HVAC system are awesome.

1 week ago by engineerisaac 0 commments 26 Views

So my air conditioner stopped getting as cold as it once did. I started doing a ton of research on how thermodynamics worked. How expansion valves worked and how the whole system worked in general. Turns out this shit is pure magic. And most air conditioners can only handle a 3 to 2 degree differential. But the amazing part of why they work is they can maintain that 3 degree shift constantly.

Meaning that if your house is on a loop, Like 99% of the homes across the US. Then if your house is at 74 and you have a constant -3 Differential then in enough time your temperature will hit 71 if the loop continues. And then can continue to drop unless some type of thermostatic system is put in place.

Lets put this into easy perspective. The most complex and expensive part with all the moving parts. Chills outside your home in the compressor and expansion coil. It is basically a sealed pump and a radiator. Its hooked to a switch that turns it on and off along with a fan. THATS IT.

Then once activated it begins to take this misty like substrate and smashes it into a compressor so that way its a liquid like format. It travels inside your home and at this point the chemical is luke warm until it hits what is called a expansion valve. Now here is where the magic happens. due to the chemical CFC in the line that is in liquid it gets forced into a small nozzle and then the moment that fluid escapes that nozzle into a larger side chamber it reacts causing a cooling effect.

The cooled liquid then travels through another radiator called the condensing coil. It then absorbs all the heat energy from your home and stores it into a ever expanding format to where it turns back into a mist and runs at higher pressures back to the outside expansion coil where it takes all that energy it absorbs and expells it outside. "This is why your outside condenser blows hot air out." And then repeats the cycle.

Now when a HVAC comes to your home they bring a manifold that they attach to your system. This device measures pressures against the 2 sides of the loop to make sure its within the nominal levels.

While we as customers cannot touch the CFC chemical unless we become EPA certified. We can however Measure the differential to be sure our device is working by putting a temperature read out in the return and exhaust of the system.

I set this up with my automation system to get a reading of whats going on.


My plan is to write a logging system that will measure this change constantly.

My Self Driving Car Adventures

2 weeks ago by engineerisaac 0 commments 57 Views

This is today by Nvidia.


Something had to spark a need to drive without driving. My desire for that started in 2005 With a honda civic.


It initially was just a hybrid car that ran on hydrogen enriched air fuel mixture. But I slowly started gaining more energy in the car then it was consuming from the solar.

So I decided to build a command system that ran the car.


Then built a forward looking lidar system Long before Velodyne became mainstream


It compiled images that looked like this.



The principal was simple. Learn the layout with tons of depth field camera photos and draw a GPS guided map. This system taught my car its bounds of the road. Common stopping points and geographical issues as well as speeds and directions.

I then graduated it to a more streamline 360 Degree system that was a 12 laser diode array against 3 webcams to build a 3d presence along with my Depth camera. I also threw in regulation and monitoring of my car computer. Control of my transmission And then the basics like music.


I then started to expirement with 3d Mapping of realtime pictures.


As well as Image understanding.


I realized that the tall monitor had a high distraction issue with only the corner being touch screen. So i removed the touch screen option and went military selector style for the interface to help minimise distracted driving.


After a few system faults. and fires that created me more worry then ever. I decided to rebuild everything.


Then financial hardship hit me and the project came to an abrupt halt. Over time I found other projects that didnt cost as much. And around that time my sister was in need of a car and we had an extra one. So the project got scrapped out and the car cleaned up



Gave it a rather neat looking paint job and gave it to my sister.

Givin the light of the situation. I've always wanted to get started up again. But never had the funding. Maybe one day I will find it. I always wonder what it could have been if i continued. Especially now seeing how amazing the self driving car movement has become.

Did the ALS Ice Bucket Challenge lead to Tide Pods?

3 weeks ago by engineerisaac 0 commments 55 Views

At first glance you wouldn't think about much correlation between ALS and Tide Pods, that's because there isn't directively but subconsciously there's a connection. The ALS Ice Bucket Challenge moved people to be bold to inspire others and to really create a sheep mentality of hay that person is doing it so I might as well be doing it too. A lot of people decided to pour cold water on themselves completely unaware of the actual initiative.

But then shortly after other types of challenges started to pull up and a lot of them were haphazardly and 1/2 brained ideas. Collectively YouTube can create amazing Trends and get people to do awesome things but it also has the same consequence of getting people to do the dumbest of things just out of the idea of being bold or popular.

I must be honest 90% of YouTube is a damn good title you could have an entirely trash video but as long as you're making some type of challenging request in the title you're going to get gold.

It's an unintended consequence may be something that we didn't really look at and honestly it's one of those things where when people work as I heard they tend to follow the same direction so in reality we can't really say that we must regulate this or we have to find a way to get people to stop, it was just something random that I found to be quite fascinating with its Association.

The cheapest water cooling PC setup.

