Chapter 203 Remote Control

After Lin Hong and Arthur got home, they did not leave immediately, but waited at home until 2:00 p.m., because the performance was relatively late.

Orlando is not at home. Vina drives Lin Hong and Arthur. Their destination is an area in the southern suburbs of Boston, where factories once stood, but due to the introduction of the Environmental Governance Act, many factories have moved away from here, which is said to be developed soon. However, at present, there are more white tin sheds, with all kinds of strange signs for recycling and repairing scrap cars.

Compared with the quietness and elegance of other places, it seems a little dilapidated, and the surrounding environment is also very bad. It seems that you have come to the industrial ** era of the last century.

Huge factories have become warehouses and places where mechanical waste is stored.

Mark's "Life Survival Laboratory" is located here. He lives in a warehouse, next to a huge waste acquisition station.

Vina drove the car directly into his warehouse.

Lin Hong came out of it and was deeply shocked by the various holding machines he saw in front of him.

The first thing he saw was a giant machine with a height of more than four meters. It had a car-modified chassis and no head. Instead, it was replaced by two iron chains full of shark teeth, staggered with each other and at a specific angle, like a prehistoric beast, roaring up to the sky with a bloody mouth.

In front of this sharp-toothed beast, Lin Hong also saw a huge machine lying there. Later, he learned that this was an industrial machine tool, which was used by Mark to add steel monsters.

The whole warehouse is surrounded by a variety of equipment, welding equipment can be seen everywhere, lathes for various purposes, punches, and rusty unknown equipment parts.

Lin Hong had a feeling that he came to Grandpa Xu's waste collection station for the first time. Of course, all the things here are steel products, and they are all large pieces.

Although Arthur said that Mark's things were not interesting, he was obviously very interested when he came here.

After getting out of the car, I ran around and drilled around in the steel jungle.

"STONE, come here." Arthur finally listened to it next to a cylindrical mechanical device.

Lin Hong walked over and felt a little strange to see the machine beside him.

The shell of this machine has not been disassembled, revealing a very precise internal component, with very fine metal fan blades, and elliptical metal blocks like bullets at both ends. It looks very complicated and full of an alternative design beauty.

"What is this?" Lin Hong asked.

"Jet engine." Arthur picked up a piece of iron from the ground, which happened to have a U.S. Air Force logo "It seems to be on a fighter. Cool!"

Lin Hong couldn't help but be shocked when he heard this.

Where on earth did Mark get this thing? You can even get the engine on the fighter plane. That's awesome!

He went closer and checked it carefully and found that Arthur's words might really be right. This thing seemed to be like that.

Although he has not seen it with his own eyes, at least he has seen photos of fighter jets in magazines. Combined with the big thing in front of him, it is really similar.

"Haha, kids, what do you think of this?"

After a few words between Mark and Vina, they came over with a proud smile on their faces.

"It's just so-so." Arthur was just praising, but in a blink of an eye, he pretended to be very careless. "It's just a scrapped engine, nothing to see."

"How dare you say that this is ordinary?" Mark looked at his face and said, "This is a real turbofan engine! In the eyes of the military, this is a product that has been scrapped, but it is not in my hands! Look, little Arthur, I will definitely bring it back to life!"

After saying that, Mark looked at the engine in front of him with an obsessive face.

"You picked this thing up again from the army, didn't you?" Arthur hit his uncle mercilessly, "How many dollars a pound? Twenty? Or thirty?"

Mark jumped up when he heard the words: "How can it be so cheap! Do you think these things can be picked up by the roadside? To tell you the truth, this thing has a lot of money, sixty-five dollars a pound!"

When Lin Hong heard this, he almost laughed out loud.

At the same time, he was also very surprised. When can high-tech things like engines be sold by pounds?

Under his inquiry, Mark told Lin Hong how to obtain the raw materials he usually made "mechanical creatures".

Usually, he will go to the scrap collection station to have a look, such as scrapped car engines, as well as chains, tires, lifting arms, etc. of large construction machinery, which are his favorite things. He usually "borrows" these things from the waste station. Anyway, it is not very valuable. In addition, the people in charge of the waste acquisition station here also like to watch his performance, and usually don't care much about it. If you are stingy, you will symbolically give some money.

