New Central heating boiler

Today we have fitted a new central heating boiler a few months worrying in malfunction by the now 10 year old Nefit Smartline HR/ C24/CW4 Basic Combi.
This combination boiler has so far done with minimal maintenance (1x DIY cleanup and replacing ionization pin). In recent months suffered from 3L failures, this probably means a new fan a € 280 and you have to assemble it yourself. But it could also be a burner controller UBA a € 200 according to the people of Nefit. After a lot of information gathered from forums, neighbor installers or the like, I decided to replace the boiler.

By the men of Warmteservice (good parts store) made an appointment with an installer that installs many Vaillant boilers with 12-year warranty on parts. The choice fell on the energy efficient Vaillant ecoTEC+ (2x in a row "as best tested" by the Consumers' Association) and costs of installation and guarantee about € 1,500 (€ 100 cash back by Vaillant), but then you get some!
Model: CW4 VHR 25-30/5-5) energy class A is for heating and hot water (14.3 l / min at 40 ° C), quiet (46 dB) and hopefully little failures.


The Honeywell Chronotherm IV I replaced by the Vaillant calorMATIC 370 (black / SS) that operate very easily by hand with a large knob or weekly program and modulating connected to the eBUS of the Vaillant boiler.
The old boiler and thermostat I sold on Mark Place respectively 100 and 30 euros

    Arduino projects

    I'm now developing a number of weeks to Arduino projects (and Chinese clones) and already acquainted programming with different components. Various sensors (temperature, humidity, light intensity, water level, soil moisture etc.) connected with mini LCD screens, leds or an iPhone App . A stepping motor, mini servos, relays, LEDs, ultrasonic distance meter, alarm clock, data logger with SD card, WiFi module, Nano etc. I learn and apply combining for future projects.
    Coming weeks there are orders with an Ethernet shield, Bluetooth module, the Arduino Mega, pH sensor, a mini-laser, barometer and more components.
    The hobby / study room has been cleaned up nice and technically equipped to develop the electronics projects. Many basic electronics I make my own and I purchased a fine soldering iron with ceramic element and adjustable temperature control which I practice to learn to solder properly.







    Controle met Arduino

    De zeer handige link naar Wforum, de Getting Started en mooie voorbeelden.
    Op YouTube zijn er ook talloze voorbeelden: zoek maar eens op arduino gardening.

    Doel:
    Ik ben nu eerst aan het bepalen wat ik er eigenlijk mee wil?:
    1. Allereerst leren, dat blijf ik altijd doen, beginnen bij het pielen met ledjes e.d., programmeren etc.
    2. Controle kweekhok (diverse temperaturen, RV, grondvochtigheid, pH, EC handmatig en op het web) en eventueel later ....
    3. Automatiseren (bijv. irrigatie, voedingscomputer te besturen vanaf het web of een app).

    De Parrot Flower Power heb ik dit jaar gebruikt bij de buitenkweek en dat beviel me erg goed. De 4 sensoren in de Flower Power geven data door aan een app op de iPhone. Ook wordt er een webpage met grafiekjes aangemaakt, erg leuk allemaal.

    Open Garden heeft een zeer complete Arduino shield (gateway €60) voor sensors eventueel aangevuld met hydroponics shield voor pH, EC en Temp (Kit: €200). Je kunt hiermee gemakkelijk een compleet controlestation maken met losse nodes per plant (€100) en controle via web/app. Ook Waspmote is zo'n sensoroplossing. Dit lijken mij allemaal prachtige systemen alleen veel te duur voor mij, dus ga ik een Arduino systeem bouwen en programmeren met losse chinese onderdelen van eBay of AliExpress.

    Komende maanden wil ik me focussen op het controleren (en later ook automatiseren) van een semi-hydro/dwc kweek, dwz kleine kast met 2 planten in potten die boven waterbakken hangen.
    Naast de temperatuur en luchtvochtigheid in de kast bij de planten, wil ik o.a. de temp van de waterbakken gaan loggen en bloggen, later aangevuld met pH, EC en misschien DO? (dissolved oxygen)


    Mijn eerste Arduino project: 

