Rocket Project Update

Ok, I have been working on this for a long time, and I'm still not done, but I wanted to make an update to show where I am at.

Change #1, Ignition System

I am using a Flyback Transformer as the ignition system. I had to rip apart a CRT monitor, and make a custom "driver" circuit to power the thing. It provides a nice 1 inch high voltage arc, much more capable at igniting my fuels than the ignition from a Utility Lighter I was using.

Here are some pictures to show you the layout.

IMG_0306

The Black thing at the bottom is the transformer, the circuit board is the driver I had to make, and the grey box at the top is a 250W ATX computer power supply, which I had to rig to make it power on.

Here is a picture of the arc it makes:

IMG_0336

Also as an improvement, the driver requires a transistor that gets hot very quickly as you use it. I decided to put it in a tub of mineral oil for cooling. It has shown that it lasts much longer than the heat sink I was using before. Here is a picture.IMG_0329

Last of all, here is a video of the arc.

Change #2, Electrolysis Setup

I have changed my electrolysis machine to make more accurate proportions of hydrogen and oxygen.

First off, let me explain the situation which prompted me to make the change. I had been running my Electrolysis Bucket for a while now doing several test runs. Well, I got to the point to where I was finally ready to do a full prototype rocket. I made enough gases to fill it up 75% of the way (which is what I want), and got it prepped to launch. Then nothing happened. It was full of only hydrogen. I devised a plan to make more accurate collection of the gasses.

Here is a diagram:

Electrolysis

With this design I collect the gases separately, then use a device I made to precisely fill the rockets.

So, Without further adieu, Pictures:

here is a picture of my bucket with the bottles in them.

IMG_0404

A close up of the electrode (my father in law made me these out of stainless steel). I was using graphite, but I found that the oxygen side (positive side) disintegrates too easily.

IMG_0405

picture of the gasses being collected.

IMG_0382

Ok, so I noticed something interesting. I tried a test fire, and I noticed that the explosion was a little lack-luster. I figured that the reason why was because electrolysis generates heat, and that the gases might be filled with water vapor. Later I realized that it was because I got my hydrogen and oxygen mixed up (because I forgot to label them) – so my proportions were waaay off (my mistake).

Solution: label the bottles, and refrigerate them. Refrigeration causes water to condense, purifying the gases.

Before refrigeration:

IMG_0409 IMG_0410

After Refrigeration: as you can see, the water vapor has condensed onto the sides of the bottle.

IMG_0415 IMG_0416

So, how do we get the gases into the rocket?

This little device:

IMG_0433

I made it out of two bottle caps and some tubing. You will notice that the ends are offset in length from each other – this is done in a specific way to cause gas to go through one tube, and water to run through the other.

Directions: fill a bottle (the rocket) completely with water, connect it to the green end. Then take the bottle with the gas and connect it to the red side. The last step is to flip the rocket up in the air, above the other bottle, and the fuel will automatically start transferring.

I don’t have a video of this yet, but I am quite proud of it.

Change #3, The Launch pad

So, I noticed that I needed a new launching method. I needed to ensure that my rockets will aim straight before it has a chance to start spinning (from the angled fins). So, here is my original launch pad:

IMG_0391

You will notice that there is no provision if the rocket doesn’t initially fire straight.

So, what I walked around Lowes looking for launch pad ideas. I looked at PVC, but it was waaaay to expensive, so I came up with a novel idea:

IMG_0452

I bought two 96 cent pieces of wood, cut them in half, and then taped them to a bottle filled with water. I made it so that it tapers out at the top, so that it has less resistance to the rocket. Pretty good solution for about $2.00

Ok, so what would a rocket project be without failures?

Who Turned Out the Lights?

IMG_0296 I will let you draw a your own conclusions as to what is going on here.

Yes, I am taking apart a CFL light. It provides a high voltage charge (which is what “energizes” the light).

So, I made a rig to test it:

IMG_0303

So, results: as soon as I went to arc it, it fried :(

A Bad Case of Gas

So, after just making a rocket with my electrolysis bucket, I got it ready to fire.

The rocket filling with hydrogen (and supposedly oxygen).

IMG_0229

So, without further adieu, The video.

You probably cannot tell immediately, but I am using the flyback to make a really nice arc in there, but the rocket did not fly. After some investigation, I found that the rocket was full of only hydrogen. It did not go off at all.

