  1. Hello. I would like to make a garden solar lamp that automatically turn on when the sun goes down. I tryed first with a transistor s9013 npn (seen on youtube), but it restricted the current, i suspect because of the internal resistance of the transistor. I decided to try the use of an Op amp as comparator, with a low internal resistance P channel Mosfet. I don't have much experience with these components, and the best way of learning is trying right? So see below my circuit. My problem is that it seem to work fine when the battery is full but the solar charging doesn't seem to b
  2. Hi Everyone, In this tutorial I am going to show you how to charge a Lithium 18650 Cell using TP4056 chip utilizing the solar energy or simply the SUN.

The total cost of this project excluding the battery is just under $5. The battery will addup another $4 to $5 bucks. So the total cost of the project is some what around $10. All components are available on my website for sale for really good price, the link
