• Chrome be gone

    Dont get me wrong. I love the new car, I really do.
    Driving it is great… Its just the look of it I cant stand.
    For the most part, its all the chrome.

    Duno exactly what about the chrome, it just triggers a shudder in me when I see it.

    So, paint or wrap?
    I wanted to be able to undo it for any reason (not that I would not like it, but just wanted it reversible).
    So wrap it was.
    Got a quote of 800 bucks. Yes, eight hundred dollars to do it.
    Yeah. Nah.
    Ordered some vinyl off Amazon for 8 bucks. Just a small sheet to start.
    Spent about an hour doing one side.

    Better, Much better.
    Ok, so ordered about 30 bucks of vinyl this time and spent another hour or so doing the other side.
    Then did the front and back chrome bits, bumper and emblems and number plate surrounds.
    That leaves the wheels. What to do about the wheels…. I was not confident about wrapping them and not scratching them up, so plastidip to the rescue.

    Better. Much better.

    Should I also the roof racks?


  • Catalina Island

    Freddy and I decided to get away for a few days together. (Its been a while – yeah yeah).
    Our destination for no reason other than we both wanted to see it… Catalina Island.
    Its due west of Dana Point, not far off the coast, but far enough to make it a little interesting.

    Of course, to get there, you have to take a boat. We chose the smaller of the two that fairy back and forth. Turns out we won’t be doing that again. The bigger boat is much faster and smoother. It means another 1/2 hour to our drive to get to the point where it docks, but eh, it will be worth the drive to save the sea time.

    Once on the boat we just sit and chat. It took a solid hour and a half. Neither of us felt great going over, it was pretty rough and the staff warned us as much. (It was a pretty windy day).

    When you get there, you have two methods of getting around, walk or golf cart.
    Cars are not banded on island, but its just so small that the number of cars is severely limited (I’m told the wait list is about 10 years long). Where as every resident automatically gets a golf cart permit. So yeah, noisy, smelly golf karts are everywhere.
    Here is the local supermarket parking lot to give an example.

    Some people try and hot them up, or deck them out, make them a bit interesting, but for the most part, they just look like golf karts. There is also more than the fair share of them broken down in the streets. I guess it costs too much to get them repaired and its very expensive to ship them back to the mainland to dispose of them.
    And yes, 99.9% of them are two stoke…. Electric ones were very rare. Reason being most people don’t have a garage and so have no way of recharging them. You are not allowed to drape a power lead across the sidewalk (footpath), so it limits your recharge options a lot.
    We looked at hiring one, but at 50 bucks an hour, it was a bit rich for us.

    So, we walked. It was beautiful weather and just a delight to walk about taking in the sites.
    First place we walked was up a hill!

    Well worth it.
    Short version short, we walked 7 miles the first day. Had a nice fish and chips lunch…

    Just hung out and had a nice day.

    Next day the goal was to check out the botanical gardens and the Wriggly memorial. Yup. More walking.

    It was the weekend of the annual marathon, so there were some runners out and about. Nice uphill slog for them from the starting line, but they turned around at the memorial.

    The memorial is just amazing. High up on the hill (but not at the very top) and pretty massive given its location. 100 steps exactly from the base to the top.
    It would have been amazing in its day, as it stands now its still very impressive and beautiful with brass doors, blue tiles and amazing marble inlay.
    Photos do not do it justice, but here is a panorama of the inside along one wall.

    Remember, you can click on pictures to make them bigger….

    We hung out there for a good while just soaking up the place.
    It was also very quiet when we were there, we had got up and got going pretty early and so not one was around, the runners were well below us and focused on running, not sightseeing, so yeah, it was bliss.

    I wanted to hike to the top of the island and see the Ocean on the other side, Freddy said that as long as I took my time she was in for the hike up the hill, so we set off to the summit of this smaller ridge.

    Lets try this little movie… Not sure it will work for everyone, but eh, try something new…

    If you cant play it, its a short movie of me puffing trying to hold the camera still and pan from one ocean to one sea.

    All in all that day we ended up doing around 14 miles on foot. Nice effort.

    Next morning, it was just a matter of taking the boat home. We goofed and did not get in line quick enough and so the only seats left were outside…. It was rather cold (we were NOT dressed like the people in this photo), but on the upside we did see a few whales and Freddy was thrilled about that.

    All in all a very nice weekend. We have decided that island life is not for us. I love my high speed Internet and 2 day Amazon deliveries and Freddy likes long drives.


