Re: A supercomputer for £100

<t>I agree with DeliciousRaspberryCake. This would be an excellent approach to teaching distributed computing on a small scale with small costs, but it would not do well at all to use any current SoC for a supercomputer. For that, we tend to stick with high-end x86 chips, or Itaniums, Sparcs, or Pow...

Re: Solar panel tracking

<t>I wouldn't worry too much about the first point. The second, however, is interesting.<br/> <br/> What if the optimum orientation, when there is cloud cover, is not directly at the sun? It is clear that a solar panel can still get significant power by pointing generally upwards, thanks to refracti...

Re: Searching for Meteorites with the Raspberry Pi

<t>How's your budget?<br/> <br/> I've seen setups where a decent webcam is connected (though an intermediary device) to a wifi setup, so that the camera's picture is shown elsewhere in real-time.<br/> <br/> What if you did something like this:<br/> <br/> Each camera -> one R-Pi:<br/> <br/> R-pi will...

Re: Solar panel tracking

<t>In my opinion, this is not the optimal solution. I don't know how it's done in industry, but frankly I wouldn't use time/date calculations. I would instead use real-time power data. That is, every so often, change the inclination of the panel until power obtained is maximum. The reason I would do...

<t>Moor -- quantum mechanics, transistors, digital logic design, and computer architecture. Them's your building blocks if you're starting from scratch.
