Build a Flashlight

I build this Flashlight using the 12 in 1 Microduino mPuzzle kit.

Learning Objective:

The battery gives power that moves through the wires of the device. All the pieces together are called a circuit & the energy moving through is called the current.

Parts needed:

Steps to build the Flashlight:

  1. Place two 3-point wire components on the board.

2. Place the bulb between the two 3-point wire components. Also put two 1-point wire components on the bottom most part of the 3-point wire component.

4. Add the graphic panel and battery. And turn the switch on. The bulb should light up as shown in picture below.

5. Congratulations! you just finished building a Flashlight !

Testing & Rebuilding your creations

R2D2 built with Little bits

Today I decided to tinker with the Star wars, Droid Inventor kit by Little Bits.

That’s the box it comes in

I downloaded the Droid inventor app on my phone from the Play store and started following the instructions.

After completing all the steps my droid would not move. I could see the connection between my app and the droid was made because it was making sounds it was supposed to make. I tinkered with it a little but could not figure out what was wrong. So I decided to take it apart and rebuild it.

This time I decided to check that the circuits work before putting the body on it. I turned the switch on and it started to move with the help of the toggle button on the app.

After checking that the circuits work I put the R2D2 shell .

This time everything worked as it was supposed to!

Here is the link to the post.

Two things that I learnt from this building experience is not to be afraid of rebuilding. The project might not be successful the first time, and that is okay!

And, the other is to keep checking for mistakes, before proceeding to the next step. That way you don’t have to take apart the whole thing.

What are you re-building today ?

Build a Remote Control LED

I build this Remote Control LED using the 12 in 1 Microduino mPuzzle kit. These magnetic, snap-together components can help teach basic circuitry concepts to kids.

Parts needed:

Steps to build the Remote control LED:

  1. Place the NPN, two 1-point wire components & one 3-point wire component on the board.

2. Place two 1-point wire components, one on top part of the NPN circuit and one on the bottom most part of the 3-point wire component.

3. Place the red LED, the touch button & the 2-point wire component as shown in figure below.

4. Add the graphic panel & battery. Also place one 2-point wire component on the right most corner as shown in figure below.

5. Turn the switch on & place your finger on the touch button & the LED light should turn on.

6. Congratulations! you build your Remote control LED.

Build a Lunar Eclipse

A Lunar eclipse occur when the moon passes directly behind the Earth and into it’s shadow.

I build this Lunar Eclipse simulator with the help of 7 in 1 mPie kit from MicroDuino.

Parts needed:

Steps to build the Lunar Eclipse simulator:

  1. Place & connect the power, dimmer & the Servo on the board. Then connect the power circuit with a power source( I connected it with my laptop).

2. Take the yellow graphic panel and connect it to the Servo arm with a rubber band.

3. Place the black graphic panel on the servo arm.

4. Place the above parts on to the servo. and attach it to the right side of the circuit. Also connect the wire to the blue circuit as shown below.

5. Turn the switch on. The yellow panel moves.

Congratulations you just built a Lunar eclipse Simulator!


ItsPhun Rangoli
ItsPhun Rangoli

My almost 4-year old is learning shapes at his pre-school. So I started looking for a hands-on activity to help him visualize it better. That’s when I came across Geometric Art by ItsPhun. If you remember my first blog was about Magformers, so I decided to give ItsPhun a try.

Since I was having a lot of fun with this new discovery, I decided to double the fun by making the same shapes out of my Magformer set. Below are the images of the same shapes made by Magformers(Left) & ItsPhun(Right).


The Magformers kit is for 3-years & older and the ItsPhun kit is targeted towards 5-years & older. So I decided to use the ItsPhun kit to make models to show it to my son, and he can use the Magformers kit which will be easier for him to make because of the magnetic abilities of the pieces.

What are you making today 🙂 ?

Build a Personal Fan

I build this Personal Fan using the 12 in 1 Microduino mPuzzle kit. These magnetic, snap-together components can help teach basic circuitry concepts to kids.

Parts needed:

Steps to build the Fan:

  1. Place two 2-point wire components on the board.

2. Place the motor between the two 2-point wire components.

3. Place the two 1-point wire components and put it on top of the blue part of the 2-point wire components.

4. Place the graphic panel on the motor.

5. Place the fan on top of the motor and the battery pack on the two 1-point wire components.

6. Your Fan is ready!

Build an Ambulance

I received this Microduino mPie 7 in 1 kit at work and got to bring it home to tinker with it before introducing it to my students. I decided to try the Build an Ambulance project first, since my son has a great affinity to police & ambulance vehicles & this would be a great way to spark his interest in Electronics! Also he gets a sneak peak of what mommy does at work!

The completed circuit board looks like below before I put the Ambulance cover on top of it.

Fun with Magformers

This is a Cuboctahedron. Ummm What ? Did you say that right? I didn’t! A cuboctahedron is a polyhedron with 8 triangular faces & 6 square faces. I made it with the 30 piece Magformers set. I was introduced to the Magformers set by a friend who gave this as a gift to my 3 year old son. As soon as he laid his hands on the box he was mesmerized by the bright colors and variety of shapes. As a parent I was super reluctant to open another box of toy for him, but boy I was wrong! The model booklet helps you to build different shapes. The pieces are magnetic so they stick to each other and is really fun for the child. Within a few days of playing with it my son knew the names of new shapes and how to build them. I was surprised at the amount of interest he developed in it. It is a good gift for a child or even adults who love to tinker.
