Coming Soon: Mobile D-Star Radio Hotspot
I am working on a new build of D-Star hotspot which will be way better than the DVAP, or DHAP. The new product will feature compact headless industrial design with super easy management and use. Here are some highlights on the unit which is currently in development: (but first, a teaser picture of the product […]
Read MoreD-Star Startup with Internet check
I wrote this script to only start the d-star daemons on a DV hotspot when there is a viable internet connection. The reason for this is to simplify “in-the-field” use and only allow the system to start when there is an available internet connection. Without this script, it was often a problem to ensure that […]
Read MoreFixing TV overscan from Microcomputers
So I recently decided to try a Banana Pro ARM microcomputer to evaluate for my next project. I was disappointed that the unit output had overscan on my TV. Fortunately there is a simple fix for this annoying problem which the folks at LeMaker do not mention in their forums. 1) Press Source on […]
Read MoreGPIO: Read input state for clean shutdown
I wrote a short python script to read a GPIO pin and watch for a state change (from a momentary contact switch) in order to execute a safe, clean, & orderly shutdown of the raspberry pi computer, since no on-board provision exists out of the box. It is necessary to ensure a clean shutdown in […]
Read MoreD-star deamon status LED driver
This script is used as an LED driver to show the operational status of the ircddbgateway & dstarrepeater daemons. If the daemons are up and running, an LED will be lit from the assigned GPIO to show simple operational status. Permission is granted to freely use and distribute for all purposes. #!/bin/bash gateway() { G1=`ps […]
Read MoreGMSK Modem Check Script
If you’ve built a D-Star hotspot and sometimes find the DV modem (GMSK modem) occasionally loses connection on the USB bus, I wrote a helpful script to check the presence of the modem and if not found on the expected device node, instructs the hotspot host to reboot and bring the system back on the […]
