Dave went to Agbogbloshie in Ghana. A big dumping place where a lot of old electronics from the west end up. Remember your old phone, DVD player, remote controller? They're likely to be there by now. Or somewhere else in Africa or some poor nation not able to stop the flood of incoming e-waste. People skilfully and resourcefully use this stuff to hack and build new things in ingenious ways. Definitely a fascinating place full of nice people.
