Socials is over, and how fast time flies by when you are having fun… To give you more of a visual, I have included notes in my PowerPoint that I presented in class on Wednesday. So when you click on the link, just click on notes on the bottom right hand corner and you will see an explanation of each slide, which is also kind of my script for the presentation, altered a bit.

Two weeks have gone by since my first post, and it was just a blur. For the first two weeks, I was just planning to learn about the Raspberry Pi in general, like its hardware specifications, Linux (Raspbian on the Pi) and a bit of Linux command prompt. My main source of information was two books published by the Makezine, and I find them to be very insightful, current and accurate. The only bad thing is that it is going very fast and lacks explanation in some parts, and I have to read more than twice to understand a shell command in Linux, for example. I did encounter some obstacles, like finals that delayed my process. To admit it, I didn’t do as much as I planned to do, and I think it teaches me to consider in external factors when planning a schedule. Below is a visual I made that contains the basic facts I now know about the Raspberry Pi. Linux commands that I learned are not shown because I couldn’t find a way to display them.
My mentor (I only know his Chinese name, I forgot to ask for English name) and I have set a schedule to meet after church hours, as he goes to the same church as I am. He has given me his CRC last Sunday, but I had forgotten to hand it in. Our last formal discussion was the Sunday after my first in-depth post, so two weeks ago. It was focused on the outlook of my final project, and some difficulties that I might have achieving them. It was more of a fact based talk, rather than opinion based, so there wasn’t a lot of point we could agree, or disagree on. I had just read to chapter 2 in the book then, but I did read Ms. Mulder’s summery on her blog post.
How to Agree: Most of our discussion was in unison, like how we discussed the number of time I should spend on this topic, the ideas that he proposed to make my project work. There was one time when he mentioned a new point about how a car could sense and avoid incoming obstacles that really appealed to me, and its logic was better than my old algorithm. Something that I didn’t agree with entirely at first was that my mentor mentioned that the Python language is easy. The same thing was said by my dad after. But to a newbie like me, it was hard. It was like learning French from English is easier than knowing no language and starting to learn a new one, word by word. I recognized that when my mentor said that because he knows multiple languages and knowing the structure of languages, Python is easy to him. Another influencing factor is that it could be my own conception that is wrong. Everything is hard before you learn it. I appeared to me to be a sweeping generalization. So I agreed that Python is a relatively easy language compared to others (agree with part of statement), in the end, even though it still seemed hard for me.
How to Disagree: So for the example of Python is easy mentioned above, I disagreed with part of the statement and politely brought it up because of the experience different between my mentor and me, so I could only say, Python is a comparatively easy language to people who knows other languages. Besides that, I don’t think there was any other disagreements.
How to Differ: Now that I remember, one difference that we encountered was how the car should react when it senses an obstacle. I thought it should turn right, turn left, turn left and turn right again, so it would go back on track. But my mentor thought that it would be better for the car to stop and turn around to go back the way it came from. In the end, we reached an agreement that this is based on the road and the obstacles, and that it all depends on the outcomes and functions that we want the car to reach.

