EEWorld invites you to disassemble (Issue 7) - Disassemble the weight loss tool and see what is inside the skipping rope [Copy link]

 

You can imagine a scene like this:

Guan Guan sat on a chair, shook his body and sighed. He shouted slogans every day and gained weight every time.

Then the sister of Guan Guan threw a pair of handles with a ball tied to one end and said: Sister, here is the weight loss tool for you, jump up~

Guan Guan took it in his hand and saw that it was interesting. This skipping rope was not a long rope, but two handles with a ball each. It had a timer and could count. After searching online, I found that it could also be connected to an app with voice reminders.

Wouldn't it be more valuable to take this skipping rope apart for everyone to study rather than just letting it jump around for me?

Well, that's how willful we are. The theme of this issue is set. Let's disassemble the skipping rope~

As usual, interested netizens can post a comment to apply!

It's so exquisite! It's a pity to demolish it!

Take it apart!

Full of high-tech!

Voice reminder and connection app!

Only by dismantling it can you understand it in depth.

I applied for disassembly, hoping that I can put it back together after disassembly. . .

lanhua

If selected I disassemble:

I hope the outer shell will not be broken during the disassembly process (if it is fixed with screws, it will definitely not be broken)!

Does this kind of structure need to be demolished? It looks perfect.

Take it apart and study it.

I bought one originally, but it probably jumped less than 200 times before it was covered in dust.

Haha, that smart skipping rope is wasted. Just use a regular skipping rope.

Forum members who want to disassemble please write down your disassembly goals and plans, so that it is easier to evaluate.

Our company recently organized a sports meeting, which included a rope skipping competition. The upper limit was 5,000 jumps a day, and some people got 5,000 jumps every day. . .

5000, if it is really completed, the feet will definitely be injured. Unless it is not true

It’s true, we all saw her jumping, and the competition lasted for nearly a month.

Five thousand a day, that’s 150,000 a month…

100 in 1 minute, that means you have to jump for 50 minutes, which is not good for your health. Whoever came up with this question must have a problem with his brain!

lugl4313820

Moderate exercise is beneficial to health. Such exercise can be fatal!

Hurt your foot!

Once the novelty wears off, many things are left to gather dust.
