    Default d.i.y. x10 universal module

    See picture,

    I needed a **quiet** x10-controlled relay

    I purchased the UM7206 universal module, but the bistable relay inside is **extremely** loud.

    This thing is an alternative, but it's expensive (in europe) :
    and I only needed one relay contact.

    This one is lower cost...

    soooo, I built my own, using the same XM10 TTL Interface (TW523 in the USA) as above devices also require...

    The device is based on a PIC 16F84 processor and a 5V reed-relay that I had laying around....

    If anyone wants it, I can publish the c source code for the pic processor (c compiler used :

    the code is modified from this :

    (p.s. the reed relay is connected to my central heating and will allow girder to control the room temperature without using a thermostat)
