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?

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?

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

Multi circuit switch

I'm sure everyone on here has seen a million post on switches but this is a bit different... maybe. I need a switch that has 3 positions on-off-on. I have seen these. The only thing is I need it with multiple circuits. I don't know how to explain it, but I think I need something different. More like 4 pins instead of 3. Im very new to the DIY scene so if this is a absolutely stupid question let me know. I'm sure I'll have more to come! lol

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.

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.

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

Best way to switch multiple circuits?

Hi, all - first time posting. I have limited knowledge with electronics and have come across a scenario where I basically need a kill-switch for a cable with 9 ends. I can't find any sort of toggle switch (SPST, DPDT, etc..) that would accommodate that many wires. I started reading up on digital bus switch IC's. It seems a 10-digit one like this would work, leaving one unused. http://www.digikey.com/product-detail/en/74CBTLV3861PW,118/568-8418-1-ND/2765135 My question: is this the easiest solution? I simply don't know what all options exist, so any advice from someone more experienced would be greatly appreciated. Thank you for your time. -Caleb

Switching voltage inputs with a chip

I have a small project I'm working on that uses rechargeable batteries.  However I want the device to stop drawing from the batteries whenever an external power source is plugged in.  (The external power source would then power the internal battery charger and the main device.)  Is there a chip or circuit that could be used for this?  My only alternative is to modify the power supply port to include a micro spdt that will switch when plugged in.  But I'd rather like to avoid that.

How can I control the up/down movements of an electric hoist?

I have a hoist that is a northerntool.com/shop/tools/product_200660033_200660033. I would like to control the hoist's toggle switch circuit which has a LMG CBB60 capacitor (25uF+ or - 5%, 250V AC C40/70/21 50/60HZ). The hoist is 110V, 125 watt output, 1.5 Amps, 1.7 HP with a lifting speed of 16.4 ft/minute. The duty cycle is 10 minutes at 20%. The weight to be lifted is less than 50 pounds. The hoist also has a limit switch.  I would like to be able to specify 15 up/down movements of the hoist that can be repeated. My question is how can I do this? Any comments are greatly appreciated. Please see the attached images of the limit switch and the toggle switch. The toggle switch includes a large capacitor which is just shown on the right side of the photograph.

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!

Leonardo - Warning System + Voice Recognition

I designed and built a warning system, using 3 sensors, that detect when an object is approaching. The system also has a toggle switch and a buzzer. When the toggle switch is in the OFF position: If there are no objects nearby the LED turns GREEN, if either sensor 1 or 3 detect an object the LED turns YELLOW and finally if the object is between sensors 1 and 2 or 2 and 3 the LED turns RED. When the toggle switch is in the ON position:  Same as OFF position + buzzer  beeping depending on color of LED. Now I would like to add voice recognition to my system. I purchased a JY-MCU Bluetooth Wireless Serial Port Module and was able to test it using a simple program that changed the color of my LED depending on the command I gave it using my phone. My problem now is that whenever I tried to add the voice recognition capability to my warning system its not working. The code I'm using makes sense but I'm new at this so I might be missing something. I'll be posting 3 codes: 1)Warning System 2)Test for Voice Recognition 3) Current non-working code.

Help Replace Discontinued Range Hood Vent Fan Switch

The variable speed fan control on my Thermador HT48HQS hood vent does not work and the replacement switch is no longer available.  I'm looking for some help in making a new switch.  The Thermador VTR1000Q motor is mounted on the roof and controlled at the hood with a variable speed control knob. The motor is rated at 115V 60Mz 7.8 Amps. Photos of the switch assembly are attached. From what I understand, the speed control knob is a potentiometer that regulates the speed by proving a range of amps from 2.5 to 8? If I could make a variable speed control that would be great.  But I'd be more than happy to have create an on/off toggle switch or a toggle for low on/off high.  Can anyone help me?

Electronics Question: Double Switch

I figure that this is a simple question, but I have a pretty limited knowledge of electronics. Would it be possible to hook two switches up (in parallel) to an LED, so that if either switch was toggled, the light would go on? I'm almost definitely sure it would, but just wanted to make sure. Thanks!

LED Help (no0b)

I am just getting into building my own electronics/gadgets. I have decided that my first project is going to be a simple (hopefully) led light that can be toggled on/off via a small push button and most importantly can be toggled on/off when in contact with a metal rod. So, when the led is in contact with the rod, it will turn off, and when not, it will light up. The power source for the led will be a cr2032 (3 volt) battery. For a visual, think of those small led lights that you can add to your key chain. It pretty much the same concept, but if the led was on, and you were to place it on something metal, it would turn off. I think I can bring my project up to the point of a working led with a push button, but have no idea on how to set it up to turn off when in contact with metal. Any help would be greatly appreciated. Thanks Dan

Modifying ATX Power Supply for 12v Power - Easiest Method?

