ECE students of Chitkara University H.P. turn entrepreneurs @Chitkara Mandi

Chitkara Business School organizes Chitkara Mandi every year during Oct-Nov at Paras Downtown Zirakpur where MBA students are evaluated for their Sales & Marketing Skills. From last couple of years ECE department of Chitkara University Himachal Pradesh is also taking part in the event where ECE students demonstrate, promote and sell their low cost, innovative electronic products designed by them in university labs.


The activity provides a very good overall exposure to our ECE students. They go back to their electronics basics and come up with a innovative ideas that can be realized in a form of products, they learn the basics of electronic product design, they learn different ways and means to cut down the cost of their product to keep the selling price low, they learn art of marketing, promotion & branding and lastly they learn team work, tackling unappreciated challenges and working under tight deadlines to deliver a final products. After all the hard work they taste success when they sell their products to customers at Chitkara Mandi and generate revenues for themselves. The whole exercise gives our students a feeling of being entrepreneurs and motivates them in think in this direction.

This year Chitkara Mandi was held during November 6-7 and around 20 ECE students participated with 4 electronic products all designed, developed and manufactured in university labs. Schematic and PCB layout design of electronic circuits was carried out using Proteus PCB designing tool. PCBs were manufactured in-house using copper clad boards etched using Ferric Chloride followed by assembly of components. Once the electronics was ready, the circuits were beautifully packaged inside aesthetically designed casings by the students.

A brief overview of the products is as follows:-

  • MBOX – MBox is a portable music box which contains an audio amplifier circuit and an inbuilt speaker. You may connect your mobile phone to it using an auxiliary cable and play music through the MBox. It is powered by microUSB (mobile phone with OTG can also power it) and it also has a provision to connect two external speakers. Students made 6 units of MBOX, with a selling price of INR750 each.


  • 3D Floral Lamp – This product was designed keeping festival in mind. It has 555 timer based LED fader circuit. Timer is used in Astable Mode and a capacitor is used whose charging and discharging is controlled to give fading effect. Circuit is powered by 9V dc battery. Ultra low power LEDs are used to keep the power consumption to minimum. Colorful reflectors are used to spread LED light to give good lighting effect and outer layer has flower decoration cut to give 3D effect. 12 units were made each with a selling price of INR350.


  • Automatic Lamp – It was another product for the festival, 10 units were made with a selling price of INR350 each. It is a decorative lamp shade that automatically turns-on during evening and turns off during morning. In this product a LDR (light dependent resistor) is used that sense the ambient light and gives a trigger to LED circuit to ON or OFF depending upon the ambient light. It is powered with 2 AA alkaline batteries


  • LED Cube – This product is based on microcontroller. It uses ATMEGA328 8-bit microcontroller from ATMEL which is programmed to give 18 different set of patterns in 4X4X4 LED cube matrix. Anodes of LEDs are connected row wise and Cathodes are connected column wise. Anodes are then connected to 4 GPIO pins of microcontroller and Cathodes are connected to 16 GPIO pins (through multiplexing technique). The assembly is packaged inside acrylic casing that reflects light and also gives strength to the product. Two units of this product were made with a selling price of INR1700 each.
  • Total revenue generated by the students during Chitkara Mandi from selling these products was INR13150

    Names of the students who were involved in these projects are Nilesh Khanna & Aniket Bharadwaj (MBOX), Abhijit Dey, Sajal Puri, Ranjan Mukherjee, Birinder Singh, Nishesh Mehta (3D Floral Lamp), Himanshu Arora, Shubham Garg, Ridhi Jain, Saurabh Awasthi (Automatic Lamp), Jaskunwar Singh & Jaskanwal Singh (LED Cube)

    Thanks are due to Dr. Rajnish Sharma, Dean Academics for providing this opportunity.
