Build your own None Cat Auth (none cat is authorized, a respectful repelling cats system). This is a hardware implementation to repel cats in a non-harmful way. It shouldn’t be confused with NoCatAuth which is an open-source implementation of a captive portal for WiFi connections. Questions & Answers Ingredients Cooking Mix everything in a bowl and […]
Precision vs. Creativity: Navigating the Landscape of AI Language Models in Problem-Solving In the ever-evolving landscape of AI language models, precision and creativity stand as two distinct yet vital attributes. My recent exploration into the capabilities of ChatGPT and Bard, two language models known for their coherent text generation, shed light on their respective strengths […]
This post contains the conclusions of the Alioli ROV Submarine Drone and shows images and videos of it in the water. I wrote it as a diary so anybody can understand that Alioli wasn’t a straight project, but it had problems, and I had to resolve them on the way. In my last post about […]
Examples of how to work with JSON, YAML, CSV, and XML files in Python. Today I saw myself preparing some exercises for my student who is learning Python programming language, and last week he asked me about converting a CSV to XML. So I decided to publish these exercises for anybody who doubts how to […]
In this post, I describe how my own Arduino Framework for Alioli ROV Submarine Drone works. In my last post about Alioli ROV Submarine Drone, I wrote, “Learn how to Build an Engine Controller for your Alioli Submarine UAV Drone“, Recently I completed the hardware for Alioli ROV Submarine Drone. Why not use predesigned software? […]
Here is how to make a SIMCOM 7600 module work on an Arduino board (Uno, Mega 2560, Leonardo, Due, Micro, Zero, Nano, Pico), ESP8266, ESP32, Raspberry Pi Pico, MicroPython, or any other microcontroller. If your module accepts 5-10V, the short answer is the following diagram: SIMCOM SIM7600 GSM/GRPS/GPS/Bluetooth Modules will consume a peak current of […]
I will tell you about my experience repairing a cargo ship as a naval Engineer. Some months ago, you could read in the local newspaper Málaga Hoy that a large cargo ship was approaching Málaga after a major accident it had suffered in its front part. It was the cargo ship Integrador with a Panamanian […]
During our operations, very often, we use a Waterlinked Underwater GPS. This helps us to keep track in 3D of our movements and link video recording’s timing and telemetry to specific places. These experiments were done together with Andalú Sea. Some examples of these 3D tracks are: Thanks to this technology, we can position the […]
I have experimented very much with photogrammetry and got exciting results. This article talks about this experience. These experiments were done together with Andalú Sea and my friend Juan Soler. During underwater operations, we always record videos of the whole process just in case of problems and for documentation purposes. We checked a sewage outfall […]
In my last post, “Alioli ROV Boards“, I described most of the hardware I use to build Alioli ROV and how I plan to use it. In this post, I show how the UAV submarine hardware and electronics interconnect with each other and the boards I have built for that purpose: the engines, driver, board, […]
Build your own None Cat Auth (none cat is authorized, a respectful repelling cats system). This is a hardware implementation to repel cats in a non-harmful way. It shouldn’t be confused with NoCatAuth which is an open-source implementation of a captive portal for WiFi connections.
Mix everything in a bowl and plug it into the battery. The cooking time is 30 minutes plus 15 minutes for setting up more sprayers and finding the right place for your cat repeler.
It is a pretty straightforward circuit which works perfectly for repelling cats, other animals or even some human beings.
