How We All Can Help Fight Covid-19 By 3d Printing Masks


In light of the COVID-19 pandemic, surgical and N95 masks
are becoming increasingly harder to find. The maker community,
might provide a Plan C as stated in this article. One design has
gotten my attention for its simplicity and low cost. This design
has a 3d printed brace that is the frame for the mask. A
filtering material (2-4 ply cotton dish towel) can be put on the
face and the brace can be put over to act as a sufficient mask.
According to a Cambridge study done in 2013 shown in this blog,
2 ply dish towel is 97% effective at stopping viruses the size
of the novel coronavirus. This is as effective as a surgical
mask. The dish towel can be washed after every use, and anyone with a 3d printer can help make these masks. It takes only 16 minutes per mask, and due to the size of the maker community, we can mass produce these masks at almost any scale.

O Watch @ Maker Faire Bay Area 2018

O Watch is a project that I have been working on for a while now. It is a programmable smartwatch that I created in partnership with TinyCircuits, a company that makes small circuits. I am hoping to exhibit my latest O Watch at Maker Faire Bay Area 2018.



This year O Watch will have more sensors and bluetooth connectivity compacted into a small case, as well as new programs that will be more usable.

I am excited about going to Maker Faire Bay Area 2018. I hope to inspire other kids like myself to start designing, 3D printing and programming. See you there!


Maker Faire Bay Area 2016, best one yet!

Every kid should make something and exhibit at Maker Faire!

Maker Faire Bay Area is one of the few events where kids of all ages get to show off their creations to a large audience and get a chance to meet makers, inventors and leaders from all over the globe. And this year it was bigger and better!

For Omkar (a huge fan of Mythbusters), the absolute highlight of the event was meeting Adam Savage!

The biggest shout out for Omkar’s project came from none other than Massimo Banzi, the co-founder of Arduino, who talked about Omkar and O Watch in his annual State of Arduino address (at 15:30 in this video)!


The best part of Maker Faire is meeting old maker friends and making new ones, not to mention experiencing all the cool exhibits and activities.


Some of the kid makers we came across (there were many others):

Mark you calendars for the next Maker Faire or similar event near you and encourage+help your child make and exhibit something. It’s just an awesome experience for kids! Nothing quite like Maker Faire Bay Area.

And one more thing…. Omkar got featured in the local newspaper! 🙂 🙂

Kid maker to entrepreneur, celebrating the spirit of Maker Faire

It was back in 2013 Omkar made his very first Arduino project at the age of 6 having attended couple of Maker Faires by then. At the 2014 Maker Faire, he got to meet Quin and several other kid makers inspiring him to dream of starting a business. But he had to come up with a product idea first. 🙂 After toying with several ideas, he decided on making a kid’s smartwatch. His first effort was received with much encouragement from the maker community including Atmel and Adafruit.

Omkar exhibited a prototype at MFBA 2015 and got validation from other kids and parents who showed keen interest. All the words of encouragement from makers and well wishers including the folks from Particle, Pebble and Atmel motivated him to go ahead with the project. This really speaks to the spirit of the Maker Faire community that is super supportive of all makers, especially kids.

There Omkar also met the CEO of TinyCircuits who kindly accepted our request to partner and supply the required electronics. Further, Kickstarter made it possible for him to bring O Watch to market with the kind support of awesome backers from across the globe.

Omkar’s vision for O Watch is to inspire kids to get started with design, 3D printing, crafting and coding while making a fully functional product they can use daily. And he wishes to meet more makers and partners at MFBA16 to make O Watch even better and accessible for kids.

If you are in Bay Area, don’t miss Maker Faire! It is the event where kids will get exposure to all types of making and meet budding entrepreneurs to experience first hand the basics of kickstarting a business.

Please stop by the O Watch exhibit in Zone 2 for a chance to win an O Watch! For those who are unable to make it to MF, we’ve a 10% discount to celebrate Maker Week using the promo code 10OFFMF16 via the O Watch store.