3 weeks ago by engineerisaac 0 commments 109 Views

If you love water cooled computers as much as I do you will find that the industry tries really hard to make it more complicated than it really should be. Over the years I've learned that the real way to cool isn't the quality of the devices but really the surface area you are presented with.

Now Im sure ill get a lot of flack for this. But This is the CHEAPEST water cooling setup i could find.

Comcast Optics

Comcast has been at it constantly working towards becoming the leader in cable networking. Pushing amazing speeds and tech though that isolated radio line. They are investing heavily in their image. But one has to ask why? Why do you care so much what your public think of you at this point?

This article is a exploratory expansion that will grow as a Drill down more into the report. But here is what we have so far.

Quote:

Fastest speed we offer anywhere is Gigabit Pro plan which is 2Gbps down/up. In areas we offer it, it is available if you don't take a TV plan. We also have a 1Gbps down/35mbps up plan called Gigabit which is more widely available and available whether you have TV or not. -Dan

Easy ways to make more money.

2 months ago by engineerisaac 0 commments 134 Views

Many of you out there would like to be making more money maybe your living paycheck-to-paycheck well I'm here to tell you that you're not alone. Millions of people just like yourself live paycheck to paycheck each and every month.

Most just like you are wanting to get out of this rut and would like to start amassing of wealth or start getting to the point where they start living comfortably.

Well I'm here to tell you it's actually quite easy to get this way and it requires set pads and goals and It ultimately discipline.

The most important thing that you have to realize is that you are actually in control of the amount of money that comes in and goes out of your life.

It starts with attitude it starts with the perception of going to work each and every day in this belief that you are doing a good job you're working your hardest and your best and not just that you believe it that it also means that you have to show physical proof that you're actually doing well. Why do I say it this way it's because others have to believe that you are doing good work they have to see it just as you do.

Sadly us humans are social creatures as much as we talk about equality fairness and bureaucracy it always boils down to emotion at the end of the day how people feel tense to describe and dictate your bottom line.

Which people are negatively pessimistic we also are really easy to fall into a systematic rut. I'm here to tell you otherwise push yourself everyday to get better to do harder to do more to learn something.

Your bottom line is purely described in how well you work and how well you are received by others. Have you noticed this though you'd walk into a performance review and 9 out of 10 times you're talking about social issues rather than productivity?

Usually they glanced over your merits of hard work to talk slowly about what one co-worker said about you?

Don't let this get you down you have to learn how to brush things off move on get past it because it's important to remain optimistic in the world that's filled with pessimism.

Another element that keeps you down is your spending habits the rich are typically Rich because they're extremely good Savers they're very Savvy and let's be honest they don't like spending their money.

They hoard zeros like you hoard things and that's the difference you both tend to hold things and collect things but between the both of you one collects the amount of zeros in their bank account and one collects the amount of toys they have in their garage.

The crazy part is is that those who collect the zeros first tend to be able to get the second part as well those people are quite capable of playing the long game.

Also there's the matter of debt don't get yourself into debt it may be really easy to look at that credit card and say wow that's a lot of extra money that I could just spend right now problem is is that debt is actually modern day slavery

A good Golden Rule to keep his don't spend other people's money spend your money and only your money.

Negotiate bills as much as humanly possible nobody pays attention to the billing process not MediCal not your internet bill nobody. Most times a company's billing process is so convoluted that not one single person knows how it works they just know the section in which they work it so with that being said you can always use that to your advantage.

Why I Love My Little Pony

2 months ago by engineerisaac 0 commments 85 Views

I know what you're thinking this guy is crazy why would he enjoy a show that was fundamentally built for little girls?

Why would this 33 year old dad absolutely love what this show stands for?

Well the answer is actually quite simple and it needs a little bit of a back story.

Back in 2010 I was working for a marketing firm when I started that company I was in a really complicated part in my life where I wasn't exactly sure what I wanted to do or where I wanted to go with my life.

The company that I was working for was starting to do some very shady and corrupt things and I would start to grind everyday morally about what I am doing and why I'm even here I started watching this humble little family base company turn into this industrial complex of extortion asking me to do things like create tools to help them cheat and lie to their customer base

I would watch my ideas become suppressed and shut down only to resurface as a new relabeled idea from yet another person within the same company

about time where I was starting to lose my mind the fandom broke out and me being one of those types of people who look at everything with the Curiosity Mark I to watch the showm

At first I felt extremely strange going well I'm watching the girls show but then I started getting into the season I started to realize a very very basic and under growing message which technically in this world should be a no-brainer however it is something that a lot of the world struggles with

And that is
being kind to each other.

As strange as it sounds and as crazy as it may be this show gave me the capacity to use these little equine as teaching tools to others about principles of moral and sound judgment.

Ultimately this boost in morale Within Myself due to the show help me stand up for what I believed in and helped me regain the confidence that I knew I had to stand up to what I thought was wrong and on top of that never let anybody step on me again.

But that also comes with a caveat...

