Dual sharing RTC

Necessity I have an old window AC at my lab, situated at the terrace. The AC needs to be run intermittently more so often when I’m out of the station and the lab PC needs to be cooled down during the intense noon time when the temperature shoots 35+ degree centigrade irrespective of summer or winter. Of course, the thermostat works! But it needs to be changed continuously else it will keep on running for pr ...

Latching Relay Module

In electronics, a device is said to be a latching device if it maintains any particular fixed state even after removal of the input signal. The same also applies for electronic/electromechanical relays. Basically the electromechanical relays that are used today are of two types: 1. Non-Latching Relay : These relays are most widely used where energy consumption is basically not an issue.This type relay(s) co ...

The 10 Trillion FPS Camera Captures Light In Slow Motion

Light moving in vacuum is the fastest thing in the universe. Scientists have tried many times before to catch it on the move with some success. This time a new equipment built by Caltech scientists pulls down a mind-blowing 10 trillion frames per second, meaning it can capture light as it travels along, and also they are working to make it a hundred times faster. Understanding how light moves through a medi ...

FLIR Boson Camera Frame Grabber using FPGA

Description A small PCB designed to attach to the backside of the FLIR Boson Thermal Camera. The PCB facilitates configuration of the camera along with capturing data to an SD card. This project is mostly an exercise in project-based learning. Instead of researching and reading about FPGAs, I want to create a project actually using them. Of course, this means that I'll likely get things wrong, but that's ju ...
