X10 inside a car

[HarryAl]

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.

So I need to build a power grid 110 in my car
If anyone has any idea please send me

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.
