    Terms for Datasheet

    THanks again for well explainded answers. About that quote, I don't understand why in the world why and how you would put C- B in reverse bias, however, isn't C to B work like a diode and if you had that "diode" in reverse bias it would leak unwanted current, possibly ;D. Now for the last...

    FM Bug?!

    Thanks! It was bugging me not knowing what it is. ;D

    Terms for Datasheet

    Thanks for the answers. I really understand the Vcbo and other similiar stuff. 2nd page... 1. What is cut-off current? 2. How about current gain? 3. What's Hfe, I know that it's current gain smybol of course, but what about the individual letters. 4. What is saturation voltage? 5. I...

    http://www.datasheetcatalog.com/datasheet/BC/BC548.shtml ( the datasheet for General Purpose Transistor) This site is cram pack with stuff I don't know. I am going through them and asking anything I don't know. All of these questions are on the same page. 1. Under "Features" there is "High...

    Fire Truck Horn

    I figured out that the fire engine horn uses compressed air to make that sound.

    Deep Sounding Chip

    Do any of you guys no how to create a normal sounding sound into a much deeper sound through chips and what not? Thanks in advance, I have a "friend" whose voice is too high, and not deep. ;D

    Vertical line test questin

    Thanks! I just had a question on the test about a true real life happening consisting of two variables that isn't a function. I was baffled when my teacher said that question would be on the test. It sounded like, what is a function that isn't a function. I got exactly what your saying, meaning...

    6V to 12V question

    That makes sense. I beginnning to become really familiar about ground and how all neg. terminals are just somewhat nuetral in some way. What about being able to identify transistor only by looking what is printed on it. I made the flashing LED circuit work with your guyes help about the...

    Identify Custon Chips

    How do you know if a chip/semiconducter is a Ula or custom chip? Would it sometimes be a blob of the material with no written information about?

    Fire Truck Horn

    I want to make a honk but not a beep, a really loud one like fire engine does. Schematics, information, etc. Would for fill my project needs.

    HELP ME - I KNOW NOTHING!!

    Since you say it can only be electronic, its wise you came to this website. What needs to happen is for you to create a small spark, eletrically. This small spark will propably ignite the gases that thingy you sayed was dipped in. And you got yourself a fire. Now into detail on how you should...
