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…
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…

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…
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…
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…
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…
