This isn't a very intense ~DIY project, I'd categorize as ~repurpose if such a territory existed, but it tracks a bit.

When we moved last year, we struggled with where to put all the electronics. We live in a tiny place and the fiber outlet coincides with the only place for a TV (and wife didn't want to ditch the TV) so we were obligated to put many gizmos in one place. All the media consoles I found were huge, sized like it's still the year 2000 when TVs required several cubic feet of equipment. So I started hunting for something I could repurpose, anything that:

After lots of searching for small cabinets, and I mean lots (I tend to get super obsessed when problems are aesthetic and particular¹), I stumbled across a bunch of wardrobes made for large 10+ inch play dolls. Eventually I found one that was the perfect size, apparently handmade and painted, probably 30+ years old, and well taken care of. I'm swapping my raspi out for a Start9 Server today and I thought I'd share.

You can see the little dowel for hanging tiny fake person clothes in front of the embarrassing tangle of cables.

It ended up working better than I'd hoped. The little shelves are just wide enough to fit mini computers. I was able to take the backing off so I could access the power and fiber outlets on the rear wall behind it and run other cables in and out. It also has a drawer on the bottom for excess cables and the top is the perfect shelf for the Wifi router and remotes.

I love repurposing. It's a lot of what engineers strive to do well.

Have you memorably repurposed anything?
