Looking for help.

I am currently trying to complete a project but cant seem to find anything that would work for it. I am trying to make a system that connects to a wire and on the end of the wire is a resistor of some size then it comes back to the box im trying to make and displays a light saying 1. for wire 1. Then move to the next wire and check it and it would display a 6 for resistor system 6(different size resistor for each number) . Check picture for better understanding... http://img.skitch.com/20101031-fhnufcw7axk1kesj7g4yq1qfrd.jpg

LED Wiring question

Forgive me for kind of double-posting this, but I didn't get much response before. I put up a question regarding LED wiring here: https://www.instructables.com/answers/New-to-LED-wiring-could-someone-help-me-make-sure/Could I get someone to help me out? Again, if double posting like this is wrong, feel free to remove this thread. I don't want to cause problems, I just want someone who's smarter than me to help out :)Thanks!

common ground to 8 separate led driver (possible?)

Im about to wire my latest growlight , and it consists of 10pcs 10w chips, they will be driven by each of their own 10w  drivers, If i would wire as it normaly should be done , that would result in a lot of cable, and i have a long "stem" between the reflector and the foot where i am hiding the drivers! so then , i came up with the idea to wire all the led chips ground to a common wire , which i then split up in the foot  , to each of their own drivers. would this be possible , or would the drivers go nuts,    their different colors involved so driver will put out different voltages Had hoped to finish the project tomorow , so a yes or no is highly apreciated thanks

Wiring your LED

So I just built a new garage and I want to make my own LED lighting for my work bench. I was looking at 1 watt luxeon leds and I was wondering if I need a resistor with those leds? I was looking on ebay and it said that the driver is already installed? I will run these with a PC power supply rated @ 800 watts will this work? Can anyone guide me thru this? Ive been looking on here and reading as much as I can... Thank you.

LED Wiring Question

Prologue:  Please be gentle...once I get past V=IR and the "right-hand" rule, I'm lost to electronics.  But I can solder and follow a schematic. I have several (7) LED sets (each set = 10 LEDs with power pack containing 2 AA batteries, switch, and resistor).  Each set of LEDs are all the same color (if that makes a difference). Image attached. Question:  Is there a way to connect all LED sets to operate with a single switch and maintain each set with it's own power supply? On a lighter note, I'm building a project for some pre-schoolers and want to hide all wiring and switches from those "inquiring minds" and "wandering" hands. Thx in advance. Paul D

Wiring Xbox 360 Fans, Basic Electrical Help, please.

Ok, So I ripped the cooling fans out of a dead xbox, and I'd like to use them for maybe an airbrush spray booth (depending on how much they suck) and I have some total newbie electrical questions. There are two fans rated at 12 vdc @ 0.4 amps each. I have a ac adapter with the same ratings. If I want these to run at maximum on one adapter, what rating do I need? I'm thinking 12vdc @ 0.8 amps, but I have a very limited understanding of electricity, so I'm most likely wrong. Instruct me, Instructables! Thanks very much!

Question on picoPSU wiring

First time forum poster - Hi everyone. I've just purchased a picoPSU 120 (attached pic) for a custom build and it just arrived today. The DC power arrives through 2 cables (duh :), a black and white one.  For - I'm guessing - extensibility reason, the DC cable is cut in 2 half with a 4 Pin Male/Female connector. On that connector, there's the two cables coming in, and the two cables coming out on the other side - all good. But then (as you can see in the second pic) they also do a weird cable loop of the two cables using the spare input/outputs on the connector. Why is that? I don't quite get what it is meant to do.. ?

help wiring aquarium lights

Hi, i'm building a steampunk style ornamental hood for my 20 gallon aquarium, i will be using the florescent lights from two old store bought aquarium hoods and two cpu fans; all to be installed in this new hood. i don't have much experience wiring, i can splice wires with caps and electrical tape. it would be really convientent if i could wire the two lights and two cpu fans to the same power cord and on/off switch. i know there will have to be some kind of converter between the cpu fans and the lights because of the voltage, but what kind and how exactly i dont know. also each the the florescent lights have there own powercords and on/off switches. it would be easy enough splice both light to one power cord but how do i wire them to a single on/off switch? i'd greatly appreciate any comments or suggestions. thankyou.

