Your mini projects

[zero cool]

Feel free to post your mini projects in this thread. It can be something as simple as modding another battery into something, taping together some sticks, or building something small with properly designed PCBs and the whole lot.

I'll start with me replacing the belt in my Sony Sports Walkman (WM-FS473) from 1998. I forgot to take pics during the swap, but eh, whatever. I couldn't for the life of me find a belt that was specced to work with this player. But I remembered https://fixyouraudio.com/ had walkman belts, buuut of course not for my player. So I got in contact with the guy behind the site. An awesome and helpful dude. We sussed out that I needed a 70mm 0.6mm square belt. I got the new belt today, installed it, and holy fuck, what a difference! It's insane how big of a difference such a small thing can make. And also impressive how bad and off music can sound with such little variation.
Anyways, here's an after-shot.

As it happens todays mini project is also related to the thing above. The plug on those SONY headphones is straight, which makes it incredibly awkward to put the walkman in a jacket pocket. And instead of replacing the plug with an angled one I picked up some 90 degree adapters from Amazon. This paired with an adhesive rubber foot as a support spacer made a decent angled headphone jack on the side of the player.