O Watch successfully funded on Kickstarter!

O Watch Kickstarter successfully funded! 

O Watch is an Arduino based smartwatch kit for kids to get started with hands-on programming and 3D design. It comes with a complete set of components and easy-to-use instructions to create your own smartwatch. You can customize it by creating 3D printed watch cases and colorful straps using various band making techniques like paracording.

The O Watch kit comes in two variants:

Base watch kit: Arduino Zero based programmer board with integrated color OLED screen, LiPo battery, 3D printed watch-case and para-cord kit.

Smartwatch kit: Base watch kit plus sensor board with integrated 3 axis compass, temp, barometric pressure and humidity sensors.

O Watch Cases 3D Printing: O Watch cases can be 3D printed at home or via one of the several 3D printing services or maker-spaces convenient to your location. We are actively working on creating a 3D printing partner ecosystem for kids to easily customize and 3D print O Watch cases in a variety of colors and materials.

O Watch Kickstarter is successfully funded! Thank you to all the backers and supporters!

O Watch Interest List: If you missed the Kickstarter and would like an O Watch, please visit to order one for yourself.

Simple way to integrate Twitter to your projects using Photon and IFTTT

The folks at Particle (erstwhile Spark) are awesome – they make great IoT products and are really super nice people. They gifted Omkar a Photon at the MakerFaire. His summer break just started and this was his priority #1.

Omkar wanted a way to know when someone mentions or follows @IoT4Kids. Particle makes this incredibly easy to do with just a few lines of code. You essentially can make any action happen (light up or move something and/or make some noise) based on Twitter activity using their Arduino compatible WiFi integrated micro-controller and their integration with IFTTT.

This simple example lights up an LED.

BTW, the display box is 3D printed using Printrbot Simple which is another awesome product for kids to get started with 3D printing.

This is all made so easy with the Particle Spark.Function() that is triggered ‘automagically’ 🙂 from IFTTT. All you need is the code below and create a recipe with Twitter trigger and Particle action.

int ledpin = D7;
void setup()
// register the cloud function
Spark.function("tweet", twittermessage);
pinMode(ledpin, OUTPUT);


void loop()
digitalWrite(ledpin, LOW);

// this function automagically gets called upon a tweet mention
int twittermessage(String ignore)
digitalWrite(ledpin, HIGH);

Here is a more fun example of this by Brian Sherwin. He also has an example of making this with your own node.js application to make the action trigger immediately instead of the 15 min cycle on IFTTT.

So folks, if you liked this please follow or mention @IoT4Kids and light up Omkar’s day. :).

Truly the greatest show on earth!

That’s Omkar’s statement after exhibiting his O Watch as a maker for the first time at Maker Faire 2015 Bay Area. Thanks to the organizers, volunteers and all the amazing makers, attendees and exhibitors for the encouragement and support.

O Watch at Maker Faire!

Happy Pi Day! An Arduino Pi Program on TinyScreen

Archimedes of Syracuse (287 BC – 212 BC)) was one of the first to device an algorithm to calculate the value of Pi.

On Pi day we decided to make a simple program to calculate Pi on an Arduino compatible TinyScreen using the Leibnitz formula for Pi.

The Leibniz formula for Pi is: Leibniz Pi

Here is the video of the program:

Here is program code:

//Add TinyScreen Libraries
#include <TinyScreen.h>;
#include <SPI.h>;
#include <Wire.h>;

TinyScreen display = TinyScreen(0); //Initialize TinyScreen

// Initialize the variables
float Pi=0;
float  n=1.0;
unsigned long i=0L;

void setup(void)

void loop()
 // the recurring calculations of formula
 n=n+2.0; // Increment the denominator by 2

 // Print the values
 display.setCursor(12, 14);
 display.print("Happy Pi Day");

 i=i+1; // Increment the counter
