  • Long shot, but does anyone know of any mapping app where you can easily project a bearing/azimuth line, or a point a given bearing and distance from another point?

    The only app I’ve found so far that can come close to what I need is Backcountry Navigator, which has a terrible UI. Everything else seems to be focused entirely on GPS navigation from where you are now to a known destination; I have yet to find one that allows even basic triangulation, to be able to identify the location of an observed object.

    Fuck all that.

    Install Linux, any flavor. Install virtualbox, and set up a Windows VM. Go ahead and install any of your windows bullshit on that VM. That’s your crutch, your failsafe: a windows instance that you don’t have to leave Linux to access.

    Save snapshots before and after any changes, so if/when it goes to shit, you can roll it back to where it was still working.


  • My first thought (which probably isn’t the best method, but I’ve done similar before) is an Arduino between the mouse and the system. The Arduino normally just passes the mouse commands to the system, but it listens for the button and blocks movement if it sees the button press.

    Because it’s all done in hardware, this method would be system-agnostic. You could plug it into anything.

    I used a Teensy 3.6 for a similar project.




  • There is an IOS app for hot air balloon pilots called “Hot Air”. There is a similar app for Android that… Leaves much to be desired.

    There’s several functions that are needed. First, we need a map. We need to be able to enter waypoints and/or polygons charting landing zones, prohibited zones, targets, etc. we need an easy way to select targets, and our bearing and distance to those targets.

    For planning purposes, we need a bearing line that we can place and move on that map. We need to be able to easily drag and drop each end of the line, and get the bearing and distance between the endpoints.

    Next, we need track recording. It should record a ground track during flight, preferably with altitude information, and notes about the flight.

    Next, a wind map. The wind speed and direction varies considerably by altitude. It needs to record direction and speed as we climb and descend, telling us what altitude has winds favorable for our current target.

    Bonus points if we can prepopulate that wind map with data from a “pibal” (pilot balloon; a simple latex party balloon released and tracked with compass and stopwatch before a flight)

    Next, coordination with other pilots and ground crews. 3D location sharing between participants; wind map data shared between pilots.
