Self Replicating Machines. Sounds like something from the future but some have been with us for a while.
The latest, an Open Source version, is the RepRap. I think I will build one when I get some spare pennies.
Although it is a long way away from a Star Trek type replicator I’m sure it would be useful in any mad scientists workshop and significantly cheaper than the others I’ve seen so far. I wonder what some bright spark will make with it? Need to keep my eye on the Open Source builds.
Now if only it could make ammunition.
