Haha yeah, last year I replaced my wheel bearings in my van. I ended up with a frustrating ABS code (long story short: faulty magnetic encoders on both of the new bearings). I ended up spending about the same as the job would have cost at a shop, but with a slew of new tools.

I also did a USB switch project for fun, and ended up spending probably $250 for something I could have just bought for $15, but it was a great experience. (Here if anyone is interested: https://shielddigitaldesign.com/posts/2021/susb/ )
