Hai ragione, ho usato una parola ingannevole. In effetti per noi “makers” studiare non è quella barba che ti impongono a scuola (e che ti fa passare per sempre il sano istinto allo studio e alla curiosità), ma piuttosto “imparare sperimentando con gioia e piacere”. E, naturally, per mantenere vivo questo “piacere della scoperta” è necessario che ogni “studio” avvenga al momento giusto. E il momento giusto è quando l’istinto ti fa venire la curiosità e non quando la scuola te lo impone a forza.
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…
