Dear friends,

Nearly Six and half years back I had moved to a village or rather a small town called Ujire after quitting my job at GE to work on Solar Photovoltaics technologies for Rural Electrification in a company called Selco. I was working as a R & D engineer. My work was to develop solar products suitable for the rural community. I was also given an additional responsibility to guide young engineering students as part of an internship program in Selco. In this process, I had met a young boy by name Suraj Hebbar, who became my intern. I was thrilled to know that he had developed robots using micro-controllers and other electronic components in that small town, where there is absolutely no access to electronic components. I don’t know how much I guided him back then but today I’m very proud to see him as a very successful hardware engineer, who gladly agree to give the guest lecture on Electronics Hardware Circuit Design to my IIoT class at IISc.

Before Suraj’s class, we had a presentation by one of the participants of the class on concept design of Solar Powered Street light monitoring system — which wasn’t presented in the previous week’s class because of time constraint. Suraj started the presentation with his earliest experiments in electronics. He had got the pictures of some of the printed circuit boards he had prepared during his college days (2011). He also presented some of the circuit boards he did as part of Systems Lab at IISc. The presentation became very interesting when he started the slide “ Do you know the rules of Product Design?” As part of rules, he had four slides: 1. Get the fundamentals right 2. Set the specification 3. Budgeting: Costs, Performance, Power 4. Anticipate (Think ahead). I could see his journey from a passionate hobby electronics geek in college to lead hardware designer for Pathshod Healthcare as he went through his presentation. He also shared interesting design tips for Digital circuits, Analog Circuits and Mixed Design Circuits. He also took some cases to showcase the dilemma a hardware design engineer would go through during product design phase.

Suraj’s presentation lasted for 40 minutes after that we had a very long Question and Answer session. Some of the participants, who are working on the electronics circuits for the problem statements that we have defined, took a greater interest in getting their doubts clarified in circuit designs, choice of microcontroller and micro-processors, packaging etc. Since I also come from electronics circuits background, Suraj and I had an open discussion in front of the participants about topics that were not particularly addressed by me or previous guest speakers. During this discussion, we could derive interesting techno-commercial aspects involved in product design with a focus on electronics hardware. By the end of the class, I was pretty exhausted with all the questions that I had prepared for the class and I could sense Suraj was very happy to have interacted with the class while presenting his journey in circuit design.

Having Suraj in my class as a guest speaker will remain as a great feeling for time to come. Thanks again for going through the affairs of the 9th week of this 14 weeks course on IIoT. I’m also happy to share the media coverage of this course for your reference: http://goodworkscowork.com/industrial-iot-entrepreneurs-created-marketable-products-within-14-weeks/
