Reborn Troops

Zhou Wanwan was standing in her small jewelry store. The glass cabinets around her were filled with all kinds of jewelry, ranging from traditional gold and silver jewelry to modern trendy designs.

However, her eyes were fixed on an exquisite electronic photo album on the counter, which was made by her herself and recorded every detail of her life from the opening of the store to the present.

"Wanwan, what are you thinking about?" Qianqian pushed the door open and walked in. Her voice was always so crisp, like a cool breeze in summer.

Zhou Wanwan raised her head, a gleam in her eyes: "I was wondering, if this electronic photo album is made into a necklace, will it attract more customers?"

Qianqian walked closer to the counter, looked at the photo album carefully, and nodded: "This is a good idea, it is both creative and full of emotion, it will definitely touch people's hearts."

"But I haven't figured out how to do it specifically." Zhou Wanwan frowned slightly, her fingers tapping lightly on the counter.

Qianqian smiled and patted her shoulder: "Don't worry, we will find a solution together. Tell me your idea first."

Zhou Wanwan took a deep breath and began to talk about her idea: "I want to make the electronic photo album into a small pendant, which can store several important photos and can also update the content through the mobile phone APP."

“This way, everyone who wears it can recall the beautiful moments anytime, anywhere.”

Qianqian listened with great interest and nodded from time to time to show her agreement: "This is indeed a good idea, but we have to consider technical issues, such as battery life, waterproof and drop-proof, etc."

"Yes, these are all problems that need to be solved." Zhou Wanwan's eyes flashed with determination, "But I believe that as long as we work hard, we will definitely find a solution."

In the next few days, Zhou Wanwan and Qianqian began intensive research and development work.

They studied circuit design together, tested various materials together, and stayed up late to discuss solutions together.

In this process, they encountered many difficulties, but also gained a lot of fun...

Zhou Wanwan and Qianqian's research and development work is in full swing.

Their small studio is filled with various electronic components and materials, and the walls are covered with design sketches and sticky notes.

"Wanwan, what do you think of this circuit board?" Qianqian held a freshly soldered circuit board, her eyes full of anticipation.

Zhou Wanwan took the circuit board and examined it carefully: "It looks good. Let's test the battery life first."

The two connected the circuit board to a small battery and started the test program. As the seconds passed, they nervously watched the battery indicator on the display.

"It seems that the battery life is not a big problem. Next we have to consider waterproof and drop-proof." Zhou Wanwan breathed a sigh of relief, but then frowned again.

Qianqian nodded: "We can use silicone seals to make it waterproof, but it will be more troublesome to prevent it from falling."

The atmosphere in Zhou Wanwan and Qianqian's studio is tense and full of expectations. They are facing the next big challenge of the electronic photo album pendant project, waterproof and drop-proof design.

"Wanwan, what material do you think is better for making the shell?" Qianqian held several samples of different materials in her hand, brows furrowed.

Zhou Wanwan took the sample and observed it carefully: "I think aluminum alloy may be a good choice. It is both light and strong."

"But what about the waterproof performance of aluminum alloy?" Qianqian was a little worried.

"We can improve its water-repellency by treating it with a special coating."

Zhou Wanwan's eyes flashed with determination, "Besides, I have a friend who works in the field of materials science, I can ask him for help."

Qianqian's eyes lit up: "That's great, let's contact him right away."

The two took action immediately. Zhou Wanwan called her friend and explained their needs in detail. After listening, the friend expressed his willingness to help and recommended several coating materials that might be suitable.

In the next few days, Zhou Wanwan and Qianqian started a new round of experiments.

They applied different coatings to the aluminum alloy casing and then subjected it to a series of waterproof and drop-proof tests.

"Wanwan, what do you think of the waterproof effect of this coating?" Qianqian asked excitedly, pointing at the shell soaked in water.

Zhou Wanwan observed it carefully and said: "It looks good, but we still have to see how it performs in actual use."

At this moment, the door of the studio was pushed open and Dr. Zhou walked in. He looked at the room full of experimental equipment and the two busy people, and asked with a smile: "How is the progress?"

"Dr. Zhou, we are testing the waterproof and drop-proof performance." Zhou Wanwan came forward and said, "You've come at the right time. We have some questions to ask you."

Dr. Zhou nodded, took the shell from them, and examined it carefully: "You did a good job, but I think it can be optimized further."

"How to optimize?" Qianqian asked anxiously.

"We can try to add some cushioning materials inside the shell, which will not only improve the anti-fall performance but also increase the comfort of the product." Dr. Zhou offered his own suggestion.

After hearing this, Zhou Wanwan and Qianqian's eyes lit up and they immediately started to improve the design. They added special buffer materials to the inside of the aluminum alloy shell and retested it.

"Wanwan, look, it passed the drop test this time!" Qianqian pointed excitedly at the intact shell, her face filled with joy.

Zhou Wanwan also smiled: "Yes, we are one step closer to success."

However, just as they were preparing to celebrate, an unexpected problem arose - the circuit board short-circuited during the waterproof test.

"How could this happen?" Qianqian was a little frustrated.

Zhou Wanwan frowned and carefully checked the circuit board: "It seems that we have some omissions in the waterproof treatment. We need to redesign the waterproof structure of the circuit board."

The two of them once again plunged into intensive research and development work. They constantly tried new design plans and tested them again and again.

"Wanwan, what do you think of this new waterproof structure?" Qianqian held the improved circuit board, her eyes full of anticipation.

Zhou Wanwan took the circuit board and examined it carefully: "It looks good, let's do another waterproof test."

The two placed the circuit board into the water and started the testing procedure.

Time passed by minute by minute, and they stared at the data on the display screen nervously.

"It seems that the waterproofing problem has been solved this time!" Zhou Wanwan breathed a sigh of relief and a relieved smile appeared on her face.

Qianqian also smiled: "Yes, we finally overcame this difficulty."
