When imagining my children in the future. I was quite depressed by the worsening of the global environmental situation and the increasing pollution. Part of it comes from various e-waste. However, we still need to continue to make use of those electronic devices.
I love my children. I want them to live in a less polluted world. We are just a small part of this world. Maybe even comparable to ants on a football field. Even so, we can make a small contribution to the world for the next generation.
I think reusing them is one good solution and help contributes to us saving more.
Therefore, my kids and I remove various electronic components from unused electrical appliances and use them to create all kinds of electronic projects for our own use and educational purposes.
We hope these experiences recycling electronic circuit boards will be useful to friends, and we love you too.
Today I will show you how to recycle a super bright white LED from a broken T8 LED tube. At the present, almost every household prefers to use LED light bulbs over other light bulbs. Because it uses about 50% less energy and is also cheaper. The LED tube size T8 can be used to … Read more
