  1. Gearing up for a series of projects using raspberry pi to learn python among other things, and it seems like lately when Amazon says one day shipping, you won't so much get it in one day, more like you'll get it one day, maybe. Starting to feel like I'm personally underwriting the specialty cable industry, and I haven't even started running basic projects yet Scope creep, my old nemesis, we meet again.
  2. I had a run in with "unifying receivers" from logitech, those are not ready for prime time, everything is fine, until you have more than 1.
  3. I can't seem to find a setting for persistent brakes, where is it?
  4. You ever have one of those days when you don't think that you could lose any more respect for humans, only to have them prove you wrong?
  5. Looks like I'll just be scrapping that whole idea, the setup is just a troll by the devs, they should just remove the parts, if they're gonna make it useless, they should just leave it out completely.
  6. You can build them in chunks and assemble them in orbit. You might try the aircraft hanger, but you can't assemble things in the parking lot as far as I know.
  7. Makes sense in a way, so scaling to the bigger convert o tron it is then.
  8. I've been trying to make a fuel depot on mun, (for the chuckle value) but I can't seem to cool a convert o tron jr, using 8 tons of cooling system hardware. Is there some trick to what kind of cooling? placement? My "try really hard" version was 30 tons, half of that was thermal control systems, how do you keep the temperature stable? Is this just not possible under any circumstances?
  9. The magic number is 1 fuel cell per 2 motors, and indeed looks 1337, I tested it with a 6.3 ton model, 6 burners, 3 fuel cells and a t-200 worth of fuel for the cells, it managed to burn a bit over a third of the xenon. (8103m/s starting tank, at 1.8m/s) This should not only scale pretty well, but "tree" pretty easily, making detachable segments that stack and thrust together. (no idea of how to maneuver such a thing, not that far along in the process, but it's an interesting question.) I guess I'll get some practice docking stuff playing with it.
  10. I think a "branched tree" xenon mother ship still has legs, I made a somewhat practical 30 ton model with an "any direction" solar array. (the "bad" angle drains the batteries at 10/sec, which yields a 15 minute max burn, at 1.8m/s, 7km/s on-board.) As a munar tug boat, it's not a bad solution. The solar array is a problem for scaling, for a mothership I might go with full on fuel cells and save myself the lift nightmares of a 15m radius, haven't tried that yet. (fuel cells are also bulky) If I did a grand tour, it would be way scaled back from 1500 tons, and no kerbals to kill, but I want a munar mining facillity. (cooling a convert-o-tron, can it be done?) In the most recent update (1.11.x) it seems a lot of mods are broken. (they did fix a bunch of stuff in the stock game)
  11. Well, I've already sank my teeth into the problem, I don't feel like letting go without a fight. (6 day burn, I suppose that mod allows warp during burn?) It takes about 2.5 hours to run a test at eloo (the sailboat I just tested had something like 25 gigantors, generating 4 per sec at "peak angle", so well less than 1/ps for each fully exposed gigantor at eloo.) Still, I'm a pretty clever lab rat, there's a couple things I haven't tried yet. Still, I don't hold out any hope that this would scale to 1500 tons, and not in a form that would carry you beyond duna anyway. Meanwhile, a challenge is a challenge, how big can the xenon systems scale? and what does it do to counter the lack of sun at eloo in a not horrible fashion? I don't really do kerballed missions, I fly into things too much, but it might be fun to setup a much smaller group of probes , dropping them off would still be quite a trick, even more so, because I do not fly with the least amount of elegance, the fuel would be monumental. (my "super probe" could probably visit 4 maybe 5 planets, but not land anything, and not much science on board) The peak power point for the xenon engines seems to be a 3 thruster system, at least for deep space. (the only configuration that can yield 1.8m/s with long range in the dark.) Anyway, I guess I'm off to play with fuel cells for the moment, thanks for the tip on fusilages, I'll be playing with the nervs next.
  12. I'm working at maybe 1/10th scale to the beast you're working on, but you've given me something to chew on, the rather flat response from the solar panels at eloo (and the 42 minute burn to get out to a test range) have put a crimp in my thrust budget, but that's only part of a grand tour, I'll have to spend a couple days cooking up some deviltry and testing it on a heavy ship.
  13. Are you using regular fuel tanks and just scrapping the oxygen? (been up a while trying to get a large scale xenon setup running, the current one looks like a camping stove, working out a good multi-angle solar geometry is proving a little much, given that it needs to launch from ground, but it's easy mode, so it won't snap if I breathe on it, mostly it's a question of scaling, so I'm not trying to press the rest of the situation. Just seeing how far I can bend it before it breaks, so far 48 engines at 91 tons and something like half of that is just fuel in the tanks it can dispense to other ships. I'll see if I can drive by eloo with a better solar geometry)
  14. Wait, you're using nerv's instead of xenon? Why dear and fluffy lord why? xenon is the only build I can stack 17km/s of usable thrust on a probe. (BTW, if you use tweakscale, it will cut the xenon thruster in half, 1Kn instead of 2Kn, making it totally useless) I've had a good bit of playtime making long haul probes recently with xenon thrusters, one trick I can tell you is use the small radial xenon tanks instead of the stacking tanks, it greatly reduces the tankage weight factor, allowing far more Dv on the same fuel. The number 1 problem is balancing the electrical, followed closely by maximum acceleration. The "mission constraints" (arbitrary standards) required the craft to sustain a 10 minute burn time, have over 1m/s acceleration, and over 10km/s in the gas tank. I can do that with xenon all day, but I've never gotten even close to that trying to use nerv's. (that could be me failing to pick the right gas tanks, but the ships with nerv rockets couldn't ever beat a decent terrier design.) This is an interesting question, as using either tech to it's utmost requires some level of design juggling.
