I've just been doing some power tests with a Pi Zero...

Re: waveshare 7" touchscreen

Yep, same problem here too. For reference, this is the screen I have and it's PCB rev. 2.1: http://www.waveshare.com/wiki/7inch_HDMI_LCD_(C). Works fine when using the latest Raspbian "out of the box", but after an apt-get upgrade it stops working. No doubt there's a fix out there somewhere, I can s...

Remember that Pi zero isn't manufactured in external factories so it takes time to produce them. I'm not sure I understand what you're trying to say here... AFAIK neither Raspberry Pi Trading nor the Raspberry Pi Foundation have their own in-house PCB assembly facilities. It's contracted out, which...

True, you'll get a much higher watt/hour rating out of 8x1.2v@2000mAh cells than you would with 2x1.2v@2000mAh cells :).

Wouldn't @OP be better off with a boost converter, to cut down on the number of cells required? The boost converter IC in the Adafruit Powerboost 1000/500 (Texas Instruments TPS61030 http://www.ti.com/product/TPS61030/datasheet) can supply 5v with an input as low as 1.8v at pretty good efficiency le...

I'd say the problems OP has do not only come from the size of the dataset ... but also from the choice of "programming language" ? ghans Certainly the wrong tools, I'd agree with that.

+1 Excel is not meant for this type of 'big-data' processing.

Pi3's are great but they aren't the most scala...

If the calculation is already slow on an i7 w/8GB RAM then a Pi cluster is not going to help you at all. More RAM might possibly help, but probably not by much. Of course as a pure educational exercise it might be worth looking into, but I wouldn't rely on it to get work done in a timely fashion. Th...
