Not much fun in that!  Besides I already have access to a fully rebuilt one, as well as a dummy manual one I 3D printed and made up with wire.

Great idea since it could mean people could actually touch it and try it out.

I actually wish there was an Enigma in every school.. Kids would learn a lot from playing with it, since it touches many disciplines like maths, computing and circuits let alone history. Maybe optimistic thinking, but I wonder if there's any org or government body that could fund for such a prototype. 

We looked at getting my dummy enigma, pictured above, professionally 3D printed for schools to buy but it was too expensive really - IIRC, £130 or so and that wasn't with the wires or construction.

Schools who visit get to play with one and kids who visit with their parents are fascinated with it and the Bombe; they can even get a morse code message generated and then decrypt it on our Enigma.

Actually, come to think of it, there is/was a chap building them in Germany.  He would wait until he had around 10 orders and then make them.  Cost around €50,000 each!  

I would love to take my mutli-voice synthesizer ( Multi-Voice Synthesizer - Initial Design ) project and expand it into a fully functional product.  I am currently working on developing a MIDI interface for this project that will allow me to connect a MIDI keyboard and actively play notes and control setting within the synthesizer from knobs/sliders on the keyboard.

Unlimited - I would solve all the world's problems, but the details wouldn't fit into a reasonable paragraph so:

I would build a mostly self-sufficient, mostly automated, mostly solar-powered, homestead. Including large water based (hot and cold) energy storage systems and automated greenhouse. The man-cave part of it would be epic. And of course it would have a well equipped electronics lab. I like castles, so it might look a bit like a castle.

That actually brings up an interesting question - what would your dream man-cave (person-cave?) consist of? Because that speaks to what we really enjoy.

Unlimited budget? Part of me wants to says "a giant human-piloted robot", but I know there's many other projects that would be a lot more useful to humankind that would still be extremely fun to work on. HOWEVER, today I'm not fighting the thought, so a giant human-piloted robot is my answer :P 

Unlimited budget? Technically speaking there is no such thing as unlimited budget, there is always a limit. But let's say it is very high budget in some billions of pounds, then I would start building my own spacecraft and use components sourced from Element14 and go to mars and return back home.!!

But if there is budget of lets say 5000 pounds, I will build some PCBs with different chips that I like. ! more specifically, I will build something with RGB LEDs.!

For me it would be model railway. Typical issues are high cost, and lack of space and free time. Unlimited budget obviously solves even space problem because decently sized one or two buildings also fit the budget 

Is Farnell interested in sponsoring?

If not, perhaps consider a 'T Gauge' model railway.

Could be tempted by something like this: Glenfinnan Viaduct Picture Frame Diorama

Better still if there were multiple picture frames with a number of trains passing between them along a dado/picture rail, perhaps with one as an engine shed to display the available rolling stock.
