Nursery Furniture Buying Tips

Purchasing nursery furniture requires. There are a number of factors to consider including style, material, and structure.
Have you ever had trouble choosing nursery furniture items that fit your child as well as complement the stylings of your home? You are not alone; most parents find it daunting to choose the nursery furniture items to blend well at home. Every home has a certain motif or theme, and the right nursery furniture should be able to address this.

Choosing the right nursery furniture for your young ones is similar to buying regular home furniture. Granted, there are tons of choices in local furniture shops as well as online. To save you time and effort, you should first learn about the different types of furniture for babies.
There are suitable types of nursery furniture fit for certain ages and behaviors of babies. For newborn babies, who tend to settle in one position, small cribs and basket-types are recommended.
There are stationary cribs as well as swinging cribs that suit month-old babies, with the swinging variant being more popular as it can help soothe the baby to sleep. However, this type of nursery funrniture is not suited for active babies; instead choose the bigger cots to allow your baby to move around freely without the risk of injury.

Cots are versatile not only in design but also in function. Make sure to choose cots that have non-toxic clear plastic teething rails since babies like to nibble around. Cots can also be equipped with castors (wheels with locks) to help move your cot around easily. The typical cot design is similar to those of cribs with rails, but there are also bigger designs with removable rails to convert the cot into a bed, which is suitable for at least 2 years onwards. This is the perfect kind of cot for those who want their cot beds to have a longer life-span and skip buying another piece of nursery furniture over time.
Aside from bed-types, you should also consider purchasing special closets and changing tables for your baby. Closets or chests with at least 3 drawers can do wonders in helping organize your baby’s items and necessities. A decent changing table is also advantageous to keep your baby comfortable during diaper changes and at the same time make it convenient for you.

In terms of the design and color scheme, you can always apply linens or mattresses to complement your surroundings. Natural or painted wood schemes are popular choices for nursery furniture. As much as possible, choose the former as the latter has the tendency to be hazardous to the infant’s health.

Whether you are sleeping alone or having a partner, it's essential that you choose the best size bed mattress to provide you with just as much room as you possibly can.

What must I consider when choosing the right size my new bed mattress set?

For Grownups

• The bed mattress ought to be more than the highest person who definitely is resting on it and wide enough to ensure that the individual has enough space to lie within their natural resting position without reaching past the fringe of the bed mattress or perhaps in the situation of couples getting their elbows or knees touching. For couples, we'd recommend a Full or King.

• The closer you're able to your lover, the higher the opportunity for motion transfer in addition to warmth transfer which could disturb your peaceful sleep. Bigger sleep surfaces reduce these factors

• Consider your way of life needs. Would you expect youthful children or family pets to become listed on you in the mattress? If that's the case, additional sleeping space could be needed.

For Youthful Children

• Consider the amount of time you hope to keep the bed mattress before changing it. You need to choose a bed mattress that the child can come to be rather than outgrow.

• Remember to the element in occasions where you may want to spend some time in mattress together with your child, for example, nighttime blood pressure measurements and comforting periods. If space permits, we recommend a complete size.

For Teens

• Remember fundamental essentials growing years so anticipate the development spurts and choose a size they will not outgrow.

• It's likely homework and focus time is going to be put in mattress in addition to games

• The child is going to be off and away to college inside a couple of years, therefore the room might be converted to a guest room. If space permits, we recommend a complete size

For Guest rooms

• Consider if couples are going to be while using the mattress. If that's the case a complete size with proper edge support could be needed. If space permits, a full could be suggested because most couples sleep in full sized beds. Your visitors will appreciate the additional space and also have a more peaceful stay

• Anticipate that you simply might be oversleeping the guestroom occasionally. Respite from a snoring or restless partner, or occasions where youthful children came set for comforting together with your spouse.

• Children's overnight parties where multiple children could be over sleeping the mattress

Welcome Arduino Due: The Most powerful Arduino Board

Now Arduino got more powerful and memory ... with the release of Arduino Due, Arduino community proved its active contribution to open source community.

ArduinoDue_Front

Let's have look at our newborn Arduino Due

How it Differs from Other Arduino boards?

Arduino Due is the first ever Arduino board which comes with powerful 32 bit Atmel SAM3X8E ARM Cortex-M3 Microcontroller, Unlike its predecessors which all made up of AVR Microcontrollers.

The Memory has been considerably Increased from the previous boards, It comes with 96 KBytes of SRAM and 512 Kb of Flash Memory ROM.If you compare it with Arduino Uno it has 16 times increased ROM Memory and 32 times the increased RAM.

Clock Speed has been Increased to 84 Mhz which is the fastest clock of all the Arduino boards.

Unlike other boards Operating voltage of Due is only 3.3 volt, If you prefer to give 5v or higher voltage to I / O pins, than chances there to burn your new Arduino Due.