First Successful Hydrogen Rocket

So, I finally got it all together on the electrolysis side, and I got a rocket ready.

here is a picture of the rocket:

IMG_0390

this thing was beautiful!

so I eagerly set it on the pad, ready for launch:

The rocket after launch:

IMG_0399

And one more, Just for kicks

this is an Alcohol rocket I made to test out a new nozzle I designed. I think what happened is that the hole of the nozzle was closed off enough to make the bottle expand when it fired. Because the bottle expanded, it got caught in the launch pad. My ideas still need improving.

And that’s it folks.

Rocket Project

Hello everyone, it's been a while.
I wanted to show some pictures of the rocket project I am working on.
First, lemme explain how it works.

This is an Oxyhydrogen (H2 and O2) powered rocket.

So, schematic time:
By running DC current
through water (with an electrolyte, such at table salt or baking soda) the water will separate into Hydrogen and Oxygen in a 2 to 1 ratio. (see Electrolysis of water)
The H2 and O2 gas generated is then piped to the inside of the rocket.
The incoming gas replaces the water in the rocket until it is about 60-70% full of fuel.
The rocket is then ignited by putting two electrodes into the gas mixture and making a spark.
The gases explode, causing the water to be spewed out violently. This is how we obtain thrust for the rocket.

So, my implementation (so far - still a work in progress)

The Electrolysis Rig
Parts:
  • Power: I bought a bridge rectifier from Radioshack that converts 120VAC to 170VDC.
  • Rig: I bought a bucket from Lowes (and a lid - yes, they sell it separately), with some tubing.
  • Electrodes: The key element is a Gouging Rod I obtained - carbon is the ideal electrode because it doesn't corrode. You can also use Stainless steel rods (or screws), but I discourage this because there is a potential for releasing Chromium (which is poisonous).
  • Electrolyte: I used Table Salt, but I found that Baking Soda worked better. Baking soda is cleaner and conducts better.
Preparation:
I cut my carbon rod in half, and then soldered wires to each half (be sure to use wire colors to denote one as positive and one as negative).
I drilled two holes on opposite sides of the bucket for the electrodes. I then drilled a hole in the lid for the tubing.
I epoxied the carbon rods in place on either side, and then epoxied the tube in place on the lid. I made sure that the end of the tube (that connects to the lid) was as close to the Lid as possible
(this is important).
it is important to run electrolysis in the bucket to erode the copper on the carbon rods before you use it for the first time - on the positive lead, oxygen is produced, causing the copper to oxidize, or rust, decreasing the amount of Oxygen produced (i.e. not good).

Use:
Fill the entire bucket with distilled water. Fill the tube with water. Connect the power supply to the electrodes. Plug in the power supply. Slowly add the electrolyte (baking soda) to allow conductivity - be careful not to add too much, as this will cause the circuit to arc.

The Rocket
Preparation:
I bought some 2L orange soda from Publix. I used some CD Jewel-boxes to make some fins for the rocket. The cap of the soda, I drilled a hole big enough for the tube, but just big enough for a snug fit - this needs to be able to pass water over the outside of the tube.
I also bought a utility lighter, not for lighting anything, per say, but for the electronic igniter. I removed the igniter and then soldered it to some cat5 cable for an extension.

Use:
fill the rocket entirely with water, insert the tube, start the electrolysis (this will push fuel through the tube, and then into the rocket). When the bottle is filled mostly with gas, remove the tube and insert the cat5 cable for ignition (you may want to put some tape over the hole temporarily).

move back and click the ignition.


Just so you know, I haven't gotten to this point yet, but I have done preliminary tests, and the ignition works. My "rocket" went 2 feet off the ground (I think I had too much water in it, plus the bottle didn't really hold up the pressure).

So, pictures:
This first picture is just a good view of the whole thing.














This one is of the top of the lid, where I epoxied the tube to.














this one is of where the electrodes are placed in the side of the bucket and a wire is soldered on.














Here is my rocket, with a hole in the cap and fin's on.














And finally, this video is of a preliminary test where I am lighting some captured Hydrogen and Oxygen.

Whatever happened to the days when...

