Ask HN: Most interesting tech you built for just yourself?

Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

My MIL is 93, and the only tech she can really deal with is turning on the radio and TV and changing channels.

She is fond of music from old classics (from the 60's and earlier), so I hooked up a Raspberry PI with an FM transmitter and created her own private radio station. She tells me what songs she likes and I create different playlists that get broadcast on her station. It preserves the surprise element of radio, and there is nothing in there she doesn't like.

The tiny FM transmitter is surprisingly powerful. Her neighbours (of similar vintage) are very happy too, so their requests have also started coming in :)

EDIT: I wanted to add that I am the UI ... she doesn't get to choose the playlist. To make my life easier, I just created different playlists for different times of the day ... calm/spiritual/slower numbers in the early and late hours, peppy during the late morning and evening etc.

Very cool. Do you connect it to Spotify or to an MP3 collection?

From my MP3 collection. I buy the songs or albums she likes and broadcast them. For some that are not on sale anywhere, I scrape them off youtube, but usually send a note to that channel for original sources where I can pay for it.

Cool! I asked because there are many niche playlists on Spotify you can find for oldies, for example some very specific for the 60s, 50s, 40s, etc. Perhaps it could help her discover similar, but new, music.
