    Hello, I'm looking ...passionate about programming, creative and has a strong attention to detail. This project requires a good understanding of the Raspberry Pi platform and ability to work with existing libraries. If you feel like you have the right qualifications and experience, please contact me and we can discuss this project further. I need an app to manage a SSD backup on a raspberry Pi powered with a UPS and 12V charging station. Compatible with any windows based computer, as a new drive, wirelessly. With automatic switch on/off for automated backup (RTC or when power switches off or when data transmission is over). And an integrated GPS tracker for the device. Code has to be commented so I can understand, adapt it and customize if needed. Preference for french comme...

    design 12V PCB for EWP Zakończone left

    I'm looking to hire someone to design a 12V printed circuit board (PCB) for an Electric Winch Platform. The PCB should have a large size, with more than 6x6 inches being ideal. The complexity of the PCB should be moderate, with several components required. Finally, the PCB should be single-sided, with no preference given to either single- or double-sided PCBs. i have aready designed some PCB but are told the relays need to be safty type relays not compliant to EWPs requirements This project is quite specific, so I'm specifically looking for someone with knowledge and experience in designing PCBs, particularly with 12V systems. The ideal candidate will possess a strong understanding of electrical engineering principles, be highly detail-oriented, and will tak...

    I'm looking to install a 12v off grid electric system with solar and lights and a few other things everything is majority wired up plus I have all the thing I just need to make sure everything is perfect. Its on a custom van I've been building. Specifically, I'm looking to set up a solar power system. I have a sorta detailed plan I can provide for the layout and design of the lighting and switches. Additionally, I have about 12 wires that’ll go to the fuse system and about 4-8 other components including fuse spots and other 12v rv system . If you think you have the skills and experience to help me out with this project, please get in touch!

    arduino coding Zakończone left

    ...with me for this project and other projects expected to come in the futur. The actual projet is not complex, however, the requirements and complexity will increase over the coming months. Specifics: - The project initially involves an Arduino board acting as the Management module for a water treatment system. The module must take control of the following: - a water flow sensor, - a backup 12V battery to activate when the 110V or the 220V source goes down - an electrolysis module that must generate 2A and can adjust Voltage accordingly to maintain a stable 2A. - a lcd display the information - a connection to wifi/LoraWan/LTE for real time data transmission - a MQTT broker. I have a good idea of the sensors I want to use, but I am open to suggestions from the coder. S...
