使LED风筝从回收零件中脱离！

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!

事实上，这是什么让这个构建的特点是它是由完全回收的部分制成的！整体建设将耗资差不多甚至更少。我希望你喜欢这个特殊和有趣的项目。

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.

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.

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

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!

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。

我去寻找锂离子电池的原因是我希望这个项目可以充电，牢记即插即用的方法。我以这样的方式使我能够轻松插入充电机制并充分充电，然后插入LED连接以点亮风筝效果......稍后将在充电模块上亮起。

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!

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.

我用胶带将各个角落中的LED固定在并行连接中并连接它们。我固定了雄性和母线到电池和LED连接器，以便在没有任何麻烦的情况下，可以轻松插入和拔出，使用这种连接器也可以提供轻松的连接以插入充电器

要充电我使用TP-4056模块的锂离子电池，这有效地充电，用必要的充电算法和保护电池保护，如您所能看到雄性和母头提供和轻松连接到充电和LED模式之间的连接对于电池。由于容量很小，因此为整个细胞充电大约需要10分钟，并且可以轻松地使用3个LED给我15-20分钟的时间。

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.
