Steampunk sucks, but I respect the drive people have to put so much effort into the things they make even it disgusts me, and it's always nice when somebody makes something steampunk-y that I don't reflexively hate (like this).
It's funny, I almost replied to this with a joke about how I agree but most Steampunk stuff doesn't even fulfill that, it's just an arduino board in a box with some cogs.
And then I watched the video.
And it's an Arduino in a box with some cogs, more or less.
This is like getting a wide mouth jar and putting a toy ship in it and then saying you made a ship in a bottle.
