Recycling electronics
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.
This circuit consists mainly of the following components: a solar cell, a DC pump, a 555 timer, and an LM311 comparator. It worked well and was also very efficient, requiring only power from the solar cell rather than a battery. Read more
A solar-powered water pump circuit for a place with no power outlet, with a battery. We’ll learn how to use a MOSFET instead of a relay, as well as the NE555 timer circuit. Read more
Let’s make a simple plant watering alarm circuit that sounds alarms when the soil is dry. It’s powered by a self-sustainable 6V solar cell. Read more
This is Outdoor solar lights circuits made by my son, at day solar charge to battery then night LED light up without AC line, Relay control the solar current […] Read more
We are going to show how to recycle free 18650 Li-ion battery from electronic waste. Our experience using it for almost a year, it runs well. Read more
