"Can you really make a sound??"
Zhou Jiangping was shocked, what kind of black technology is this
The problem is, it's fine if others don't know the principle, but Zhou Jiangping also intervened in the design of the switch, and even he didn't realize the sound principle of this thing in the first time, which is very confusing.
As for the switch, Zhou Jiangping is very clear about its function and structure, let alone these broken cardboard boxes. Zhou Jiangping watched Chen Mo put it together the whole time.
How to put them together can have such a chemical reaction
Zhou Jiangping turned the paper piano around again to observe its structure carefully.
The only thing that is certain is that the function of making sound is done by the switch itself. The game Chen Mo just made should be a simple piano simulator. As long as you know which key the player has pressed, you can make the corresponding sound on the switch.
But the problem is, how does the switch know which key the player pressed
Zhou Jiangping focused on the handle behind the paper piano again.
"Could it be... an infrared camera?"
Zhou Jiangping remembered that there was an infrared camera on the right handle of the switch. Obviously, it could read the movement and changes of the keys inside the piano, and send this information to the switch to make corresponding sounds.
"It's fun! This thing is quite strong!" Zhou Jiangping held the paper piano in his hands, and couldn't put it down, "But... can this thing really play music?"
"Of course I can."
Chen Mo took the paper piano from Zhou Jiangping, and played "The Pure Land of Ultimate Bliss".
Zhou Jiangping was shocked, can he really play
And the sound is pretty good
Of course, there is no absolute standard for whether the sound quality is good or not. Zhou Jiangping is not a professional in music. In his opinion, there is no difference between more than one hundred headphones and one or twenty thousand headphones. This paper piano The timbre depends on the speaker of the switch, but for an amateur like Zhou Jiangping, the sound is passable, and it is not much different from ordinary mobile phone amplifiers, electronic pianos and other equipment.
Zhou Jiangping looked at the paper piano: "It's amazing! How did you come up with it, Mr. Chen?"
Chen Mo smiled: "This is originally a reserved function of the switch. When doing motion sensing and infrared sensing, it has actually been reserved for consideration in this regard."
Zhou Jiangping asked: "Then... besides this paper piano, can I make other things?"
Chen Mo nodded: "Of course it is possible, only unexpected, not impossible. I will make another one."
After Chen Mo finished speaking, he went to the pile of cardboard boxes again, found a relatively large piece of cardboard, and finished it in one go.
The gadget I made this time is very simple, it looks like a weird robot with six legs. Of course, it is obvious that it is lifted by the robot. This thing can be made with only one piece of cardboard, and the six legs are just for it to maintain balance.
Zhou Jiangping was still wondering, what the hell is this
I saw Chen Mo put the two handles on the left and right sides of the robot and click them, and then took the switch screen.
There are only two very simple buttons on the screen. Chen Mo presses the left button, and the left foot of the six-legged robot moves forward; press the right button, and the robot's right foot moves forward. If you press and hold, the robot will circle in place, if you press both together, the robot will move forward in a straight line.
Zhou Jiangping was confused: "What kind of black technology is this?!"
Chen Mo handed over the switch screen to Zhou Jiangping, and Zhou Jiangping played like a child, having a great time.
The structure of this robot is very simple, and it can only move forward, but Zhou Jiangping was extremely surprised by such a simple gadget.
The question is, how exactly is this done
Zhou Jiangping also took a special look at it. This little robot is completely folded out of a piece of corrugated paper. There is no power device on the six legs below, and it is even impossible to bend. So, how does this gadget move according to the requirements of the switch
Zhou Jiangping stared and studied for a long time, and found that the secret of this thing lies in the vibration of the handle.
When the left handle vibrates, the left part of the paper robot will move forward under the action of the vibration. As for the specific principle, Zhou Jiangping is not clear, but what is certain is that the paper box is relatively light and The robot's feet are specially made into this 30-degree sharp angle shape to make it walk more smoothly. Without these two points, the robot's ability to move may become very poor.
Chen Mo said: "This thing has a special way to play, you can try the button on the lower half of the screen."
Zhou Jiangping clicked on the screen, and the paper robot stopped moving.
Chen Mo put his hand about 15cm in front of the paper robot.
Zhou Jiangping was very surprised to find that the robot moved!
Zhou Jiangping himself didn't press the switch screen, and didn't send any movement instructions to the robot, but the robot started to move after Chen Mo's hand!
Moreover, the accuracy of this movement is very high. Chen Mo deliberately moved his hands in different directions and made various turns. As a result, the paper robot could keep up without any obstacles, and the reaction was extremely sensitive, whether it was turning left, Turning right was almost in sync with Chen Mo's hand movements.
It feels like teasing a puppy with a piece of sausage.
"Is this also due to the infrared camera?"
Zhou Jiangpin looked carefully at the screen of the switch, and found that there was a small display on the screen, on which was the picture taken by the infrared camera of the switch handle. Obviously, this camera can "see" the position of Chen Mo's hand. After sending it to the switch, the switch will control the vibration of the two handles and move towards the position of Chen Mo's hand.
Zhou Jiangping tried it himself, and found that the recognition of this thing is really high, and the smoothness is beyond imagination.
"It's amazing, others use the handle to play the switch, this one uses the switch to play the handle!"
Zhou Jiangping was completely convinced. If the principle of the previous paper piano is a little easier to understand, the principle of this paper robot is very puzzling.
So many things can be done with just these two small switch handles
Use vibration to make the cardboard box walk? This is simply a genius idea!
Zhou Jiangping asked: "Mr. Chen, will you tell me that there are more fun ways?"
Chen Mo Yile: "Of course there are more ways to play. The function of the Switch controller is very powerful. It itself is a very powerful somatosensory device. When it is released normally, there will be more interesting ways to play. , and even allow players to create their own gameplay.”
Zhou Jiangping was silent for a moment, and said with emotion: "This thing... is indeed much better than pop-up books. What's the name of this cardboard box...?"
Chen Mo smiled: "It's called... hard box player!"
