curiosità. While “guardarefunziona molto meglio. Per cui non ci perderei troppo tempo, lo utilizzerei come è adesso e le analisi vere le farei con i grafici.
