!!! FIRST AND ONCE FOR ALL !!!
I don't even claim that my information is correct! It might be.
US residents should not try any of my clever ideas. They will almost all violate your electrical codes. In fact, that is probably also true for most European contries, Australia, New Zeeland, etc.
If you don't know the difference between a cat and a polyester capacitor or if you can't handle a soldering iron, don't even think about opening a module.
Don't blame me if your house will catch fire or if your wife electrocutes herself when trying to play Duke Nukem 3D on your computer. Did you modify the TW523 computer interface?
You will definitely void the warranty if you try to touch anything inside any kind of device.
Also don't blame me if your modules explode or just fail to work. The info in this document seemed to work for me. I could have made a typo or perhaps my strange English confused you!
It is clear that some modules exist in different versions. What I try to tell you, might not apply at all! If the original values or the placement of components is different, you have to try to figure out the differences yourself.
It is also very probable that some errors have sneaked into my schematics, they are just reverse engineered to look at the power supply part so I could modify them. In some cases, I did put a little bit extra work into them just because I was curious about how they worked.
In many countries, your insurance will not pay you if the fire or accident was caused by a non approved electrical appliance. They might have been CSA and UL (Undertakers Laboratory!) approved before the modification but that is worth nothing to you! You might even end up in jail!
The radio transmitters used in some X10 remote controls work on 310Mhz and are probably not approved to use in many countries. You might be accused of having an ilegal radio transmitter or the custom might confiscate them before you even receive them.
You are on your own!
I am serious! Almost all X10 modules have very simple power supplies consisting in most cases of only a couple of capacitors dropping down the mains supply, meaning that everything inside a module has your line voltage relative to ground.
Don't think about something clever like pulling out cables from the switches inside a mini controller and connect those cables to your son's model railroad! The model railroad will have your mains supply voltage to ground and your son and his friends might die.
