  • I picked up some stranded skaters in the middle of nowhere in the middle of the night because they flashed SOS with their headlights after I drove past them. They had been there for like 8 hours. I’m sure they would’ve rather had a flashlight to do the work for them.

    But I agree that there should be another UI for getting to the emergency flashing. Like hold for 5 seconds or something unlikely to be used during normal operation.

    I have a flashlight that has multiple flashy settings, but they are disabled after like 5 or 10 seconds of idle power on time. So the first click turns it on, and if you wait a while, the next click turns it off.





  • I hated how these were delivered to you whether you wanted them or not. So much junk.

    They made really great fires though if you tore each page out, crumpled them up and stuffed them between the logs.

    Also interesting, I took one about an inch or so thick and shot it point blank with a 12 gauge shotgun and tiny yellow circular confetti came out, which was neat to see.



  • My guess is that the most expensive single component would be the lidar. Prices on lidars can be well over $100k. When I worked with lidar about 5 years ago, IIRC a Velodyne 128 was $160k. These robots would probably be using a 32 though, which is probably going to be less than 1/4 of a 128.

    Also, Velodyne and Ouster merged since I last used lidar. Ouster does in-device sensor fusion, which likely takes a significant load off the CPU and potentially GPU, meaning these robots may be able to get away with lower spec CPU and GPU.

    It appears that Ouster now does object detection, which is another reason these could get away with lower spec GPUs (assuming they’re using Ouster)

    Obviously there’s a lot of speculation in my response, but since there’s no teardown of the robot, and without spec sheets or a BOM, all we can do is speculate.









  • Thank you for that response, I think you did a great job helping me understand you and your wife’s perspective. I had a long period of lowness, and though I was not suicidal, some of the things you described sound close to how I thought and felt.

    The part about the suicide hotlines reminded me of is a talk my coworker did on mental health, and she said that if you don’t get along with your therapist within the first two sessions, it’s ok to find another therapist. I imagine that’s what these hotlines are like. When you call in you’re basically grabbing a random person from a crowd, and the chances of that person resonating strongly with your story on the first try is probably low. I could see folks just hanging up if it wasn’t helping, but it seems like they may have better luck if they call back again and talk to somebody different.

    At the end of the day though, if somebody has a chronic condition, alleviating it significantly is not an easy task. It seems like these hotlines have to struggle with that tension between wanting to help, but knowing that significant long term improvement isn’t easy to achieve, especially when you’re just talking to the person who is looking for help.

    I’m not going to say these resources are worthless, but they’re worthless to me and I would assume at least a few people who have similar problems. I’ve never felt compelled to reach out or search for resources like this. They’ve always felt insincere, similar to corporate PR speak or celebrity “apologies”.

    I think this is how my brother mostly felt. One thing that he was into that seemed to help was stoic philosophy. I wasn’t into it when he was alive, but happened to get into it shortly after he died and it immediately resonated with me. I wished we had gotten to talk about it more when he was alive. It certainly helped me deal with the aftermath of losing him.

    Thanks again for the response. Good luck finding your peace.
