My career choice...

[korbendallas68]

It has been a long time dream of mine to get into the gaming industry, so I have been looking into schools that can get me there. I want to specialize in Game Art & Design / or Production Development. So far I have eyes on The Art Institute of Orange County Cali, or Full Sail Real World Education in Central Florida. Both are very expensive... Which sucks. But I will find a way to reach my dream job... Its like $70,000 for a 4-year program. I will have internships (Like game tester) at major companies (Like Blizzard North, they make the Diablo Series, ect...). After I complete the college course, they have job placement... Very cool. Lots of the instructors there work for places like Blizzard North...
Idk, I just felt like sharing... I'm so excited! Damn! :P

I want to build the systems that run your games

I am going for Electronic Technology Associates Degree. Currently holding a 3.4 GPA. Then mabey a BA in Nano technology or Electronic Engineering.

I had a soldering iron in my hand since I was 8 years old and ever since then I have always been infactuated with electronics complex and simple based, from TV's to alarm clocks and everything in between. I can repair almost anything even surface mount technology. I know all the codes even before going to tech school.

The Mother board in my computer has under went 3 repairs by my hand and it is an introductory Abit NF7 working (hard) version got it free direct from Abit. They told me to run it and repair it and relay results on a end-user basis. I didn't get paid for but also never had to buy it either or the upgrade.

I also upgraded it to the NFS S version 2.0 retail.

Ive got one for you Juglenaut. Can you derive a formula to calculate how much capacitance would you need in Farads to give you (X) amount of current in Ampers for (X) amount of seconds?

Lyle

[Juglenaut]

Depends on the fequency

[Juglenaut]

2 X 3.14 X fequency X capacitance recipocated = reactance (ohms resistance)

[Lyle's GTP]

Well, it's in a DC 14.4 volt negative ground system. So I believe the frequency is not a part of the equation. You tell me.

So if you have say 60Hz and you need the cap to load 2Ma and the supply is 15 volts p-p AC.

What would you need for a cap(s)?? which would be near 1uF for a 2Ma load on a 5.3V rms on AC voltage of 15Vp-p.

Caps are rarely used on DC voltage unless supplied with a switching current (amps, digital circuits, voltage regulators,), usually act as a voltage peak stabilizer on DC current and can never put out more voltage by themselves than the input source. Almost all electronics run on DC yes, but almost all run at a internal fequency based in the equations of the works to be implied therefore caps are in almost every piece of electronic equipment.

[Lyle's GTP]

Yes, caps will not exceed the input voltage in a DC system. In a car audio system with a low voltage (14.4 volts) and high current draw (100+ amps) would you use a cap that size. It's use specifically is to stablize the voltage and filter out inducted "noise" in the charging system.

Well then tell me how much amp load you looking for hehe lol or more or less charge you need.

In fact all caps act like a 10Mohm resistor in direct voltage I don't care how big it is. Caps themselves in DC don't create a load it is the component accepting the charge that induces the load and only at the input of the source.

Basically you are looking for charge time and total farad value as a base to peak charge time also know as instant amperage draw. Even the huges of caps charge in in Ms and the discharge is rated by Farads. Given that a 1 farad will discharge slower than a small valued cap, but it main use is to obtain a stabilize voltage drops over time in DC.

If for say your Peak DC drops 4 volts the cap will react and discharge to maintain 14.4V untill it hit s10.4 volts which will only last for a second or more.

If you compare a 30 farad cap to a battery in a car....Okay well it won't A battery in a car is a ton> trillon more capacity than a cap...So lets say a battery in a car is 30 trillion Farads and compare that to a cap Hmmm the addition of capacity of the 1 Farad cap is very minimal.

I think adding a power cap to a amp is over rated a business ploy to sell caps which are very simple and cheap to build for hundreds of dollars.

[Lyle's GTP]

The battery thing is true, but don't Caps charge and discharge much quicker. The battery in your car will drop voltage very fast as well if the input source is not high enough. The input source (alternator) is the weakest link in the system. So we need some thing that can stabilize voltage for a short time while the rest of the charging system can catch up. Besides don't batteries have a much higher internal resistance than caps do? Also, doesn't that increase the more you charge and discharge the system?

Lyle

[Juglenaut]

Well to stablize 100 amps of draw use at least 4 farad caps or get 3 batteies or one very good drycell deep cycle.

For the noise it depends on the inherent fequency for the charging voltage...If it is household AC to DC then a leakage voltage persists use several 15V+ 1Uf in paralle across the larger caps.

If you are experiencing voltage interferance try a 20V rated Schottky Diode in forward bias in series with the 1uf caps that are filtering the high fequency noise. By this I mean the caps are in paralle but going thru a diode to the negitive side of the source while the while the positive input is just going to the caps. If you put the diode in paralle with the caps the effect will be erased and the diode will not work. Kinda hairy but it will filter high fequency interferance and voltage leak interferance at the same time.

|=-| High feguency simple filter> this is a rough estimate on the sketch first line positive and the caps are wired to it with positive leads, the caps negative leads go into the positive lead on the diode and then the diode is wired into the last power lead negative Ground. In effect the ripple feqency and any other stray voltage should be terminated to ground.

Also a 50V rated 1h inductor mounted in series to the negitive ground lead will terminate rippling and yield no voltage drop or current loss.

Yes a car better changes resistance as it charges an discharges a cap will maintain it resistance throughout it cycle no matter what. The resistance on a car battery is higher at a dead state or water saturated state and lower at acid saturated or charged state. For a cap to maintain a charge of 14.4VDC on a 4 volt drop is almost instant like that of a bass boom but it recharges as soon as the input allows thus lowering the curent drain directly over the battery for an instant amount of time for the next bass boom. Again I iridarate that the cap does no hold a load the load that it supplies depends on the component accepting the charge thus a 14 amp load will pull 14 amps from the charge but the cap will not carry the load the charge does that is stores thus farads.

Kind of related

I design custom maps on internet games, mainly half-life as a side hobby. It is very difficult and I created a basic map, really small but detailed, in about 4 months.

Please have some leeway I am at he moment

lol wish I oculd be. Damned headers, I can't be drunk when making them!
