Does any one know how to connect a web cam to a crt monitor without a computer  or a VGA camera to a crt monitor

When I click "connect with Facebook" button here is what happens: it tells me to sign in, then to accept instructables (witch I did) and then the window closes...2 seconds later instead of your Facebook account badge on instructables it just says "connect with Facebook" again! PLEASE FIX THIS

I tried entering some codes to try to connect my samsung t301g to my mac. The phone didn't do much. I wasn't sure if I am supposed to enter the codes in the main menu. The link shows the codes that should work. http://www.metacafe.com/watch/582887/unlocking_hacking_tricks_for_samsung_cells/

How would you connect the wires from a USB (female) with wires that are red, black, green, and white, to a 5V boost regulator that only had three legs - Vin, Ground, Vout?  It's not for a computer so I don't think we need the green and white wires, but I could be wrong.  Which wire goes where?  Thanks!

I have an old iPod touch that I can hook up to my tv I was wondering how can I use that  To connect my new iPod touch to my tv wirelessly  like I want to old iPod to be the receiver  then I would tv out that on to my tv any suggestions thanks in advanced .

Hi guys, I think I might need a little help linking my instructables to my facebook.  I have tried using the button several times, 10 I think, and I have made sure I carefully put in the username and the password correctly, but whenever I click sign in it always gives me a blank screen?  Anyone else having the same problem, and does anyone know of a solution or a different way to connect the instructables and facebook accounts?  Or is my facebook connected and I just cant tell because of the blank screen?  When I log onto facebook seperatly it doesn't show in any way that I am connected to instructables.  All of your answers would be helpful.  Thanks!

Hey Guys.  I have a laser tag project that I am making. Now I want to put high pressure air recoil on it. With the HPA being in the magazine and the recoil being a blow back valve in the gun. The issue I have ATM is the connection between the gun and the magazine. I basically want it like a butane connection. I can't find anywhere that shows designs or standards for this though. Or anyone who sells these parts. Also I don't want to use a gas magazine as I have custom magazines and guns. Cheers. 

I need to know how to connect a gnss receiver to one specific transmitter to pinpoint its exact location.  If the gnss receiver wont pinpoint the transmitter location I am wondering if theirs another chip that a gnss receiver could use to replace the transmitter.  (If you have any chip suggestion please make sure their small).  I prefer you email me @ jrocky38@gmail.com.

i wonder if an institution has a server what does it mean? - They have their own internet connection or who do they pay for at the end of the month? i have a modem that uses sim card let us call the mobile service providers that i use (xy). can anyone explain to me do the data connection i get come directly from (xy) servers or do i get it from somewhere else. and if( no where does it come from)if yes(who are they answerable to at the end of the month.****am a dummy i know so i dont expect am a dummy as an answer. pls anwer in a simple language

This is a People counter, well hope to be if working.ha. Lazer across a doorway hitting a LDR. The 4 digit 7 seg display counting up 1 each time a person breaks the beam.  As of now i  have a counting sketch from the Sparkfun example. It is counting up 0 to 999 and at the same time i have an LDR reading to the serial monitor and blinking the LED on pin 13. But they are not "interacting". I am trying to get the beam breakes from the LDR to advance the count by 1 every time it is broken. In the loop function is the mills that was advancing the counting. I have changed it to   displayNumber(counter).  Among other things.But i haven't been successful in having the LDR advance the count. The sketch is still missing some "stuff". What could i change to have the counter advance by 1 every time the lazer beam is broken?    Thanks W /* 6-13-2011 Spark Fun Electronics 2011 Nathan Seidle This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license). 4 digit 7 segment display: http://www.sparkfun.com/products/9483 Datasheet: http://www.sparkfun.com/datasheets/Components/LED/7-Segment/YSD-439AR6B-35.pdf This is an example of how to drive a 7 segment LED display from an ATmega without the use of current limiting resistors. This technique is very common but requires some knowledge of electronics - you do run the risk of dumping too much current through the segments and burning out parts of the display. If you use the stock code you should be ok, but be careful editing the brightness values. This code should work with all colors (red, blue, yellow, green) but the brightness will vary from one color to the next because the forward voltage drop of each color is different. This code was written and calibrated for the red color. This code will work with most Arduinos but you may want to re-route some of the pins. 7 segments 4 digits 1 colon = 12 pins required for full control */ #define ldrPin A2    // pin used for input (analog)    int digit1 = 11;