Help with wiring several LEDs and power needed

So I am trying to set up a table with several LEDs (upwards of 50-75) that will almost all be wired with a switch individually, so that patterns can be created by switching on and off each of the LEDs. I know enough as to set up the switches and LEDs, but I am not sure the best way to go about powering it. I want to be able to plug it in to a wall and not use batteries. but what kind of converter/board would I need to power everthing? Thanks

Questions about Electronics and such I'm a complete noob (mostly LEDs)

So I bought some LEDs off ebay to try out wiring after I read this instructable https://www.instructables.com/id/E9NFEFO2ZGEV2Z9QKZ/. So far I have been able to wire 4 LEDs in a series and connect them in my car . Thats were I am knowledge wise , I soldered for the first time. I have a bunch of LEDs left over and I wanted to make a small sign. I have a few questions.Is there any device (besides AC power adaptor) that can limit that amount of voltage I use? Say like a 110v to like 40v?Is it possible to hook up 25 LEDs in a series with the required resistor and plug it into a home outlet?Is there any type of material that I can use to scatter the beam of an LED?I had a few more questions but I can't recall them right now.

Help with T5 Fluorescent Light

I'm adding a 9" T5 UV light to a small project I'm making. I found a cheap G6T5 Bulb and a Ballast but when I went to purchase the Sockets for it, I ran into a problem. The Bi-pin T5 sockets come in Shunted & Non Shunted and I have no idea which one I need. What is the difference and how would I tell which one to buy to finish my light? Once I have all this I'll have to figure out how to wire the thing. But first I need to know which sockets I need to buy. THANKS!!

Use batteries instead of 12v AC Adapter

I recently bought a couple LED strips from a website, the technical info stated that the strips are ready to go on a 12v AC adapter. I found out I need 160mA to power the small strips I bought; (90 mA for one, 70mA for the other). I'd rather use batteries though, is this possible? I figure since I don't need hardly any amperage then it shouldn't be an issue but I haven't been able to find the right information to prove my thought correct. Thanks in advance.

Wiring 10w leds to 12 volts

OK, I have some 10 watt - appr. 900 lumen leds that I want to use for a video room.  I have low voltage wiring in the walls and have a 12 volt 96 watt dimmer that I plan to power with a deep cycle 12 volt battery.  The leds are 3.4 - 3.6 forward voltage and 350ma.  I want to use 3 of these on each side of the room and was just hoping to get away with wiring each side in series and then connecting both sides to the dimmer. Am I looking for trouble wiring them directly without any resistors?  I really don't want to get into resistors, etc. if possible. Thanks in advance for any thoughts and suggestions.

how to wire a light socket?

Hello,  Me and my girlfriend live in this old apartament building build around 1910.  one of the rooms in our apartament is lacking lighting. and id have a light socket that id like to install. below im attaching images of the place in the ceiling where the light should be.  the wires of the light socket i have got does not have any coloring.  there are 2 silver wires wrapped in transparent plastic sleeves. one of the sleeves has a small bump on it. there is no writing.  i tried to follow some instruction materials but cant reason much through it.  in that room there is a box to turn the light on, and a plug socket. the wire from it goes to middle of the room with this space for light which is on the picture. then from there another second wire to plug socket at the end of the room.  i already know that i need to turn off electricity in the house and about safety. i tried to wire the socket based on instructions found elsewhere first but there was still no light in the room. the plug sockets in the room work without any problems.   i appreciate all the help.  thanks a lot.

Dollhouse wiring

Hi All. I'm a believer in the idea that anyone can do anything with a little info. But I'm in need of a little help.  I'm building a dollhouse for my niece and would like to add a little higher-tech slant (she won't be playing with this for a few years yet...)  I would like to add LED lights (which I will make but just have to wire for at the moment), a flicker fireplace and a door bell all on wall mounted pushbutton switches.  Feel free to suggest anything else that might be cool for a kid... The whole system will run on a 12V adapter but since I need to wire this NOW so I can continue to build, I need a drawing or schematic of how to do it. I've attached a pic of the house and have been pulling apart some of the small flicker Tealights to kitbash into the fireplace.  I have a number of white LEDs with which to make the lights but they don't have to go in right now.  I know I'll need some resistors - where do I place them?  Hide them in the walls?  On each switch? Anyways - any help is so appreciated.  She'd never get anything like this unless I made it for her - I just want it to be so cool that her brothers are impressed! Tbird

Need help with wiring a KJD17 switch for homemade stick welder!

Hello everybody! So, I finally got around and made a stick welder, and it wa surprisingly easy! Now it's just up to make the box it will live in, cooling and on-off-switches and the like. I have a KJD17-switch which I'd really would like to use, it has automatic safety protection against power outages and restarts, which sounds nice enough, considering that this again is an electric appliane that I made myself, meaning more protection is always good! Now the problem is the safety protection, as I do not know how to wire it! Where am I supposed to connect the A1-pin? To pin 14, maybe? I'm afraid I'll destroy this nice switch by connecting it wrong, so if anyone has a clue, please let me know. The datasheet for the switch can be found here. On the datasheet there is the same shematics as on my switch. Best regards Elmo

I DO NOT WANT TO ELECTRICUTE MYSELF OR ANYONE ELSE. I WANT THESE LIGHTS TO BE BRIGHT AND EFFECTIVE. CONVENIENT WIRING/CORDS WOULD BE IDEAL. - What wire to be used to connect couple labeled sockets? (two momentary, two on/off in each side box. both sides triggered at same time) - How do I wire the labeled sockets? Are they connected just like how it’s drawn? - Can those footswitches be used with this set up/light sockets?Or do I need a different type/rated footswitch to do this? - How can I connect and disconnect (for transport) RIGHT BOX to LEFT BOX and power both sides to one footswitch?

