Hm thanks. I don't mind the math at all, infact I find it helpful if they show me the math (as long as they explain what's actually going on in the book haha).
hm that just costs as much basically. How much does it cost to make your own? Would you be willing to sell some schematics? =p
Oh by the way know any good books that talk about capacitors, inductors, electromagnetism, etc? Thanks!
Hey i was wondering if anyone here had one? I am thinking about buying it but I am just afraid that it might fry the usb port :eek:. http://www.parallax.com/detail.asp?product_id=28119 i was looking at this one but the sampling rate isn't that high =/. So its either pay 160 for all that or pay...
But do you need an antenna? I mean i read stuff where for transmitters you don't need a antenna because the circuit acts as one..but what about a receiver? Technically you wouldn't need one either right? And also higher frequency means its better to have a smaller antenna?
*edit*
I made a week...
So does the receiving antenna need power? I mean if i had a metal rod is it safe to say its resonating with all electromagnetic waves passing through it?
Hey thanks for the responses. So yeah in a freshman in college and i took some electronic courses in high school but it was really basic. I am taking some physics right now (its not heavy on math which sucks but it covers wider topics). But yeah i have been to A LOT of sites about radios and...
I heard an interesting story from a friend once, he said he brought a fluorescent light near a power line and it actually light up somewhat he said. Stupid move, but still cool =p.
Hey i was wondering if someone can help me out with radios and whatnot...i know making transmitters are illegal but i was just curious as to how they work as well as receivers. The thing that confuses me is how do you get information to and from the signal? I mean if i made a tank circuit that...
Hey i meant to post this the other day, but someone already solved it simply by useing the quadatric formula =p. I am surprised that didn't stick out. Well thanks anyways =D.
Hey, i stumbled across a math problem that's got me stump and I was wondering if anyone can help me out. What we have are there 2 dependent variables and 1 independent variable (X,Y, and Z respectively). It looks something like this
X = Z²*201527
Y = Z*54794
324634960= X + Y
What I am trying to...
