Home Automation Domotica Forum Europe, Bwired Forum

I would like to bring this discussion back to where it started:
The commercial passive x10 filters commercially available in EU are very expensive for what is found in the package; a few coils, some capacitors, a resistor maybe. It's been designed of course and the plastic house will cost some.
But 60 euro's for 2 euro's worth of electronics?

The filter itself is supposed to be a notch or band-stop filter, that's all.
As far as I can judge the above mentioned design is one, there are other designs too. What's missing is the actual values for the various parts.
Did anybody ever measured those coils?

Also, I checked:
http://tonnesoftware.com/elsie.html
Using Elsie you can design various fairly simple filters that should or could do the job.
I have no electronics background, but it seems straightforward. Anybody ever tried this?

It would be nice and rewarding to build your own wouldn't it?

Is this off topic?

Yes, of course FM10 filters and work great, but after #14 FM10-filters my budget has gone.

Perhaps there is an other solution: XPRN noise reduction.

I did not try this.
But the are Cheap and you can put them in the case of an appliance (e.g. TL-armature).

9.99 usd, it means cheap and simple construction ! is it good for european 220V too?

Hi Lorenzo, I wanted to attach a Help in .PDF but that is not allowed.

You can find the usermanual here: http://www.thehomeautomationstore.com/xpnr.html#
Under the TAB: SPECIFICATONS.

Yes, you can use it on the 240 Volt system.

Hi Verkenner, That's kind of you Thanks for info

Looking good but might be a challenge toe build in with these dimensions 1.25" in diameter, 2.5" long (31,8mm x 63,5mm)
