Of all the things that I could possibly think of "making a DYI version of would be fun", a machine that has ~0.5-1.5 liters of boiling water at significant pressures is on the very very very end. Hats off to you if you feel comfortable with that, but I wouldn't want to be in the same _room_ as that thing.

Water under significant pressure is not really that big of a deal. It is largely incompressible, so if there is a leak, it just, well, leaks. Sure, it can spray, but even then I've been hit with hot water from my espresso machine and while it was temporarily painful it didn't burn me. Air or steam, on the other hand, is a different story - steam boilers obviously can fail explosively. The pictures of the machine makes it look like it has a steam wand but I think that's just because he salvaged an old boiler - I don't think he's actually bringing up the temperature in the boiler high enough to make it a steam boiler.
