    I was sick of losing the Telemundo signal during World Cup, so I built a Web App that uses a local RTL-SDR dongle to analyze the HDTV signal and help you point your antenna... GOAA…

    ha! yea.... The camera itself doesn't know when a building gets in the way. I have some general stop angles, but it is not perfect. There is some ML in there to get rid of photos l…

    In theory it should work with any camera the supports ONVIF, which is a standard for security cameras... actually, as long as the camera has an API you could probably get it to wor…

    That is interesting! There is this cool piece of software that looked like it helped with a lot of this. It did visual object tracking with telescopes... but it is no longer availa…

    I am not sure if it is actually useful... but if folks have ideas, I would love to hear them! I worked on it mostly to see if it could be done.

    Totally - I think you could work back where the camera is based. I have the bearing / azimuth of the camera for each photo, so you could look up where each plane was at that timest…

    It should work for helicopters. In DC, alot of them do not have ADS-B and the flight paths are a little different, so I haven't managed to capture one yet though.

    That would be awesome! How fast can those mounts move? Would they be able to follow an aircraft? I have found that more zoom actually makes things a little tricker because you have…

    Thats amazing! If I lived anywhere near the water I would want to try and set something like this up.

    I posted a bit more on what I am using on the About page: http://skybot.cam/about I got all the camera gear on ebay, which was lucky. I figure since it is all based on ADS-B data, …

    I managed to get it for $500 on ebay... but I just checked and it looks like similar ones are around $1000 now, so I guess I got lucky. An Axis PTZ dome camera turned upside down w…

    I just upgraded the App Service plan I was using... It should be back now for a bit.

    You could get away with a pretty cheap hosting bill, I think a $10 VPC would be more than enough. My current Azure forecast is around $65, but that is for a couple other things too…

    Definitely - Let me build a little better dataset. I need to augment a bit because it was false detecting on some of the contrails. I built some scripts to also start building a mo…

    Good question - I just checked and my forecast for the month is $65... but I have a few other things running. One of the perks of working at Microsoft is that you get $150 monthly …

    Oh! that is a great idea. I am already tracking the camera's azimuth and elevation so I could probably composite everything to togther.

    I have been using this Docker image on my Pi and it has been rock solid once you get it setup: https://github.com/mikenye/docker-piaware

    oh yea! great point, I forgot about that. I am using PiAware to handle the decoding so I do have an Enterprise Account. I will have to check if I can make API calls for free.

    Let me know if you ever go down this rabbit-hole. Happy to give you pointers! You can get some pretty decent cameras off ebay for <$500. Since you are close you do not need much zo…

    Doing a vision only approach would be really cool. A lot of the interesting planes do not have their ADS-B transponder on. The two systems could actually work well together. My sys…