During my long life as a philosopher, writer and playwright, I have stood on the far edge of human thinkers with my ingenious ideas. I wrote about the ideal world, with more reason behind our actions, less tradition like religion. Other countries respected me, trusted me for my work against tyranny, bigotry and cruelty, but France, you have always been hesitant. Looking back at this whole “revolution”, I see that you have strayed from the right path. Look at what that guy Robespierre did, committing murder in the name of public safety. And guess why he did that, gee, I wonder if that’s because he is hugely influenced by that creature named Rousseau? In any case, if you, had listened, all of this bloodshed and savagery could not have happened, and the misery you had forced upon your people would be lesser. – Voltaire, past revolution
We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology. – Carl Sagan
In today’s world, technology has become an indispensable part of our lives, and for all the reasons, it improves our lives beyond what is previously imaginable. Our tech keeps evolving, and it is to the point now that we don’t need to
think about “how to use it” when we have an IPhone in our hands. The creator of Raspberry Pi, a mini single board computer and also the object of my studies, noticed how people
started to have less knowledge of programming languages. As a result, he made the Raspi, aimed towards teaching and inspiring an interest of computing in children, but is also commonly used by D-I-Yers because of its low cost and ease of access. As someone who has always loved the idea of learning a programming language, plus making stuff that improves my life, I think there couldn’t have been a better project to do than learning the dynamics of the Raspberry Pi and to make a cool “smart” project with it.
We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology. – Carl Sagan
When I say will learn about the Raspi, specifically, I mean I will learn about Python programming and electronics, which are the basis of creating anything spectacular with the Raspi. It is like how learning computer usually means learning to use Word and send emails. Computers are used for these things, and while the Raspi can do word processing and send emails, it is only in its best in a project, programmed to your will.
My project will focus on getting the technical knowledge down, like learning electronics, and then I will start to build my final project, a car that follows lines and knows to avoid obstacles in its path.
The final project, a self-driving car, is going to take some form of artificial intelligence. In computer science, a perfect “intelligent” machine is a flexible agent that perceives the environment and takes actions to maximize its chance of success at a goal. I plan for the car to be able to sense obstacles in its way, and thorough its “intelligence”, it will do some action to avoid it and keep going down the track it is given.

I chose this topic because my dad is a computer engineer, and he had just recently discovered the Raspi. He bought one to serve as a smart TV box that can watch YouTube or browse the web. I had also read about a major advancement in one of the companies experimenting with the concept of self-driving cars. I thought then, to combine them together to make one of those cars you see in science fairs. View my schedule of next two months. I have changed my schedule in the contract due to incorrect calculations of how long the project is going to last.
My mentor is someone in my church whom I just discovered to have studied computers. He even knows about the Raspberry Pi, and that would be really, really helpful. Before, I was going to settle for someone who know Python, and there should be many of them, but now I can get help on the electronics sections as well. I had asked him to maybe give me some information about his schooling or experience, but he hasn’t replied me yet, so I could probably bring this up next post.
I hope to be able to put together more and more advanced projects using the Pi after In-depth project, in the fields of home automation and simple artificial intelligence, because my proposed final project is not a very “useful” thing considering that it is a toy. So I will still have a long way to go after the project is finished.
Refer to this page if you don’t get what is happening or why I am Voltaire from the French Revolution.
Hear ye, hear ye! I am François-Marie Arouet, or Voltaire, a French writer and philosopher. Here I present “Free Thoughts on the Proceedings of the Monarchy!”…
I am writing this pamphlet in comment of the situation right now. Among all this debating and rhetoric, I want to remind you all of what I have said, that monarchy, is indeed, the best way of government for a country as large as France. It would be just too time consuming to fully consult the opinions of the people with what ways of communication we have, for instance. Quoting myself:
“I would rather obey a fine lion, much stronger than myself, than two hundred rats of my own species.”
Heed not the rabble who scream revolution, they had not the best plan for you. Chaos and bloodshed are not a solution, don’t let them led you astray. This monarch does not speak for me, nor does all these poor and dumb men. I pray the King will confess all sins, at last, at last. Inspired by Samuel Seabury. I see the injustice, clerical abuses, prejudice, and fanaticism in France, and don’t get me wrong, I am not saying our monarchs are doing just fine. They are not, as a matter of fact, as you readers may have noticed. The thing that we need to do now, is to try to break the barriers of superstition and let reason guide us into a world with better policies like the ones in England (English religious tolerance and freedom of speech). What we will have, in the end, is an enlightened monarchy, full of wise men and led by reason instead of traditions like what the Church had imposed us with.
My obstacle could be you, reading this paragraph. Don’t be persuaded by rats in our society, and if you are one of them yourself, think of the idea of a revolution against one of the most powerful nation in the world. Where will you get your guns, or would you settle for a fork? What comes after the revolution, do you think that all you farmers and bakers can honestly set up a society?
Towards this issue, I am doing what I could to pass my ideas on to more and more people. During my stay in the King’s court, he found that he is already enlightened, just too authoritarian. I encourage fellow writers to speak up, not to harshly, and to influence the court if not the King.
