>I wonder what that would take. What the smallest amount of shipments and time would be. Would guess that electronics would be one of the last things you'd learn to make yourself. If I recall correctly the number quoted from E. Musk on an early Mars colonization presentation was 2 cargo ships per full colonist ship. But that's only for being water/air/food/energy self-sustained. The assumption is that large shipments of high-tech products will continue for a while. Maybe something like solar panels/basic air turbines can be produced on the spot provided with either the raw material or mining equipment. The same probably goes at least for simple electronics( like e.g. various sensors for monitoring the colony), lots of appliances can be made in a crude way( think stoves, furnaces, maybe fridges?).
