    Also, pons assinorum 😃

    I doubt there would be any point having a co sensor in my plane. It's so drafty it would be like installing one in a tiger month 😄

    My point in posting that article was more about highlighting the pitfalls off buying fake stuff , especially where you rationalise about the origin (oh, it all comes from the same factory). I could have posted an article about fake USB memory. That's a popular one. The root is rewritten to make it show as a bigger size. So instead of say a 512gb memory stick, what you are actually getting is a 64gb rewritten to look like a 512. Your computer will show it as 512, but once it gets close to 64gb full you'll get an error message or disk is full message. Definitely don't buy USB sticks from eBay or Ali express 😉 Skippy, your links a good case in point. Get the cheaper CO detector, but from Quell or wherever, not from eBay or Ali express. Reputable suppliers have to submit their products for testing. That goes for USB chargers, clothes irons, lawn mowers or whatever. If you bypass that by going overseas, you don't know what you're getting. If it's failure is not dangerous (my fake tv remote for instance) it might be worth a gamble.

    You can die or at least get headaches from CO2 as well. Asphyxiation. So it could be useful in small, poorly ventilated spaces...

    You might be missing the point. In china you can get all sorts. When the big names set up a factory there, they SET UP A FACTORY there. Pretty much every single thing for the factory is brought in. If it's Apple (or back in the day - Atari) Apple or Atari bring in all American machinery. The exact same machinery that they used in America. Every robot, every lathe, every silicon chip makey thing. Even the wiring comes from the USA. Same if it's German or Japanese. It's the same product because it's a duplicate factory. But when someone in china sets out to make a knockoff of a well known product, it's going to be all sorts of ordinary. Sometimes it's worth a punt (I got a knock off remote for my ten year old Samsung telly. Looks the part, and works just like the original). But these knock off artists do riff on the fact that people imagine that because it's from China, it must be from the same factory. It's not. So if the function is critical, get it from a reputable source. Don't get an APLE charger. Go to the APPLE store and buy the real deal. If you want to replace your telly remote with the same, well that's worth a punt. At worst, you might have lost a few bucks, but at least it won't blow up your telly 🙂

    Detecting CO2?
  8. danny_galaga
    Yes I'll check them too. Have to get a capacitor from there anyway
  9. danny_galaga
    Yes, definitely a matter of not buying critical stuff from eBay or Ali express. If you get it from a reputable source, it's still going to be made in china but to an OEM or high standard. I think even my skyecho2 is made in china, but if I saw one for half the price on eBay or Ali, well I think I'd give it a miss 😄

    Ok then I'll pay Bunnings aerospace a visit for some star washers 🙂
  11. danny_galaga
    Yes, it's from Sert Efrika

    Or lack thereof! I bought two brass bus bars for my instrument panel ages ago and noted a lack of washers. Figured I'd cross that bridge later. Well it's later 😄 I'm pretty sure when I was an auto electrician, bus bars would come with star washers. But maybe I could get away with Loctite? I was trying in earnest to keep as much steel as possible away from the panel because of the compass. But now I realise my engine VDO type engine instruments (Aviasport) have nice big steel brackets to hold them in place! So what would a few tiny zinc star washers matter? Thoughts?

    This seems such a pity. https://www.smithsonianmag.com/air-space-magazine/antonovs-in-america-3916822/

    "I'm making a habit of it" 😂 Nice to have those fields around. My kinda airfield. Glad he sorted it out 🙂
  16. danny_galaga
    It's looking good so far 🙂 I like that it looks 'sonex'. They aren't the prettiest, but the shape is part of the brand I think . And actually, being high wing improves the look

    I ended up getting a Lenovo m8. Some of my geeky friends recommended it as really good value for money. And googling around, I found at least one pilot using one. And air Norway or something use fancier Lenovo's exclusively for their EFG 😃 I live somewhere between Archerfield and Brisbane, so that's been handy for testing! @coljones VID_20230212_222710.mp4

    Yep, already wired the supplied pot remotely with a view to measuring and replacing with a fixed value. Great minds eh 😃 Cooling will be fine. It's why I bought a kit. I looked at how to work out what sized heat sink I would need and the maths didn't look fun 😄 Note that there are more caps than needed. The kit covers a few bases, including an LCD voltage meter. I left out what I KNEW I didn't need, and left in what I wasn't sure about. The fan was powered by a lm7812 to give it a constant 12v . Since I'm only feeding it 12v I just left it out and bridged it. Fan wails like a banshee though, I'm sure it doesn't need to be THAT fast! So might put in a 1-5 ohm resistor to take the edge off it...

    Just put together the little kit, leaving out the bits I didn't think I needed (rectifier, voltage display etc) . Worked. Tried to put a load on it by connecting a USB powered desk lamp. Weird performance but I put it down to the fact I was getting a 12v supply from a 240v switch mode supply. Then I did something and I think I killed it. Are lm338 easy to kill?

    I guess what I'm driving at is that it would probably be the same process for a fake 912 from China. In which case I would feel safer behind a well documented used real 912.
  21. danny_galaga
    Could be taking samples for testing?
  22. danny_galaga
    Is it possible to fit an 'on condition' engine on a 24 rego plane?
  23. danny_galaga
    And one more thing. I think on a phone nowadays 64gb is the bare minimum, since the OS is over 20gb just on its own. What sizes are you guys at, on tablets a year or so old or less? Bearing in mind I won't be using it for anything else... And was that about gdl90 again? Is that something any modern tablet can use, or has, or whatever?
  24. danny_galaga
    Ok, so built in GPS, but not necessarily phone. I guess it won't use the skyecho2 GPS in the same way?
  25. danny_galaga
    Just to be clear on the tablets - they need a SIM to navigate, right?