  • Inmarsat ACARS

    Sorry guys, did not realize that I had not blogged about my Inmarsat fun and games…..

    There are a few different ways that aircraft communicate back and forth with the airline.
    This blog is about satellite.
    There is a geostationary (not moving, very handy, no tracking needed) satellite named Inmarsat (sorry, forget the exact number, there are a few of them) that carries, among other things, aircraft data.
    To pick it up you need a small dish, an antenna, SDR (software defined radio) and a computer to run some software. We are going to be looking at the ACARS data on 1.545 GHz.

    First things first. As it happens, I knew this day was coming so have been collecting satellite dishes behind the shed for a while, turns out I kinda lot track and have about 5 of them back there…. hey, its good to have options.

    Next, you need an antenna or feed horn. So I did what all good hackers do and wound one around a toilet roll.

    Next up, attache it to the dish and see if you can get some signal.
    And we did, but the mounting was a bit unsustainable and looking out the window was also not the best, but here is how it looked for the test.

    Next thing to try was jamming it in attic.
    Let me tell you about the nice words that were expressed in getting the dish through the manhole and aligned to look at the satellite.

    There is alfoil over the roof and it really killed the signal…..
    Freddy came up with the idea of putting a pole on the side fence and hiding it behind some bushes out there, so thats what did.

    Finally we had a good strong signal and a nice solid mount.
    The eagle eye among us might notice that the feed horn is not the toilet roll. And your right.
    I modified a GPS antenna and its much better as its smaller, flat and has better gain.
    So with a 30 foot long USB lead, we now have a signal in the garage where we can use the software JAERO to decode the signal and stream it to my main dashboard.

    You can see it here; https://thebaldgeek.net:2880/ui/#!/4

    Long term my plan is to get another GPS antenna and have a second decoder running to double my data rate.

    So yeah, that’s how I pick up aircraft text messages from space.
    Cool beans.


  • Noisy computers?

    We have been interested in building a one stop shop website for all things aircraft tracking and decoding for some time.
    To this end we have put up a satellite dish to get Inmarsat messages, 136mHz antennas for ACARS and VDL data and for HF we have been running an Alinco receiver.

    Everything has been working great, but I have always struggled with a really high HF noise (static) floor. It massively impacts my ability to pickup and thus decode the weak signals coming from the aircraft all around the world (the radio at this frequency – 6mHz – can hear aircraft from pretty much around the globe). I have been tinkering with the antenna and noise suppressors and all sorts of things, but it has always not been great.

    The last straw was when this guy commented about my HF reception;
    http://forums.radioreference.com/threads/adsb-acars-vdl2-data-decoding-website-for-southern-california.383104/#post-3068413
    (At the very bottom of that thread/comment.)
    1% of the traffic. Ouch.
    But he was right, I had a feeling I was not doing great. Getting around 70 messages a day from aircraft.
    I honestly suspect any one or all of the 90 or so computer devices that are running 24×7 at the house.

    Anyway, buddies to the rescue.
    I have been chatting with two guys from Phoenix a fair bit and one of them is big into both aircraft and HF and he also noticed that he was getting more traffic than I was, but he lacked the computer skills and gear to decode them.
    So yeah, we made a deal. If he picked up the signals, I would decode them.
    Thus he has dedicated one of his radios to aircraft and I wrote some code to transfer the raw data from his place to mine where I do further decoding and display it on my website.

    BOOM! I cant believe it but we went from 70 a day to 3000+ a day.
    A.M.A.Z.I.N.G!
    We are now almost drowning in lovely lovely aircraft data from around the world.
    Both he and I are thrilled.

    You can see the data here; https://thebaldgeek.net:2880/ui/#!/5
    Its been running great for the week or so and neither of us see why that won’t be the case for a good while longer.


  • 3D aircraft trails

    Been busy tinkering with aircraft tracking stuff.
    One of of the more ‘pretty’ things I have done is got working a 3D map of the aircraft trails.
    Its been a bit of frustration getting this going, but it turns out that my graphics card driver was way out of date (who knew). It works Ok for day to day web browsing and text stuff, but when pushed in the graphics world, it sure matters.

    So, you can check if things are going to work Ok here; https://cesiumjs.org/troubleshooting/

    Run their little example and zoom around the world. If it all flows pretty good, then you are in with a chance to get the aircraft to show up.

    Here is a sample of what you are going to see;

    You can tilt, pan, zoom and generally move around in the whole 3D experience.

    I have set up a few URL’s to speed things up. Most of my visitors are from one of these places, so it helps them get started on their place of interest.
