Have you ever had a flashlight “ruined” by some ancient batteries becoming a permanent part of the flashlight? In my latest instructable I have an example home-re-built flashlight I made recently. If you have some good flashlights ruined by bad batteries please see this tutorial as an example of how you might turn it into something new and working again!Continue reading “Re-flash-light project”
The Repeater-START app now includes repeaters imported from the New England Repeater Directory. This makes the app and repeater listing much more useful to those in Massachusetts, Connecticut, Vermont, Rhode Island, New Hampshire and Maine! This expands the repeater-START app and any other applications needing an offline, fairly complete listing of repeaters worldwide.Continue reading “New England Repeaters added to Hearham.live Repeater Listing and Repeater-START”

The new Hearham live repeater listing has been up for one week and now has hundreds of repeater listings up! If you’ve been looking for a database to use for your offline app, this may be it! Unlike other repeater listings this aims to be up to date and allow for timely comments to go out to all users of the repeaters to know about any outages or changes.Continue reading “Announcing Hearham live repeater listing”
Another important part of many mobile apps is location tracking – there is, fortunately, there is a built in api for most Linux systems called Geoclue that should work… There is even a Python-geoclue package, but after some digging I found that this package does not work in Python3. In fact it’s hard to find examples or documentation, if you look at the files of the package you can see there are some basic docs:Continue reading “Building a mobile app for Linux, part 4: GPS/mobile tracking”
With a working Linux application, it’s time to test it out on a real (well, virtual) device. Starting up the emulator for debugging in the same way as before, to debug this project I ran:Continue reading “Building an amateur radio app for Librem Phone, part 3: Responsive on small screens”
In the previous post I showed how to add some icons to an application showing OpenStreetMap, with Python and GTK+. Next, I’ll show how to make a listing of nearest repeaters to selected area. The listing of all repeaters is in the local array, and since there is a .distance(lat,lon) that gives the distance to a point, the list of repeaters can be sorted by closest to a certain point that is selected – in the on_button_release function. The Python Gtk guide shows an example that can be integrated in to the code to add a Listbox. The listbox should be “self.listbox” so various functions can access and change it. Below the other widget/control code, this must be added, within a gtkScrollWindow or adding many items will expand the window awkwardly:Continue reading “Building an amateur radio app for Linux, part 2”
In the US, various hunters and fishers use the Bureau of Land Management’s maps. There are of course several apps that can let you add BLM maps…
- Avenza has some maps provided by BLM specifically for avenza app.
- Gaia maps pro has had the public lands feature for years.
- Osmand has not the greatest support for viewing what land area you are in and looking at, but many local points of interest are in this app that are not in others as it uses the openstreetmap which can be added and edited by locals with places they actually care about. Also unlike most other offline mapping apps it is open-source, available on F-Droid store, and very extensive, and respects user freedoms and an active developer community.
For some time I have wondered why the public domain BLM land use maps aren’t an option in Osmand, I tried mobac but found no way to get the maps I wanted, but after a bit of research I found the answer! Here are the steps to add land use maps to Osmand. Continue reading “Adding BLM Land Use Maps to Osmand on Android”
