  1. Sounds very interesting! Please be aware that working with radio signals and FM transmitters may require some knowledge of electronics and radio engineering and may involve legal restrictions. It is always important to comply with local laws and standards when creating such devices.
  2. "E-books are not my thing! Although they are convenient and eco-friendly, I always prefer the feel of paper pages between my fingers. I find a special charm in the smell of fresh printing and the rustle of paper that no screen can replace. Each physical book becomes special - a unique literary treasure on the shelf. Flipping pages is like a journey through history and fantasy. Plus, when reading paper books, I get away from the screens and enjoy a well-deserved rest for the eyes. Perhaps in the future many will switch to electronic formats, but for me there is nothing better than the feeling of a real book in my hands!" 🤐
  3. You could use a time delay relay. This relay would be connected in series with the power supply to the fridge, and would delay the power to the fridge for a specified period of time after the power supply to the relay is switched off. Begin by selecting a time delay relay that can handle the voltage and current of your fridge. For a 240V AC circuit, you could use a relay rated for at least 10A. Connect the 240V AC IN to the input terminals of the time delay relay. Connect the AC OUT of the time delay relay to the fridge. Set the time delay on the relay to approximately 10 minutes (or whatever time delay you prefer). The exact process for setting the time delay will depend on the specific relay you use, but typically involves adjusting a potentiometer or dip switch. Test the circuit to ensure that the fridge is not powered until the delay period has elapsed. If necessary, adjust the time delay on the relay until it meets your requirements. Try it, hope it helps
  4. I used these points while creating my college project: Planning: The first step is to figure out what exactly you want to build. Consider the size of your landing deck, the number of LEDs you want to use, and any other features you want to include. Draw a rough sketch of your project to help you visualize it better. Gathering materials: Once you have a plan, you'll need to gather the materials you'll need. You'll need a breadboard, LEDs, resistors, jumper wires, and a power source such as a battery pack. You can find all of these components at an electronics store or online. Building the circuit on the breadboard: Using your schematic and the components you gathered, build your circuit on the breadboard. Start by placing the resistors on the breadboard, then connect the LEDs and jumper wires as necessary. Be sure to follow the correct polarity for the LEDs. Testing the circuit: Once you have built the circuit, test it to make sure it is working properly. Connect the power source to the circuit and observe the LEDs. If they light up as expected, then you're good to go. If not, check your wiring and component placement to ensure everything is correct. Building landing deck: Once your circuit is working properly, you can build your landing deck around it. This could involve constructing a frame or platform, attaching the breadboard and LEDs to it, and adding any additional features you want. Final testing: Once your landing deck is complete, test the circuit again to make sure everything is working properly. Adjust the circuit as necessary to get the desired results. Hope it helps you!
  5. I can speculate that the chemical composition of the CR2032 battery contains cobalt, manganese, and lithium, but I am not sure if it can be oxidative corrosive to metals and PCBs. Perhaps, with the passage of time and storage, the chemical composition may change and transform into a corrosive oxidative compound that can leak and corrode. I usually use this source with coursework writing help for some of my study tasks, this resource helps students with basic tasks. But it's better to find something useful for obtaining more detailed information about the chemical compositions and properties of various substances and materials. Maybe if someone has any materials - you're welcome to share them with us.
