It could be anything from tutorials, YouTube channels, plugins/software, anything goes for this first post.
One of the most recent things I've stumbled across recently was Baphometrix's Clip-to-zero series. While I don't work on music that needs to be competitively loud, the in-depth series helped provide a new perspective to incorporate into decades-old mixing habbits.

I also really appreciate the work Dan Worrall is doing these days: https://www.youtube.com/c/DanWorrall
To build on that - despite bike companies trying their hardest to over complicate things - e-bikes are fairly straightforward to build, maintain and modify.
Tons of great (and safe but not cheap) DIY kits out there too which help make old bikes new again.
My e-bike is an old 90s MTB with a 220km range ( at the lowest assist level and 32km/hr top speed). That doesn’t include the benefits I get from regen braking when riding it in urban / suburban areas.
