  1. Yes, it's from Sert Efrika
  2. https://hackaday.com/2023/02/18/anatomy-of-a-fake-co2-sensor/
  3. 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?
  4. This seems such a pity. https://www.smithsonianmag.com/air-space-magazine/antonovs-in-america-3916822/
  5. "I'm making a habit of it" 😂 Nice to have those fields around. My kinda airfield. Glad he sorted it out 🙂
  6. 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
  7. 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
  8. 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...
  9. 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?
  10. 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.
  11. Could be taking samples for testing?
  12. Is it possible to fit an 'on condition' engine on a 24 rego plane?
  13. 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?
  14. Ok, so built in GPS, but not necessarily phone. I guess it won't use the skyecho2 GPS in the same way?
  15. Just to be clear on the tablets - they need a SIM to navigate, right?
  16. As good a reason as any to get the skyecho2 if it at least reduces the risk of this 😲 https://www.avweb.com/aviation-news/drone-collision-report-issued/ Imagine if that had hit the windscreen
  17. I'm only ra-aus now, and probably just using it in the one plane. Looks like I left some important details when I emailed casa so I'll just wait for them to respond and give them serial numbers etc then.
  18. Oh, that was easy 😃 Thanks kgwilson for the heads up on Enroute Flight Navigator. This gives me a free way to fiddle, and maybe even just stick with that, although I guess ozplan etc have ersa etc built in.
  19. Ok, so ive charged it up using a genuine phone charger (as opposed to a $2 jobbie from eBay). Now what 😄 The instructions say it will need an ICAO number. I've emailed casa about that but I guess in the meantime, since my plane isn't even airworthy yet, I can still play with it and see other aircraft in an efb?
  20. Heatsink isn't huge, but is designed around this fan, which mounts on posts. That should make it lighter than just a big passive sink I imagine. The kit has things I don't need so I'll leave those out. I just thought it would be easier to get something already designed than try and work out what sort of heat sink I need 🙂
  21. So a good quality 2amp charger is fine, or your PC. So it looks like I CAN pilfer my charger stash after all 😃
  22. Just heard back from uavionix: Good Morning Danny, The specifications given in the user manual are quite detailed but are mainly to prevent the use of inferior quality and often dangerous USB charging equipment. We have found that common brand name USB chargers (mobile phone chargers) are sufficient, also charging via a computer USB hub. The key recommendation is to charge the unit at least once a month using a 240V source rather than relying on in aircraft charging for long periods of time. The battery capacity and voltage can be monitored via WiFi connection to 192.168.4.1/stats.
  23. Just had a look. It's an LM338K. So 5amps. I'm hoping that even if it's a counterfeit, it can do 3 😃
  24. Yes, my kit comes with a nice heat sink AND a small fan 🙂
  25. Thing is, I'm going to have to charge it up at home more often than not. I will double check the linear charger kit I bought to put in the plane. It might actually be 3 amps or so. You guys will know the linear power supply I mean, I think it's in a TO3 package. Thing is, even THOSE can be counterfeit 😃 but I'm hoping in this case the voltage will still be clean, just not capable of as high a current draw as advertised. When I bought it, I wasn't worried because I hadnt even thought about the skyecho2
