Chapter 199: Emergency Brainwave Project

Raising a pet at home, the most troublesome thing was still the problem of defecation.

Although he had added processing functions to BB, he couldn't let Katie defecate everywhere in the house. How to teach it to go to the toilet in a fixed place gave Henry a bit of a headache.

After all, Katie was a tiger, and although it was only a little tiger, it seemed there was no way to train it like a cat or a dog. Whether a litter box had any meaning, Henry was stunned after setting it up, and he held the basin in his hands, thinking seriously.

Speaking of which, the books in the library didn't have knowledge on how to tame beasts; for things like this, asking a circus animal trainer might work. However, Henry didn't expect Katie to perform stunts, so why look for an animal trainer?

As for communication...

No matter what kind of animal is being tamed, those who can skillfully handle it are people who are familiar with the animal's habits. Only then can they know the animal's current mood from its movements and calls.

But if there was a way to know the animal's thoughts, could he save the effort of learning to interpret the animal's behavior and calls?

The previous experience of being violently invaded by Professor X made Henry have some ideas about the subject of brainwaves. Although he hadn't designed a psychic protection helmet based on the Faraday cage principle according to his original guess.

However, it wasn't good to design a helmet and then run to Professor X and say to him, "Hey, bald guy, try to see if you can read my mind?"

If it succeeded, that was one thing; if it didn't, he would be exposing his own bottom line to others. If he were truly invaded then, it wouldn't be easy to use his fists to refuse, after all, he was the one who invited it.

Secondly, who was Professor X? Why would he cooperate with him? Was his face particularly big, or was the other party just bored?

However, even if he couldn't make a psychic protection helmet, trying to interpret the meaning of brainwaves was also a very good project. Starting by interpreting the human brain might still be too difficult. Then using a tiger's brain to practice might not be a bad start.

At least tigers didn't have such complex thoughts... probably.

Men and women were like different species; how could Henry use human thoughts to guess a tiger's ideas? He could only try and see.

And if he didn't hurry up and figure out a way to communicate with Katie, this little guy, having eaten and drunk enough, would spend every day full of energy chasing BB. It often chased BB until it ran out of power, and then hugged it and chewed on it.

Finally, the consequences of using plastic for the shell to save trouble appeared here.

The poor core robot, used as a teething tool, was always chewed up by Katie, and even when it rolled, it would get stuck by the shell. Henry had to repair it from time to time, otherwise, this little thing would be ruined.

Needless to say, he did it as soon as he thought of it. A brainwave device wasn't difficult; he just had to treat it as another language to interpret.

The most important thing was how to collect data correctly, and how to find homogeneity from the massive data matrix. To determine that a certain brainwave pattern represented a certain word, or a certain emotion.

Perhaps he could cooperate with smell, that is, the hormones produced by the body corresponding to emotions, to judge what kind of emotion a person was in.

The collection of this micro-scent was very difficult, no less so than brainwaves; both were collection targets easily disturbed by the environment.

If the sensitivity of the sensor was lowered, it was very likely that the correct information could not be collected. But if it was relatively increased, it was more easily disturbed by the outside world.

And all of this couldn't bypass using a computer to process a large amount of data. In order to speed up the research, Henry had to attack the computer equipment again, improving and upgrading it.

The goal wasn't the computing power that ordinary people thought of, but the data storage device, transmission method, and capacity, that is, the hard drive.

The mainstream hard drive of this era was the 5400 RPM IDE hard drive, that is, the ATA specification, with a capacity from tens of MB to hundreds of MB. If one pursued durability, large capacity, and high speed, they would go to purchase SCSI specification hard drives.

And because of the support of the SCSI interface, the use of multiple hard drives also developed various RAID methods, the so-called RAID.

And the SCSI interface wasn't just used for hard drives; it could be used for all peripheral devices except the CPU, motherboard, and memory. It mainly had an independent processor to share the CPU's functions to improve the overall processing efficiency of the computer.

As the CPU's frequency continued to increase and its performance continued to strengthen, the extra supplementary demand for SCSI devices would eventually be eliminated. There would even be situations where the speed of other computer peripheral devices couldn't keep up with the CPU's full-speed operation.

That was why the CPU frequency only developed to a certain stage before it stopped moving in the direction of "faster" and instead moved toward multi-core and multi-tasking, allowing computers to process more things at the same time.

However, the progress of hard drives was only upgraded from the IDE interface to the SATA interface. It wasn't until the appearance of solid-state drives that computer performance had a significant improvement in the user's perception.

Previously, when Henry was hand-crafting various computer devices, his main focus was on the three major components: CPU, motherboard, and memory, developing toward server-level expandability.

Everything else was bought off-the-shelf. Especially hard drives, floppy drives, and optical drives; these were peripheral devices that were relatively mature and didn't have much leapfrog progress.

The project he had previously focused on was assisting a group of enthusiasts on the internet to build the Linux ecosystem. Henry was like a worker adding bricks and tiles, while the engineer responsible for planning and directing was someone else.

And a major feature of Linux was finding ways to make some old computers run smoothly, extending the service life of these old computers.

So chasing computer performance was just satisfying a bit of the Kryptonian's sense of achievement. The things he hand-crafted were just better than off-the-shelf ones, and even better than other people's laboratory products.

Actually, the Linux system couldn't exert much performance.

But when it came to real practical application, Henry discovered that there were still parts that were holding him back overall. So, filling this short board was something he had to do.

It was just that Henry, who was in front of the workbench, dismantling and modifying the original hard drive, was thinking about the NAND_Flash technology that could be used for SSDs in later generations, wondering if he should make some solid-state drives.

BB, which had just been upgraded to a metal shell, was chased by Katie until it ran out of power and sprawled at his feet. Henry could only change the battery; now, wanting to let BB stay steadily on the charging station to charge was simply impossible.

Although there was no significant progress in reading the tiger's brainwaves, it was good news that this little guy already knew how to defecate in a fixed place. But it, full of energy, seemed unable to be satisfied with running and jumping in the house.

The house he rented from Old Gary could meet the needs of a small family, and the space was not small. But audio equipment, computer equipment, sofas, TVs, kitchen utensils, these things were also not few.

In order not to let those devices be destroyed by the little tiger, Henry naturally took some non-harmful protective measures. Basically, he made an isolation layer to protect them; what was chewed up or torn up would only be that isolation layer, which could be replaced.

But doing so also compressed Katie's activity space. This made Henry seriously consider whether to make something like a cat tree to make Katie's activities more three-dimensional.

Just when he was distracted by many things, the summoning bell at the black clinic in South Los Angeles rang again.

This was business coming again. Henry didn't say a word, changed into the tinkerer's attire, and set off again.
