quantum

I figured out my radio problem, as I once told you at http://www.aaroncake.net/circuits/fmtrans.htm I built the circuit, and it did not work. My first estimate is that the transistors that I used does no cover the range that I want for. 300 megahertz. By the way, for what reason are the transistor. http://www.cedmagic.com/tech-info/data/nte123a.pdf

Outstanding idea! GEE! Why didn't I think about that before? Maybe because I already dark blinds and dark curtains, HA! street light does a lot of horrible things, not counting shining into my bedroom at night (which I tried to fix with curtains and what not), but also I am a astronomy entusiast. Which you can propably guess, I don't want any light into my telescope!

Excellent point Peter G. I have thought about that. Your right that does sound somewhat foolish, Ha. However, just having the knowledge to shut the street light off would be cool enough. Knowledge is Power. Also, the street light does a lot of horrible things, not counting shining into my bedroom at night (which I tried to fix with curtains and what not), but also I am a astronomy entusiast. Which you can propably guess, I don't want any light into my telescope! If I could shut it off, I would propably use it when I'm scoping the skies. Having it off all night might be suspicious to the neighbors. I accicdently found a frequency chart. I will give you guys a broad description. Infared electromagnetic spectrum (es) is in the Terahertz, wavelenght is 10^-4 meters, and photon energy is 10^-21. Light is 10^15 freq., i micrometer, and a little less than 10^-18 photon energy. Ultraviolet is around 10^16 freq., 10^-7 meters in wave length and consist of 10^-18 photon energy. I just read that the sun emits huge amounts of Ultraviolet rays, which are ozone protects us from a lot of it. Guess what also the sun emits, Infared photons, yeah! What device gives off Infared photons, Iknow that burning coals, and heaters do, but I'm not starting a B.B.Q. under the street lights. Another thing that is on my mind is that why doesn't it shut its own self down since the light is so close to the sensor, which the sensor is on top of the casing (I'll try to get some photos for you guys)? I think the sensor is sensitive to something, which is not its own light! We have stumbled onto a clue. The sensor are pretty strong/sensitive, so why doesn't the other street lights shut it down? Hmmm?!

1. First off audioguru, how do you use the stubborn "quote" icon? 2. How did you come up with 60mA? Where is the resistance? Hmmm. 3. Who sayed that I neened 1/3 Watt of power? 4. I have no intention to build this project (although it would be useful) at this present time. I am just simply theoretically building it.

Audioguru, are you saying that the 9 volt battery will be drained much quickly? How 'bout if you put at least three 9 volt batteries parallel, having thrice as much current. I have a feeling that all this depends on the consumer prefrence. How 'bout switching the 9 volt battery with cigaret lighter in a car. Would that mess the project bases up?

Ha He. Actully, just having my name under the to 15 posters is propably just as neat as a multitester. ;D

Mixos, off subject, but your penguin cloth on your table is awesome, best thing since sliced bread!

Would it be possible to switch a transformer that is made to transform down, and make 120 volts from 9 volts?

MP, I just found a schematic for a ultra simple radio transmitter, that is suppose to range from 88 to 108 megahertz. Awesome. http://www.aaroncake.net/circuits/fmtrans.htm How does the capcitor determine the frequency, I know vaguely of this.

You guys are hilarious. I'm probably exagerating about how loud it is. he he But just the thought of turning devices off through the air sounds quiet intresting. Thanks for your ideas. MP, do you know of any circuit that can tune in to the mega frequencies?

Thankfully yes. :)

Well, curses. Ante, do know of any other sites that envovle High Energy Radio Frequencies devices?

What makes you say 12? :D No, I'm 13. :)

I'll give you guys something to talk about. Who is the youngest person at this website that posts information??? ;D Try and guest my age?! :)

If I would have none better, I would thought that you live right next door. You are creeply right. It's not your normal neighbors, there kids that love to blasts their rap loudly in their backyard. So thought there's gotta be a way, but I quess you can't. :-[

Are there any other websites like this where you can post information and chat and what not?

Ha Ha. Yes I won't to distort the signals of a radio. (Don't Ask) ;D I thoght something could distort the radio signals, because I've read in a book that if your created static by wires attached to the battery terminals and rub them on a metal file, that it would make the radio sound like static.

I just misused the wording of demagnetized. I'll change the subject wording to distort reception of radio. I would want to distort the sounds of a fm radio, if possible.

Is there a device that can shut off devices with semiconductors through the air. I did that once accidently while trying to build a transmitter it shut the computer down, and reset the clocks and what not.

I am trying to make a radio sound bad on purpose indirectly, such as with electromagnetic waves. I just want tot see if I can make a radio sound "fuzzy" and distorted. Not make it sound better.

How does a metal detector work?

Most people want a clear sounding reception on their radio, however I do not for obvious reason. How can I demagnitize the reception of radios. Any comments would certainly be helpful.

I just wanted to know if laser send out ultra violet rays. Double or single hetrojunction, im just seeing if any laser will work. the lights stay off until the very last second the sun sets, which means the angle they notice(sensor) the light is around 90 degrees. The street light isn't to far from my house, I could possibly become eye level with the sensor on the roof.

Nonsense! The sensor is on top of the street light casing. So lasers are not ultra violet, :-\. How 'bout a double hetrojunction laser, will that work?
