First-order-consequence (11:30): It’s just a doorbell, so doesn’t worth my time. Second-order-consequence (12:30): It’s just a doorbell, costs a hundred or two in BDT. Better to purchase a replacement and still doesn’t worth my time. Third-order-consequence (15:30): Why not to give it a try by opening the skull of switch unit to investigate inside? Nothing… Continue reading Lazy stacking of my minds
Appetite for destruction
Forgot all of my mistakes and failures, my axe is coldHalf way through medieval, therefore I realizeMan, it’s the determination, rides the train to the Heaven or to the Hell Evolve with electronic junk, is the name of battleAnd it doesn’t feel so ashamed to crawl together as a snail It’s a mighty long way… Continue reading Appetite for destruction
The paradigm shift of my engineering practice
No, I didn’t forget the story! Back in elementary school, I was demonstrated the power of mirror as a catalyst to accelerate the boiling process of water. Far more than that, mirror is used to shape the odds in day-to-day life. Never imagine that this can be the story of evolution. I have to see… Continue reading The paradigm shift of my engineering practice
The Kernel of vector quantities
This unexpected pleasure occurred in designing a light dimmer during the ‘boot-meet’ of Snubberless Triac from STMicroelectronics (Phillips called it ‘Hi-Com’ or as generic 3-quadrant Triac). It was the zero-cross detection circuit that wondered me at the unexpected pleasure. My ‘yes-nodding’ head started to spin intrinsically when the zero-cross detection circuit met its left-brain, the mighty Arduino.… Continue reading The Kernel of vector quantities
The Commercial, the Free and the Wrapper
It has been six months since my curiosity soared towards Real-Time Operating System (RTOS). By this timeframe, I had the opportunity to work on two most popular RTOSes for the sole purpose of learning. One is which from open source domain, FreeRTOS and another is from the commercial domain, ThreadX. As the creative mind and… Continue reading The Commercial, the Free and the Wrapper
Hello (HardFault) World!
When capability failed and unaligned, exception handler takes over to dump the necessities as there always lies a desire to reframe the design before rebooting. The desire loaded into the boot memory when a soul failed in mathematics, and proudly said “It can’t be done!”. Hearing that another soul injected the malice, “If a soul… Continue reading Hello (HardFault) World!
