    If you do underwoods test, you'll know your charging system is working. If it's working, that is how you test your regulator 🙂

    Just for sh*ts and giggles, I'm going to temporarily install the capacitor on my set up. I have an MGL radio, which is not highly regarded around the hangar, and since it seems to be getting worse without anything else seemingly changing, I suspect it's a bit dodgy. But it can't hurt to put that capacitor in the circuit and see if the radio improves. Ill report back on the results. Could be a week or two.

    The battery is already doing that. If not, the capacitor would be internal otherwise your whole system is relying on the installer dong that correctly- for instance if people are leaving them off because the Carmo doesn't need it, then B & C would be getting a bad rap. I feel either they are playing it safe by recommending you use one (if it's not needed it won't make any difference) or else maybe their design makes the same amount of noise as the Ducati 🤷‍♂️

    I used to be an auto electrician 😉

    Right you are. I think we talked about this before. My point is I don't think there is a need for a switch mode system, particularly since we've had this type of 'alternator' from before there was such a thing. With these low current alternators, the output amperage isn't that great. 22 amps total output for instance compared to about 5 to 10 amps for a rotor field. Totally doable with the same hardware, whether that was relays or now with transistors

    I can't remember if I bought my Carmo from the Aussie distributor or not. I guess I did. Maybe different manager now? I didn't have any dramas, but that was several years ago Incidentally, my Carmo runs at a solid 14.3V
  7. danny_galaga
    Except maybe at the very lowest rpm, the alternator will be putting out more than 14V. Not sure of exact figures but I would guess easily over 20V if no load. I think on a 3 phase car alternator it's over 50V. In the olden days (say 40 or so years ago) the regulator consisted of a relay. Below a certain voltage it was closed and above a certain voltage it would open. In this way it would vary it's rate of vibration, depending on the load, which had the effect of varying the voltage. Of course now it's done with a transistor. Same principle though.
  8. danny_galaga
    Sorta. A switch mode power supply ramps up the frequency several thousand hertz before then converting that to the required voltage. There isn't a need here. You aren't converting a voltage, just regulating it.
  9. danny_galaga
    In any case, max 22 amps for a few minutes. Well below the 60 amp peak mentioned before 😇
  10. danny_galaga
    The battery will only be able to draw the maximum 22 amps I think. That's theoretically, as presumably there are other loads on. Radio, lights etc. it will only the draw heavily for a few minutes after starting, since it will be charging up. The current draw between the battery and alternator is governed purely by the difference in voltage between the two. If there's nothing wrong with the battery it will charge up and the batteries voltage increases. If you have an ammeter you should see the amps drop down pretty quickly after a start. Longer if the battery was flat

    I would think so, if you mean that were you to install the Carmo, you won't need it anymore. But it can't hurt to leave it, if that's easier for you. My plane only has about 3 hours flying time now, but all good so far. Radio did have some sort of problem, but that was occuring whether the engine was running or not.

    I'm very happy with my Carmo, although since it was a new build I wired accordingly. Some things that appealed to me- NOT Italian 😄 Less wiring No need for capacitor (either it runs much more quietly, or there's suppression built in) When the engine isn't running, nor is the regulator. It's a mystery to me why the Ducati one can flatten your battery. Perhaps the Ducati bike ignition switch is wired appropriately. I think it might be compatible with Li Fe batteries too.

    I saw a video a few weeks ago on FB of a (coincidentally golf related) golfer hitting a hole in one after skipping the ball off a water hazard. No way that's real, must be ai I thought. After a bit of a look around, I found it was posted on YouTube YEARS ago. Sometimes truth is stranger than fiction... ⛳
  14. danny_galaga
    🤷‍♂️ Whatever gets you through the night. I also don't debate moon landing deniers. Nothing to be gained from it...
  15. danny_galaga
    Having watched the video interview of the pilot, it's case closed. You may as well be telling me theres no stars in the background of moon lander footage.
  16. danny_galaga
    Here is the pilot talking through the incident, including reviewing what he did in that video. I'm out and about so can't really listen in. One of you can tell me if he says the video is fake
  17. danny_galaga
    Interesting that the pilot hasn't said anything about it 🤷‍♂️
  18. danny_galaga
    Dunno man. Not saying Juan Brown is an expert on ai, but you'd think someone would pipe up about it if it was fake. There would be a lot of knowledgeable people following Juan. Note too that the pilot and his grandfather (who owns the plane) both comment here. Again, if they are real and the video was fake, you'd think one of them would say something. Or if both those profiles are fake, someone would call bs 🤷‍♂️
  19. danny_galaga
    Mate, they ended up going over sand traps etc. It would be nice if they could make one of the fairways. Next time theyll be sure to plan their route to follow the length of the fairways in case they have an engine failure at low altitude 🤷‍♂️
  20. danny_galaga
    News story because the first clip makes you wonder if it was ai!
  21. danny_galaga
    Well done. It almost looks like he deliberately parked it right at the end 😄
  22. danny_galaga
    He may not have to worry about that anymore.
  23. danny_galaga
    At 13,000 ft I'm wondering if there's a mandated amount of time you are allowed to fly in a regular aircraft, without oxygen. Maybe some hypoxia setting in? I would imagine you'd normally train to look for skiers etc in the path of your anticipated take off path. And that this guy just didn't see anything until the very last second.
  24. danny_galaga
    What are we talking about...
  25. danny_galaga
    Yes, saw this recently. What may be the biggest game changer may be the sodium ion battery production. These don't burn, and don't need excessive amounts of controversial minerals.
