I have an Adeept Robot HAT, but the Blue Robotics BlueOS works natively with the Navigation hat (it’s probably pedantic, but neither of these two hats meets the requirements of Pi Hats). I was looking to see what the functionality of them both was, and ended up making a back-to-back […]

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 […]
At the same time as sorting out Passwordless Sudo on my Ubuntu virtual machine, I am trying to make it match my fairly default Raspberry Pi or other Linux box setup. My default username on a Raspberry Pi is still ‘pi’, not for any real reason other than nostalgia. And […]
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 […]
BlueOS is Blue Robotics Raspberry Pi software to control ROVs, it combines the functionality required to control robots and low-cost hardware
I have put my registration in for PiWars 2024 – Disaster Zone. PiWars is “The Raspberry Pi Robotics Competition”. PiWars is a Non-Destructive robotics competition run by members of the Cambridge Raspberry Jam. It will be held on Saturday 20th and Sunday 21st April 2024, in Cambridge UK. Full details […]
I can’t quite remember how long I have been interested in seeing what is under the water, I have been writing my thoughts about building an ROV on my old site for a while. I picked up a copy of the book, “The ROV Manual – A user guide for […]
Relays are a kind of electrically operated switch that opens and closes the circuits by receiving electrical signals from outside sources. In this post, we are going to look at mechanical relays. Relays receive an electrical signal and send the signal to other equipment by turning the switch on and […]
