This is, without a doubt, the coolest Instructable I have seen in a long time. User Urant takes us through the ins and outs of building a working espresso maker with a built in alcohol stove out of relatively inexpensive parts. The build itself is intricate, but not overly complicated and can be accomplished with some copper plumbing parts, a soldering iron, and a syringe – for a build cost of approximately $30. We are assuming he/she used a non-toxic soldering solution (heavy metals and coffee don’t mix).
The end result, a tiny espresso maker with a built-in heat source that can fit into a pocket. It looks great, but it is hard to judge as there is no video of Urant’s construction in action.
