Hi
I need to connect x10 inside a car
I bought a inverter 12v to 110v
I called a stabilizer in some modules x10 but it did not work
Does anyone know tell me why not work?
Does anyone have any suggestions?
-
Myself and I am sure others are probably wondering what you would do with X10 in a car.
-
A) with PLC, without the two systems being connected (house and car) transmissions have no way to get through.
B) It takes a really good (read that as expensive) inverter to produce a clean sine wave output. The square wave tends to let the magic smoke out of the modules.
C) If it's a single cam you want, the inverter can be taken out of the mix as the cams themselves run on DC voltage (some at even 12v).
An advanced search will turn this topic up from the past.

I will second what Knightrider said.
An almost all inverters have a terrible AC outout and I have personally burned a module on a non sine wave AC power source. Noise would also be a factor.
What are you trying to do with X10 in a automobile?
Somethings like wireless cameras can be run on +12 Volts DC if done correctly.

Hi
I'm riding a showrrom inside a mobile van. I'm here in Brazil and the X10 is not used
To provide the customer first show modules lighting lamps, linking TV and feeding animals (http://www.youtube.com/watch?v=bT-DJJMeQ-M&feature=related) in my van
So I need to build a power grid 110 in my car
If anyone has any idea please send me
thanks

Generator?
I know that Honda makes some super quiet models these days that are extremely compact and light weight (and burn very little gas).
The problem again is the sine wave output. The model that I looked at last had a very clean output, was about 4500 watts, was about the size of a PC tower and cost around $3000 USD.

Set-up a small electric circuit in the van without electricity.
Run an extension cord from a reliable household source to power your circuit.
Insert filter(s) to remove any line noise.
Demonstrate to customer.

Ah finally! I can feed the dog from my recliner. >!
My hopes of loosing some weight just keep getting dimmer and dimmer.
-
In addition to dog food I'm feeding chickens (http://www.youtube.com/watch?v=yK4FXo9DFZo&feature=related) and fish through the internet with x10.
With my system I can also turn off my car using a remote control x10. -:)
About the car is off the pc the X10 only helps me ;D
-
I love it when someone finds a new way to turn an old technology!
-
Actually here in Brazil, home automation is a novelty. So here the X10 is a new technology. I chose the x10 for its cost compared to other technologies.
-
alegon,
In Brazil, it may all be new, but I don't know of anybody in the entire world using it to feed fish (or chickens) through the internet.

I don't know if you solve your problem yet but if not you can try this.
1) Get an autotransformer that match yours amperage car output (with I will gess is between 5 to 10 amps). You Isolate any possible van noise to the van it self and get a fresh circuit.
2) Build your circuitry and junp the neutral leg to the casing of the transformer and try to get the casing to earth. Maybe a copper water pipping or drive a rod to the ground (which maybe will be to tedious, hammering in and pulling out an "8 foots" rod)
I can't warranty the results but in your case maybe a good try (never think on this and I'm new to the x10 too), if you try it and works please let me know.

How does a Autoformer that uses AC line voltage work on a 12 volt DC car battery?
Or are you thinking of using the inverters output with an Autoformer?
As pointed out. Most inverters do not have pure sine wave outputs and will at least make so much noise X10 will be useless. Most would be the square wave or stepped sine wave AC will fry the modules. Don't ask how I know this. :'
-
You use a converter
-
Plug it in your lighter outlet plug and use the 120v outlet
-
Most likely the inverters output will be so dirty. X10 will fail or fry the modules.
Though using X10 in ways normally not thought of. Is a real adventure in creativity.
-
I"m an industrial electrician and what we use when we have a circuit with several noise to can control a PLC; We Isolate the noise to the circuit (using a isolated transformer or autotransformer) and start from fresh. Againt I say I'm new with x10 but if the rules apply the same it can be possible. This is just a thinking if I have a problem I will try everithing to solve it even what it maybe don't make sence like fussy logic.
-
But like you said Brian maybe is just a crazy adventure.

Alex,
Is your power 120VAC @ 60Hz? If so, this should do it.

Why Dave is just an Idea, like any other ideas that sometime is was just crazy for everyone else till become a fact. By now if I can ($ wise) I whant to try this my self.
-
I will say that is the way. Sorry I just deal with industrial equipment and I try to solve any electrical problem with the same equipment.

Your first post was pretty disjointed. You basically said hook an autotransformer up to the car. So the question came back, what is a autoformer going to do with 12V DC?
I now understand (I think) what you are saying. Use an inverter but clean up the output. Since an autoformer only has one winding across the line, I don't think it will clean up as well as your other suggestion of an isolation transformer. That might do it, but X10 is very critical of noise on the half cycle and any distortion.
I did find a pure sine wave inverter on eBay where they stressed the output is a clean, undistorted output.

Here are a few web page links that can explain how X10 signals are sent on the power lines and how many things can effect them.

Many manufacturers try to lower their equipments noise on the power lines. By using a AC rated cap across the line to neutral. That cap will effectively absorb the X10 signals. Some common ways to reduce power line noise may also kill the X10 signals as it looks like noise.
X10's power supplies are a very low cost line derived type. A cap, small resistor and sometimes an inductor used to limit current into a few diodes, a zener and a filter cap. Some square waves or stepped sine waves can do strange things with X10 power supplies.
Power line is many times the common of the PCB. Good reason we tell users not to add wiring inside them for external uses.
