I just built something I had to get right on the first try because messing it up would be more than a little dangerous. Endless fitting and testing and re-thinking before committing to building it. A little cheating was involved, I built a 1/17th scale test setup to ensure that all the electrical bits would work.

Does it?!

Yes, it works. Test rides three days ago, first real trip yesterday, 65 km there and back on a single charge. Write-up one of these days, have to collect all the material.

Electric bike?

2KWh+ battery pack in a very weird shape.

Excellent.

I've never actually been scared of stuff I built before, that's a first (and that doesn't mean that I shouldn't have been scared with other projects, just that I wasn't either because I wasn't aware they were dangerous or simply too absorbed to stop and think about it).

Wait what did you build?

Very large battery pack for an e-bike. I'll do a write-up soon, still have to collect all the pictures and the text. It works incredibly well but it took way too long to make.
