Toggle between front and rear view cameras on one display in car?

I installed a front and rear view camera in my car, have a display that only accepts 1 RCA input, and want to be able to toggle between the two video feeds.  I've seen pictures of other people that have done this with what appears to be a simple toggle switch but I can't find any wiring diagrams/instructions.  Can anyone shine some light on this for me and explain how to do it?

Automatic Vacuum Toggle Review? Answered

I'm working on building an automatic vacuum toggle to use with power tools. I'm basing the design on what I found here https://www.instructables.com/id/DIY-Shop-Vac-Dust-Collector/ I have modified the base design to allow a little more flexibility and to make the switch box portable: https://wiki.jasig.org/display/~edalquist/Vacuum+Toggle The part I'm most unsure about is the simple RC network that is acting as a time-delay for the big relay. I've done a bunch of reading but it seems like ever RC delay diagram I find is different. I have the big parts on their way and will be stopping by a local place for the small stuff. I'm planning on posting a detailed instructable once I get the thing working.

Help wiring a toggle switch??

Hi there, i need some advice on how to wire a toggle switch between a battery voltage monitor and a battery so that I can switch the monitor on and off as required. My problem is that i need to pass 4 seperate wires through the toggle switch however I do not know enough about how a toggle switch works to achieve this. Here is a video that shows what I am trying to achieve; http://www.youtube.com/watch?v=YPLNywzmnAk&feature;=feedlik This is a voltage monitor for a lithium polymer battery for use on an Airsoft Electric Gun (AEG) the battery is stored inside a plastic box ,which is shown below, and i would like to insert the voltage monitor inside the plastic box with a toggle switch for turining it on and off I have some pictures attached to show what exactly it is I am using and to hopefully explain more clearly. Any advice at all would be greatly appreciated as I am at a loss about how to approach this.

Toggling LCD Backlight with arduino ?

Hey, I'm working on a project where I need my LCD to toggle between On/Off.  By default, the LCD is OFF showing nothing. When button is pressed, LCD should be ON. When the button is pressed again, the LCD will display a “shutdown” warning message at which the user can confirm or cancel. Right now, I just need the ON/OFF function to work (without warning message). This is the code I have been trying, but it doesn't work properly. #include #include const int Temp = 0; const int Press = 1;      const int Noise = 2;          const int Settings = 3; const int ON_OFF = 8; const int LCD_LIGHT = A4; int buttonState0 = 0; int buttonState1 = 0; int buttonState2 = 0; int buttonState3 = 0; int buttonState4 = 0; bool isLcdOn = false; LiquidCrystal lcd(12, 11, 4, 5, 6, 7); void setup() {   Serial.begin(9600);   lcd.begin(16, 2);   lcd.noDisplay();   pinMode(Settings, INPUT);   pinMode(Temp, INPUT);   pinMode(Press, INPUT);   pinMode(Noise, INPUT);   pinMode(ON_OFF, INPUT);   pinMode (LCD_LIGHT, OUTPUT);     } void loop() {   buttonState4 = digitalRead(ON_OFF);   if (buttonState4 == LOW)   {     isLcdOn = !isLcdOn;     if(isLcdOn){       lcd.clear();       lcd.setCursor(4, 0);       lcd.print("WELCOME");       lcd.display();       digitalWrite(LCD_LIGHT, HIGH);           }   }     else{       lcd.noDisplay();       digitalWrite(LCD_LIGHT, LOW);     } delay(2000);   }

Toggles, LEDs, and Ultimate Frisbee

So here is my challenge. I play an ultimate frisbee pickup game every week (Tuesday at the Harvard commons in Cambridge, MA, at 7PM stop by and play!). We have a great LED frisbee that extends the games into the night, but once it gets really dark telling teams apart becomes challenging. I hit upon the idea of making LED 'throwies' for one's body. Take a little 3v watch battery, tape the leads of the LED on with some electrical tape, and then use a safety pin clip it onto to clothing, and blamo!, you have an LED pin that makes playing ultimate frisbee in the dark surprisingly easy, fun, and colorful. There are some problems with this. First, it takes a little time to wire up the LEDs. It is a fun group activity to start with, but this is a pickup game so people wander in all of the time to play, and each time this happens someone has to run off to make some more LED pins. It would be awesome if I just had a bag of them ready to go. Second, I have to pull the pins apart after each game. Third, my red and yellow LEDs (blue and green are fine) really need a resistor as they tend to go dull. Finally, I would really like to make these guys a little more robust by fixing the leads on more solidly. So, with that said, here are some things I could use some ideas on. 1) Cheap toggles. I needs them. I would be willing to toss a few more dollars at these pins if I didn't have to tear them apart each time. Toggle switches would mean I wouldn't have to tear out the battery each time. I am having a really hard time finding cheap small toggles on the inter-tubes. Does anyone know of some good places to look? There is also the added challenge of finding a way to attach the toggle in a mildly robust manner. 2) I am looking to rig these pins up into something a little more sturdy. I was pondering soldering the LEDs to the 3v coin batteries I am using and then super gluing the solder. Is this workable, or should I just break down and buy some battery holders? If battery holders are the answer, again, does anyone know of a cheap place to look? Finally, does anyone have any other interesting suggestions? I am willing to drop a little money into the project, but I really don't want to be spending 5 dollars per pin. In my ideal world my final product would look like an LED, a battery, and switch mounted on a safety pin in such a manner that if someone sticks it to their shirt and rolls into the ground it doesn't break. Getting all of those things to come together in an even vaguely cost effective manner is proving to be a bit of a challenge. Any ideas would be great!

