Turning CDs into solar panels is a DIY project that leverages the reflective and conductive properties of CDs along with a bit of basic chemistry. Here’s an overview of how it can be done, focusing on the copper oxidation process: ### Materials Needed: 1. Old CDs or DVDs 2. Copper sheet or copper wire 3. Hot glue or adhesive 4. Alligator clips 5. Salt (sodium chloride) 6. Vinegar (acetic acid) 7. Sandpaper 8. Clear plastic sheet 9. Multimeter (to test voltage and current) ### Steps: 1. **Prepare the CD:** - Remove the reflective layer from the CD by peeling it off or using sandpaper. - Cut the CD into a smaller, manageable size if necessary. 2. **Prepare the Copper:** - If using a copper sheet, cut it to fit the size of the CD. - Clean the copper sheet or wire with sandpaper to remove any oxidation. 3. **Create the Copper Oxide Layer:** - Place the copper sheet in a mixture of vinegar and salt (1 cup of vinegar and 1 tablespoon of salt) and let it sit for a few hours. This will create a layer of copper oxide on the surface. - Alternatively, you can heat the copper sheet with a flame until it turns black (forming copper oxide). 4. **Assemble the Solar Cell:** - Attach the copper sheet to the CD using hot glue or adhesive, ensuring the copper oxide layer is facing outward. - Cover the assembly with a clear plastic sheet to protect it from the elements. 5. **Wiring:** - Attach alligator clips to the copper sheet (one clip) and the remaining conductive part of the CD (the other clip). These will act as the positive and negative terminals of your solar cell. 6. **Testing:** - Use a multimeter to measure the voltage and current generated by your solar cell under sunlight. ### How It Works: - The copper oxide on the copper sheet acts as a semiconductor. - When sunlight hits the copper oxide layer, it excites electrons, creating a flow of electric current. - The CD acts as a support and may enhance the collection of light due to its reflective properties. ### Limitations: - The efficiency of this DIY solar cell is quite low compared to commercial solar panels. - It’s more of an educational project to understand the principles of photovoltaic cells rather than a practical solution for generating significant amounts of electricity. ### Conclusion: This DIY project is an interesting way to recycle old CDs and learn about basic solar cell technology. While it won't replace commercial solar panels, it’s a fun and educational experiment that demonstrates the principles of converting light into electrical energy using accessible materials.
One suggestion is trying out a home made steam engine. There are videos all over the place with syringes as pistons, metal discs as flywheels, and soda cans for boilers. Please try one!
Great job 🛠️ 👍🏼... thank you very much for your démonstration... 👌🏼👌🏼 Your vidéo are very utilities 👏🏼👏🏼👏🏼👏🏼... Thank you very much for the partage 🙏🏼 🙏🏼 🙏🏼...

Do experience with sprint to see if its real
Thanks
Of course, a trick was made when he connect the multimeter. That's why not even a single voltage is produced when you replicate it.
Thanks a lot bro I almost got caped by that video
Ya liquid Kon sa han used kia ha.
Sir, up induction coil generator ka reality batau
i love your videos man thank you
Great job 🛠️ 👍🏼...