The show taught me so much about the idea of being friendly to everyone this notion that a drop of honey will attract more than a gallon of vinegar and as the show developed so did the character defining each and every trait of what a good person could be irrelevant if it was directed towards little girls are not the message was pretty clear.

Friendship is Magic is basically their slogan however it breaks down to a very basic principle of being kind.

This logic I've actually applied to the real world and I have found surprisingly that by being kind to as many people as I possibly can I to have grown exponentially in my life doors open opportunities have come forward due to it.

Success has surrounded me with these darn ponies and for that I am grateful and due to that I will gladly stay that I'm a brony

I will openly defend the idea that this show is amazing I will take the blunt of The Crazy Ones within my fandom because there's a lot of them purely because of this underlying message of being kind to as many as you can

Because of the nature of the show and it's architecture it's really hard for the writers to get political or create some kind of underlining tone that has an alternative motive the equestrian world that was created has this unique architecture to guarantee the message and the world stays as pure as possible

Sadly however the fandom tends to take things and strange directions but that also comes with any fandom and its popularity I reject most of the fandoms Fringe art there's a lot of things that create cringe-worthy and of course there are always the fans who draw genitalia on damn near anything they can to make a buck

That is a section that I outright deny and reject for as far as I see these ponies they are cute as hell innocent and it most are
The craziest part about me telling you that this show has a hard time being political is because a lot of the talent behind the voices have a very deep political agenda in their own personal thing but the neat thing about this show is it sticks to the subject matter and it doesn't allow any of the artists who claimed the voice of the character to push their agenda.


So if this was a mission statement it would go as following

I absolutely love the show I love the characters and I love the message it provides I don't always agree with the fandom in fact most of the fandom is full of people who forget the actual message and look too unnatural desires and at times use art to creatively visualize those desires which in my mind is not exactly a sound judgment and completely counteracts the purpose of the show but as they say rule 34 of the internet has no exceptions.

To me these characters are lovable little vectorized cartoons that portray is incredibly fun message that can help anybody in the right circumstance and that is as far as it goes or will ever go.

Being constantly connected might be a bad thing

2 months ago by engineerisaac 0 commments 70 Views

Oh yes writing this article online could be the Paramount of what you get out of this entire article. But hear me out to the very end

We are intelligent creatures by default we know what is right we know what is wrong we can reason we have compassion and we have the capacity to think for ourselves in great depth. But as a culture we weren't always constantly connected cellular technology combined with social media has given us this amazing ability to be connected at all times

But what if it was a bad thing.

What if we The Human Condition required points of isolation in our life to comprehend and think creatively and objectively without outside influence swaying a sheepish and primitive mindframe. What if some of the smartest Minds of our history and our time spend good amount of time isolated

Now by no means do I think myself as a Visionary or a great leader we talked many times I see myself to be the biggest idiot of them all but what I can say is over the past six months I have tried an experiment I have indeed technologically isolated myself to a limited capacity

And you know what it feels wonderful no I'm not saying that you boycott technology or boycott computers I'm saying you boycott the social interactivity between other strangers

Nothing is more productive than researching how to do something or innovating for creating the social Factor can come after those traits are expressed to share or boost your ego is not always a bad thing but to do it without any type of product or effort can install narcissistic mainframes

People enjoy creative people they like listening to the things that they have invented they enjoy it when they don't have to figure out something because somebody else already did problem we're having though is a lot of people are getting wrapped up on the idea that they need to fill the airwaves or in our case the internet with content just for the purpose of viewing

It gets us as a public try and clamour for something good to watch even in the afternoon of just YouTube alone there is a lot of garbage you really have to dig deep to the low viewerships to find truly good content filled with actual learning and innovation because it's typically drowned out by the noise of the next six reasons why your unpopular


So take a moment and think about the idea of disconnecting I understand that this feeling creates endorphins in your brain that are good on the next notification makes you feel wanted however these traits line up with other instances does simulate the same responses that drugs alcohol and sex can create

Treat social media like a drug cuz that's exactly what it has it shares the same traits there's elements of peer pressure there's a diction there's lows and highs and some special circumstances the addiction can create monetary losses no different than gambling

Make it so addicted to our lives that while we're driving we scroll our Facebook wall we swerve in between lanes not really noticing

Sadly there's a lot of bad that can come from constantly being connected


So if you're going to take one thing from this entire article I would suggest you learn to moderate your activity on the internet to one very simple principle the internet is best used to learn things make friends and contribute positively

When it is used to cure boredom it can do no better damage than a home invasion or assault on persons

Well as many of us think that the internet is Anonymous by the fault everything that you say on the internet has the capacity to be interpreted and red but other people it can indeed hurt feelings that can change people's mind frame your bad advice can get someone severely hurt now granted with that being said I'm not here advocating that you have to watch your mouth or you'll be at fault for anything I'm merely stating that it would be wise to put effort contributing positive content to the world

Freedom of speech only becomes the scrutiny of attack when enough negativity steps forward

And I'm not know I have left this article to run way too long for that I apologize so here I leave it here abruptly
