    Sorry, i hat to write in german... Toller Kanal. Besonders für alle die bei RG SAT angefangen haben. Leider hast du da einen Nischenkanal in einer großen Nische. Aber für die Menschen die sich für cubesats interessieren wird es eine Goldgrube sein. Ich gebe zu ich gehöre zu denen die die private Raumfahrt und die ganzen cubesats fruher eher skeptisch betrachtet haben. Mittlerweile sehe ich aber was das für Möglichkeiten eröffnet. (Was leider in den deutschen Medien nicht wahrgenommen wird) Es war nie billiger und einfacher einen eigenen Satelliten in den Weltraum zu bringen als heute. Es sei denn man wartet bis morgen. Mit den Cubesats sehe ich das ähnlich wie früher mit dem Amateurfunk. Dort wurde auch in den Hobbykellern getüftelt und erfunden, und dabei ist auch einiges rausgekommen. Ich kann mir vorstellen das man über cubesats auch "einfacher" eigene Ideen in den Weltraum bringen kann, und hier und da sicher tolle sachen rauskommen werden. Und dank Leuten wie dir, die das ganze auch open source machen wird sicher in Zukunft noch vieles mehr möglich werden.

      @buildacubesat 19 дней назад

      Thank you! :) I don't worry too much about radiation at this point, mainly because there are a bunch of other things that need to work before radiation can even become a problem. And also in LEO, radiation still seems to be relatively benign. My list of priorities up until the high altitude balloon test flight next year are: 1. Get it to work at all, 2. Thermals, 3. SI/EMI

    Hi Manuel, Just found your channel and the videos are great. What checks are actually performed by these launch companies to make sure the sat is powered off and can not emit any rf until deployment? Best Graham

    • @buildacubesat
      @buildacubesat 27 дней назад

      Hi Graham Thank you so much, I am really happy to hear that! :) Great question! I think this mainly works through providing the necessary documentation to that end. Are you familiar with the NASA CubeSat 101 document? Check out chapters 6.2 (Transmitter Survey) and 6.7 (Electrical Report). Basically you provide detailed diagrams of your system and a list of all transmitters so the launch provider can verify that your inhibit logic is sound. I think this is how it work for most missions, although I think it's plausible that a LP may conduct independent RF/EMI/EMC tests for more exotic payloads. Would that be a topic you would like to see a video about at some point? Maybe I can get someone form Exolaunch to talk to me about these things.

    • @grahamwaffle4949
      @grahamwaffle4949 20 дней назад

      @buildacubesat Hi Manuel, Thanks for the reply. This would make for a great video. I have read those docs, but I have not seen anything concrete about what actual tests are done to prove it. Attestation documentation from the maker of the device is false security, it's pretty surprising that launch providers accept this. But this is part I am trying to find out about. Best Regards, Graham

    • @buildacubesat
      @buildacubesat Месяц назад

      Thank you :) Do you mean the 5K figure? That's my guesstimation of what launch costs for a 2U may by the mid 2030s (when I plan to be ready to launch this). So no hard evidence there, just hoping for economies of scale.

    The next thing I would like to try with the LTM4675 (after getting the PMBus telemetry to work reliably) is reading its internal temp sensors and characterize the temp rise when at different currents and at ambient pressure vs. in a vacuum. Also I just noticed a discrepancy between the telemetry and the actual current displayed on the adjustable load at 08:05 just now. That's one more thing to look into. Hope you like the episode :)

    It is much more reasonable to have a vertial (like sitting parallel to rails, just behind solar panels) carrier board with set of M.2 (or shatever you want) connectors with goldfinger receiptance. Those carriers could also be stackable. In your design you would stuck with soldering M.2 connectors, as they usually have plastic or even metal tabs to hold connector on PCB.

    • @toshictoshic
      @toshictoshic 2 месяца назад

      If you still want to have a stack-up of boards, look at the proper mezzanine connectors, like Conan line from Amphenol.

    • @buildacubesat
      @buildacubesat 2 месяца назад

      Thanks for the input! This sounds interesting, do you have any visualizations of that layout? I had looked at a number of different board-to-board connectors but kept coming back to M.2 because using simple 2 layer PCBs of various lengths as connectors seems very flexible and cost-efficient. It is completely unproven though, so I may very well fall back on a different solution. I don't remember if I had evaluated the Conan line, will look into it. Thanks again!

    Are you planning on having the boards, even prototype ones, professionally assembled? The LGA form factor is impossible to hand solder, and I don't know well they work with hobbyist-level oven/hot air/hot plate soldering. In my experimentation I always try to stay away from packages that can't be easily soldered, even if in practice I usually use an oven - all too often, I've had to touch up the solder by hand.

    • @buildacubesat
      @buildacubesat 2 месяца назад

      I am going to break the PMIC and DC regulator sections out to stamp-sized PCBs that that fit on a MHP30 hot plate, hoping that this would make assembly DIY-able. I have never worked with LGA before, just BGA, but i figured the usual stencil, paste and hot plate method should work here... But yes, if all else fails, these may end up needing PCBA service then. Thanks for the heads up, that's really helpful!

    I think the Figure 5 at the end of the video is correct because it shows the +Z vector as a circle with an "x", which is the usual way to indicate a vector entering the displayed surface. If the +Z vector is entering the displayed surface it means that the displayed surface is the -Z surface, I believe.
