    Welcome!
    Sei capitato sul sito giusto, qui si studia, si progetta, si impara e ci si aiuta.

    E’ vero, lithium is scarce and pull it causes damage to the environment. But fortunately you can replace with graphene, which is graphite, then carbon (follow this link: Car batteries graphene).

    Carbon is abundant and the processes for its manufacture are simple and non-polluting. There are videos on YouTube of fans that show how to sift the graphite in the kitchen and build ultracapacitors and batteries. Of course, the features are not comparable to industrial realizations, but they work.

    The characteristics of the batteries graphene, constructed with the best techniques, They have a density of greater energy than lithium (over 500 Wh/kg contro i 200 Lithium) , They have a longer life and withstand higher temperatures without breaking.

    And finally, very important, no nonsense. The can already buy, They have the features promises and do not cost much. Here is a link where they found dozens of types: Batterie al graphs su hobby king

    Ciao, we did many experiments with this sensor, we just tried to verify operation with Theremino system. Furthermore, so far no one has written on the subject, so your searches are the most advanced and soon you'll be telling us what we can, and what can not be achieved by this sensor.

    Regarding the graphics in messages, I spoke with Amilcare that gave you your rights as an author, so now you can upload pictures and even write articles.

    For items you have available a complete editor and it should be easy enough to use it (at most ask me or Amilcare).

    Instead to insert images into posts on the forums you must do the following:

    1) Load the image using the menu Elettroamici (top left)
    2) In the menu choose “Media” and then “Add new”
    3) Then use CTRL-C (or other methods) to copy the link to the image.
    4) In the message, enter the “TAG” for the image with the link between.

    In practice, in this message, write: < i m g link-alla-immagine />
    (the spaces between “<" e le lettere "i", "m" e "g" non ci vogliono, qui ho dovuto aggiungerli per motivi tecnici)

    I agree on everything. With lithium batteries (which it is also poor) you do not get anything good.
    But perhaps there are possibilities with graphene:

    Apart from fixed expenses, various fees and other oddities of all kinds that we put in the bill, a kWh costs about 0.2 Euro.
    See for example who

    Multiplying 55 Kwh per 0.2 are 11 Euro.
    But I do not know what it means than a tank of gas, I live at zero kilometers, I sold the car and I do not do a full long time, and then with a full make you certainly more kilometers.

    You're right, but in this case the LEDs to be connected are indeed many.

    It would take at least 36 led, who knows how many more on the green carpet for the combinations. Plus one stampatone, a pile of multiplexer, buttons, display, drums, power supply…
    It would cost less than a tablet, It would also sounds and touch screen, may calculate wins and display…

    Ciao,
    I apologize for the delay, I thought I had triggered notifications and instead I have not arrived. Now and then I activated the next time I will answer right away.

    A guide that explains everything there is and it is not even possible to write it because it would be as long as the Bible Odiseea. So I will write here the first steps for those starting from scratch.

    The first advice is to start from simple things, not sure multimedia applications.

    So first of all you should get an idea of ​​what are the Slot, that is the center of communications thereminiche. Download it SlotViewer and starts to play. Lanciane two and verifies that moving the controls of the first to move the corresponding cursors on the second.

    Then maybe you download the SignalScope which it is a species of oscilloscope and moving the sliders of the SlotViewer see the values ​​of the slot that vary in flowing chart.

    you could also try to move the slot signals the Wave Generator and then write a few lines with Automation or take a command window with Buttons.

    But the center of it all are always the Slot, you absolutely need to understand how to use it otherwise you can not do anything else. And the only way to understand them is to try to communicate the applications.

    Then maybe you start watching the simplest applications This Page, maybe purchase a Master and a few LEDs on eBay or store-ino and try to turn them on.

    If you have no experience in e-mail to Leonardo store-ino and made to send a kit with some LEDs ready, and maybe even some servant who is always useful and interesting. And because you like music maybe you can also have them send the piezo sensors (sooner or later you are able to start the music applications, and if you do not succeed we'll help you do it).

    Do not rush to figure out everything at once, Theremino the system contains hundreds of different topics all. Some of them contain years of work and are quite complex. You can not addentarli all together.

    Continue only after you have made friends with the simple basics of the system and location is pretty much what you see on the page: http://www.theremino.com/applications

    However I am always available (engineering@theremino.com)
    or you may call me on skype (livio_enrico)
    and I could also solve you problems through TeamViewer.