Bathroom Occupied Transmitter

Newbie here... greetings! I work in office building with about 20 guys, most heavy coffee drinkers... we have one-holer restroom which is located about 100 feet and around a corner from the area where the majority of the guys work. Needless to say 8 out of 10 times you make the journey to go to use the restroom, someone is in there with the door locked... leaving you constantly defeated and having to go badly.. I want to create a light or a signal viewable in our common room that would indicate when that bathroom is in use. There is one light switch in the bathroom which operates the overhead light and the fan... and the fan is extremely loud so we always turn the light off when exiting the bathroom.  So my thought is to add some sort of transmitter to the switch that when turned on would send a signal to a receiver down the hall in the common room and that receiver would turn on a small light somewhere in the room. The guy next to me has a nice lava lamp and has volunteered it's services as the bathroom indicator. I'm hoping to find a transmitter or replacement switch/transmitter combo that can be wired into the existing single switch box (no batteries to change). This is what I need help locating.  It would need to perform it's current duties.. turning on the light and fan, as well as send the "on" signal and "off" signal to the receiver 100 feet away.  I think the other solution would be to run a wire thru the ceiling from the switch, but was hoping to avoid that. Thanks in advance for your help!

Help wiring an LED array

I'd like to buy some LEDs off ebay and build some LED arrays but I'm confused as to how to wire it. For example, lets say I have 100 watts of LEDs (aka 1 watt x 100 LEDs or 10 watts x 10 LEDs) as an extreme example and each LED has a max voltage of 12 volts. Then lets say I have a power supply that provides 100 watts at 12 volts. How would I wire it? I'm worried that if I hook it up, lots of LEDs will just burn out. Just help me understand what I need to watch out for here. I'm obviously a super novice. Have pity.

Dryer motor

Alright folks, after my last posting of the washing machine motor failed to prove helpful, ( because of my lack of understanding, not the help offered, that was excellent ) I decided to scrap that idea and start anew, this time with a dryer motor. I have a motor here now that like before I simply want to be able to start and stop at will. This time around I have the original wiring diagram too! So, my question is how do I wire the thing, simply with an on/off switch? No variable speeds, no reverse directions, just on/off. Oh, and Id like it run on 110v as well.

LED strip light wire issue

Hello everyone. Sorry for no diagram, but all multi color led strips are all pretty similar, 4 contact points at each cut point. A year ago I bought a 5 meter roll of LED lights. The RGB ones with a 14 button remote, 3m backing, and covered by a jell. Yesterday I bought another 5 meter roll to wire up with my old roll, as the controller (little white box that the 12V plugs into and has the IR reciever) came with leads to connect 2 strips. I plugged them in and they didn't work. So i got out my multi meter and tested my old controller and the new one. and the results came back opposite. One controller, I needed the red pin from the multi meter on the +12V line and the black to go on each color to show 12V. The second, I needed the black pin on the +12V line and the red on the colors to show 12V. So to me it looks like one sends the 12V up the +12V rail and back down the the RGB. While the other is sending 12V up each of the RGB and back down the +12V rail. The led strips that belong to each controller are wired the same. so they don't plug and play. So my question is, Is there a way to get these LED strips to work with one another or will they have to be run on 2 separate systems. Thanks in advance Ross

However, I have no studies or text-book knowledge of resistors, etc.  So I am beckoning the help of you experts out there.      So I have this tiny laptop that is 12v 3amp, 36w.  Okay, so I know this may be a super stupid question, but I've got to ask it anyway.  If my lighter plug in my car is 12v 10amp, can i plug my little laptop into it safely?  I am actually using it with a webcam to make a backup camera.      Second question.  How could I make an adapter that would plug into the lighter receptacle and connect to my laptop.  I have a lighter usb adapter, that is 2.0amps.  So is there a way that i could safely modify it and my current laptop plug so i can plug in my laptop to the lighter receptacle.      Oh, i must add that I know i could go out and purchase some sort of inverter or what-have-you, but I won't learn anything and the whole point of this is to be able to make it myself  (with some help of course) and learn something along the way. Many thanks in advance for anyone who can help me out. Ambles I hope someone can really help me with this.
