    Yes, it might be just me but I liked tinkering (and no need for surface mounted parts, legged ones were quite ok!) and coding, writing communication stuff in c++, driving loads of servos by smart interrupt code etc. and feel not so interested in just following say how a meshstatic works or just buy one.

    “Everything” also has been built which doesn’t help. Or so I feel!

      If you’re at the high end of knowledge and skill, as it sounds like you are, you are even closer to being able to take advantage of technology that exists today that is cheap now that most of us. Ten years ago:

      • a LiDAR system would have cost thousands of dollars. Today you can buy them for about $100.
      • Inconel was only available to the state-of-the-art industrial processes and was very hard to manufacture parts with. Today you can upload your files, have your parts made via additive manufacturing with Inconel and those parts shipped right to your door for affordable prices.
      • Computing power has significantly increased. TPUs are bringing down not only the cost of Tensor operations, but the energy consumption needed for equal amount of processing from 10 years ago.
      • the cost per kg for delivering a payload to LEO has dropped dramatically in the last 10 years and continues to do so. More orbital inclinations are available on rideshare flights than ever before including many sun synchronous allowing for continuous solar power. Some idiot like me can actually afford to put an object in LEO. That’s freakin’ amazing!
      • battery technology has evolved drastically in 10 years for commercially available product from cheap and plentiful LFPs to Na-ion cells that can operation without loss at - 40 °C without power loss.

      “Everything” also has been built which doesn’t help. Or so I feel!

      I can’t even imagine having this thought. Honestly, with your skill level I am getting the feeling this has nothing to do with the state of technology right now. I’m not going to pry into your personal life, but I’m wondering if you’re facing challenges that have nothing to do with technology, but are causing you distress depressing your interests in things you used to love. I could be way off, and if so forgive me for presuming.

        I don’t really know what to say, but thank you is a start, I might actually be a bit down.

        So thank you for taking the time (and whaat is Inconel 😁 TIL) writing an uplifting post for me 🙂‍↕️.

        I did tensorflow in 2016(2017?) and LEO is still in over 10-20k a cubsat no? Cool stuff though for real. I do feel like LLM is going too fast to follow in depth, but it is interesting to follow regardless.

        I went for a walk, touched grass, and remembered one of my old inventions that I never had the time to build (and my homemade 3D printer wasn’t up to the job, but my new store bought one is, probably).

        So thanks again!

          This can happen to any of us. If you need help, seek it. There’s no shame it in. We are not born with the tools to remedy everything. Many times we need to seek help outside of ourselves. Remember that life is worth living.

          LEO is still in over 10-20k a cubsat no?

          Nope! That same 1kg cubesat you’re referring to can be put in Sun synchronous orbit (meaning always has solar power exposure) for $5k-$6k on a rideshare launch that launch every 3 to 6 months. Picosats and even Femtosats are all smaller and cheaper with some less than $1k (but you may have to wait years for a launch).

          I went for a walk, touched grass, and remembered one of my old inventions that I never had the time to build (and my homemade 3D printer wasn’t up to the job, but my new store bought one is, probably).

          I’m glad to hear this! You’ve obviously got some incredible skills and experience. I hope you’re able to recapture your spark. It sounds like you’re already on the path to doing so!
