    @petewill when you start home automation at that time please share photos wit me.
    how to setup the no. of relay, power supply, arduino, radio etc in WALL box.

    @jemish yes, that's the plan. Once all the geniuses figure out how to do it I plan on making a how to video :)

          @Didi, did you end up doing horrible things to these? You said something about flashbox?

            If the fellow behind http://lygte-info.dk/info/usbPowerSupplyTestHow UK.html posts good results on his website, the supply chain should prepare for a flood of orders! I've seen those tests widely referenced, and I think a lot of people are looking for something safer but still cheap.

            Don't be surprised if a positive review made it to HackaDay and the like as well.

            (Get your ali orders in now, beat the rush - if you think it will come out well)

              I'm also looking forward about test results. I've seen the module however never totally trusted; until I found this topic. The price and size are perfect for under-socket installation. If further results come out good, I'm eager to see in-wall projects.

                This one is not "safe", but it is an In-Wall AC to DC converter. Transformerless. With a 3A Solid state relay:

                2015-08.jpg

                The converter output is 3.3V at 100mA and the solid state relay is a Triac.

                  Looks very nice, but you cannot use it for sensors or actuators that can be touched by hand and do not comply with the insulation standards, since parts of it will be connected to mains.

                    @Bertb Yes, it shouldn't be touched. It can be used with wall-mounted mains switches, though. Placed behind it.

                      Did anyone look at the SwitchMote PSU over at LowerPowerLab? More info here. The kit is fairly expensive ($30) but I wonder how much it would be to source the components yourself since someone else has done all the design work.

                        @TD22057 I would say the cost of this PSU is dominated by the Recom converter onboard. Farnell charges E14,58 for single pieces (http://nl.farnell.com/recom-power/rac02-05sc/ac-dc-converter-2w-5v-reg/dp/1903060?searchRef=SearchLookAhead).
                        Rest of the components will be a few Euro's, and ofcourse the PCB (which contains a number of milled slots for isolation).
                        All together you will get fairly close to $30 when building it yourself.

                          Nice! just label board !LIVE!

                          Not safe due to no fuse? Do share, making your own boards with solder mask?

                            @DrJeff the board is not isolated from mains by e.g a transformer. This means traces carry live mains!

                              So basically it is like any other consumer Zwave switch or X10 just box it up (3D printer on stand by) with 2 micro buttons with a rocker face and I want 10. :) But sorry I digressed from the OP in my excitement.

                                @DrJeff As @Yveaux said the board does not have an insulation transformer. Yes, I make them. And it works fine, placed inside an enclosure is as safe as it could be. Would you make a box for it? I can send you one board if you like, for the measures.

                                  @ceech Yes I like the idea of course the board would be housed inside of a box, my idea is to incorporate the box with a daughter board with 2 push buttons on and off like Zwave switches use. Yes please send me, if you are worried I will use safely I was taught to work on all power 120v - 480v as if it is live so that you remain alive!

                                      Another China iphone plug destroyed.

                                      This has been working for 2-3 weeks without problems... the plug runs a 5v arduino and a normal 240-5v relay with button and led, standard sketch.

                                      One day it just didnt started and i opened it up and saw a melted plastic cover and some burned component.
                                      I have felt the relays a couple of times and noone has been really hot.

                                      20150826_205836.jpg

                                      Im getting a bit shaky here... how far from disaster (big fire) is this?
