I am currently working on a project that requires energy harvesting ,so i decided to use electromagnetic induction for the purpose. However I can not decided how to design my magnet and coil combination. All i know is i want 2.6-3.3v and 26mA for round about 4 ns. The setup in brief required a movable permanent magnet and a stationary coil. The moment of the permanent magnetic is like a oscillating pendulum just for once but with a sleed of say about 15km per hours. So can you please suggest me how should i start designing. thank you

Now a days after looking at the electronics items in the market, I am very interested in learning the electronics but I am zero in electronics. Since my interest lies in that I am confident that I will learn as soon as possible. Hence suggest me a very good hand book for reading & experimenting.

Being a mechanical engineering student, i have no idea about the electronics. if someone needs to make any RC robot then he should be aware of the electronic circuits(as i feel). so kindly guide me regarding this...

i ask because the import fees on stuff coming from other places nearly doubles the price of my orders.
Can anyone recommend a book/website where I might learn the basics of electronics? As basic as possible would be nice. I'm just tired of seeing wonderful things on this website I can't make because I don't understand the first thing about voltage, etc.

Any suggestions for titles? I'm a beginner myself, but would like simpler material for kids age 8-12 and simply haven't found any really good ones at the local library - but then again, I might not know a good one if I found it :P Thanks to all.
A neighbor of mine is using some sort of electronic device to eavesdrop on me. And, to harrass me to the point of militery style torture. I have been unable to gain law enforcement support.

Tried to repair to electronic chokes of 4' tube light but cdn't succeed. I'll be grateful if any one can provide a step by step guide with test voltages etc. at important points in the ckt. Already done/checked - Physical checking of any damage/burn marks etc., DC voltafe after rectification is OK, Filter capacitor after rectification is chkd OK, other electrolytic capacitors chkd. OK, one of the 13005 transistors was found defective - changed but no result, Voltages at the transistor terminals chkd and seem to be OK. May pls contact email@example.com B.N.Bhattacharya

I am making a project and i want a way to make two devices that one of them has an LED on it and when the other devices goes out of a certain range 30m lets say the LED either comes on or goes of and i dont want them to be connected.It's for a school project and i wanted it to be small so I could attach them on to bicycles let's say and then if my brother goes 50m ahead of me the LED will come on/go off on his device so that he is aware of the distance between us I know nothing about electronics at the moment, this might put you off helping that's okay i hope that makes sense to somebody and that someone has an idea. thanks

I was taking apart this toy car called a formula fueler from hot wheels and found these to parts that look like leds but on a board. They each have a led thing and two wires on has red and black wires while the other has purple and black wires. The red and black one has thes letters on it "LED REV:03 B4048-0030050" and the one with purple and black has "PHO-TR REV:00 C4331-003-5000". What are these and what are they used for? Should i keep them for future projects?

As I stated in the question I am totally new at all this, I am mechanically capable of tons of stuff , for example my mechanic has never seen my car :), I have always been a wonderer what if , I come up with these ideas and nothing Mainly cause I have no idea were to start, so I am seeking Guidance in every aspect of electronics and I am also willing to start from the beginning.
