Introduction: Make an LED Kite Out of Recycled Parts!
Hey there, I hope everyone is safe and healthy during this pandemic. Well, staying at home I realized I had some old and unused electronic circuits and faulty mobile adapters. Being an electronic enthusiast and an avid kite flying fan I wondered, wouldn't it be great to combine both of these interests. So I came up with this LED kite which can obviously fly like as it is supposed to and brighten up the sky. You can fly it in the evening or at nigh and enjoy the unique view!
Let's get building!
The most important component of this build is the LEDs of course, and more importantly they should be small and as light as possible(we don't want to add unnecessary weight to the build). I had this old LED lampshade which no longer works and upon opening it I found lots of SMD LEDs, perfect!
So I went ahead and desoldered 3-4 of them while making sure they don't get damaged while I take them out.
Step 2: Selection of Connecting Wire...
Well, to keep the build as light as possible, it is best to use insulated copper wires that can be easily salvaged from old mobile chargers . I had a faulty mobile charger and an LED driver that contained such pulse transformer and inside it was the thin insulated copper wire we need. This copper wire is quite enough to supply the necessary current to the LEDs. I desoldered one of the capacitor and removed the core and took out the insulated wire.
Step 3: Soldering Wire on to the LED
It was now time to solder the copper wire on to the LED terminals, using some sandpaper, I scratched off the protective enamel layer of the wire and soldered two wires to each terminal of the LED
Step 4: Testing the LED
After I soldered one LED with the copper wire, I got this 3.7V 18650 Li-Ion cell to test the LED, You can use any other 3volt to 3.3volt supply to test this out. As you can see, it works great!
Step 5: Selecting the Battery....
电池将安装在风筝上，并将直接为LED供电，而不会与风筝一起悬挂的长线，这显然不是一种实用的方法。所以我从旧蓝牙耳机上获得了这款小型60 Mah锂离子电池。这款电池超轻，几乎没有对构建增加任何相当重量，完美涂抹。为这些LED提供电源的替代源可以是串联甚至CR2302 3V硬币电池的小按钮单元。
Step 6: Making a Total of 3 LEDs
I made a total of 3 such LEDs with copper wires soldered to connect it to the top, left and right corners respectively. All the three LEDs are connected in parallel such that they can be powered with a 3.7V battery. I tested them with the small Li-Ion cell as well and it works like a charm!
Step 7: Getting Yourself a Kite
Being a kite lover and an avid kite flying fan, I had a few kites at my home to which I tied the necessary knots and it was now ready to fix the LED and battery.
Step 9: The Battery Charging Feature
I made myself two of these kites and they look amazing! It was now time to test these out in the evening or at night. Make sure that you have a good steady flow of breeze so as to assist the kite maintain altitude and you have good control over it.
I hope you like this build, don't forget to check out the video in the next step and do look out for the test flight and while you are there, consider subscribing to my channel which will motivate me to share more such content with the community.

So you just connected few LEDs with battery. Everybody knows how to do that. But the most important - how did you make a good flying kite?

Those tiny LEDs are surprisingly bright!

Yes they are! It was really nice so see them glow up so bright during the night time :)
