    Does anyone need a MyStat PCB and is based ln the EU? It's probably useless to most people who donct have an oven and advanced SMT soldering skills. Anyways, if you're interested, I can send one over for free.

      @sepi 😊 I have no clue how easy it is to source all the components, but would be a nice exercise. If you still have one left over...

        @czahl You can pretty easily get them on digikey or similar but there is this BGA micromodule that you have to solder in an oven I guess. The rest of the parts could potentially be soldered with a classical soldering iron if you have a steady hand. What's your equipment and experience with soldering?

          @sepi I tried soldering one of these by hand once, it didn't go well, lol. You need a REALLY steady hand and some very good soldering equipment. When you solder this by hand some pieces have really short contact points, so it is very hard to figure our where you have shorts. I got some magic smoke 😑

            yeah, I usually order at RS; there will by some way to get them.

            I'm using an ERSA i-CON and Weller 1010 since "some" years. Soldering of small footprints will be done by soldering below a Bresser 3D Microscope. I do not have a reflow oven, so the BGA will be a challenge but should be possible with my hot-air soldering station as well.

            When you solder this by hand some pieces have really short contact points, so it is very hard to figure our where you have shorts.

            You are absolutely right you have to be very careful. But I also manged to turn the 0-ohm resistor on the ESP32-cam to use the external antenna.

              @czahl You are clearly way better at soldering than I am. I have a bunch of components for a previous mystat version plus the boards, I could send them your way if you're interested in them too. In any case, keep us posted on how it goes!

                Now we only need a way to exchange private addresses. Any idea?

                    @czahl there is no failure possible from my point of view at least since I can't use the PCBs anyways :p.

                      @czahl @sepi I can view the emails you used to register, so I'll send you both an email so that we can exchange information. Let me know if you agree and I'll proceed.

                        @danielfp248 you can! Is it not possible to enable the chat plugin in nodebb or some private chat plugin if that exists? I had one other situation like this already.

                          @sepi @czahl @danielfp248 I have enabled the chat plugin just now! With min. user reputation of 2 to try to prevent spam.

                          Public and private chat groups/PMs now possible, though I don't think it's encrypted if that's a concern (we are hosted by NodeBB).
