  • There’s more than this required to build anything that’d be needed to survive in an automotive environment, and considerably more if you are hoping to have an open source/FOSS design that would be accepted as a suitable replacement for something proprietary, although I don’t think that was your aim (but it does sound like OP’s). I’m all for grassroots/homebrew stuff but we’re talking about a thousand kilos+ of steel and plastic being hurled down a road carrying people, in and around other people in similar contraptions. This isn’t something I’d exactly condone throwing a hackerspace’s resources and some Arduinos at.


  • Last year I drove my parent’s car which is equipped with one of these cameras that determine if the driver is distracted or dozing. And I can say for certain that it works.

    I rented two different modern (2015-2016) Mercedes SUVs. They both had systems that detected tired/inattentive driving. I was neither but after several hours on the road both vehicles would alert that it was time to take a break with a nice little coffee icon. I was conversing with a passenger, driving fine, not wandering between lanes/etc… The first time I kind of doubted myself but subsequent notifications both the passenger and myself were agreeing that we had no idea what it was upset about.

    The newer car had another sensor that would get upset if your grip on the steering wheel got too light. That was kind of neat to see how much leeway it’d give you before it got antsy.



  • I don’t do full disk encryption on my backups. I use duplicity and encrypt the backups with three gpg keys: one that is for the IT department with a known passphrase, one for the business with a different known passphrase, and my personal key.

    I’m a one man show but I set this up with the future in mind. Different data might not have all three keys, but this arrangement allows me to spin off bits of the data management as needed. The passphrases can be changed as/when needed without invalidating old backups.

    Combined with ssh certificates it helps organize my IT needs.
