A Review of Cross Platform Development Tools and Frameworks

It is the dream of every developer to write code once and then deploy it frictionlessly to every available platform (macOS, Windows, Linux, iOS, Android, …). This is of course very hard to do in practise, as each platform does just about everything differently. “Viva la différence!”

As consumers this is a good thing, and gives us options. As developers, it is a huge pain in the neck. Because this is a big problem for devs, a lot of people have had a crack at solving it. Every so often, we stray from the path of native development and are tempted by the sweet promise of “write once, run anywhere!” The problem is if you need to do anything close to the metal or complicated, you usually have to drop down into native code, which kind of defeats the purpose. There are some applications that are categorically not suited to cross-platform solutions. Anything that requires deep system-level integration, minimal latency, or specialized use of hardware features, probably falls into this bucket.

Reefwing MPU6000/MPU6500 IMU Arduino Library

While testing our updated Attitude and Heading Reference System (AHRS) library with a variety of IMUs, we found that there were not a lot of options for the MPU6500. So we decided to publish our own version. #MPU6500 #MPU6000 #IMU #arduino #library

New Review of our App FlightPlan on Free Apps for me website

Check out the latest review of our app FlightPlan on freeappsforme!

This app allows you to program a flight plan for the Tello Drone and then upload it to the drone for execution. You can also fly the drone manually with the app if you wish. 

While the plan is being flown, the app will display the glass cockpit.  Real time telemetry from the drone is displayed on the glass cockpit. This includes pitch, roll, yaw, velocity (x, y, z), temperature, time of flight (tof), height, battery percentage, motor on time, barometric pressure, and acceleration (x, y, z).

You can download FlightPlan for FREE from the Apple App Store.

Age Prediction API based on First Name

I just came across an interesting API that your app can use to predict a persons age based on their first name. The API is free for up to 1000 names/day. It is called agify.io (https://agify.io/). #development

You can try it out in your browser – just insert your first name instead of “david”:

BirdWeather and BirdNET-Pi

BirdNET-Pi: Using AI to identify Birds from their Songs.

Wouldn’t it be fantastic to be able to identify birds from their song? Well it turns out that you can.

BirdWeather
BirdWeather is a great citizen scientist initiative that uses volunteer stations to continuously listen for bird songs all over the world. The stations use machine learning to analyse these sounds and identify birds based on their song. BirdWeather is a living library of bird vocalizations. It also provides an indication of bird visit frequency and populations around a station, apart from those which keep quiet! You can play back the recorded songs and bird detections are shown in real time on the web site.

The artificial neural network used to analyse the recorded sound and extract and identify bird songs is called BirdNET.

BirdWeather

BirdNET
BirdNET is a joint research project between The Cornell Lab of Ornithology and the Chemnitz University of Technology that is “focused on the detection and classification of avian sounds using machine learning … [with the aim to] assist experts and citizen scientist in their work of monitoring and protecting our birds”.

BirdNET-Pi

Detection Stations
There are currently only 12 stations in Australia (including me), all based on the Raspberry Pi single board computer. You can learn how to configure your own station in our latest article on Medium – BirdNET-Pi: Using AI to identify Birds from their Songs.

Setting Up a Raspberry Pi Web Kiosk

We have a solar system and I wanted to keep an eye on our relative energy consumption and generation during the day. The SolarEdge inverter that we use has a mobile app and a web dashboard but neither refresh automatically. This article explains how I set up the Seeed reTerminal as a dedicated web kiosk to be able to monitor our solar performance in near real time. #solar #raspberrypi #webkiosk

Nexgen AHRS Arduino Library

Attitude and Heading Reference System

Our latest article on “How to write your own Flight Controller Software” is available on Medium. This article covers the Attitude and Heading Reference System (AHRS), IMU Filters and Sensor Fusion. We have released the open source Nexgen AHRS Arduino library to demonstrate these techniques on the Nano 33 BLE.

How to Write your own Flight Controller Software — Part 5

There are a number of libraries that make working with the LSM9DS1 IMU (Inertial Measurement Unit) easy. In Part 5 of our series on writing your own flight controller software we will focus on the IMU and in particular explain the best ways to convert the gyro rate and accelerometer force data to a roll and pitch angle. The yaw angle is then calculated using the pitch and roll and magnetometer data. This discussion, is in the context of building a drone flight controller based on the Arduino Nano 33 BLE.

Our follow up part in this series will explain how to calibrate the LSM9DS1 IMU and store the results plus use sensor fusion to improve the accuracy of the angles and overcome sensor shortfalls.
