In my last post, “Get your hardware for Arduino Underwater ROV”, I described most of the hardware I use to build Alioli ROV and how I plan to use it. In this post, I will show how the hardware interconnects with each other and the boards I have built. During the process of building Alioli […]
In my last post, “Finishing the frame for an Underwater ROV”, I gave all details about the design I used to build the frame for Alioli Underwater ROV. In this post, I will show what hardware I will use and how to use it. Until now, I have been looking to get together and control […]
In my last post, “How I designed the frame for my Underwater ROV“, I gave all details about the design I used for the frame for Alioli Underwater ROV. In this post, I show what I did to build my submarine frame. To get everything together, I put screws in all junctions, as shown in […]
In my last post, “Underwater Alioli ROV“, I shared all the information I got from the Internet to build my Underwater ROV. In this post, I will explain how I made the frame. The main thing the ROV needs to become real is a frame, something to rest on. After checking several designs from different […]
This time I have decided to write this article in English because I have been able to get a lot of information. Thanks to that, most of the information I found to help me with this project was in English. A long time ago, I tried scuba diving, and after some time, I decided to […]
🇬🇧 Read it in English, “GenCreate, GenUpdate, GenDetail and GenDelete“ En el último artículo describíamos Codenerix GenList para comenzar a usar los listados de CODENERIX. Ha llegado el momento de ver como crear, ver, actualizar y borrar la información de esos listados. En este artículo hablaré sobre GenCreate, GenDetail, GenUpdate y GenDelete. En primer lugar cabe decir que cada uno […]
🇬🇧 Read it in English, “GenList“ Anteriormente hablábamos sobre CodenerixModel para entender como se construye un modelo funcional con CODENERIX. Sin embargo, para que todo funciocune en Django, además de los modelos también hay que definir las vistas. Para permitir visualizar los contenidos webs existen a disposición del programador un conjunto de vistas heredables, todas ellas basadas […]
🇬🇧 Read it in English, “CodenerixModel“ En el artículo anterior hablábamos sobre CODENERIX y sus bondades. Ahora vamos a comenzar una serie de artículos que permitan profundizar en esta tecnología. Para que todo proyecto Django pueda soportar CODENERIX adecuadamente es necesario dar algunos pasos importantes que aseguren el buen comienzo del proyecto. No voy a repetir que la forma […]
Tal y como Google anunciaba en su blog oficial, aquellos usuarios que accedan al calendario desde la web comenzarán a ver un nuevo diseño mucho más limpio basado en el estándar de Material Design. Aunque el diseño es la nota más llamativa, Google ha buscado ofrecer nuevas herramientas orientadas, sobre todo, a profesionales. Ahora podemos […]
Poodle se convierte en una amenaza para la red, se recomienda desactivar SSL3 del navegador. Hace tan sólo 2 días Google reveló una nueva vulnerabilidad que afecta a la mayoría de las comunicaciones en Internet y que a pesar de tener un bonito nombre oculta efectos potencialmente desastrosos.

In my last post, “Get your hardware for Arduino Underwater ROV”, I described most of the hardware I use to build Alioli ROV and how I plan to use it. In this post, I will show how the hardware interconnects with each other and the boards I have built.
During the process of building Alioli ROV, I went through several changes, most of them because I learned from the experience and improved the process of soldering and implementing boards. For example, I started building my boards in the latest integrations because it made it easier to keep the table clean and more comfortable since I didn’t have so many cables on my table.
The mainboard for the Alioli ROV is an Arduino Mega 2560 R3:
The power I will need for Alioli ROV is:
I need 12V (motors), so I use a Voltage Stabilizer from 12V to 5V (HW-638) and a Voltage Converter from 5V to 3.3V. Engines will get their power straight from the battery since the rest of the system will get their power from the Voltage Stabilizer. In this way, I am protecting the circuit from the noise of the motors when they start and stop. After the voltage stabilizer, it will be a Reducer Regulator Module from 5V to 3.3V to provide 3.3V to any circuit that needs it.
I decided to build 2 boards: the first is to reuse the Arduino Power Supply Module from the kit I bought. Hence, it provides me with several pins at the same voltage level, and I can also use the switch to power on and off during tests. The second board is the one I will use when the testing phase finish.
Many of my modules work with I2C, and because of that, I decided to make a board just for all of those. In addition, I thought it was a good idea to attach the RS485 communication board to compacter the final result. To build this board, I used wires (30AWG 0.05mm²) with a silicone cover, making it easier to sell and manage. Some of the sensors work at 3.3V, so I have used a level converter to communicate 3.3V sensors with the rest of the bus at 5.5V (you can learn more about level shifter here “How a Bidirectional Logic Level Converter works? Logic Level Shifter“). WARNING: watch out, SDA & SCL are in different colours to show different bus voltages:
During these days, I will get Prototype Boards for Arduino Mega 2560 R3 to prepare buses and test everything with the existing software. In the next post, I will publish the rest of the hardware I have been working on, and I will interconnect everything, the “Learn how to Build an Engine Controller for your Alioli Submarine UAV Drone“.
