Multi-channel USB-HUB

1. At first, I wanted to make a round HUB because of XXX work, and later it was upgraded to a spherical HUB. 2. Initially I wanted to add a transparent case to the outside, but the volume would become very large. This is the shortest USB female port I have found. 3. It took more than N hours, tossing and turning all night, rejecting countless plans, modeling with 3D models, and piecing together as few PCB modules as possible. In the end, only three different PCBs were needed to complete it. 4. Stamp holes are too expensive, so I finally chose through holes and connected them with electronic component pins.

PS: I think this small finished product is completely in line with this event. It does not have a fancy 3D printed shell and is completely built with PCB and components. It has a HUB with practical functions and can also be filled with USB lights to turn it into a creative lamp. Whether it is hung up or placed on the table, it is full of creativity. Even a single finished product can be regarded as a small work of art. Up to 11 USB devices can be mounted on one unit, and it can also be cascaded to mount many such spheres.

Creative PCB is not only the shell of the finished product, but also the substrate of electrical connection properties. It is not only the support of the structure, but also...

The following is a simple welding process. A HUB12 PCB is printed in a 10*10 PCB, and then it is cut with a knife... After all, the cost of the three models is slightly higher, so you can see some scratches on the edges.

In order to avoid welding errors, I printed an A4 connection crease with USB flow arrows on it. First, weld the three groups together so that the three sides can form a stable shape. After putting it together, there are 120 small connecting metal pins and 240+72 DIP solder joints. It cannot be said that it is too easy to complete one. . . . . Sometimes I suddenly see it, it looks a bit like China's first generation satellite - Dongfanghong 1! This is a photo of a USB device plugged in. If the USB disk is not enough, it can only be plugged into a card reader. The computer shows all the plugged-in mobile devices. One of the USB flash drives may be broken. The icons appear strange wherever they are plugged in, but they still work?

• [ ] I used a U disk lap running software to read and test all U disks, and you can see the test speed.

! ! ! Of course, it is not only a HUB, it can read a USB flash drive, which is too weak. It can also be filled with lights and turned into a creative home furniture. ~ When you are out and about, you don’t have to worry about your friends’ mobile phones running out of power and having to take turns charging them. One port goes in and 11 ports come out, and you can plug in 11 mobile phones to charge at the same time ~ Come back later. .
