Real Time Operating Systems
Real time operating system (commonly called as RTOS) is a software stack responsible for managing the workload and resources in embedded systems. The core of a microcontroller can execute only one task/ thread at a time, and given the capacity of modern days microcontroller, it would not be use of it’s full potential if they…
Toolchain of Arduino IDE for embedded systems
IDE (Integrated development environment) is a software development platform which provides all the necessary tools to developers for software development. A typical IDE consists of a source code editor, build system, compiler/ interpreter, debugger, uploader and serial monitor. Arduino IDE is a commonly used IDE among hobbyists, tinkerers and researchers[1]. The IDE is simple too…
Plastic – The Eco-Friendly Option
Seems Ironic, the topic of this fortnight’s discussion. Let us start by defining the term ‘Eco-Friendly’ – To begin with there is no specific definition, if you look it up online, “Any goods or services that have a low or negligible impact on the ecosystem or environment”. Most companies today use this term ambiguously (cannot…
Musical Haptics-I
Musical haptics is an emerging interdisciplinary field incorporating touch and proprioception in music scenarios from the perspectives of haptic engineering, human–computer interaction (HCI), applied psychology, musical acoustics, aesthetics, and music performance. According to [1], whenever an acoustic or electroacoustic musical instrument produces sound, that comes from its vibrating components (e.g., the reed and air column…
Hey Sssiri?
Voice assistant devices have become an integral part of our current technological environment: smartwatches, smartphones, smart-earphones, smart-homes and so much more lays ahead in the future. These devices allow users to make phone calls and send texts, do a quick web search, look up the weather, even control other smart devices (the coolest control I…
Square v/s Hexagonal Grid
Sometime back we were faced with the challenge of representing alphabets / characters in the least no. of cells (so-to-say). This was planned to be done in a swipe fashion i.e only one cell is “active” or ON at a time.We assumed a 3×3 matrix / array would be the best and optimum solution, as…
Sound as a construction material
Cast my first SuperCollider spell today. The code below spat out an .aiff file. This blogging platform may not allow me to embed that here in a straightforward manner so used VLC to convert it to an .mp3 file (which is what this 2 second clip is).
The touch of COVID-19, and haptics
22nd March 2020, India announced its first nationwide junta curfew, as a stint to reduce mass gatherings and implement social distancing, courtesy of COVID-19. Little was known that this one-day lockdown will be extended into a six-month long stint (with advisory for the current month: step out only when needed!). I saw the effect of…
How haptic Augmentation is improving the umwelt?
The way we perceive the world around us is dependent upon the senses inherited. Humans are blessed with five primary senses: Touch, olfactory sense, taste, hearing and vision. For all these primary senses, there is a dedicated portion in brain which works as processing unit and they have a receptor organ. Vision has most of…