What ever happened to the days when occupations had a reputable name to them?
here are some of the connotations I now think of (not that I am saying that I believe this, but apparently somewhere in my memory these associations have been implanted):

Businessman: bent on screwing you out of money
Politician: bent on screwing the population out of rights
Milkman: bent on screwing your wife

there are many other reputable occupations I could name, but the milkman is a good example. Granted, there are no milkmen anymore, from what I could tell it was a decent job that held respect among the community. Because of the decline in demand for fresh delivered dairy products, the occupation is just about extinct. A remnant from this extinction is the joke that a fathers children aren't really his, but are actually the milkman's. I will not investigate how this joke came to be, but just because of rumors like that the milkman's purity is now forever tainted.

Lets move on to the politicians. I did not know them, but the founding fathers (in my mental image) were politicians to look up to; they fought for what's right. And somehow the concept of a politician has been drug through the mud. Now, I know a few politicians who are probably rightfully called pigs or snakes, but really this is a small handful. I have met other politicians who have been wonderful and upstanding in all they do. So how did politicians get such a bad rap? because a handful of politicians were crooked, and people over generalize.

Lets move on to businessmen. This is probably the one that irks me the most. Think GM, World Bank, Enron, Bernie Madoff and others. What is the general opinion of these companies? very poorly run, or a company that survives off of cheating. Organizations and individuals have made the name businessman a little tainted. I even have an experience where a electronics repair person tried to fix an LCD monitor I had.
On his window was a Better Business Bureau member sticker, and his place looked a lot like the repair shop I used to work for. I paid $60, and got my monitor back in 2 weeks. The problem was not fixed at all. I'm gracious and thought "maybe the guy didn't catch it all". so I brought it back to him and he said he would fix it at no extra charge. About 2 months later, I actually stopped by his place, because he hadn't called me. he said it would be ready the next day. I showed up the next day, picked up my monitor, and when I brought it home to plug it in it was still exhibiting the same symptoms as before. Granted, I probably should have tried to get my money back, but I didn't want to bother. So, based on this experience a couple of false conclusions can easily be made. 1) Electronic repairmen cannot be trusted to fix anything, 2) If Better Business Bureau is advertised then the establishment cannot be trusted (shouldn't a business rely on it's own rapport to maintain credibility?) and 3) Businessmen in general are only concerned about how much money they can make.

So, why am I ranting about this? Well frankly I don't like that everyones credibility has gone out the window because someone else in their respective field has ruined their name. I don't like being told that I can't trust companies because they are "Greedy," I don't like being told not to trust politicians because they are "Crooked," and as for the milkman, well I don't know any milkmen so I really can't say much on that.
I guess what I am really ranting about is the stupid overgeneralizations that people make about, well just about anything. I trust most companies to be good and frugal (otherwise how would they be in business?), I trust that most politicians honor their word (otherwise how would anyone get re-elected or even have a rapport to get elected in the first place), I trust that most milkmen were honest people (again, not that I know any).

anyways, thats my rant and I'm sticking to it.

The Temple

We went to the Birmingham Alabama temple Saturday for my brothers Endowment. It was awesome. I always love the feeling of love and peace you can get by attending the temple. It seems as though life's annoyances have taken a slight back-burner and the simplicity of life has returned.

My brother will be going on a mission for our church to Ogden Utah. I am way excited for him because I served in the Tennessee Nashville Mission (southern speaking). I would say that my mission is what made me a man (or should I say Mann). I am so grateful for the countless lessons I learned about myself, about God, about others; it totally changed my life. It taught me to be more patient, more loving, and more understanding. I am anxious to see what changes it will bring in Brad's life.

Well, tonight will be a short entry because I have school tomorrow (and it's 11:15 pm).
Goodnight Neverland.

An Ode to My Wife

I just looked up the definition of ode, and found out that it's supposed to be a poem. I don't write poems, therefore this ode will be poem-less (or perhaps oderless -- yes, I know it's spelled odorless).

I just wanted to publicly say how much I appreciate my wife. Everyday she amazes me in her stoutness of character. If she were a pioneer, she would make it for sure.

Words do not describe well enough how I feel for my wife. Sadly the word love has so many uses. I love cheese. I love to tango. I love my brother. All these are separate derivatives of the word, but the only one that doesn't seem like the word is suitable enough is: I love my wife. Sure you see it on a bumper sticker occasionally, and you casually say I love you to your spouse every time you are ending a phone conversation, but what about the times when you really want to express how you feel?

I guess the only good way to emphasize the phrase "I love you" is to couple it with answering "why?"

I would like to answer these, because 1) I know my wife will read this eventually (hopefully evoking a very feminine "awwwww"), and 2) I want the world to know how much she means to me too.