switch help

I'm doing a school contest with a car which requires a toggle switch. I'm gtoing to use a dcd to dc converter to give me an edge. The only problem is that it needs to be a momentary switch. whenever you push the switch down it goes on. Whenever you push it down again it turns off. Any idea for a circuit so that a spdt (3 pins) toggle switch will act like a momentary switch each time it's flicked for a time like a second?

how to toggle two LEDS with transistors? Answered

For my electronics class, we had to program an arduino and build a simple circuit. I opted for a traffic light that switches its lights when a bathroom is being occupied. For the real project I used a bipolar relay switch, which I can toggle with just one output from the arduino. This system is now built in in my local coffeeshop. The thing is, I have to do an assessment about this project, and  it is not possible for me to use the original system, and I don't have a relay laying around. I do however have multiple transistors. Since these are electronic switches, just like relays, it seems possible to me to use these to turn one LED on and the other off and vice versa, with only one signal. I can't come up with the proper schematic for this.. can anybody help me?

router bypass (/w toggle switch)

Hello, it's been a while. This problem requires someone with IT experience, and basic wiring. (the two go hand-in-hand really.) An ethernet cable is made up of 8 color-coded cables. the colors are brown, brown-white, blue, blue-white, orange, orange-white, green, and green-white.(for ease of coloring, I didn't differentiate between the mixed/solid wires) The principle works similar to that of a lag switch. The solid orange cable handles the data flow, and in lag switches it is "cut" by a  simple on/off switch. But here, Instead of the solid orange cable being "cut" by the switch, it simply switches the input. Hence the toggle switch.  **I realise you can do the same thing with port forwarding, but however hard I try, it does not work. Even software made to do it won't let me. Before i go out and by 4 ethernet cables that i don't need, i was wondering if this concept would work. From the modem out, the ethernet cable is spliced into two wires, which had two paths: path 1: directly to the router, out a router port and to the switch (red line picture 2) path 2: directly to the switch. (red line picture 3) from the switch, the cable goes directly into the computer tower. with a simple flick of the switch,  the input to the switch would either go through or bypass the router. although the green and blue current (amps) is split, the amperage is joined again at the switch because of Kirchoff's current (?) law. although the orange is split, it cannot flow through both wires at the same time because one will not have any place to flow. because the internal wires are twisted to reduce interference, I would use the required minimum of 2 feet for any segment. Q1: would this work? Q2: if so, would this effect the router because the power is split.  Q3: if so, would an 8-pole toggle switch be the solution? Q4: would this have any negative effects with the power going moving at different rates (destructive interference) Q5: would an alternate setup be more plausible? (see picture 4) Thanks in advance -Pyro

How to create a simple on/off toggle button for small LED light?

I have these small LED spoke lights for bicycles. It operates by screwing the black plastic piece down to complete a circuit with the battery. Unscrewing breaks the connection.  What I want to do is create a button that will complete/break the circuit turning the light on or off. I don't want the end result to be much larger than it is now if possible. The reason for he size constraint is because the light will go inside a small rubber ball. Squeezing the ball will press the button. This seems like a fairly simple task but my lack of circuit/electronics experience (plus this head-cold) keeps me from thinking of a simple solution. Maybe a toggle button is asking too much (too large, complex?). If so, I'd resort to have the light come on only while pressed down. This seems simple as well (bending a paperclip just right does the trick, but I'd prefer the on/off toggle. I appreciate any tips and suggestions. I can also answer any questions to make things more clear if needed.

The clock i'm using has a push button for the snooze and a 4-way switch for the alarm on/off and settings. I figure it'll be a lot easier if I just tap into the snooze.

Need Help with record player wiring/electrical

Hi this is my first post here I have a self contained record player. Its from the mid 70', in great shape and looks really cool. I want to use it to play records and also to play an ipod. It has a mic jack that I use to hook up the ipod. Everything is great except one detail I overlooked - anytime the the record player is turned on, the turntable i engaged. Picture it as the ipod playing nicely yet the tuntable is spinning the whole time. What I dont like about that scenario is that the turntable will be getting heavy use even when its not technically playing a record. So I am really hoping to come up with a way that to disengage the turntable yet still get power to the unit. I took the thing apart and inspected it last night. There are 2 and only 2 wires running to the turntable portion of the unit. My thought is that if I clip these wires and add a toggle on/off switch that i could power up the unit and then control the turntable separately with this new on/off switch. It seems kind of simple to me BUT I dont want to do anything stupid and ruin the entire thing. Also I have no idea if by adding a on/off toggle if somehow theres an unequal distribution of power that can cause problems...basically I dont know much!! so if anyone has any thoughts Id love to hear them! thanks so much. if anything is unclear I can post pics too if that would help. thanks so much! eric

More UI/website features ideas. Free to use and abuse, feedback welcome.What if Ible's had the ability to tag a user in a comment? For example if I'm looking at a simple robot design made by a user, and some of Randofo's excellent simple bot content is relevant, then I could post a tip/question/comment tagging @randofo to alert him of the content. This could be useful to promote collaboration and increase user interaction on the site. Obviously users should have the option to turn off or modify their taggability, to prevent them from getting spammed.What if there was a switch that allowed a user to turn on a public request for tips on a project? This would just be a little checkbox on the author options sidebar of an Ible that would turn on or off a little icon on the project thumbnail (on the bottom bar where the views and star options are already) preferably it would be orange to be noticed. I think this would be a great way for users to indicate that they actively need some help. Obviously a master woodworker posting a woodworking project would not necessarily need this feature, but a home tinkerer trying to figure out a difficult project would. I think this would really help increase the impact of the new tips feature.

I'm looking to make a device that will play random sayings when toggled. The idea would be it would say one random, pre-recorded saying of a list of...say...20. Once played, it would stop, and not play another saying until toggled again: in other words, if you press and hold the button, it will only play one recording, regardless how long you hold it down.
