Intro: A Fashion-first Bracelet Combines 5 Gadgets in 1 for Smartphones (Part II)
Step 1: Add a Switch on the OTG Cable
I add a switch on the OTG cable to control different functions and a USB A Male to Male Adapter.
Step 2: A Self-made USB a Male to Male Adaptor
With the help of my friend, we made a chip with USB shells as the USB A male to male adaptor, which could be used as a Micro-SD card reader and connected to the charger.
Step 3: Finished (it Is Not Over Yet)
As I said before, the gadget I want to make is a wearable, so that people can wear it every day and help them when it’s necessary, such as you forgot the charging cable at home but your phone is dying, your phone is insufficient storage while capturing precious moments…
People use technology some of the time, but wear fashion all the time.
I hope the wearable could look good, be a real fashion accessory, a stylish bracelet.
I invited my friends to draw some sketches and I also designed the appearance in 3D printing.
Step 4: Part III Prototype
Thanks for God, 3D printing is really a great helper for makers.
I have never done the 3D printing before, but it is a cost-effective and convenient way to verify the correctness and feasibility. I wanna try it.
It took me almost one month to learn to use the Rhino. I really like the feeling of accomplishment when finished.
I designed the inner structures by myself and here is the 3D printing models, for protecting and connecting the two ends of the bracelet.
Step 5: Assembling Again
In order to make the bracelet in the most proper size, some parts need to be modified. I removed the shell of USB female and polished the plastic part according to the size of chip shells.
Step 6: Here It Is, the Finished Part of USB Female. Then the Switch.
Step 7: Protecting the Wires
Those welds are fragile.I used heat shrinkable tubes to protect wires, which could make them more strong when being used.
Step 8: Put Them Into the Model
One end finished. Assembling the other half.
Step 9: Making the Other End
Step 10: FINISHED BRACELET！
This the first version of prototype. As I am not very satisfied with it, so I asked for my friend to design its appearance again for improving it to a better looking.
Step 11: Manuscricpts
This is the whole story of how I made this bracelet.

And I really want to thank all that help me and give me suggestion during the whole process.
