Hi, I (Rob) and my son (Nathan, 12) are considering building a RepRap. To be precise, a Mendel. We are both pretty good at cutting code. Nathan has some electronics experience and training (including a course at Box Hill Tafe). And we have a little Arduino experience. After long hours web-surfing we realise that we need to talk to some people who have actually done it. We plan to attend the nby robblair - Australia, Melbourne RUG
