I repair almost everything and just love to tinker with gadgets and tech in general… repurpose/reuse old things, make beter versions of them, etc.
Simple example, all of my old audio equipment now has Bluetooth, an MP3 player, an aux input, a USB port (for MP3 playback) and an SD card reader (also for MP3 playback)… oh and let’s not forget the FM tuner that comes bundled with those thingies 😂. Don’t use it, but still, it is a nice option to have at your disposal 😉.
