Week 1 at Cateina Technologies


I have joined as an intern in a company named Cateina technologies, which specializes in field of Blockchain technology.
On my first day, I was introduced to all members of the company.Along with me, my two friends have also joined as interns in this company. With a brief introduction of the company and its various products and ongoing projects, we were assigned tasks. We started our day by learning a online course on Bitcoin and other cryptocurrencies by Princeton University. I learnt about hash functions and their applications, consensus mechanism, proof of work methodology used by Bitcoin and other features of cryptocurrencies. This cleared all the doubts regarding bitcoin and its working principle - blockchain, which I had only come across in newspaper articles.
We were assigned an IOT(Internet Of Things) project. We had to come up with a prototype for Cold Storage Solutions.We were provided with an arduino kit and asked to come up with solution, within one week (which we did complete!).
Rest of the day we brainstormed over various methods to solve the problem and wrote down the specifications of the given problem statement. We came up with model which used RFID tag system. But later learnt that other checks like cost, reliability, size, etc have to be taken into consideration for a successful prototype.
We had HR activity on the second working day. I volunteered for the non-technical news. So that morning I read and explained recent events happening in fields of politics, sports, entertainment, health and fitness. After presenting each article of news, everyone would pour in their own opinions and we would have follow up group discussion. I really enjoyed the half an hour seesion we had.
On the second working day, we came up with alternative solutions, like temperature sensor, ardunio board sending data via bluetooth module or wifi sensor or 3G/leap sield.The problem of identification of containers in truck was resolved by assigning unique identification numbers to each container and truck by the arduino board, thus replacing the costly RFID system out of our prototype. For achieving long distance communication, to send the temperature and id numbers of containers, we decided to use wifi module in our prototype.
We had 'Fun Friday' group activity in morning, on my third working day. Every team had to come up with ideas for their own 'Mini Cateina' company and present its company's agenda, misson, long and short term goals on paper.We had to present our company's goal and vision using newspaper and magazine cutouts.Each team would decide the CEO and respective members of company. That was also enjoyable.
On our third working day, we were completing our project and writing the code for the arduino board. We learnt how to code using Aduino IDE. We learnt how to build circuits. We simulated our temperature sensor by entering temperature values and wifi module was simulated using a LED alert. If temperature value would be out of range then an alert would be raised, otherwise not. At the end of the day, we presented it to our manager and it was accepted.
