Jun 4, 20222022 Tour de France team sponsors — Who are they and what do they do?I enjoy watching the Tour de France television coverage, but being based in Australia, I am not familiar with most of the team sponsors (listed here). They are generally not well-known businesses or brands in Australia. …Tour De France3 min readTour De France3 min read
Dec 31, 2018Starting a new project based on an old mapImagine that you wanted to start making a new orienteering map, and wanted to use an old map or image as a basis. Here’s one way to achieve that. We’ll use Open Orienteering Mapper for the project, and some reference points from Open Street Map. The process we’ll be following…Gps6 min readGps6 min read
Jan 14, 2018Smoothing the altitude readingsThis article, part of the Arduino Radio Control Model Plane Altitude Hold series, describes dealing with jitter in the altitude readings. Jitter Even when the altimeter is motionless, successive readings can differ from each other. I’ve observed readings moving by +/- 3 metres. …Arduino5 min readArduino5 min read
Jan 14, 2018Sending radio control signals from the Arduino to the throttle and the elevator servoThis article, part of the Arduino Radio Control Model Plane Altitude Hold series, describes sending radio control signals from the Arduino to the aircraft controls. Background The Servo library does all the work for us. …Arduino2 min readArduino2 min read
Jan 13, 2018Reading radio control signals into the ArduinoThis article, part of the Arduino Radio Control Model Plane Altitude Hold series, describes reading radio control signals using the Arduino. Normally the on-board radio receiver would be directly connected to the servos that operate the control surfaces, or to an electronic speed control that controls the motor. …Arduino5 min readArduino5 min read
Jan 13, 2018Reading altimeter data into the ArduinoThis article, part of the Arduino Radio Control Model Plane Altitude Hold series, describes the technique that will be used to read altimeter data via the I2C bus into the Arduino. Having a way to read the altimeter is essential to the altitude hold project. Connecting the devices It is simple to connect…Arduino4 min readArduino4 min read
Jan 13, 2018Plane, radio, altimeter and Arduino detailsThis article, part of the Arduino Radio Control Model Plane Altitude Hold series, describes the hardware environment for the project. None of this hardware will be altered in this project. Arduino I’ll be using the duinotech Nano for this project. …Arduino2 min readArduino2 min read
Jan 13, 2018Making an altitude hold device for a radio controlled model airplane using an ArduinoThis collection of stories is about my attempt to make an altitude-hold device for my radio control model plane. I’m writing these articles as I go, so there is no guarantee that they will lead to success. The whole project might be a terrible failure. This isn’t a set of…Arduino2 min readArduino2 min read
Apr 29, 2017Adding knolls and depressions from KarttapullautinKarttapullautin generates data representing dot knolls and depressions, and saves it in the dotknolls.dxf file. The detected.dxf file contains supplementary information. I used Open Orienteering Mapper to add both files as templates. The file contains points that are tagged with useful labels, such as uglyudepression or dotknoll. The points are shown as dots, but the dots are usually partially obscured by the text labels.GIS1 min readGIS1 min read
Apr 29, 2017Adding cliffs from KarttapullautinThe Karttapullautin generates cliff data and saves in the c2g.dxfand c3g.dxf files. These files represent passable rock faces and impassable cliffs respectively. The cliff files can be added to a Open Street Map as a template. The Karttapullautin cliffs are represented a mass of short lines. Now it is easy to draw the appropriate symbols in place using the cliff data template. The rules for generating cliffs can be tweaked. They reside in the pullauta.ini text file.GIS1 min readGIS1 min read