However, Mark's favorite thing to do is to go to those reduced-scale military bases to find things. After bargaining, he usually transports tens of dollars per pound from the military base, including all kinds of military-grade machine tools, submarine parts, strange motors, and all kinds of strange things. There are electronic components, thick steel bars, and even brand-new spare parts worth more than 100,000 dollars.

In order to make electronic equipment, Lin Hong also bought electronic or mechanical waste, and then assembled some interesting equipment by himself. Originally, he was already very good, but compared with Mark, he found that he was nothing.

This is a professional-level ashes player!

Lin Hong and Arthur rushed around the venue, as if they were looking for treasure in the treasure house. After seeing good things, they would call each other for observation and tasting.

Mark began to visit some strange metal blocks in the middle of the warehouse. Some of these metals were frames and some were huge truck tires. They were placed irregularly and were very casual.

After a while, a huge trailer drove in and jumped down from it. Several people, Mark's assistants, who were Mark's fans, did not get paid, volunteered to help him do something, and enjoyed it.

Lin Hong thought that the performance was about to begin, so he immediately ran over.

Mark took out a remote control from a box on the ground. After starting the button, the sharp-toothed monster Lin Hong saw just now began to move!

This situation made Lin Hong jump.

How can it be controlled remotely?!

Lin Hong knows wireless remote control toys, but it is the first time he has seen such a large remote control device.

Mark will operate the sharp-toothed monster to climb the trailer along the track, then took a few people back into the car and drove away.

"Mark, aren't you performing here?" Lin Hong asked strangely.

"No, the venue here is too small, and the performance will be held in the evening. It's still early. I'm waiting for two people in Orlando now. Before the performance, there is another battle between me and him. Mark put the remote control back in the box.

"Can I have a look at this remote control?" Lin Hong is a little interested in this remote control.

"Of course." Mark is not surprised by this. Boys are very interested in these things.

Lin Hong took the remote control to his hand and studied it.

The remote control in his hand is square, with two left and right joysticks in the middle, which can be operated up and down, left and right. There is a stretchable antenna in the center of the top. Under the joystick, there are also some adjustment buttons, which are marked with some English abbreviations. Lin Hong doesn't know what it means.

However, he understood the English written on one of the labels, which said "six-channel receiver".

"Mark, what do you mean by six channels?"

"This indicates direction control, that is, the direction of 'front and back, left and right' plus 'up and down'. In general, only four channels, or even two channels, are enough. But when you remotely control the model, you need six channels, because the model involves lifting.

As Mark explained, he debugged a toy car on the ground. And there are many of the same toy cars on the ground.

"Is this using radio to communicate?"

"Yes."

"As far as I know, the interference between radios will be very serious. How to solve the problem of mutual interference?"

As a ham, Lin Hong is very familiar with radio, but he has never tried to use this signal as control.

"It's very simple, just set a few more frequencies. Generally, the remote control has two frequency bands. For example, the frequencies of ordinary toys are 27MHz and 49MHz, while my remote control is a little more high-end. The frequency range is 72MHz and 75MHz. When competing with others, just use different frequencies to control it.

When Mark saw that Lin Hong was interested in this, he simply stood up and said, "Do you know radio?"

"Yes, I'm ham."

"Really? GREAT!" Mark praised when he heard the words, and Lin Hong's ham identity immediately increased his weight in Mark's eyes.

"Have you ever been exposed to the principle of wireless remote control?"

"No. I've never played it before." Lin Hong shook his head.

"Actually, it's very simple. I'll give you a general idea and you'll understand." Mark is in a good interest.

In fact, explaining what you know to others is something that many technicians like to do. This impulse to share "good teachers" is, on the one hand, based on the desire to communicate with like-hearted people, and on the other hand, there is actually an element of showing off in it.

Mark, especially such people.

Unfortunately, every time he preached his theory or knowledge like Arthur, his nephew disdained it. This smart little boy embarrassed him every time, but he didn't mind it and still tried to influence him.

So, when he saw that Lin Hong showed enough interest in it, his good teacher's character immediately exploded.
