    • My sensorboard MYS 1.0beta

      Original thread got lost in the forumcrash.

      I have made a sensorboard that is under testing.

      spec:
      socket for arduino pro mini 5v/3,3V
      socket for radio
      3,3v regulator
      4 AD input with voltage dividers
      7 gpio availble with pullups on all pins

      IMG_0128-225x300.jpg

      I have som small mods left to do in the voltage dividers.

      Is there any interest in boards or kits (board + components) for just a few dollars?

    • RE: PCB design and production

      @Vodden how large is your enclosure?
      I am working on a daughterboard for my mys1.1 with 4 channels of pwm and current measuring on each channel.
      each board is 50x50 mm stacked on top of each other.

      I now have 300 boards on my desk and have set up an online ordering system on my page http://www.sa2avr.se/mys-1-1/
      After a discussion with @hek have I also released the board files for mys 1.1 on my page.

      @n3ro Hi all caps and resistors are 0804 size.

    • RE: irlz44n not fully open using 3.3V Arduino

      Many mosfet does not open fully on 3,3V. You have to check graph in datasheet when choosing mosfet.
      You can pull gate high with a resistor to 12v and use a npn transistor to pull it low.
      But that makes it default on. If sensor node fails all leds will be at 100%.
      My ledmodule uses IRLR2905 and is powered by a 5v promini.

      Maybe look at AI-thinker A6c module that has direct camera interface and sends pictures as MMS over GSM.

    • RE: Driveway Alarm / Vehicle detection

      Maybe you could use an ultrasonic distance sensor to detect if anything is in its measuring range?

    • RE: MAX6675

      If you are not going to use mysensors look at library example

    • RE: MAX6675

      example has to be converted to 2.x of mysensors.
      To do so you need at least to add
      #define MY_RADIO_NRF24
      remove all gw.
      please look at any 2.x example to see what have changed.

    • RE: MAX6675

      @Ezequiel-Torres I did just connect pin 3,4,5 and vcc,gnd to module and sensor to module. Look in example code for directions.
      Example is made for mysensors 1.4 or 1.5 so may have to modify it a bit.

    • RE: [SOLVED] upgraded to Mysensors 2.0.0

      I am also in the same process of upgrading my sensors and have also seen this behavior (not finding parent node).
      First I thought the radio was broken and changed radio. That got it going but the problem came back. Then I realised that problem comes from resetting the node and not turning power off completely. I had to disconnect my USB-serial adapter and power to make it work.

      Anybody wanting 10 kits at a bargain price. I am sellling them at bargain price due to lack of time to play with them.
      If you are in Rome I can hand it over directly . If you are at EU maker faire this week end even better see you there.
      Otherwise I ship them too

      KR

      Still got the 10Kits?

      You can still buy these kits from my homepage.