In Arduino Due, there are two USB ports are provided, One is native USB port for providing power and other for Programming, It is called Programming port.Though you can program it with both the ports it is highly recommended that you program using Programming port , due to some slight changes in the way sketch is uploaded to the microcontroller.For more details read the official documentation here.

DueUSBPorts

Arduino Due ships with USB over current protection system, which is made up of resettable poly fuse that protects Due from higher current flow through the USB port.The threshold current is 500mA above which fuse will get a break.

Pins ... Pins ... Lot of Pins

Well, really Arduino Due comes with a lot of pins which really makes easy build complex projects. Let's see about some Pin configurations.

54 Digital Pins - Digital I / O pins from o to 53

Really, It is a huge number, 54 digital pins can use as both input and output which also has internal pull-up resistor of 100 ohms, by default it is disconnected.Al pins operate at the voltage of 3.3V and provide a current of 3mA or 15mA.

12 Analog Input Pins - A0 - A11

Each Analogue pin comes with 12 bits of resolution, which is a range of 0-4095.By default, the resolution is set to 10bits and you can change this using Arduino functions.

8 Serial Pins: Due comes with 4 pairs of serial pins

Serial: 0 (RX) and 1 (TX)

Serial 1: 19 (RX) and 18 (TX)

Serial 2: 17 (RX) and 16 (TX)

Serial 3: 15 (RX) and 14 (TX)

PWM Pins: pin 2 to 13 - You can use Digital pin 2 to 13 as PWM pins

Inbuilt LED is attached to pin13.Since pin 13 is also a PWM pin, It is possible to dim the LED.

New IDE, Arduino 1.5

The older Arduino versions can not be used to program Arduino Due, due to the changes in Microprocessor.You can download new Arduino 1.5 here.

As we know Arduino is an open source platform, So they have also released the schematics of Arduino Due, Here are some download links

EAGLE files: arduino-Due-reference-design.zip

Schematic: arduino-Due-schematic.pdf

Come on let’s celebrate Electronics…!!!

From the time of Adam and eve, humans had had an inquiring mind and result is the world in which we live.

Every time when a "why" or "how" or "what" question had been raised, it leads to invention or discovery of something new. Thanks to first citizens who helped us to reach this status of technological advancements.

After getting a stunning response from Techiestuffs blog readers over a couple of Articles based on Arduino, One day, Vivek asked me why do not we initiate a new blog on Electronics ???

So, that is what this blog is going to be about. An exclusive blog dedicated for Electronics !!!

This idea was not our idea but it was yours. You helped us to be inquiring and the same phrase "why do not we" made create this page. So, this place is all going to be yours and absolutely by you.

You are free to share anything and everything related to Arduino and its programming, give and take tips, put on new project ideas, Get your projects to thousands of enthusiastic readers and let's propagate the ideology and philosophy behind open source hardware.

Make your infinite thoughts flow and fill this blog with infallible texts.

Note from Vivek:

"Electronics", the word which fascinated me over the years and which I hope will continue to fascinate me the years to come, In fact my first blog post was about Electronics and I get into the world of blogging through Electronics. But Lately I devoted most of my time to learn about computer technologies and programming languages, which kept me away from electronics, So thought Now is the perfect time to dedicate some time to blog about electronics.

My primary intention of starting this blog is to provide unique and valuable resources related to open source hardware like Arduino and other popular proprietary learning boards like Raspberry pi and Beagle board, but that's not the end. Here you will also get to read about ever changing field Electronics on different verticals and articles to enrich your basics of electronics.

To further enhance your experience with this blog I decided to arrange various Giveaways regularly, So get ready to receive our Gifts.

You can instantly get to know about various offers and articles published by subscribing our newsletter.

I thank my friends Anand and Vinod who helped me to launch this blog.

Note from Anand:

The miniaturisation of size and maximisation of the application has made me accustomed to Electronics. Imagine what all a small chip can do ... this captivates me and forces me to go in further depth and keep on exploring.

Electronics is ruling the present world and my instinct says it will dominate in upcoming future also. I have devoted some time to get close to the Electronics and learn something and now it time that I go full fledged. I usually write blog articles for freecircuits.org and share whatever I learn.

In the process, I came to know about the Arduino board and started using it. This open hardware board is uniquely designed with vast applications. With a few programming skills, you can do whatever you wish. I am going to share the projects and experiments that I did with this board, thanks to my friend Vivek for initiating such a blog and providing me with an opportunity to share the stuff.

How to use Digital Multimeter ? – Noobs Guide

Electronics is a subject where you need to do a lot of practical kinds of stuff than to just learning the concepts, techies tuffs that are the reason I am presenting this article than teaching you about maximum power transfer theorem is or method calculate the Thevenin's resistance. (Please go through the book The Art of Electronics if you do not understand these terms).

