The construction of Weissenburg University has not stopped in the past three years. New buildings continue to expand along the lakeside, and many single-family villas have appeared in the mountains to the south, where professors live.
The lake in front of the university has begun to be called "University Lake", and no one uses its original name.
Heinrich resigned from the Royal Mage Corps last year and moved to Weissenburg University as a professor. He formed the "Lightning Academy" with his students and some colleagues to specialize in teaching and researching electrical magic.
Because Frederick gave him a large investment last year, a large number of students signed up for this college this year, and everyone came here hoping to make a fortune in the future.
Under his example, the royal mage corps was temporarily unsettled, especially the new mages who had just joined the corps a few years ago and were still waiting for qualifications, and they also thought about changing jobs.
After all, the Royal Order of Mages was the strategic force of the Rhine League. Frederick did not want to poach too much, so he asked them to form a mutual aid and co-construction unit with Weissenburg University. On the one hand, members of the Order of Mages who wanted to make money came to the university to teach and conduct research, and on the other hand, they were allowed to
On the one hand, students who are interested in joining the military are allowed to intern in the Mage Corps.
However, Frederick complained a lot about the royal group of mages. Last year, he promised 10,000 florins for them to develop a gramophone that could be promoted. As a result, there is still no trace of it, so I am afraid I have to do it myself.
Frederick found Heinrich in a laboratory with red bricks and red tiles similar to a factory building. He first let Mingxiao wander around by himself, and then went in to see what they were doing.
More than a year after the broadcast was launched, Heinrich and the others have achieved some new results.
Several students are assembling an antenna. This kind of antenna has a circle of iron on the outside and filled with empty magic crystal powder in the middle. It is more than one meter long and about the thickness of a chopstick.
This kind of antenna allows the transmitter to transmit the signal farther, and also allows the receiver to receive weaker signals.
In April this year, the Wesen Army supporting the Wesen Territory relied on a new wireless communication system to direct a company to divide into three groups at night to surround the enemy's camp, which was five times its size.
As a result, Frederick had a big plan - to get the telegraph out.
However, in order to complete this plan, the equipment needs to be improved, which is the focus of Heinrich's current work.
When Frederick arrived, Heinrich had just finished hand-making a magic array plug-in. This thing can be directly inserted into the magic array that sends signals like a graphics card, and its function is to determine the frequency of the signal.
"Principal," Heinrich raised his head and saw him and asked, "Is something wrong?"
Frederick replied: "Nothing, I just came to take a look and you can do your business."
Seeing that he was fine, Heinrich went about his own business without saying a word, and began to invite my students to come over and do experiments.
Frederick didn't understand Morse code, so he made it up now. It's not difficult to make up a set of Rhine letters, Praian letters, numbers and punctuation marks.
There is a new set of equipment in the laboratory today. It is long like a box. Put the black paper tape through it. There are empty slots on the upper lid to put the letters. After arranging the contents, press the letters, and the corresponding words will be printed on the paper tape below.
hole.
On the other side, the student wound up the clockwork of the paper feeding device, and the gear driven by the clockwork controlled a pair of rubber rollers to advance the paper tape.
The paper tape will pass through a device, the upper part of which will glow, and the lower part is a photosensitive magic resistor. The amount of magic elements passing through is proportional to the intensity of the light shining on it. The holes in the paper tape will shine on it as time passes.
, the signal sent out after the transmitter is turned on is also different.
Frederick watched quietly as they sent out the words "The principal is watching!"
After about five minutes, there was movement at the receiver. The student immediately opened the paper tape feeding device there. As soon as the white paper tape was fed half a palm long, the steel needles on the upper and lower sides of the paper tape began to flash.
The electric sparks left a string of black traces.
The content was quickly translated, "Salute to the Principal - Yu Nuremberg".
Frederick nodded with satisfaction, but there were still some problems. The received signal, whether it was "·" or "-", was relatively long.
"What's going on?" he asked Heinrich. If this problem cannot be solved well, "·" may become "-", which will eventually lead to misreading.
Heinrich replied: "The paper feeding speeds are different. Some are fast and some are slow. It is difficult to unify."
Frederick thought for a moment and realized that the rotation speed of the roller should be controlled by the escapement of the clock, so he said: "Let me solve this small problem. I may go on an expedition this fall or next spring. Can I make it in time?"
Heinrich answered firmly: "If it is a voice like broadcast, it is still a bit troublesome, but the current dot and horizontal signals can be transmitted very far, but I still recommend building a transfer station every 200 kilometers to avoid signal distortion.
.”
Frederick nodded and said: "I have arranged for people to buy land. Recently, I have produced more voice communicators for the army. They will be used during expeditions. They may sell for a fortune."
Heinrich naturally agreed when he heard that there was money to be made, and then said: "I have an idea. The communicators sold are equipped with a self-destruction device. If someone tries to dismantle it, it will explode."
Frederick's mouth twitched and he nodded in agreement.
He continued: "I plan to build a number of telegraph stations in major cities in the Rhine League, and then build them in important ports on the North Sea and inland seas. These telegraph stations can transmit information to each other, and we can study in this direction next."
"In terms of speeding up the input and output of information, you may want to refer to Professor Ogilvy's calculator. You can discuss it with him when he is free in a while."
Heinrich immediately took out his notebook and wrote it down.
Frederick motioned for him to go out with him, and the two went to Heinrich's office nearby. After cutting off the sound, he said: "I also want a small communicator that can communicate over long distances, mainly for spies.
This requires leaving specific frequencies for them."
"No problem." Heinrich agreed, "I will pre-allocate the frequencies for broadcast, telegraph and certain communications."
Frederick added: "I have an idea whether the radio can be used as an invisible beacon to determine the position of ships at sea."
"For example, a ship at sea can receive broadcasts from two places, and then measure which direction the broadcast is from and how many degrees it is relative to true north. With these two data, it can be displayed on the map
Measure your position on the top.”
After hearing this, Heinrich started thinking and picked up the white paper next to him to write and draw.
Frederick did not disturb him, just sat there quietly and made him a pot of tea.
"Theoretically it's possible." When Heinrich raised his head, the sunset had already filled the sky. "The broadcast signal can be shielded with high magic resistance materials. Then make a shielding tube like a wooden barrel. Its
The strongest signal is received when the opening is facing the direction in which direction the transmitter is. Although there will be some errors, I think it is enough for use at sea."
After hearing this, Frederick thought for a while, nodded and said, "This method sounds feasible."
"This is a big business. Coastal cities need to buy broadcasting systems. If the radios are sold, the captains who are not short of money will definitely buy them. It doesn't matter if they are more expensive. After all, they can save their lives."
Both of them had bright smiles on their faces, as if they saw countless gold coins waving towards them.
