The laser works fine, it's just that I did not shut off the street light off. I keep trying. ;)
-
I have outstanding news. I shown the laser in a light-sensitive night light and it went off, the light bulb went out when it was on in the dark. Awesome. I bet the street light works like that also. Maybe the laser isn't strong enough too shut it off.
-
I understand Mhz, and possibly it may work. What do you by a narrow beam yard lamp?
-
Mhz, to reply to your poundering, we haven't talked about that. My thought to that is I would attach it to a stand, and change the laser so it is always at a costant output (duck-tape).
For all whom are intresting in my idea, I finally got my laser pointer from Ebay. And yes, I tried it, but it did not work. I think my studying and tinkering of the street light helped. As so, whenever the light turns on, it is overwhelming compared to the laser pointer. So, I wait when the light is barely just turning on and point (click) the laser.
The laser specification says the wavelength is 630 to 680, so it could be too much wavelength output.
I haven't given up hope, something has to turn it on. -
So what are you saying, there is a reason they specify 110 volts, and none other?
-
The output AC voltage of my wall outlet is 120 volts. If I were to plug in a charger that specifies for 110 volts, will that effect the charging process (or anything for this matter)?

I want to build a circuit so that with a push of a button, the reciever gets the signal from the transmitter, that transfers to a transducer. Just like a TV remote except I only want one button, and have it be radio frequency transport.
Example: I have my transimitter with the one button triggering, and the reciever which triggers a light bulb to go on. With a push of a button, the light turns on. Just something similiar to that.
If there is a circuit that has multiple triggering/channels, I wouldn't mind, I could modify it.j The range can be at least 20-30 feet min.
It can work in any frequency.
Please ask me for more information.
Just a simple circuit remember. ;D :D -
Do you know what microprocessor I should use? And also, could you give me an example of what connects to pins 3 and 5?
-
Thanks hotwaterwizard! ;D

Would any have a schematic to build a TV remote jammer?
Thanks
Like overwhelming IR diodes. I have seen a shcematic of this TV remote jammer, but I have a feeling I want see it ever again. That's why I'm asking for your help. -
I have a TMP 100 temp. sensor, http://www.datasheetcatalog.com/datasheet/TM/TMP100.shtml
and I have question relating to the applications the datasheet provides.
1. If you scroll down to page 5, it shows the application for the chip. I know what pins 4 and 2 are, but what are the other pins?
2. What chip are you supposed to use for the I2C controller? So would pins 1 and 6 be somewhat input pins? What does SCL and SDA stand for?
3. Why is there a capacitor in the schematic? Would it be so that is doesn't allow low frequencies to pass?
4. What are the purpose of pins 3 and 5 for? Examples? -
Would any know of any schematic for this IC? And is this IC's purpose to block/except frequencies? Then what is bandpass?

Thanks Audioguru, the term of the "ring" made it seem that you were talking about the insulating ring that seperates the channel terminals, instead of the metal ring. Thanks for the picture!
-
I don't understand if the third channel is consisting of the right and left channel, wouldn't that short them. A picture would better explain this. ;D
-
Would any know of a free Basic Stamp-2 microcontroller? Or any microcontroller for a robot.
-
What is a buffer, and how does it work and what not?
-
As much as I know, headphone plugs have three output terminals. The out most terminal is the neagitive, and the inner most is the positive, I believe. What is the middle terminal?
-
Gpg, had do you make that symbol, micro?
-
It is not always to avoid multi-layer boards.
What are multi-layering boards? How would you draw a schematic for a multilayer board, possibly ones with SMD's. Websites containg pictures are always helpful.
Inquiring mind needs input. -
Kain, you say that you have seen leds with 20000mCD. For what unit is that?
I am already ahead of you. I am to recieve a laser pointer that gives off 650nm wavelenghts. I "won" it on 10/06, and is being shipped from Hong Kong. It should arrive within 10 days, which I will tell you of my result. -
A strand of metal wire populates some of the area on the pcb I have, and many others. It is plainly labeled "J" on the pcb. It has zero resistance, and I wonder if it just to carry current that can't get through the without short/parallel the circuit, just like a zero ohm resistor. Why is it labeled "J"?
-
If I am not mistakened, just put the first three bands together, multiply/ divide the number by the fourth band.
-
Excellent research! No I don't have a laser pointer. Would there be any other device that gives wavelengths in that freq.?
Is the wavelength poportional to the power outage? If so, i could reduce the the wavelength by reducing the voltage supply, maybe. -
A tv remote control gives off infared
[glow=red,2,300]photons[/glow]
Is there such a thing that can magnify the infared photons? It is worth a try.

I tried to intensify the laser by putting the laser in front of binoculars, but it still doesn't work. Maybe I should put through my telescope.
