Finding Circuit Components? (resistors, capacitors)?

I’m pretty new to this but I’m trying to put together something from a schematic (see URL) . I made a list of the components and took the list to Radio Shack. On items like the resistors, I was able to find resistors with the same wattage but not the same tolerance. My questions are as follows:

1. Are the resistors and capacitors in this schematic unusual so that I’d have trouble finding them?
2. Are the percentages on the schematic actually referring to tolerance or are they just showing overall signal change?
3. If I am correct in thinking I need to trace down a 6.8K Ohm with 1% tolerance, where is the best place to find such hard-to-get parts?

Thanks!

Is it legal for a school in Ga………?

Is it legal for a school in Ga to install a cell phone jammer? My school principal is a douc*e and wants to do so, and i wanna know if it is legal or not.

Also my high school confiscated students phones for 30 day (30 days!!!! they better pay my 0 bill!!! but they dont.. icon sad Is it legal for a school in Ga.........? ) Is it legal for them to do this? 30 days is insanely long!

Oh and dont give me douc*y answers like "u should do ur work instead of txtn" or something similar…..

in the us is it illegal?

is it illegal in the united states in the state of Wisconsin in your own home to operate a cell phone jammer?

RFID technology highly flawed?

Could a cell phone jammer or a cell phone jammer tuned to the RFID frequency jam it from transmitting data?

In your opinion,would the following be a good invention?

A cell phone jammer in any personal vehicle that activated when the vehicle was in motion.It would stop jamming when the vehicle stopped,in case of emergency.A very short range one contained in the steering wheel or nearby,just to block the driver.Whatcha think?

Are teachers allowed to put cameras in classrooms?

I was wondering whether or not teachers are allowed to put cameras in classrooms to spy on students and see if they are texting. Does it violate a student’s rights? And what do you think of having cell phone jammers put in class rooms?

If you don’t know what a cell phone jammer is, it’s basically a device that sends out strong signals to cancel out the signal of cell phones.

How can i legally block cell phone reception??

It’s illegal to use, sell, or buy a cell phone jammer in the U.S.A. But i live in a dorm with other girls in a corner with a window and they like to come and sit outside my door and talk, cry, and yell at whom ever they are talking to on their cell phone at 3a.m. when in fact there are ten other empty lobbies designated for them to do this. If i ask them to leave they get angry and get louder. So, the only way to make them stop is to stop the reception in my area. I don’t mind it being available during the day so i was wondering if there us a machine i could simple turn on or off. Any suggestions?