Techie stuffs

Digital Multimeter is an extremely basic Electronics Tool that each Hobbyist and learner ought to have because this is the very first tool which can help you to understand the basic Electronics.

The multimeter is an Electronic device which helps you to measure various quantities like Voltage, Current, Resistance etc.In this article, I am going to demonstrate all those stuffs that you can do with a Multimeter.

Anatomy of Multimeter

Multimeters are available in various range based on its precision and extended features to measure several other physical parameters like Capacitance, Inductance etc.You can buy Multimeters on various online stores such as Amazon.

In this article, I am using the basic one which has capabilities to measure Current, Voltage, resistance and to check the continuity.

Anatomy of multimeter

As you can see in the above Image, The multimeter represented here is have 3 digit resolution, which is enough for a beginner or a Hobbyist.

Inorder to measure the specific quantity, you need to set the knob to the corresponding range, If you are unsure about the range then start with the lowest possible range.If the reading in the multimeter shows '1' then it means the value is overflowed so you need to move the knob to next higher value.

Now before moving on further, I would like to mention about the Try it exercises block below every experiment, these small experiments will let you think and explore deeper to what you are learning.So Please do not skip the Try it exercises.

Experiment to Measure Continuity of a material

Continuity is a physical property which represents the materials ability to conduct current through it. The continuity test will be helpful in many aspects such as verifying Soldering joints and to debug the circuit for broken wires and pins.In fact, most hobbyist mostly uses Digital multimeter to test continuity only.

Let's see how to test continuity

Connect the Black probe to COM port (Common).

Connect the Red probe to V (mA) port (for measuring small current and voltage)

Set the position of the knob to Continuity test mode. (Refer the below Image)

Place the Black probe and RED probes in two ends of the material that you wish to test the continuity.

Now if you hear beep sound then, the material you tested is a conductor and if it does not make beep sound then the material is not a conductor.

continuity-test-multimeter

[Tryit] Try to short the two probes in continuity mode, what did you observe? [/ Tryit]

Now test some other materials before you move further.

Experiment to measure the Resistance of a Material

I hope you understand what resistance and resistor are, So I am moving on to the experiment directly.

Connect the probes as mentioned in the previous experiment.

Set the knob to Resistance mode (start from the lowest range, that is from 200 ohms).

Now place the probes on two opposite ends of the material.

Now note down the Resistance value displayed on the LCD screen, if it becomes 1 then it infers that the values ​​you set are overflowed so now set the knob to next higher resistance range.

Repeat the above step still you get the stable value.

multimeter-measure-resistance

That's it, You are doing well now but before moving on try to measure the resistance so your tongue and some other objects.

Before you move on I want to put up a question, Can you use Resistance mode to test the continuity also?

[Tryit] Try to measure the resistance of a standard resistor and verify that tolerance levels are correct. [/ Tryit]

Experiment to measure Voltage

To do this experiment you need to have any working battery, here I am demonstrating with a 9V battery.

Connect the probes as I mentioned in previous experiments.

Set the knob to measure Voltage mode (start from the lowest voltage).

Place the Black probe to the negative end of the battery.

Place the Red probe in positive end of the battery.

You can see the voltage value on the LCD screen, If it becomes 1 then as I mentioned earlier the voltage of the battery is above the range you set in step 2.

Repeat the above step till you get the stable value.

multimeter-measure-voltage

Note that even if you are using a fresh battery the actual voltage you get may have deviated from the labelled voltage, this is due to various factors like battery internal resistance etc.

[Tryit] Now try to exchange the position of the probe, that connects black to the positive terminal and Red to the negative terminal.Did you observe anything ??? [/ Tryit]

Experiment to measure Current

In this experiment, I am going to measure the current delivered by the battery.

Connect the probes as I mentioned in previous experiments.

Set the knob to measure Current mode (start from the lowest).

Place the Black probe to the negative end of the battery.

Place the Red probe in positive end of the battery.

You can see the value of current in the LCD screen, If it becomes 1 then as I mentioned earlier the current delivered by the battery is above the range you set in step 2.

Repeat the above step till you get the stable value.

multimeter-measure-current

[Tryit] Now try to measure the AC voltage and Current that is supplied to your home. (Take parental guidance if you are a beginner) [/ tryit]

In the above experiment, we have measured the current delivered by the battery.Now if you want to measure very HIGH current, that is above 10A you have to make some adjustments.

Measure High Current (up to 10 A DC)

Connect the Black probe to COM port as we did earlier

Connect Red probe in the other port which we did not use for previous experiments. (10 A)

Set the knob to measure current.

