The world’s tiniest temperature sensor is powered by radio waves

Researchers at TU/e have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor’s wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such sensors is an important development on route towards smart buildings, for instance. But the applications ...

Maker’s Rule-The Feature Packed PCB Multi-Tool

It has been a while since i posted my Tinker Rule which i made during college days. I received a few requests for the ready to etch pdf which helped me gauge if this seemed to be useful to people. The response was somewhat positive and so, i decided to put in some extra effort and make it handy, portable and manufacturable ! My initial scale was big and not handy, So, this one should be small and compact an ...
