    I am going to fabb up something as a project.
    I was in a KS campaign and got one delivered that works great, but since those are not generally available I figured a kit someone can build would be helpful. Particularly if you want unattended printing,

    http://www.amazon.com/Smoke-Sensor-Module-Detector-Output/dp/B008MSQO0W
    or
    http://www.amazon.com/Kidde-SM120X-Detector-Hardwired-I-Combo/dp/B001AYERC2

    would be a starting point (leaning towards the first one). Then a remotely mounted though power connector and some printed parts to mount it all in.

    Stay tuned.

    Sweet, I was going to ask you what sort of options there were for that.

    Slow boat from ...China :)

    I will start this as soon as I get the sensor.

    OK, the 'guts' for this arrived and (funny) are identical to the KS version I bought. It is only missing the external control board.


    So, time for vote...
    Who wants this to be 'wired' where a cord attaches the sensor to the control relays and who wants this 'wireless'?

    It would be easy enough to do both. The wired would be a lot less electronics construction (so probably easier) but wired means you need to have a wire between the two (the sensor and the control relay)

    I'd rather it be wired

    OK, I'll do both.
    The wired is really, really simple.

    The wireless is a little more expense and a tiny bit more complicated so I will do it second.
    It does add the possibilities for some cool stuff if I toss in an Arduino board. Overkill though :)

    if you can have it send you a text when smoke was detected that would be sweet as well

    That is easy enough to add with the Arduino board. Thanks for the idea !

    These are the parts so far. Additionally there will be two printed boxes (cad files and STLs forthcoming) one 9v battery and one extension cord sacrificed to the cause :)

    oh, and one network cable of whatever length you want to separate the detector and actuator.

    This is the wired version. The RF version will be next (once I finish this one).

    The actuator will be rated for up to a 30a load which will easily cover the printer (or two).

    One other part.

    20151018_092946[1].jpg

    I will start detailing the build when all of the parts are all here.
    This will be the power strip ($5 at Home Depot) that we will be converting for control by the smoke detector.
    If smoke is detected then this strip will power down.

    The 'smart' one will be using an Arduino to control it, not sure which one at this point.
    I was leaning towards the ones from www.tiny-circuits.com but they don't have a relay output and for this that is the easiest way.
    I could use their breakout board and build one, but that is a lot more effort. I have used their stuff before and where it works it is amazing.

    A Mini perhaps. Worst case a full sized Arduino Uno, but I think I can avoid that :)

    We'll see once I dig into that. The 'dumb' one is first.

    Parts are still trickling in on this. Should have the last of them by Dec 2.
    Rather annoying that it takes so long to get some of this :)

    I may have all the parts for the 'dumb' version sooner :)

    OK, I think at long last all of the parts are in. Will be working on this over the weekend.
    Dumb version first as promised.

    While my son is finishing the CAD for the case on the dumb detector -- DD ... I guess the smarter one will be model SD :)
    I was researching the connectivity for the SD sensor and Arduino/Controller. I am still going for the cheapest solution so simple RF transmitter/receiver cards are what I am starting with (they come in various ranges, I am going with the 433mhz). The range on this will be really decent (better than bluetooth and cheaper) and can be extended by making the antenna longer. This also will use an Arduino on both units (sensor and actuator) so the potential for expansion here is quite large.

    Still looking forward to posting the build details for the DD later today, it is just about finished. Like the one I got from kickstarter, the DD will require a cable connecting the two sections (the plans I am providing will use an ethernet/CT-5 cable).

    My goal is to keep the DD as simple as possible so anyone can build one.
    The SD will be a flight of fancy and I anticipate a lot of extra over complication on that one "Just Because We Can".

    CAT 5 cable will connect sensor and actuator. Reset button is there as well.

    ALL STLs and SolidWorks files will be included as well as a description of how/what you might want to tweak.
