Hi there. From 3 years old, I always had a thing for building things and technology. I liked computers and building structures or ‘machines’ when playing with my toys. I still have the same passion now I’m 17-18. After some serious thought, my first school of choice in University is Electrical & Computer Engineering, and second Mechanical Engineering. I really love both subjects, I just have a talent in electronics, tech and computers so that’s why I’m going for EE first choice.

Now to the real topic. I really like playing video games, but it’s not constructive, is it? So I decided to occupy myself with making stuff like inventions, or fixing things, I hope you understand what I mean. I was astonished by circuit building so I invested on a mainstream soldering iron and solder wire. In general, part of my money are used on tools like screwdrivers, wire strippers etc. (when I visit a hardware store, I feel like I’m in Paradise!)

I really like doing this because it is my passion to tinker with things mentioned. I like learning from the Internet, watching tutorials on how to create this or fix this or how this works. So what I would like is some feedback. First of all, is it good to do this in my age? Also, I always want to learn stuff, I just don’t know how to organize the succession at which I should learn (for example, in electronics, should I start from core theory of electronic physics, how components work, or what?)
And last but not least: Could you suggest some resources about building simple machines at home?

If in anything you suggest there is math or physics it’s still welcome, so far it’s possible for a high school student to understand.

Thank you!

The electronic circuits/nucleus of the computer which perform the analytical, computational and logical functions occuring durring the work session..?

The flashing underscore on the screen where the next data will be displayed..?

The data entry point on the display screen which indicates to the suer the computer is ready to accept commands..?

A collection of characters of information..?

the short term memory used for storing and retrieving data while working on the computer..?

The process of entering data into the computer from storage or the keyboard..?

The storage area that holds the info for/during processing by the CPU..?

A list of options displayed on the screen. The user causes the computer to perform tasks by keying or selecting specific items..?

Programmable keys that perform different operations as assigned by the software programmer..?

The process of protecting stored data by covering the notch or opening the tab to ensure against the accidental erasure of information on the diskette..?

In the circuit given in the url, can anyone check for me how is C4 connected?I use a 9V battery,should i connect its negative straight to the ground or to the C4 before it goes to ground?This circuit looks simple but i find it confusing
Thank you very much mr mike,Another question i would like to know …are all pin photodiodes the same?can i use a pin photodiode of a different type for this circuit?

I’m looking for an electronic lock w/ keypad. I’m looking for something to open/close and electronic circuit (like to turn on/off a light bulb). I’ve searched all over the internet, only finding electronic DOOR locks (I don’t want to use these). I was hoping to find one that has 12 keys (0-9, #, Ӿ), an LED/LCD display (to show keys hit, open/close, or anything else), and 3 LED’s (they would be to indicate ELECTRICITY FLOWING, CORRECT, INCORRECT). Anyone know where I could find something like this? Thanks!
