This week we needed to string together a program using all the sensors. With all the programing we did the first week it didn’t take us to long. We got the program up and running the first day. There was probably alot more we could of done with the bot, but once we got the assignment done we ran it through a couple of times and showed it to Dr. Brown and class was pretty much over. Icame to lab on Weds but had to leave early to pick up one of my kids from school. The bot seems like a cool toy, but didn’t really hold my attention like I thought it would. I do think my kids would probably like it. It just wasn’t my thing.
This week was pretty interesing. We worked on a different sensor each day working out the kinks till they worked smooth. Having the bot follow the track on Friday was the most interesting of the sensors. The hardest part was getting the bot to turn around a certain distance, although after a few adjustments the turn was very smooth. We tried stringing a few of the sensors together to make a longer program, which worked out well. We got the bot to go foward turn around 180 say goodbye do another 180 and race away. Then we added the bump sensor so that it would turn around when bumped and race the other way. The sensor that looks like eyes didn’t want to work at 1st then we adjusted the distance and it worked fine. All in all not a bad toy.
Thoughts concerning computer hacking, viruses and other security-related issues. Well I think it is pretty lousy for someone to mess with the viruses and such. We work hard to get a computer we can afford and someone just steps in and messes with it. I agree with the law, send them to jail until they learn to respect peoples property. Phone phreaking wouldn’t bother me as it is not personal and it doesn’t damage the equipment. I’d love to be able to do some of these things, but only so I can have the knowledge and ability to combat the viruses. Knowing a computer well enough to be able to go in and change what I want would be cool, but only to experiment on my own equipment not to destroy someone elses’. Hacking for the sake of hacking might be fun, but what is the point of viruses in the world. Can they be used for anything other than destruction?
Working with scratch is cute and fun. My kids might like this, but I’m just not the creative type. Even though this is interesting it is just not my thing. Hopefully the Bat chasing the Cat show will be good enough as that is about the limit of my imagination. As for the talk by Randy Pausch I was out sick that day so I missed the whole thing.
Well I haven’t figured alot of this out yet. The HTML would appear to be the hardest part of the class so far. I’m working on it to little to catch on, I think. I’ve got a couple of paragraphs written up and saved on notepad and I’m going to add some pics soon. I’m writing about Pomeranians as I have two and think they make excellent pets. I used to raise them until someone took my male. Can’t breed dogs when all you have are two females LOL. I have been reading my notes and will add columns to my page so that I can put pics on it. Also I will add some sort of background. I see how to do these, I just need to play around with it so that I can get the page up. I do need to find out how to add a background as my notes only tell me how to add a background color not a background pic. I go on the discussion board and see if someone can help me there.
Let me see machine code, assembly language and the Assembly Language Simulator all three were interesting. Machine code wasn’t bad although using the simulator was much more interesting. Same for assembly language it was all right to work with as long as I have the little chart that tells me how to switch back and forth between machine code and assembly language. I spent at least two or three hours on the Simulator getting it to work right and found it very interesting figuring out how it worked. I did have to ask for help once but if I had asked sooner I could have saved myself at least an hour of work. When it comes down to paper work with the machine code or the assembly language and the Simulator I would choose the simulator any day. I also enjoyed the videos on Friday I was expecting them to be boring but they weren’t. Steve Jobs had some interesting stories and the interaction between Jobs and Gates in the interview was entertaining.
I chose my computer parts for my son who likes to play games online, except for the trackman mouse and the ergo keyboard I just like those. I don’t know enough about computers to really choose the parts so I hope I chose well. I did try to get parts that would work well with gaming by reading the other available blogs. Then I got my list of steps from watching the two available videos. Charity’s blog was especially helpful. Other than that I got on newegg.com and did most of my research on there by reading the reviews for each part I looked at. It took a few hours but I think I have some good parts. Altogether my PC cost $1910.86.
To put together my computer using a metal table as the video suggested:
1st I lock the CPU into the Motherboard
2nd Latch on the CPU Cooler, and plug in cord.
3rd Push memory into RAM space.
4th Install back plate
5th Position Motherboard properly, screw in.
6th Put in Harddrive, screw in and plug it in.
7th Remove panel and install DVD drive. Screw into place then plug in.
8th Install USB ports and plug them in.
9th Install Power supply and plug it in.
10th Install Graphics card & attach to case with screw.
11th Snap in sound card & attach with screw.
12th Make sure everything is plugged in.
13th Turn it on, install OS, and hope for the best.

Hey this is Deb Lewis I really liked this week in class. The binary was a lot easier than I thought it would be. I don’t know how to make this into two paragraphs. Going from binary to decimal and back again was neat. I thought it would be much harder. Now the hexadecimal was a bit more challenging and octal must be real bad since it wasn’t even described in class. But since Mr Brown said we won’t be using those two I guess it doesn’t matter. I’ve been printing out the comic book which makes it alot easier to read. Not to mention that I can read it anywhere, I don’t have to be at my computer.
