what is this slot in my computer? Answered

I am using a toshiba laptop. Sorry, I dont have the model type. There is this weird slot on the left side of it. First off, there are three USB ports. 2 on the left side, and one on the right side. behinnd the 2 USB ports on the left side is the trapezoidal plug with all the metal prongs on it (name of this please)? but my real question is what is the slot in front of the 2 USB ports? the slot is  about a centimeter tall, and 2" wide. on the side of the slot there is a button. if you push the button it pops out about a centimeter and a half. what is this slot for? sorry no pictures.

RC Noob

I've never done much work with RC control, and i want to build a little rc car with tank steering (2 motors, one on a wheel on each side so steering can be accomplished by which motor is on).  I know I need a transmitter and a reciever (I dont know specifics of each :P).  All I know is that i want to PWM the motors and control with 2 home made H-bridges (motors require max current of 30 amps, so commercially made ESR's are too expensive) and control it via rc. I just really dont know what im looking for in the rc world.

Using a USB port as a power supply to mess with electronics

Hi everyone. Over the past few years Ive been wanting to get around to messing with electronics. Ive learned basic things like ohms law and super basic circuits...(led,resistor,power supply) however i dont learn well with TEXT TEXT TEXT, but rather doing it and finding out what happens. So I have a ton of electroncs laying around which I rip apart and pull components out of.  Today I stuck a tiny 5v, 0.5w fan into my USB on the + and - and had it turn on... Anyone know what else I can screw around with? I would rather do this than use batteries and such. I need a funner way to learn electronics :S Any help please? Fun projects? Thanks

Help with a school project on solar power

Hi. I have a science fair coming up in May and I want to do my project on solar power but I really don't know too much about electricity. This is my plan, please correct me where I'm wrong and tell me if there's a better way to do certain things: I am going to buy a 10w 12v solar panel (I might be able to get a 40w for a bargain) which will charge a battery. Would it be better to get a 12v lead acid battery or a 12v lithium battery? Lithium batteries have DC jacks instead of normal terminals on lead acid batteries so how would I connect the battery in parallel to the 2 devices I want to power? A splitter like this would work but it connects it in series? Although I suppose it doesn't matter because I just need to show that it works at the expo but I'd like to use it now and then. The battery will connect to a 12v LED light and a 12v to 5v USB charger. What about diodes? Do I need them? How will I make sure that the device charging doesn't get fried? Thanks a lot, I appreciate it. EDIT: A charge controller isn't necessary, is it? I'd also like to add in a switch to cut off power to the USB ports, power to the light and power to the battery from the solar panel. This would cause a problem if everything was connected in series.

( I know that the VOLTAGE must be less then 5 v ) but i don't know about the maximum current that i can supply to the pins.. 2) What are the voltage and current for the pins to register a HIGH or LOW?i know that if LOW HIGH .. (correct me if im wrong again) but what about the current? i've posted this in the arduino forum.. i would like to ask it here as there are lots of pros here too.. hehe..this is the link: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1289980113/0?

The fields he wants to learn are computers, general electronics, and robotics. Though he is open minded, and would be willing to stray from those three things. Also, the maximum price per project would have to be AT or BELOW fifty (50) US dollars. Thank you for your time fellow makers. :)?

I've been trying to learn electronics and arduino. The one thing I don't get is when do you need a transistor or resistor or capacitor. I know that Resistors add resistance and what not but when do you decide to add things to the circuit? Like why do I need a resistor on LED's and so on. why can't I just connect it. I feel like I might understand but I need someone to really make the connection for me. I know its a pretty stupid and noobish question.

How NOT to be a NOOB!

After looking around, I have decided to make a Mini-Instructable (Therefore Forum Topic) about how to not be a noob. This will be targeted for Instructables, but most goes on any site. It is also partly targeted on knexers. Step one, The name.Well, a lot goes by what your name is, don't say something like I_Love_Knex_Guns, choose something like Dsman, TheDunkis, Kiteman,Adrian Monk, Goodhart, Dj Radio, Jollex or The Jamalam. Also, try to use one that you use on other Websites, like Mepain, Kiteman or DutchJStep Two, the profile pic, Well, most people hate people who don't even change their display pic, so try to AT LEAST change it a bit. Some people actually use photoshop, like Dsman, or go even further and get one specially crafted by a true master ( IE Oblivitus) Try to get something that reflects either your name, or your interests.Step Three, ActivityWell, posting some Comments is Vital, and the whole point of Intructables is Instructables is just that, Post some Ibles! Don't be all nutty saying "This is my first Instructable, So be nice!'Forum topics are also quite important.Step four, Grammar Grammar is not a NOOB issue, but a lot more people will like you, and try to help improve it that way. Also, there is a Spell check button RIGHT beside the buttons near the Post sign, so USE IT!Step five, Activity Part two ( Bonus Points)Some things that are help you get more popular is greeting new people with nice warm welcomes. Jollex has done this quite often, with a personally Knex-related greeting, as have many other people. Another thing people do is search "knex" and the go to recent, and post something nice on all the new ibles (Block triggers and Et Cetrea Exempt)Example of a great welcome.Welcome!I noticed you'd joined the site, and also that you seem to be a K'NEX fan.That's brilliant!We have a lot of keen K'NEXers here, and we're quite a busy community on the site. Can I ask you to remember a few things, though? We are keen to show off K'NEX in its best light here, so please read these points carefully:(if you don't you run the risk of being labeled as a "noob")Pictures.One of the keys to a good Instructable is good photography. Please, don't use photos where the important bits are too small to see, or out of focus. Use good lighting and the macro mode of your camera. If you do not have macro, make sure things are in focus, then use an image editor to crop off the bits you don't need. Even Paint will do this.Text.This site is used by people all over the world. Lots of them don't speak English as their first language, and use translation websites to read your work. Please, do your best to use proper spelling and grammar, and avoid things like "u", and "r".GunsNow, as K'NEX gunners, we are dedicated to innovation. Innovative guns are what the K'NEXers what to see. But don't limit your self to guns, as some K'NEXers are annoyed by all the guns. And, please, no more little 12 piece guns.More!You know K'NEX is about more than guns, and so do I, so let's see your other projects - have you designed a clever robot arm? A new vehicle? A ball-sorter? Show us!Again, welcome to the site, and to the K'NEX community, and thank you for taking the time to read these hints. For more info click here.>Your name hereWell thanks, and I don't really think this needs a Whole ible, but If anyone wants to collaborate one, PM Me.
