    • Ultrasonic essential Oil diffuser

      Hi,

      my wife like to use essential oil in the house, but basic humidifier use a lot of water and increase the ambiant humidity in the room.
      I notice also that the smell of the oil is not really intense.

      So the idea, modify a cheap ultrasonic humidifier and create an oil diffuser without dealing with water.

      The start, a cheap Donut humidifier 6$ on ebay.

      http://www.ebay.com/itm/Donut-Shaped-Ultrasonic-USB-Humidifier-Air-Essential-Oil-Purifier-Aroma-Diffuser-/301652283655?hash=item463be09107:g:vrwAAOSwBahVbrHo

      then, I decide to build a wood enclosure with a removable top for easy oil bottle changing and put everything together.

      0_1456867650174_20160301_220334.jpg

      The top is maintain by 2 small magnet, and the ceramic caps just touch the top of the Bottle wick.

      Regarding the Sketch, Its like a dimmer, V_status for the On/Off state, V_percentage for the frequency.

    • Your Multi Room Audio System

      Hi Everybody,

      This thread is not related to Mysensors, but I would to take advantage of having great comunity to share idea arround Multi Room audio.
      My original idea was to have abilities to play any music anywhere with a multi room option.
      My goal was to have this for a good price without sacrifice the sound quality.

      After some reseach I decide to go with the Squeezelite environement running on a Pi, and adding an I2S audio Dac.
      it was pretty straight forward, and tons of tutorial available did helps a lot.

      • On the main room, I wanted to have a powerfull speaker with a touch screen interface to manage all speakers.
        So I build mine, and after couple of hours a woodworking I get something like this:

      0_1464876239129_2016-04-10 18.42.09.jpg

      0_1464876253767_2016-06-02 15.55.38.jpg

      I'm very happy of this "Main" speaker. it work like a charm, it run a modify Raspbian for touch screen support, and squeezelite/Jivelite.
      So after that, I wanted to have smaller version for all others rooms.
      I decide to buy some cheap bluetooth speaker and add a pi inside with a Dac.

      0_1464876546266_2016-06-02 16.07.07.jpg

      Small speaker satisfy me also, they run PiCoreAudio, the sound is defenetely worst compare to the main one, but it's really acceptable for me.

      Regarding the budget, all included the main speaker cost me less than 100€ and the small one 50€ each. Very cheap for a multiroom solution that can be control by any device included the Home Automation Controller.

      So next step could be sound input for the voice regonition.
      Did you guys have some background on it ? I would like something very responding and I don't want to use any external STT engine.

      I read some post regarding the Jasper project. what do you think about it ?
      Regarding sound input do you suggest special mics ? is any STT engine exist with Client/Server mode ?

    • RE: Ultrasonic essential Oil diffuser

      Hi,

      It's hard to say right now.
      It can be interesting to know how do you control the On/Off.

      Those Ceramic caps don't like to be used without any liquid and can be damaged very quickly if there are dry.
      But normally there is a build in switch off circuit if no liquid is detected.

      Can you tell me more how to you modify the electronic to control it with Mysensors ?

    • RE: Motion Sensor triggering on its own

      Hi,

      False detection is only due to power stability issue.
      Personnaly i remove the regulator and power the PIR without any boost on the VCC pin. Even below 2v the PIR continue working without any a single issue.

      Did you try to do a small delay before sleeping with interupt ? See my post a bit upper.

      For me it solve all my false trigger issue.

    • RE: Microwave Radar Module as PIR replacement.

      That's may change a lot of things, in term of power consumption, enclosure, sensor position in the room.
      Will order one right now.

      Thanks for the find.

    • RF documentation - "Best practice"

      Hi,

      For those that interesting to build RF circuit, I found a very good article with an 1h video showing very good trick to build a RF circuit.
      HackaDay fan, has certainly not missed it 😉
      The nFR24L01 chip is mention.

    • RE: Motion Sensor triggering on its own

      Hi,

      i'm wanted to share my experience also with those sensor.
      I had a lot of issue with false trigger when running on 3.3V. In my case the power was definitely the issue.
      it's looks like sleeping the radio/mcu cause some noise on the voltage line.

      I solve 100% of my false trigger issue when doing a small sleep, before enabling the sleep with interrupt.

      gw.sleep(500);
      gw.sleep(INTERRUPT,RISING, SLEEP_TIME);

    • RE: Ultrasonic essential Oil diffuser

      @gregl yes, I think about add a level indication by using a simple ldr and a led, shouldn't be complicated to archeve.

      regarding the ceramic caps, a lot of them you can find on ebay use 40 Vac at 1.6Mhz. so not so easy and finding a 8:1 transformer working at this frequency to make a small DC to AC converter is not that easy.

      after some search, I find some other caps like exactly the same there is on this "donut" humidifer. they are working at a much low frequency, 113khz to be exact.
      http://fr.aliexpress.com/item/20mm-113KHz-ultrasonic-atomizer-transducer-atomizing-part/32273063940.html?spm=2114.44010308.4.177.0Amsoy
      Regarding the voltage, I found some caps working at 5vpp but the donut caps seems to working arround 50v.
      I don't have any idea how they boost the voltage to that pick.

      here is some scope:

      Mofset Gate :
      0_1456920546860_IMG_006.BMP

      Caps input:
      0_1456920582586_IMG_001.BMP
      the sinus wave it's really durty, but seems to be enough to vibrate the caps.

      donut IC :
      0_1456920732712_20160302_130545.jpg

      0_1456920737957_20160302_130603.jpg

      if someone have some idea of what is this black component on the right side. seems to be the one that boost the voltage up to 60v.

      @tripy yes everything handmade. my friend carpenter help me to glue together some piece of wood plate like this : http://planete-bois.com/plans-de-travail/28-plan-de-travail-chene-lamelle-colle-aboute.html I manage the rest with a router and a drill press.
