#03: THE MISSING DOLLAR

Three people check into a hotel, pay $30 for a room and immediately get into the room to get refreshed.
But the cost of the room is $25. Thus a bellboy is sent to their room to return the remainder of $5. 
On the way to the room, the bellboy reasons that $5 would be difficult to share among three people. So he pockets $2 and gives $1 to each person.
Now each person had paid $10 and got back $1.

The bellboy has $2, totalling $29.
Where is the missing $1

#02: A THOUSAND BOTTLES OF WINE

You have 1,000 bottles of wine, and exactly one bottle is poisoned. You need to find the poisoned wine before your party starts in an hour. You have 10 rats to test on to find out which bottle is deadly. The poison takes effect after an hour of consumption, so you only have one chance to run your rat poison experiment, meaning you can’t feed some rats wine and wait an hour before feeding them more wine. Assume each rat can drink as much wine as you feed it. How do you find the poisoned wine?

Christmas style Paper Circuits!

We had a paper circuits workshop in December, and of course, we went with the Christmas theme! The group of bright young creative students all made christmas ornaments that light up!  They picked their design, chose their colors, and made the ornament. Then they learnt how light bulbs and switches work, and they applied their new knowledge to make fantastic, take-home creations. Here are a few in pictures.

Creative process is messy, and fun!

Lots of fairies and angels!

And here’s a blue nosed reindeer, because, why not!

Isn’t this snowman cute?

Maker Faire Bengaluru 2017

Tinkerama exhibited at Maker faire 2017! It was as exciting as we thought it would be!

This was Bengaluru’s very first maker faire. It was held at Bangalore Palace, on Nov 17th and 18th. We turned up early on 17th and set up our booth.

 

Come 9am, people started pouring in. We had plenty of demos to show off.

The POV was a crowd puller! Here’s our POV in action, showing different messages on the fly.

Here’s ardoodler, making the most amazing doodles! Kids loved the doodling. We made buses and cars, trees and leaves, names and signatures. It was a lot of fun!

 

The magic lamps dazzled, as did the theremin. We also did a workshop on the Arduino theremin, and people loved it!

 

We loved connecting with the enthusiastic, fun crowd, and made lots of friends in the maker community! We hope to be at more such fairs in the future!

About Me

I’m an engineer by day and avid tinkerer in my free time. I love making and building things, and tinkering with electronics. I also love to teach. Tinkerama is an effort to combine the two, and encourage a whole generation of innovators and makers! I have workshops designed specially to teach learning through making and tinkering, with materials, tools and electronics. This approach to teaching is geared to instill creative confidence in students, enabling them to innovate fearlessly.

Experience

I completed my Masters in Electronics Design from IISc, Bangalore, and have worked as a firmware engineer in the semiconductor fied.
In my free time, I build things with Arduinos and Raspberry Pis.
I had the wonderful opportunity to volunteer at The Tech Museum, San Jose, during my stint in the Silicon Valley. While interacting with kids at the museum, I realized the power of learning by making.
I also collaborated with like minded folks with Workshop Weekend and Codechix, conducting workshops that teach electronics through making.

I live in Bangalore, with my wonderful husband and lovely daughter.
