Adding up these two should make no relay communication reach about 100 kilometers, basically covering most of the residential areas in the Western Region, and allowing Wudong City to obtain the battle situation on the mountain defense line at any time.
If you want to extend it further, you must use a signal amplification device.
The reason why Roland chose to develop a wired telephone was, in addition to Anna's words that aroused his ambitions, the telephone itself was indeed a very generalized tool, which was of great significance to controlling the political situation, strengthening centralization, or helping war command.
Another more important point is that Wudongcheng's current industrial projects have reached saturation.
New immigrants need to undergo primary education to digest it. The four giant industries of civil construction, mineral smelting, mechanical processing and chemical production have already occupied more than 90% of qualified workers. Judging from their due size and expected scale, it is no difficulty to swallow 60,000 to 70,000 newly joined the Western Region in one bite.
Since these industries are closely related to future wars, no one can suffer the four giants.
The most typical one is the bicycle factory. This factory that Roland first built with great enthusiasm, and the bicycles produced so far are not enough for the first military division.
When there is insufficient power, it must be the first to shut down. When there is a shortage of manpower, all workers have to go to the steam engine factory to work overtime, which is a tragic fate.
Even if Kingdom Avenue and Highway 67 are built, the carriages are basically running on the road from Changge District or other cities, because there are no horses raised in the border area and there are no supporting facilities such as stables.
Seeing that the railway tracks were being laid, the scene of citizens riding bicycles between the two places still did not appear.
Of course, Roland would never admit in front of Barov that it was his decision-making mistake, but now when considering new facilities, he would take into account the production potential of Winter City in advance.
The telephone happens to be a good tool that hardly needs to occupy production potential or manual maintenance.
First of all, it will not be put into the civilian market. Whether it is military contact or connecting the border area and the Changge area, Roland only plans to lay cables in a one-to-one way.
This eliminates the wiring process and does not require the establishment of complex wiring networks.
Second, the small number means it can be made in leisure by Anna, Mymoon and Soloya, with little need to misappropriate urban productivity.
After the electronic tube is tossed out, it will not be too late to vigorously develop civil communications.
Therefore, wired telephone is the most suitable project for research and development before joining the Taqila remnants to explore the Great Snow Mountains.
……
The development of the phone prototype was even smoother than Roland expected. By the afternoon, two simple magnet phones appeared in the backyard of Beiposhan.
It has no shell and looks like a combination of exposed coils and magnets, equipped with a hand-crank generator and a magnetic battery Dawn Mini.
Since the battery is not large, the magnetic inductor battery as thick as a finger can last for at least about a month, and he does not plan to dry the battery alone for the time being.
How to use this?My Moon curiously said, my abilities really have such a magical effect?
Roland automatically ignored the other party's second half of the sentence. It was very simple, I'm optimistic... This hand-cranked motor was responsible for sending a call signal. When the user quickly shook it, he grabbed the handle and rotated it hard. The magnetic bell on the other end suddenly made a jingle sound. At this time, it means that the phone was connected.
Then he winked at Anna, who nodded and picked up the receiver and microphone.
When the earpiece leaves the base, the switch pops up, meaning that the voice line is turned on and you can talk.The current transmitting the electrical signal is provided by the Shuguang Mini, so without the copper rod of My Moon, the phone can only ring and not transmit sound.
Uh-huh!My Moon raised his flat chest and nodded twice.
Your Majesty, can I try to speak with it?Soroya was eager to try.
And I, Ling raised her hand high.
Of course there is no problem... You are its maker, so you are naturally qualified to be the first to experience this epoch-making communication tool.Roland smiled.
There is no need to say much about the significance of the phone. It completely changed human communication habits and closely linked the distant world. It is impossible to praise it. It is just that the yard is so short that the signal will hardly attenuate, so it is enough to connect it with ordinary copper wire.
So in this quiet place surrounded by white forests, crisp ringtones kept ringing.We could have a direct call, but we insisted on doing it over again and started with hand-cranking power generation.
There is really a voice!
Sounds like Lucia’s!
Uh, what should I say?
Let her guess who you are!
The witches yelled loudly at the microphone through the wall, and for a moment, laughter echoed at both ends of the yard.
Roland also listened twice. To be honest, the prototype was not effective, with loud and low sounds, and a lot of noise, so it cannot be regarded as a qualified finished product.
However, he knew that the following work would be to repeatedly adjust the size of the reed and the distance between the electromagnet to achieve the best call quality.
Not long after, the microphone was once again reached Roland.
He smiled and shook his head, put the receiver in his ear, and spoke habitually, "Hey?
And no one replied except for the faint sound of current interference.
Almost as he had a clear understanding, he subconsciously guessed the person on the other end of the phone.
Anna…?Roland whispered.
After a while, a slightly distorted answer came from there.
I like you...Roland.
*******************
After the day of protection, Nightingale returned to her bedroom in a little depressed mood.
This is not the first time I feel like I can’t understand anything. Whenever this happens, only dried fish and ice cream bread can be comforted.
Well... there is another Chaos drink now.
Seeing Roland and Anna's intimate appearance, she felt sincere envy and a faint feeling of sadness.I thought I would adapt sooner or later, but the process was more difficult than she thought.
The deeper the feelings, the longer the thorns are.
She now understands what Wendy means.
Walking to the table, Nightingale opened the drawer, but found that the bottle was empty.
Did you get it wrong?
She opened the other drawer again, and it was still an empty bottle.
Wendy?My Chaos... As soon as Nightingale turned around, she was held in her arms by her roommate, and her proud chest almost made her breathless.
Nightingale, how many years have we known each other?Ever since you left Quinn's house in Silver Light City, you've been with me.
It's Ah... It's been almost four or five years, but my chaos...
How many dangers and hardships have we experienced along the way to get to where we are today.Nothing can destroy the friendship between us, right?
Of course, I always treat you as half of my own sister.But my chaos...
I've drunk your drink, sorry!Wendy hugged her tighter, and I will definitely give you the one I've drawn next month!
What?Drinked up?
The nightingale touched the empty dried fish bag.
All that could comfort her was dried fish, ice cream bread and Chaos drink.
Now, nothing is gone.
She heard a crackling sound in her heart.
In an instant, my heart became even more sad.
If you want to extend it further, you must use a signal amplification device.
