The newest RepRap, RepRap Version II “Mendel”, will be released very shortly. Here is a video of it working. It is both bigger and smaller than RepRap Version I “Darwin”: it can make bigger things, but the machine itself is physically much smaller.
I’d like to reassure everyone that Stormdrane is not paying me under the table. But public denials cost an extra $50 and he won’t pony up the dough. So you’re just gonna have to wonder.

The tea water was still hot on the stove, so it was ready to provide some double boiler action. I poured some hot water into a steel pan, put the ferric chloride into the jar and dropped in the first board.