I'm building a small box with toggle switches on it. I want each toggle switches to turn on something simple (mostly just LED lights). I was trying to think of how to power the box, and I thought about using an old atx case power supply since I've got an old computer I could pull it out of. I'm seeking advice because I have no experience with wiring at all.. and I don't want to burn the house down. :) If I jump the green and black wires on the motherboard plug so that I can turn on the supply, couldn't I just buy a simple molex Y-splitter and plug it into an available molex plug, and then cut the yellow and black wires and use those for the power and ground? Here are the Y-splitters I'm referring to: http://www.amazon.com/Computer-Molex-Power-Supply-Splitter/dp/B001PI9AAC Cut off the plugs from the Y, and run the yellow and black wires to my switch and then run a power wire from the switch to the LED light or case fan or whatever I'm powering off of that switch. The switches I'm using are 12v automotive toggle switches. Would this provide the power I need? Would it be too much power? Should I put in an inline fuse or a ohm resistor or something to make it safer? I appreciate any opinions.. I'm curious if anyone has ever used a molex plug in this kind of way and how it worked. :)

Replacing switch and extending them.

I have this extension cord from panther, http://www.panther.ph/wp-content/uploads/2012/05/PSP-0211.jpg. Now, I am planning to replace its rocker switches to toggle switches and extend it because of a wooden table project. This wooden table will have its power control panel mounted on its front and the power outlet will be hidden inside the table. My idea is just to copy its wiring for the new switches once I acquire the materials needed . Here is its inside btw. http://imgur.com/xOHhg5i.  My problems are I don't know if this idea of mine will work or if it will, what kinds or specifications of toggle switches and wires I'm gonna need. Once I thought that I could just make an ordinary multiple outlet/extension cord with individual switches but I need the panther's features. So that I wouldn't have problems in breaking the appliances connected to it due to some electrical problems. I have almost 0 knowledge when it comes to electronics.

Ipod sync and audio cable mod

Hello, I've been thinking about making my own iPod dock build into my desk. One of the features I would like is that I can also listen to music while it's docked without having to put an extra cable in the top.  Now, I know cables exist with both USB and stereo line out connectors. So this should be possible.  However, since I want to work the cables away it is gonna be plugged into the USB port of my computer all the time.  I'm not 100% sure on this, but I'm guessing that the iPod will go to sync mode once I connect it without the ability to play music before ejecting it in iTunes.  What I want to do is make a toggle switch, so I can choose between sync and charge or audio (or better even, audio and charge if this is possible) My guess is that the best way of achieving this is to put a toggle switch on the data+ on the USB line, since the iPod can no longer recognize the computer like that (and therefore will not go to sync mode) Am I correct in this? I am aware that it will not charge this way because of the voltages needed on the data pins for charging.  A better solution would be to switch both data connections from the standard USB connection to the voltages needed for the iPod to charge (causing it to still charge in audio mode). However, I'm not sure how easy this would be to achieve with only 1 toggle switch (since I need to change 2 cables without shorting them out). I know the voltages and resistors needed (they can easily be found here on instructables or other sites through google) but the switch is what is bugging me.  It would be nice if this can be done without microcontrollers (I never used them so yeah...) If I need to build a circuit that is ok (soldering isn't the problem, I just don't feel like learning to program a microcontroller just for this project) Can someone please tell me the best way to achieve my goal, and if it's possible at all.

Project Help

Hey everyone I was hoping someone could help me with a project that I'm working on. I'm relatively inexperienced with electronics so this might just be a simple solution, but here it goes. I have a 4.8V, .9A power source and I would like to connect the power source, a toggle switch, a LED, and a USB port in series. A pretty simple idea. I don't know too much about LEDs, but I do know that you have to use a resistor with it. And I've heard that the LED and resistor have to have a voltage drop equal to the voltage of the power source. My main question is this though: how can I use the LED along with the USB port? Will there be enough voltage left for the USB after the LED is lit? Thanks for any advice!

No, that doesnt look right... Potentiometer Expert Needed!

Hi All! My brother and I are building an e-bike and we THINK we know how to attach a throttle, but it might blow up the battery... if worse comes to worse then we have a toggle button we can install but it's not really ideal. I've attached a circuit diagram below of how everything goes together, but this is my thinking; With nobody touching the throttle, in my circuit, wont i have a current flowing from the battery anode via the potentiometer straight back into the battery cathode? This results in a huge waste of energy doesnt it? And the battery would drain even when the bike is stored in a hallway overnight.  So, does anybody know if this circuit will work? i need it to take energy from the battery ONLY when active.

adding remote button to halloween screamer device

Hello! I am pretty new to all this. In fact, this is my first project. down to the dirty part. I have a battery powered screamer toy. It has a light sensor with a toggle switch and a push button that both activate the speaker.  I want to add an external button in place of the internal one located on the circuit board.  I have added a length of wire to the board already.  One end to the contact push button on the board, and the other to the point that connected to the other end of the contact push button. I scraped the copper off between the point where the second wire connected to the contact push button so now the only way they connect is through the added wire and tactile button.  My problem is this.... none of it works now. Not even the light sensor.  Please help!

