    First of all thank you for having prepared a section Elettroamici Theremino and apologize for not having contributed much in recent months. This is not fannullonite but just the opposite. We have so many new features in preparation that you can not finish some one. But now we're almost there, We prepared a lot of material, and in the coming weeks we will publish some really interesting articles.

    Here are the top:

    (1) NetModules e NetHAL
    These modules can be connected via WiFi, Network or Internet. But they are not like the IOT modules (Internet Of Things) which are located on the network, which they work through a server located somewhere and then communicate only if the internet works well. The NetModule not depend on anyone, except by the user who configures them and can also be used in the absence of the Internet. They are also easy to use as the Master modules. You should not plan their firmware, He takes care of the application NetHAL.

    (2) Arduino and ArduHAL Modules
    With the ArduHAL consider using an Arduino as an input output device for the PC. The application NetHAL, who acts as interpreter, and firmware that we have prepared for the Arduino allow you to use it with the same ease with which you use our Master. all the basic input output are ready, including DigIn with pullup, the ADC, i Pwm, i Servo, Counters and the period and frequency meters. To use them you configure them with NetHAL and seems to have a Theremino-Master Module.

    (3) Flicker Meter
    This will be the first article, if all goes well we publish today.
    Numerous studies have shown that flicker of light, although completely invisible, It may also cause headaches, eyestrain and nausea.
    To measure the flicker are very expensive commercial equipment (gives 700 a 3000 Euro). But we can easily build this meter, spending ten euros or less, using a master module and a tablet that we already have.
    Once you built this machine simply obtain a tablet or a notebook and you can take a scenic tour of his home and those of friends. It will be a surprise to find that a good half of the lamps, even the most unexpected, They have an average higher flicker and are to be deleted.

    The Flicker Meter is published:

    Today we begin the article that explains how to use an Arduino instead of a Master Module Theremino.

    I look forward to your articles, They are always very interesting


    You could write two lines in this forum what is the Theremino system without going to enter into your site “institutional”.
    A kind of presentation to become him also a EletroAmico.
    Health Marcello


    I try to write it in a nutshell, to do what is lacking specific questions.

    First of all
    The Theremino system is created by makers to other makers. We are all fans of electronics and we only care collaboration. So all open source, nothing inscriptions, no ads and zero profit.

    The system
    The Theremino system is a collection of ideas, schemes, applications and firmware, to connect the PC with the outside world. That light sensors, moving engines, control processes, etc…
    Unlike any other similar system, for example Arduino or Phidgets, you can experiment without writing a single line of code. So it is not necessary to improvise programmers and this makes the system suitable for education (Fast classroom experiments), but also for small or amateur scientific laboratories.

    The master module
    The main module is the “Master” that provides 12 In pin-out can be configured in many ways (always without programming).
    By using the maximum exchange rate Master (frequency of interaction between the PC and the sensors and actuators) It is around 800 exchanges per second, 900 at best. This is fast enough for most applications, also numerical control, such as cutters or 3D printers, but it is not enough for audio signals or radio.
    In any case, if you were using an Arduino (and soon we will publish everything you need to do) the Input Output operations with the PC would be even slower. The most that we have achieved is just 200 exchanges per second (with Nano) and even less with Arduino Uno.

    The application HAL
    The main application is the application HAL, that communicates with the Master via USB.
    The HAL helps “interpreting and translating” the input and output values ​​and allows you to configure the InOut Pin to adapt them to the sensors and actuators.
    One time “translated” the signals traveling on “Slot”, that I am a little’ of the mailboxes. Through the slot all system applications can exchange numerical information.

    Input Output alternativi
    The Theremino system is not the Master Module, but mostly a collection of software and firmware. There are some applications’ for all. And all can communicate well with each other without any hardware. Part of the communication with the outside of the PC can be done through your sound card, or a camera or, eg, a module for receiving radio waves.

    The future
    The same ease of use soon be available Wireless. Within a month we publish NetModule and NetHAL that will expand the system even to home automation and other fields, Now that would be difficult and awkward to implement. It is not about a “Internet of things”, with the dangers and difficulties of which there is much talk on the web, but a simplified system, totally reliable and completely safe, in line with the simplicity and minimalism that are the main features of the system Theremino.

    E’ since with a small group of enthusiasts were experimenting with amiga 500 e 2000 I thought that computers were to be used to function as the Theremin system instead…..

    therefore, to say Theremino: Finally!



    Major improvements to all HAL !!!

    - We have fixed dozens of small defects.
    - The list is updated more quickly, and not blinking, even if it is very long.
    - The list is more readable (eliminated the column "Dir")
    - The oscilloscope is improved.
    - Changes to the numerical values ​​are now faster, usando PageUp e PageDown
    - You can also use the arrows combining them with the SHIFT, CTRL ALT e

    Download the latest HAL 8.0, ArduHAL 2.0 the NetHAL 2.0 from the site Theremino (page: Downloads / Basic Applications)


    The application Theremino Automation has greatly improved!

    There are also Breakpoint, I Watches, the stepper operation, the instructions to go to full screen and the Select-Case. And finally there is also documentation, Read it to find out all the news.
