In my previous posts, I have managed to get webcam feeds and Flask serving a webpage. Now I want to use NGINX (pronounced “engine x”) to bring everything together and run it all on port 80 (HTTP). I have moved the ports around for Flask and the cameras to rationalise […]

In my post about getting Flask running as a service, I included a screenshot with a large dark area as the background. In this post, I will work on filling it with an image from a web camera, which will run on the same Raspberry Pi. I will cover the […]
On my ROV, I am running the Python web server Flask. I want it to start automatically when the Raspberry Pi starts. For this, I need to make it into a Service. Flask displays the following warning on startup. Stating that you should not use it in a production environment, […]
Subsequently to the Serial interface issues, I bought an Adeept Robot HAT from Amazon. I have been keeping an eye on it for a while. The schematics and example code for the Robot Hat are available to download, which means that I can work on utilising the designs in my […]
The Arduino Compatible Pro Micro and the Arduino Leonardo both use the ATmega32u4, which has built-in USB communications. While this eliminates the need for a secondary processor or UART chip, it allows the Leonardo to appear to a connected computer as a USB device, such as a mouse or keyboard, […]
At home, I have a Raspberry Pi that I use to develop my ROV and K-9 software. Raspbian seems to have passwordless sudo, meaning you don’t have to enter the user’s password to run a command as root. I share this development machine with my wife, Tamarisk. In the interest […]
As part of my K9 and ROV projects, I am using at least one Arduino to control components such as the K9’s ears. Since the Arduinos will be fixed to the robots, I will program them via the Raspberry Pi. The version of Raspbian I am running is Raspberry Pi […]
BlueOS is Blue Robotics Raspberry Pi software to control ROVs, it combines the functionality required to control robots and low-cost hardware
I have started designing assembles in Fusion 360 using T-Slot, a lot of head scratching on how to make use of it at arbitrary lengths in my designs… I started by making a 20mm length of T-Slot as its own model in Fusion 360; This is model has all of […]

After my last attempt at getting MyOpenLab to work on macOS, I posted my question on the MyOpenLab Facebook group, where I was given the following response: Hello, what version of MyOpenLab, Java and OSX are you testing? You could test the most recent development version: https://myopenlab.org/…/distribution_macosx_3.12.1.zip The fail could […]
After the success of printing the sledge for my DIY ROV in the last post, It is now time to try and wire it up, I am using two of these Youmile 3S Battery Protection Board Modules, they claim to be capable of managing 10A, which I feel is pushing […]