I find that it is easier to answer the question of why by using words as if I were speaking to her. So, for those of you who are not my wife, just read for the fun of it (I'll even give you permission to wish I was writing to you).

I love you because you are my best friend. You have cried with me in my darkest hours, and have laughed with me in the happiest. You have been there for me since the time that I met you (even when we were "just friends") even when any other friendship would probably not endure.

I love you because you are dependable (sounds like a quality on a resume). By dependable I mean that I can trust you with anything. I can depend on your advice, on your help, on your faith in me. I love that I have someone who almost always knows what to do in every situation.

I love you because you are patient. I know you are probably thinking "yeah right, I loose it with Natalie almost everyday," but you really do... so much more than me. I can think of a ton of examples, and then it would be a test of your patience just to hear them all. Mostly, you are patient with me. When I screw up, you forgive me. When I decide that my way is right, you are patient with me to wait until I come back to you and tell you that your way is better (by the way -- guys, if you haven't already figured it out, for some reason I cannot explain women have this far surpassing wisdom that is uncomprehensible by men, and only when a man figures this out will he truly be wise). I find that your advice is so important to me. It has always led me in the right direction.

I laugh at our silly fights, because they show that no matter how bad it gets we will always be there for each other. I remember when you decided to make chocolate milk. You had poured in so much at the bottom that it made a swirly effect on the sides of the glass. I made gesture that I wanted to see your glass and you recoiled defensively (never take chocolate milk away from a woman with cravings). The most rediculous argument ensued. We argued about chocolate milk and about why I should be able to see the chocolate milk that you made because it looked cool and yadda yadda yadda. I remember that after this fight, we just laughed at each other for having the stupidest argument ever. This is why I love you, because you don't let the inane things ruffle your feathers.

I love you because you are beautiful. Rooms light up when you walk in (or maybe there is a power surge in the electrical circuits -- then maybe you're just electrifying). The way you move is full of grace and beauty. Your hair is soft. Your legs are shapely and the skin so velvety. Your face melts my heart. Your face is where I find you most beautiful. I could look into your eyes forever and not get tired (like a staring match). I love to put my hand on the side of your face to feel you lean in and stroke my palm with your cheek. I think the clothes you wear make you look very attractive (however I will already admit (not to discredit this statement) that I am a little biased).

I love you because you are an excellent mother. I see the way Natalie adores you and goes to you. Sometimes I am jealous (other times I'm not -- like when she's throwing a tantrum). I see how much she loves you, even though she cannot say it. I see so much of your caring nature in her. I cannot think of a better woman to help raise my children than you. I am amazed at your capacity to love others in the way you do.

I will take that last sentence and start with it rephrased: I loved your capacity to love others. I think this is your most defining characteristic. To see the love you have for your mother and father, I feel sometimes as if I am in the presence of an angel. You have always shown the greatest love and consideration for others. I am so glad that I married you because I get to be a primary benefactor. Your willingness to serve your mom and dad like you have in the past years (2 years that I've witnessed, and all your life as far as I know) is remarkable. It speaks volumes about you. I feel that I owe your parents a great thank you for producing such a wonderful daughter.

I know I can go on forever telling you reason after reason why I love you, but I take comfort in the fact that you already know. I take comfort because you love me too (which is the most priceless thing I have ever found on this earth). I love you Melanie. I just wanted you (and everybody else) to know that.

Love,
Your Mann (and for those who are not my wife, you can omit this salutation)