    Controle van DWC-ontkiembak (5 liter waterbak met met bubbels)
    1. Temperatuur waterbak monitoren (DS18B20); schakelen 7W-warmtematje (onder de waterbak).
    2. Temp en RV in de propagator (DHT22: €3,10)
    3. Timer voor lampje 11W (RTC-module: €0,85)
    4. Webserver/app
    5. Waternivobijv. met (fuel)vlotterschakelaars, DIY Capacitive Liquid Level electrodes of Ultrasoon (mijn voorkeur))
    6. Luxmeting (BH1750FVI)
    7. pH-waarde
    8. EC-waarde


    Arduino projecten toekomst:

    • Pan/tilt webcam (CM210 HD720 met mini servo's €30-35) 
    • Automatische lichtarmatuur hoogteverstelling (ca. 5 cm boven de planttoppen, zodat deze niet tegen de TL's aangroeien)
    • Digitale tensiometer (DIY)
    • Voedingsdoceer unit DWC
    • Automatische pH-regelunit DWC

    Concert Steve Hackett - Acolyte To Wolflight

    fryday Oct 2, 2015

    20:30h  De Boerderij

    Steve Hackett bracht in maart zijn nieuwe album Wolflight uit.
    Op 2 en 3 oktober 2015 is Hackett live te zien in Cultuurpodium Boerderij in Zoetermeer.

    Deze show omvat een groot deel van Steve’s solo discografie, een selectie met solo materiaal waaronder nummers van albums als ‘Voyage of the acolyte’ (1975) ‘Please Don’t Touch’ (1978) en Wolflight (2015). Natuurlijk komt ook het materiaal van Genesis Revisited ruimschoots aan bod. De band bestaat naast Steve Hackett uit zanger Nad Sylvan, toetsenist Roger King, drummer Gary O’Toole, saxofonist Rob Townsend en Roine Stolt (The Flower Kings) op bas en ‘12 string guitar’. Wolflight is de opvolger van het album ‘Beyond The Shrouded Horizon’ (2011) en neemt de luisteraar mee op een reis door de ruimte en de eeuwige zoektocht naar vrijheid. De legendarische gitarist kijkt er naar uit om het laatste hoofdstuk van zijn carrière toe te voegen en samen met zijn loyale fans zijn muzikale evolutie te beleven.

    Basic Electronics and Arduino Tutorials

    Ohm's Law - The basis for all electronics and electrical calculations is Ohm's Law (I=V/R). If you remember this, you can figure out what size resistor to pair with an LED, how to control the speed of a motor, how to build a power supply, and more. It's that important. There are three main variables in electricity, (I) current (amps), (V) voltage (volts) and (R) resistance (ohms). There's also a 4th element, (P) power (watts). Ohm's Law says that if you know two variables, you can calculate the third. - Online Calculator

    Power vs. Energy - DC Watts = volts * amps is important, especially in solar and battery calculations, and the time element, hours, is critical. A motor that draws 5 amps, is drawing 5 amps (power) as we speak. In one hour, it will have consumed 5 amp hours (ah)(energy), in two hours it will have consumed 10 ah. When multiplied by the voltage we get watt hours (wh). This (wh) is called Energy. Energy is what you get billed for by the Power company (kWh). Watts without time is called Power. Many people get this confused, and some websites deliberately muddy the waters to make their products sound better. If you see things like amps per hour, or watts per day, run away.

    Not to confuse things too much, but in Alternating Current (AC), it's not quite this easy. It starts out the same, Watts = Volts * Amps, but we also have to divide the Power Factor. A resistive load, like a heater, has a power factor of 1, so 1200w / 120v = 10a / 1 = 10a is the same as the DC calculation. But a electric motor, computer or fluorescent light may have a power factor of .5, so 1200w / 120v = 10a / .5 = 20a. That's a much higher load, so wires and generating capacity have to be increased. We often use VA for some calculations instead of watts. You'll see transformers rated in VA, as the load power factor isn't known by the manufacturer.

    Wire Sizing Calculator - Enter the voltage, number of amps, and the distance you need to run, experiment with different wire sizes until you get a 3% or less voltage drop. It's at the bottom of the page

    Arduino
    I have gone through many online Arduino tutorials and video's, but some of the best I've run across are the ones at Adafruit. They explain what electronics components you will need, how to connect them, and how to write the code to use them, in a simple to understand and building block style. Basic electronics theory and programming theory is explained along with practical examples. Each tutorial builds on what you learned previously.
