Tracking High Altitude Balloons with Delphi and TMS Miletus

Whilst Delphi targets Windows, Mac OS, Android, iOS and Intel Linux, one gaping hole in its repertoire is the Arm-based Raspberry Pi. Taking 2020 as an example, the Pi out-sold the Apple Mac, and with over 40 million sold it’s a large target audience. So whilst I happily develop applications for all of those targets […]

HAB App Updates for sondehub/amateur

As I hope you are already aware, the venerable HABHUB system is to be decommissioned soon. This was planned to be done by now, but has been postponed to the end of 2022. This won’t be postponed again, so in 2023 there will be no more HABHUB. There’s a replacement, namely sondehub/amateur. It provides much […]

HAB Base and RTTY

Once the HABHUB server is disconnected next month, the map will stop working and you won’t be able to upload RTTY telemetry to HABHUB. However, you can if you wish continue to use dl-fldigi or fldigi to decode the RTTY, and have HAB Base show a map with your tracker on it. Additionally, HAB Base […]

Moving from HABHUB to Sondehub

As I hope you’re already aware, the HABHUB system is due to be shut down in October 2022. This system has supported HAB in the UK and elsewhere for many years now, however the hardware is old, the operating system is old and unsupported, the database engine and other installed software components are old, and […]

FlexTrak STM flight with 3D Printed Holder

Yesterday I launched a FlexTrak STM32 tracker to test my latest firmware, test my HAB Base software during a flight, and to try out a Raspberry Pi camera with a wide-angle lens. It was also my first flight using a 3D-printed tracker holder and aerial. 3D-Printing and HAB It took me a long while to […]

Raspad 3 HAB Receiver

As you may know, several years ago I built a portable HAB receiver based on the Raspberry Pi, with a Star Trek LCARS user interface written in Python. It works well enough and I’ve not revisited the project since then. Instead I developed mobile apps for Android and iOS, to run on phones and tablets, […]

4G (LTE) and Rural Broadband

This isn’t my usual type of blog post, but if you’re frustrated with slow and/or unreliable broadband, you might find my experience interesting and useful. With a lot of research, learning and testing, we’ve gone from a feeble 12Mbps down / 1Mbps up broadband to around 200Mbps down 70Mbps. How? Read on …. A Bit […]

Mini GPS Clock

Something I use more often in my HAB trackers these days is TDM – Time Division Multiplexing – where instead of transmitting continuously, each tracker transmits only during particular time slots. Since trackers always have a GPS receiver, this just requires software to sync the transmissions with GPS time. The advantage vs continuous transmission is […]

HAB Base Update V1.4.0

I’ve released a new version of HAB Basem which is intended for easy management of one or more receivers from a Windows PC. The changes are: Support for Sondehub import via UDP Support for local Sonde data from a rdzTTGOSonde receiver via UDP Map shows the predicted path and landing point of the balloon Balloon […]

UCS Flight – Video Streaming

This was a school flight, where they built the payload and did the launch, I supplied a self-contained radio tracker, and a 3rd party supplied 2 rugged mobile phones to take video during the flight. It gave me a chance to test a live streaming setup that I intend to use on all of my […]
