CIRCUIT IDEA: Getting To Know IC 555 Through Experiments (Part 2)
The first six circuits to learn the theory and digital logic behind twelve simple experiments that can be performed using IC 555 were published in December 2022 issue. Here are the remaining six circuits
INTERVIEW: “Non-Free Programs Are A Threat To Everyone’s Freedom” — Richard Matthew Stallman
Richard Matthew Stallman (aka RMS) can be best described as a genius or a maverick. He graduated from Harvard in physics while working at the Artificial Intelligence Lab in Massachusetts Institute of Technology. In 1984, he started developing the GNU operating system, then in 1985 he founded the Free Software Foundation and invented the concept of copyleft—a legal mechanism to protect the modification and redistribution rights of free software. How have things progressed? How happy is he with the current state of affairs? Given the increased awareness and use of free software, we had (wrongly) assumed that he would be happy with the progress. He not only reiterated the weakness in defence of freedom but also outlined the threat humanity faces when “progress” (in the purely practical sense) is promoted at the neglect of freedom. Let’s see what he has to say
DESIGN: Developing Lovable Products To Win Over Competition
This article and the forthcoming in the series will explain what makes a product lovable and how to consistently create such products for brand building to win over any competition in the market
CIRCUIT IDEA: Remote Controlled Corona Protection Bell
The World Health Organization (WHO) recommends that everyone should rub their hands with soap for at least 20 seconds before washing with water to prevent transmission of the novel Corona virus, which is again on rise, in addition to social distancing. The 20-second period can be checked with wristwatches and the stopwatches on mobile phones, but these are not convenient to use while washing hands. This proposed circuit rings a buzzer for 20 seconds and switches on an LED for audio as well as visual indication
PROJECT: Thermal Management System For Electric Vehicles
Recently some electric bikes caught fire due to failure of battery management system because of poor battery design. Unfortunately, proper thermal management is not there in most electric vehicles at present. So, here is a project to monitor the battery temperature and smoke detection to alert the EV user and stop the EV well in time to avoid further damage

PROJECT: Nuclear Bomb And Radiation Detection Device
Nuclear radiation is one of the most dangerous killers for the living. The atomic radiation needs to be detected at an early stage, otherwise it can be devastating within its area of influence. The radiation kills not only humans, it also destroys all natural habitat. It is important to avoid harm and mass destruction that can be caused by nuclear weapons and reactors nearby