Now connect the two probes in Livewire and Black wire in neutral pin of your AC port High DC current source you want to measure. (Current above 10A will blow up the fuse inside your multimeter)

The value will show up in LCD display.

If you forget to change the Red probe then the chances are very high to fuse your multimeter, so always do not forget to make the changes when you are measuring current above 10A.

[Tryit] Try to measure small current with the probe set to above-above 10 A.Did you get any value ??? [/ Tryit]

What else?

If you are not a good reader, following visuals can help you. (This video is not by me)

We have come to end of this long tutorial, Thanks a lot for showing much patience to read this article and I hope you liked it

Where can I buy Raspberry Pi in India ? [updated]

Being an Electronics Hobbyist in India, You need to wait few days or even months before you hands down to any new hardware. Raspberry Pi is no different from this trend, It took few months to spot Raspberry Pi in India.

So, Here I have listed few online hardware distributors through you can get Raspberry Pi in India. The list doesn’t follow any particular order, In fact, I advise you to research all before going with anyone.

RaspiModelB

CrazyPi

Bangalore-based online distributor fully dedicated to providing Raspberry Pi and Raspberry Pi accessories. Many users reported that they received within three days of the order and in good condition. Raspberry Pi Model B comes for Rs.3,125 and with casing Rs.3450 If you are a beginner get Raspberry Pi Model B Started kit for Rs.4,875.

CrazyPi is a great place to get all necessary accessories for Raspberry Pi such as  LED Display, Regulated Power Supply, Camera, Raspberry Pi Casings etc.

Digibay

Digibay is one of the pioneers of online embedded hardware distributors in India, You can get Raspberry Pi Model B 512 MB RAM for Rs.3199 and with the casing for Rs.3499 but I haven’t spotted any Raspberry Pi accessories.

Kits ‘n’ Spares

A well-known electronics hardware and Kits dealer in India, They made a contract with Element 14 to distribute Raspberry Pis in India.

Tenettech

It's also one of the earlier online stores to ship Raspberry Pi in India, Many users have reported the delay in shipping but their price is very much promising and worth checking.

RS Components India

A global leader in providing Electronics components and kits, The price seems to be very low (Rs.2950 for Raspberry Pi Type B 512 Mb) but they ship the product from UK, So you can add up Rs.1000 extra for custom duties.

If you are a cheapster then go with Tenettech and for a decent buy go with Kit ‘n’ Spares or Simple Labs.

Potential Labs

At potential labs you can buy Raspberry Pi Model B for Rs.3250 and Raspberry Pi Complete kit for Rs.4545. I consider it slightly overpriced but its a complete online store to buy Raspberry Pi accessories.

some other distributors

AnterBox – Model B Rs.3099

Sumeet instrument - Model B Rs.3250

I might have missed some other online stores, So add your suggestion as a comment below and help me to extend this list.

LED Fading Effect using Arduino – just like your Sleeping Mac

This is going to be really simple, It is a kind of Hello World Project for beginners. You might have observed LED which fades in and out when your Mac is sleeping.So we are going to make that cool effect using Arduino.

All you need is Arduino, LED, 220ohm resistor, A Breadboard and some wires.

Ok, analogLet's get started

Connect the Components as I mention in below Breadboard Diagram

Now Upload the following Program to Arduino

 const int LED = 9;

 int i = 0;

 void setup() {

 pinMode(LED, OUTPUT);

 }

 void loop(){

 for (i = 0; i < 255; i++) { analogWrite(LED, i); delay(10); } for (i = 255; i > 0; i--)

 {

 analogWrite(LED, i);

 delay(10);

 }

 }

The catch here is We need to take advantage of Analog output pins of Arduino to linearly Fade in and Fade out the LED,Arduino UNO has six analog pins -pin 3,5,6,9,10 and 11.

The syntax analogue output function

analogWrite(LED,128);

The above function assigns the value 128 to LED, The LED should be assigned with any one of the Analog output pin.

Analog output has a range of 0 to 255, which represents the voltage 0 to 5 volt respectively.Thats is if you give 0 as a output the LED will not be given any voltage and If it is 255(max value) the output will be 5 V.So you can calculate the resolution as 5/1256= 0.0195 V.

In the loop function I am iterating the for loop two times, One on forward direction by increasing the value of variable i and the other on backward by decreasing the value of i to its minimum value.The forward for loop will Increase the brightness linearly and the reverse for loop will decrease the brightness from maxim to minimum.

Now you can ask me why I am using delay function, It is because the change in output is instantaneous so It won’t appear Linearly if brightness is continuously changed, So I am delaying the next state by 10 milli seconds.

Isn’t that so simple ? but I would Like you to extend this project by adding some Other cool features.

Ok next time I will bang up with some complex Arduino Projects.
