Pas Home / Final Summary

Posted by verrverr Oct 24, 2014
Pas Home - Index    Final summary demo video    State of implementation of the plan    The nagging questions that I will plan to answer with my project are:   Did I leave the curtain open or close? (Success) Did I leave the washing machine active or not?  (Not started) Did I leave the basement door open or close? (Success) What are the temps near my windows? (Success)   Original Plan in picture update   The Plan result   (1) Inc ...
Pas Home - Index  For several weeks I try to find and implement a functional version of my curtain opener. This is the progress up the final version.   Step 1  Remember the drille Pas Home / Curtain open close prototype 1 First test a made with a drill and fishing line is to test the concept. The idea is simple, copy a Washing line with pulley. One curtain is on the top rop and other on the button. When the line turn the curtaint open or close. During this test we discoper w ...
Pas Home - Index  Here are the most detailed instruction to manufacture of a very simple braket for the temperature sensor     Step 1 Cute 4.5mm acrylic clear board with a Jigsaw to made a rectangle of 3cm x 13cm   Step 2 Sand the side of the cutted restangle for good finish, i use sand paper of 60/180/400 and i finish with cutting weel with a small polish brush   Step 3 Remove the protection paper and bend the plastique using a hoot air gun. I use a small piece of ...
Pas Home - Index  The days seem shorter, I'm not sure it's just because of the sun that sets earlier.   From Proto board to ProtoShield  Last week i made a more final version of my home ventilation proto.   I use an arduino proto shield https://www.adafruit.com/products/2077 directly on the RPiSoC but with minor modif to the RPiSoC software because the shield cause RPiSoC reset loop. On the shield the ICSP Reset pin and Reset Pin beside 3.3v pin are connected an cause RP ...
Pas Home - Index  Hi, this week i finalize my proto for controlling my home ventilation. I'm not sure of the connection of the transistor.   Are the 2 diodes are useful? Is that the resistor R6 value is large enough ?   The code for the python and nodejs application controling the RPiSoC is available here https://github.com/pascalmartin/ForgetMeNot/tree/master/bundles/rpisoc And the openhab configuration here https://github.com/pascalmartin/ForgetMeNot/tree/master/bundles/o ...
Pas Home - Index    Hi small update for this week. This week a made some test with stepper motor and 2 proto to open my curtain but one proto is not very reliable and the other is very noisy and very slow. I'll make some improvements and get back with more details   I also quite progress with my proto to control my home ventilation system, i'm now able to read to current status ot the ventilation system. Now i will finalise the transitor circuit to start ventilation.   ...
Pas Home - Index  This week i continue to play with adafruit motor shield. I configure the shield to run in 3.3v mode compatible with Raspberry pi and convert the driving library in nodejs because i plan to use nodejs for easy comminucate beetween pi and other pi with open hab.     Configuring  The motor shield comme with configuration for 5v mode. The shield is made to be easily switch to 3.3v. This is the instruction to switch to 3.3v     Testing  A ...

Pas Home / Stepper motor

Posted by verrverr Sep 18, 2014
Pas Home - Index  During the last days I have do some testing and prototype with Stepper motor for opening and closing my curtains. Durant les derniers jours j'ai réaliser quelque test et protype avec les Stepper motor pour l'ouverture et la fermeture de mes rideaux       Beginning / Début  I started by following this tutorial https://learn.adafruit.com/adafruits-raspberry-pi-lesson-10-stepper-motors to control a stepper motor and then I try in rea ...
Pas Home - Index  This week the winter really begins to be felt in Quebec. With an outside temperature of 10 degrees Celsius my heating system must operate efficiently and with high availability. In a previous blog,Pas Home / 1-wire vs Tektronix oscilloscope, I present the problems in my DS18B20+ sensor network. Thanks to the oscilloscope win I could really see the problem and find a good solution. After several days of testing witout error I finally chose the simplest solution, replace t ...

Pas Home / Sensor case

Posted by verrverr Sep 11, 2014
Pas Home - Index  Hi last week i made a small proto of temperature sensor case. A little trip to the home contruction store and i buy 24x24 4.5mm acrylic clear board. With some work i made an very fonctionnal and quite aesthetic mounting support. 4.5mm is a bit too strong, a thinner acrylic also makes the job. I plan to make my curtain motor bracket with, that's why I bought the thicker.     I did not have the equipment to heat and bend the piece, so I use a lighter. His wor ...

Pas Home / PiTFT

Posted by verrverr Sep 6, 2014
Pas Home - Index  This week a play with the PiTFT from Adafruit https://www.adafruit.com/products/1601, also available on newark Product Link   I want use the PiTFT with Pi for made a control panel to install in my kitchen and easily open/close my curtain, view and change heating temperature and control my home ventilation.   Setup  This is the procedure a use to setup my device https://github.com/pascalmartin/ForgetMeNot/tree/master/bundles/pitft   Usefull tips T ...
Pas Home - Index  I will use the RPiSoC to control and catch the status of my home ventilation system. Integrate with OpenHAB and my humidity sensor, when i take my shower humidity sensor detect the humidity increase and automatically start the ventilation. I suck in electronics I'm going to need your help. The plan The timer I open the current control and check component. Its seems simple enough:       4 wire 12v, GND, LED Control, SW (Switch),   ...
Pas Home - Index  Hello, this week I did a lot of testing and debugging with the oscilloscope. I try to see and solve the problem of my network of temperature 1-wire sensor.     I try first to change my connection to the 5v and 3.3v use, I also change the cable connection together. Using the 5v is really not advise for raspberry pi but its still work reasonably well for 6 months. Result : failure no captor are detected     Then I tried to change the way power senso ...
Pas Home - Index  Great I have received the critical parts for my project. I'll do some prototype to test the opening and closing my curtains   Et voilà, j'ai maintenant reçus les pièces essentiel pour mon projet. Je vais faire quelque prototype pour tester l'ouverture et la fermeture de mes rideaux.   ...
Pas Home - Index  In my project I plan to modify an existing circuit because it has too many communication errors with the sensors. In a future blog I will try to see the problem with the oscilloscope. Do you see errors to correct? Will the new scheme all the resistors are essential?   Dans mon projet je planifie de modifier un circuit existant car il a trop d'erreur de communication avec les capteurs. Dans un blog futur je vais essayer de voir le probleme avec l'oscilloscope. Est-ce ...