The Emperors Club

So Mel and I watched The Emperors Club tonight ( http://www.imdb.com/title/tt0283530/ ) a movie about a School teacher trying to teach a deviant kid. One of the subjects of the movie is how Schools aren't supposed to teach morals, but just teach facts. I'm sitting here thinking about it, and I am asking myself why.
So I thought about what could have possibly caused rise to schools becoming less and less about character and more about just plain old facts. In the movie, the teacher goes to the boys father (a US Senator) to talk to him about his sons poor performance. The teacher makes a remark about how his classroom is to shape young minds, but that the senators son is refusing to be shaped, to which the senator responds that the teacher is not supposed to shape his son, "leave the shaping to me" he says.
So shaping is to be done by parents, to this I agree wholeheartedly. It is the primary role of the parents to teach morality, honesty, integrity (and a bunch more -itys). But I wonder if there is a rising problem: what about parents who don't care. These students may not receive the life-education that's needed because their parents are either not there (physically or mentally), or the parents simply don't care.
So, from what I observe, it seems as though there is less lessons on character in schools (because schools say it's the parents job) and more and more parents not doing their job of schooling their kids on moral issues. So rhetorically speaking: who teaches these kids how to be good people? I don't have the answer, I'm a nobody, but I have opinions and ideas.
I understand that there are some subjects that cannot be discussed in school because of the wide interpretations of whats right and wrong. Hey, there's a funny though, right and wrong are words that have such vast meaning. Is this the right religion? Is it right for me to become a Fireman? Is it right to say that today is Sunday? Should I choose the Busch brand of baked beans, or the store brand? I think you get the point that Right and Wrong have very sliding scales of ambiguity depending on the context in question. Perhaps schools form their curriculum solely on those truths that have little to no ambiguity: is "2+2 = 4" a truth bearing statement?
With this in mind, I do begin to wonder though, if there are not universal moral truths that can still be taught while staying in the realm of little ambiguity. Perhaps the subjects of Honesty, Integrity, Truthfulness can still be taught, not just tested. I know that there is some teaching of these principles, for example honesty is used during tests, one is punished for cheating (read my post about typing class), but what I am wondering is if more can be done.
The books I am reading for English right now have messages, but really little moral compass as to right or wrong (quite possibly because the authors were mostly questioning what that is). What about other subjects: Math (well in that you have to be exact, but I still don't see much in moral lessons), Science (still don't see it), Social Studies (now this might have something, but most teachers try to steer clear of interpreting the past, they just try to present it accurately), Gym (I hated Gym, but it has potential to teach good sportsmanship).
I think overall the school system is a little weaker in moral standards that what it can be (look at Sex ED, talk about a joke for morals). What if school systems tried to incorporate books that actually have a universally taught good moral (like a person who is honest and hardworking gets ahead in business - oh wait, who am I kidding, crap like that is boring). What about intense studies of history's examples of how good moral decisions brought good outcome.
Maybe I am asking the very thing that parents argued against in the first place, who knows. I don't have an answer, I'm just thinking that shrugging behind the fact that you have to make absolutely everyone happy is a little counterproductive.

I do have a question though: Has anyone made a deep study of Love and it's effect on an individual and the people around this individual. I'll bet you that there would be boat loads of good lessons there (aside from the religious ones).

Anyways, I would like to hear some feedback (mom, I know you've got some).

So what to post tonight?

I can't think of much to post... Any suggestions?

So, today I was sitting in the local library today working on getting my English assignment read – The Awakening by Kate Chopin. Luckily for me a few days earlier I found an open license audio version of the book online. So I set all up with my laptop, headphones, and the book… queued the files up and hit play. About 1 minute in, I’m starting to pick up on the weird cadence in the woman’s voice. She intonates words in the middle of the sentence as if it were the end of the sentence. Also, she randomly makes the pause after a sentence extremely long, suggesting to one not reading along that it is the end of a paragraph. About 5 minutes in, I’m having a hard time picking up on what’s going on (which I don’t think is so much the fault of the faulty orator as it is the author who likes to be descriptive with everything). About 10 minutes in I am beginning to lose it. I message my wife about how bad things are, and chat about nonsense. I muscle to 30 minutes. After realizing that I was simply not able to pay attention (not for a lack of trying) because of overload of non-necessary information (or at least what I deem necessary) I finally relinquish the audio copy and dart for sparknotes (online free version of cliff-notes). Also, luckily for me at this time my wife called and said that I needed to come home to help her with something (yaaaaaay, no more torture).

Do English teachers really pick out the worst books that they know of? Is it like some sort of sick revenge for the crappy novels that they were forced to stomach during their college years? Or maybe it’s that I just lucked out and got the guy who reads this kind of crap because he likes it and has a strong feeling that everyone else should love it too (8 novels worth of pain). That last argument I understand a little. I mean, I love techno, so much that I want other to listen to it. Even when prompted with the chance, I share it with whomever I can; however I have a feeling that this is different. You see, I don’t force people to listen to 9 hours of trance CD’s if I can tell within the first 10 minutes that they don’t like it. English is not my major, and ancient American literature is definitely not something I am seeking to develop an appreciation for. Sure it was pivotal stuff for its time, but that was eons ago, no one cares now (lemme rephrase: very few people care now).

