We bring to your attention a review of a video on the manufacture of a solar-powered lamp. This lamp will automatically turn on when darkness sets in and turn off when it is light. Also, during daylight hours, the LED battery is charged by the solar battery.
You can start by watching the author’s video
We will need:
- solar battery 5.5 volts, 90 mAh, size 65x65 mm;
- light;
- at 3.3 ohms;
- 50 kΩ resistor;
- ;
- off button;
- silicone;
- ;
- plastic box;
- 3.7 volt battery;
- a box for the battery.
On the sides of the box, which we will use as the body, we make holes for the mounting bolts.
We put bolts in the holes.
Now you need to collect all the elements together, but before that you can take a look at the diagram of the upcoming assembly.
We solder all the elements according to the scheme, not forgetting to insulate everything with heat shrink and hot glue.
The author of the idea decided not to use the switch and set homemade as a courtyard lamp in the country.
At the beginning of the assembly, we fix the LED using silicone on the box lid. First you need to drill a hole on the cover so that the LED shines through it.
We also glue the solar panel on the back of the box with silicone.
Also, according to the author, in this case, silicone should not be spared, since it is very important for maintaining tightness.
We continue assembly. At the end, we fix the lid of the box with silicone. It is important to close all possible openings so that moisture does not enter the structure. The uniqueness and ease of use of silicone is that, if necessary, it can be easily removed, replaced with something inside the structure, and glued again. However, according to the author, a device manufactured in this way will work for about 3 years.