There are a lot of nice features, but at least one bug(?) and a couple of things I wish were different...Like the bigger patches :-)Like the icon format for my I'bles, favorites, and groups (on the /member/... version)Like the no-longer-present "(0)" in the INBOX link at the top of my pageDon't like the no-longer-present "(1)" "(2)" etc. in the INBOX link at the top of the pagePossible bug: Why are there "short lines" in the icon layout of my I'bles?Why don't the icons have the "featured" or "winner" banners?Would like the icon format on the /you/ page as wellWould like the "icon vs. long-line" toggle buttons for both viewOverall, the changes are light and subtle, but give things a look more consistent with the rest of the site.

wiring help

Im working on a fireworks show and i just bought 25 toggle switches and led's from a garage sale for 5 bucks.. never opened still in packaging. how would i wire all this up to show when its armed a light would show on each channel.. im using this thing to ignite the bigger fire works (2 per switch)... i got around 360' of extra red insulated wire laying around from the shop i work at in the summer becasue they are throwing/giving away. any advice i also got a few rca and 1/8' male and femail jacks and a few push buttons from salvaged things... could i also use the thingys from cameras that put out 330 volts i have a few of those. you can contact me on meesenger also at:deer_hunt05@hotmail.com

LED cube 3x3x3

I hope this goes to a place w/ someone who can assist me. I built my cube wrote my code.  My C skills are very limited and something like this would strengthen it I imagine.  I would like some help in creating the letters though, kinda like they did in the blue 8x8x8 demo with the INSTRUCTABLE.  So far I cannot make all the LED's light up in a single column, and make another column light up only one or two simultaneously.  I'm lighting the whole thing.  I understand the multiplexing and the lights in each column are toggling faster than I can see, but I still would like an idea.  I'm going to do an 8x8x8 for capstone and would like to get familiar with this one first.  Using the arduino uno and software.  Any tips would be appreciated. Thanks

Combinational Lock using shift registers

Last year, i made the circuit of this already but now my brother is asking for my help and i cannot remember it now. im focusing right now in programming and forgot my logic circuit skills..please help me to remember this... what i remembered is that i have shift registers that memorized the buttons (0-9) i pressed...then i enter again a sequence of numbers and the device will check if it corresponds to the numbers i entered...the led will light if it is correct and will not if the numbers entered did not match the default numbers... i still have the list of some materials, 3 universal shift registers, 1 nand ic, 3 xnor ic, 10 toggle switch and 1 hold switch..  its not a very complex circuit..my only problem is to remember on how will i work with the shift registers... please enlighten me once again

LED relay switch... maybe?

First off thanks for looking and helping if you decide to. I have only been working with computer electronic in a DIY since for about a year. My question is, do I need a relay for what I am trying accomplish and if so what kind? What I am trying to accomplish is: I have two push buttons (momentary contract switches). And I want it so that when I press the first button (orange) the first LED turns on. And when I hit the second button (blue) the first LED turns off and the second one turns on. Kind of like a toggle but only with the LEDs. The buttons are also connected to a board that is connected to my computer via USB. Which is where the power is coming from for the LEDs. I can use another source if necessary. I drew a little picture to help describe what I am trying to describe.

LED Guitar Pickups???

Hey guys,I'm interested in putting LED lights in my guitars pickups. I've seen a few people do this on the net and gives a brilliant effect.I know to put this all together on the guitar, the only problem i have is making a circuit for the LED's. I know there are instructables on how to wire LED's but none show any circuit with a switch.I have all the equipment needed for this, eg. LED's, resisitor, 9V battery, toggle switch, wire etc.So basically i'm asking whether someone would be kind enough to show me how to wire 2 series circuits which both consist of 4 LED's which connect back to a switch and a standard 9V battery connector.And if possible, close up pictures would be very helpful.For an idea of what i am on about here is a video of someone who has already done it, but i didn't find his instructions helpful at all.Any help would be much appreciated.Thanks Dan

Wiring DPDT 20 Amp Switch

I am in the process of building a MAP Sensor for my vechicle using a 20 Amp DPDT switch with an 100k Potentiometer. I want to use one side for going back to the origianl and the other side for the modification. I also want to have a green light showing when it is in the original condition and a re (warning) light for when it is in the modification mode. Can I do this? If so How about showing me how to do so. I have attached a picture of what I am trying to do. The toggle switch has 6 blades and I don't understand the schesmatic in hooking it up. I am attempting to make two into one. the upper switch is to control the Potentiometer on the left with the green and red lights above it. The bottom switch is to control the one on the right. When both switches are in the original circuit, both gree light should light up. When they are in modifying mode both red lights should light up. Hope you understqnd wht I am trying to say here.