Alas I digress.

Did I ever tell you about the time that I failed keyboarding class? Well, lemme tell you about it (can you tell that I just thought of it while I was writing?). So the year was 1997 (high school sophomore, first semester about to become the second), I was talking to my friends at lunch about what to take next semester. We talked about different things, and one of my friends pipes up and says “You know what you need to do, take an easy class. You know something that will get you an easy A to get that GPA up, you know stuff like keyboarding. I took it last semester and it was a breeze. All you do is type all day.” So, on that recommendation I opted to take keyboarding. Sadly, for the sake of trying to be accurate, I cannot remember the teachers name; all I know is that it started with a W.
The first day of class we sat at assigned seats, but the computers were off. On the board was written “What is your name? How experienced are you with typing? What are your goals to improve? What do you hope to get out of this class?” You know, the getting-to-assess you kinda thing (not quite as good as getting-to-know-you). So I fill out my answers and hand it in. The next day, she had us fill out a worksheet (I can’t remember what it was about, but I do remember saying to myself “this is lame”). The next day (still not on the computer) she has us fill out another worksheet (probably some kind of assessment to see how well you would do in a position as a typist, gross). So I decide to write the teacher a note. I don’t put my name on it, but I basically say that this is an incredibly lame class that the computers aren’t even on, and that we aren’t even typing. The next day, she starts us on the computers… but at the end of class she calls me over to her desk. She said that she could tell it was me who wrote the note by my handwriting. I think she did that because she wanted more to respond to the cockiness that was in the letter.
Just to let you know the computers we were on were old pieces of dirt that were running Windows 3.11 (yup, that’s windows for workgroups); a great product for its day, but not so much when the computer lab across the hall had Windows 95, and my computer at home had Windows 98 (talk about all the other computers just taunting you because you were using old school junk). Fast forward to a few weeks later and you arrive at a pivotal moment in my experience with this class. This was a special day, because the teacher went on vacation and there was a sub. At this point I had made friends with a few people in class. I’m going to break for a moment and tell you about something that a famous hacker said. His name was Kevin Mitnick, he is probably the most well known hacker out there. He eluded the FBI for 10 or so years and was able to pull a bunch of crazy stuff. I watched an interview with him after he was released from prison (probably around 2002 or so). He said that the real trick to how he was able to pull all that he did and elude being caught was something he called “Social Networking” (which in this context, means to take advantage of the trusting nature of others for your own purposes). That being said, I do not say that what I did (as I will tell you shortly) is my finest hour. So I made friends with people in class, and there was a sub. I convinced the sub that my computer was broken and that I needed to move to a different computer (right next to one of the girls I had befriended). So, I got on the computer and instead of doing my work, I poked around (remember, these are Win 3.11 machines, whoopee). Well, I have never worked with the networking features of windows 3.1 before, but I soon found them, and also found that I could access several computers. So I looked through the list and found the computer for the girl next to me. I clicked on that and was shown all the files on her floppy drive (the place where we stored our files that we typed to turn in). Now, this had taken a majority of the class period, so I needed to have the current days work done (as I had been playing instead of typing), so I asked the girl next to me if I could copy her file (like any gentleman would) so that I had something to show for. I copied the files and put my name at the top of the file, and turned in my disk. It was a weekend, so when I came back that Monday I was met by Mrs. W. and one of the other school officials. He took me to his office which was conveniently across the hall. She accused me of cheating, and like a good boy I admitted to it. He asked me why I did it, and I just said that I did it out of curiosity, explaining how I did it. It wasn’t until later that I found out that she used a program and found that I had copied my friends work. I was sentenced to one day in ISS (in school suspension). Now one day may not seem much to some of you, but for someone who had never been in ISS before, this was horrible. You have to sit in there doing your schoolwork completely silent, staring at the wall, in a poorly lit room that looked like it used to be part of the locker rooms (and smelled like it too). Lucky for me, the day I went in, they had a pep-rally, which meant that I only had to be in half the day.
So, summing things up, I went to the final exam for the class, walking in with a 46%, and knowing that all hopes of even passing were blasted, I tried my best anyways. You know, this is one of those experiences that have taught me something about myself: I hate keyboarding, and I should be taking a computer class. So the next year I took AP computer science and passed with a 5 (which is the best you can score).
Lesson learned: go for what you really want, but try to be ethical getting there.

Wow, I guess this was a long post after all.