First things first notice: Iam in Europe so it's probably a bit different than in USA. I have electric radiator in my room. i bought thermo switch but i don't know how to connect it between the socket and the radiator. I must mention that the radiator had already same thermo switch before but it broke down after 5 years and I didn't write notes how it was connected. I already blown 4 fuses during the attempt. The wire has blue (P?), brown (N?) and yellow/ green (earth) wires. In the switch there's sheme sticker -> www.shrani.si/f/C/Nr/42sKtVVC/thermo.png. notice i have a plug and wire from the radiator both with mentioned wires. I checked blue wire and it's live (P??). Green-yellow wire is earth.. iam sure. so how do i connect the plug and the radiator?? 

Hi. I would like to know, how can I get the information to ARDUINO ... that other item/pcb has turn on a motor ??? The PCB that the cables are coming from to the motor is power by one AAA battery. When you turn on the pcb, it sends short bursts to the motor, so it vibrates every second (for half a second). Now I would like to know, how to connect the arduino to the motor, so that the arduino would know when the motor is on ??? Thanks

I have a project in mind which would utilize a 12VDC 300ma computer fan. I would like to use an old peripheral wall plug style power supply. I have one rated at 12V 500ma which I think would work fine.  Problem: How do I determine +/- if I cut the male plug off of the power supply without shorting out my apartment building or spending the weekend in intensive care? The cord is marked along one lead with a gray "dash".

I have a 5th gen IPOD video and while I was replacing the hard drive some of the prongs on a circuit board connection (the thing the ribbon wire connects to) broke off. Now the ribbon wire will not stay in place, the ribbon wire goes in but is not very secure. I was wondering if there was any quick and easy way to fix it. I may need to replace the part and solder a new one in..I personally do not know how to do that but I know someone who can. I just don't know where I could pick up a new part...any ideas?

I have an HP Windows 7 laptop that always had fast internet up until 4 months ago. Its been having 2-3, or sometimes 1 bar now. Im trying to use my personal hotspot but thats not even working. My sister has a Windows 7 laptop as well, uses the same internet and still has better internet connectivity than I do. FULL BARS! I know my laptop is capable of having fast speed too, I just don't know how. I think there is a setting or program stopping it from having better connects.How do I fix this?

Hi, everyone! I'm Jess.Before joining the team here at Instructables, I was an Elementary STEM and ESE Teacher, and I have loved art and maker/DIY projects pretty much my entire life. Recently, I’ve seen some really awesome and inspiring projects and noticed that the authors were teachers, so I thought it would be cool to connect here and share what we're working on with other teachers who also love to tinker and make. I'm so excited to learn about what you all are up to and celebrate your crafty, techie, maker awesomeness! :DFeel free to say hi and share about the things you love to create or link to your most recent project in the comments below.

Me and my family recently purchased an Auvio soundbar from radioshack. It came with an RCA cable to hook up to our TV. However, my TV uses an "S/PDIF" jack for audio. I don't know where to get one of these, but it's been really inconvenient having to switch the RCAs to whatever component I'm using at the time instead of just hooking it up to the TV. What should I do? 

I want my xbox360 to work on my sony pmf 42x1 monitor using the hdmi cable.  I purchased a adapter (hdmi to DVI) from the shack.  But when i hook it up i get and error from the sony saying  "not in range".   Can i adjust something on the monitor to allow it to receive the xbox signal?  The only video input i recognize is the s-video.  I included a pic from back of sony pmf 42x1 monitor. thx,  d
