Re: A Peaceful FairTrade Thread

jamesh - I think you're right. So let's look at what other components can be sourced sustainably, because there's no Fairtrade silicon supply right now. The Fairphone documentation talks about gold, tin, tantalum, and tungsten. Which of those minerals are used in which components in the Raspberry Pi?

Re: A Peaceful FairTrade Thread

hippy - Good point about percentage prices! I chose that because of variability in current prices: currency and model A/B affect it. I disagree about discussing the merits/problems of FairTrade on this thread - let's leave that discussion to the FairTrade forums. jamesh - We'll see what the poll say...

Basically I'm interested in gathering all the information related to customer demand, price elasticity, components required, and suppliers into one place. Maybe even the Wiki could be appropriate, as this is an information-gathering exerc...

My last week at work has been really rather busy, but I finally had time to spend on the Guzunty clone project this morning!

We? How many people are in the Guzunty team? I might have a few friends from Lancaster University interested in this project. How realistic would it be to make a PCB breakout for the 672 pins on the Virtex? Sure, the size is large, but the flexibility would be so appealing. The BGAs aren't terribly ...
