    On the outside it looks very similar to what Michael Levin found on electrical communication between living cells. There too, the organism's cells were able to structure and repair…

    Agreed! And also, Total capacitance in series is 1/C1 + 1/C2, while in parallel is C1 + C2. Total inductance in series is L1 + L2, while in parallel is 1/L1 + 1/L2

    Nice approach! On Ubuntu 24.04 I had to loosen some AppArmor protections by creating a file: > cat /etc/apparmor.d/bwrap #include /usr/bin/bwrap flags=(unconfined) { userns, }

    Great read, thanks for sharing this. I'm also coming from software and have recently started making some hardware for personal use in my free time. The idea of selling it as an act…

    Isn't DDC the I2C bus? Interesting article about that here: https://mitxela.com/projects/ddc-oled

    Very cool, thanks for sharing! Any ideas of adding 2 gimbal motors to this for GOTO? MS6010v3 or something lighter would seem like a good fit.

    It's not limited to WiFi networks and indeed the fingerprints you suggest would be a lot better because they would change significantly over time. The whole WiFi networks idea kind…

    I see, this sheds some new light on your initial concerns. I'm aware an attacker can keep pretending to be inside an environment once they've seen it. I wasn't accounting for a sce…

    Thanks for the heads up! Good to know what's out there. Interesting that I independently arrived at something possibly similar.

    Thanks for the feedback! Rainbow tables probably won't work here since the epoch (rounded to 5 minutes) salts everything, so precomputed tables would expire constantly. You would u…

    My immediate thought after seeing the first chart was that it is inversely related to my own experience with movies in the last 20 years. Maybe there's an idea in there for a 'scor…

    OnStepX is very much pulse based as far as I understand it. I haven't encountered offloading techniques like you mentioned yet. Since both motors support (multiturn) positon modes,…

    Indeed the cost is mainly from assembly. The board itself is 2 layers, all default settings at Jlcpcb except for the color which is now black as opposed to the default green. This …

    Yes! And when you need advice on an electronic circuit you can export it in netlist format from KiCAD. This is a textbased representation of the schematic which is very understanda…

    Thanks for the compliment and links! Can you tell me more about the aircraft tracking? I've been toying with the idea of being able to select a nearby airplane on flightradar24 and…

    Yeah I didn't expect such a stark difference in image quality from the same lens when using it for day photography vs astrophotography. Just goes to show how incredible a proper as…

    Thanks, glad you enjoyed this. It's good to be in a place where you're confident things will turn out alright when you send your designs halfway across the world to be manufactured…

    Thanks! If you hook your ZWO up to Kstars/EKOS you can use plate-solving in software to find out exactly where your scope is pointed at and then adjust accordingly.
