Re: Neo900 - finally a successor of N900
Well, they're just working fundamentally different. In short, you would destroy the LED with the very high current needed for such a short pulse (100x shorter flash at same integral intensity means...

No, they values quoted on the Wikipedia page are for conventional xenon/gas discharge flashes. LED flashes have a much longer duration - try photographing a moving subject, you will see that they're...

There's a nice instruction on how making a spectrometer out of cardbox and a DVD-R as a diffraction grating:

Re: Neo900 - finally a successor of N900

There's also the possibility to use some kind of audio compression , though it makes things both on the phone side and the other half more complicated.

Re: SolarJolla
I would say yes, 2h in direct summer sunlight should be enough to charge 20% with such a panel (2Wh minus losses). The pitfall is that you have to direct it at least roughly to the sun's direction,...

Re: SolarJolla
The surface area is included in the rating of your panel. An 1Wp-panel gives 1W at 1kW/m2 sun intensity, this can be reached by a bigger panel with low efficiency or a smaller one with higher \eta....

Great project, but be careful with the panel's power rating. It is given for an incident light intensity of 1000W/m2, which is reached on a sunny day in central Europe around noon, with the panel...
