I have taken many courses over time, but very few were as interesting, engaging, and novel as IIT Bombay's III Course on NPTEL by Prof. B.K. Chakravarthy. So here is my review of this design and innovation course. Review of IIT Bombay's Design, Technology And Innovation Course It's a short, non-technical course that exposes you to various aspects of innovation…
While running yesterday, I noticed how this treadmill manufacturer used standard 7-segment displays with a decimal point to create a colon. The image shows the manufacturer rotating the 7-segment display and using its decimal point to form a colon for a clock. But why go through this effort? To understand that, let's discuss reducing BOM items and designing for manufacturing.…
I always have been a night owl, and I find myself motivated to dive into the deep end of the book at night. Lighting the whole room for reading was never an ideal choice. Using a desk lamp was not an option for me. I always found lamps so permanent and rigid that I was always looking for something better.…
In this post, we will finally look at the working Precision Current Source. We will assemble the device and calibrate it using a 34465A bench multimeter. Finally, I got this project almost to the finish line. I will tell you what is remaining. But for now, I am happy with how this project turned out. Precision Current Source Specification The…
Over-current protection is a type of circuit protection that stops your designs from releasing the magic smoke (getting damage). In some ways, most over-current protection circuits help with the over-voltage condition too. It's because as the voltage increases, the current draw increases too. What are our options for over-current protection? The simplest form of over-current protection is adding a current…
