      I've been using processing.org to capture data from Arduinos. I haven't tried with an RPi yet, but the link here is dedicated to just that. Processing is more geared for doing really fancy graphics, but its ability to capture data and put it to a file is great, and, of course, send data to the Arduino. I am inexperienced in interprocess communication, but, apparently processing can put the data out to MQTT check this link Let me know how that works out for you!

      NeverDie

      @NeverDie said in The Harvester: ultimate power supply for the Raybeacon DK: Edit: This guy found another couple of possibilities as to what the E50D chip might be: https://www.electroschematics.com/pfm-module-circuit-surgery/ I have the same board as this guy. I removed the LED and resistor because they are on the input side, so they are almost useless anyway. For a board such as this, with a promised 0.9v startup voltage on the input side and a promised 5v on the output side, they really should have been attached to the output, not the input, to show roughly when it is that the board is producing useable output. At a 20mv "keep alive" input voltage, the input measures 0.5ma using a uCurrent Gold. That means the keep alive energy is 10 microWatts. Offhand, for the application we've been discussing on this thread, I suspect that number is too high to be practically useful, because at only 20mv input we'd be collecting far less than 0.5ma current from a tiny panel. At least now we know.

      @Koresh I do like it, i just worry for people that use their main PC as a controller. Easily knockable/damageable unless they use a rear socket.

      Very nice! I'm planning to build a 12x12 led 40x40cm "screen" and Fadecandy looks like a great match to create art to display on it.

      Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface. ps/ Where have you gone? I have been working on "xRoom" shield. A small announce: Do you remember the discussion about multinode? So, it will be available soon))

      @GertSanders it is so small indeed, soldering with my soldering iron would be a problem. Maybe a 'secret' connector for this device would help @Koresh, just mount it if you need it...

      @MiKa Hi. oki, in case i'll add some explanation.. I'll be busy for this week but you can simply use the serial gw example from MySensors for getting started, this should work. I didn't need to create a special board in arduino for this board, so if you're using it, you'll need to install&use the mattairtech SAMD21 board definition for the pin mapping. https://github.com/mattairtech/ArduinoCore-samd

      Actually, I use the FTDI connector on my outdoor weather sensor to power it from the solar/Li-Ion charger board. Used angled headers to keep the height down. I'll try to post a picture asap.

      @tbowmo more out of curiosity, and from someone that just got started on electronics, so please sorry if this sounds like very noob, but, would it not be safer to plug the V_TARGET LED to the +3.3v pin? How do you ensure that the resistor on the V_TARGET will have constant voltage and that will not blow from over voltage if the VCCio pin is depended on the the Motherboard power? Thank You and nice work
