31  General Category / General Discussion / Re: Arduino Due (released Oct 22, 2012) Compatibility on: October 04, 2012, 11:37:01 am
I just don't get the Due concept. I just feel I must be missing something obvious. Someone please explain it to me.

Surely, if I need more processor, then its because I'm doing something fundamentally unsuited to an operating system-less device like the Arduino. I.e., image processing, DSP, MP3 playing etc. If I need an OS I'd have Linux on a Raspberry Pi.

Arduino is a device for electronic hobbyists. 16 million things a second is faster than I've ever needed an Arduino to perform.

For what its worth, my experiences of using the Leonardo.

Come mai vuoi imparare l'italiano? Vieni a vivere in Italia?

Oggi anno ho visitato l'Italia (vacanza).

In 5 anni, quando tutti i bambini ha lasciato a casa, vogliamo vivere in Italia per alcuni anni.

Scrivo ovunque - occupazione mobile! smiley

5 anni per imparare l'italianto senza Google Translate smiley-wink

@Madwriter

Cambio posto?

Si, certamente! 10C, pioggia, vento!

Vorrei estudiando Italiano da solo, pero capisco electronica perché scrivo libri su elettronica.

Ho 3 Elektor inglese. Chiunque cambio per 3 riviste en italiano?
36  International / Generale / Re: Riviste di elettronica in italiano on: October 02, 2012, 07:53:20 am
Grazie mille,
Particolarmente per le correzioni. smiley
Eccellente - più riviste in Italia che uk.
37  International / Generale / Riviste di elettronica in italiano on: October 02, 2012, 06:53:53 am
Sto studiare l'italiano. Ci sono riviste di elettronica in italiano che ho potuto leggere.
Sia on-line o su carta.
Raccomandazioni per favore.

Haven't you ever tried a j-turn in your car. Full speed reverse, full lock of the wheel and jam into drive. Totally normal! ;-)

Ha - no, not tried that.

But then thats fine because engine and momentum are in agreement by the time you lift your foot off the clutch.
39  Using Arduino / General Electronics / Re: Solar power, little help on: August 28, 2012, 03:30:18 pm
Ah, sorry so solar charges battery, then battery charges other things. The battery bank expects 1A at 5V, if its charging a LiPo, then it probably does expect to have 1A available for its smart charging.

You could use a good old 12V lead acid battery charges from the solar and then a 7805 or higher power providing the 5V out to the camera etc.



40  Using Arduino / General Electronics / Re: Solar power, little help on: August 28, 2012, 03:09:12 pm
A 7805  can cope with 35V input. Presumably you got 5V out with no load. If the camera expects to be able to draw 2A, (which seems a lot) then the solar panel isn't going to supply more than 200mA, so the output voltage will drop.

is it fundamentally bad to send a motor in full reverse from full forward

Ouch, Yes. I don't think you would do that to the gearbox of your car? Full speed forwards then slam it into reverse!

Stop it, then reverse it. The capacitor is not going to store a significant amount of energy in comparison to the kinetic energy of a 150W motor!

You could just buy some powered USB speakers. Saves some soldering.
43  Topics / Education and Teaching / Re: Good Books To Learn About Arduinos and Programming on: August 22, 2012, 07:40:31 am
You don't need a book - but books are distilled knowledge and often speed up the learning process smiley-wink

I have to register an interest here - I am about to recommend my own book, but it has had a lot of good reviews when it comes to getting newcomers to Arduino Programming on the right track.

44  Using Arduino / Project Guidance / Re: Motorized Blinds on: August 12, 2012, 03:12:17 pm
If the blinds are heavy, then its not going to be easy. A fairly powerful gearmotor winding the cord around a cylinder might work okay.

Its the kind of project where you will probably need to try a few things out - do some experimenting.

If there is a way to use a counterweight against the weight of the blinds, that will considerably reduce the power of gearmotor required.

I meant to also add, here are some of the things I have been doing.

More experiments than projects. http://www.doctormonk.com/search/label/raspberry%20pi

Si.
