New imaging breakthrough: KAIST-led researchers developed iDTT, using LED light to read 3D optical fingerprints in materials without lasers. Why LEDs matter: LED illumination removes noise and ...

Working under a pool means dealing with water pressure, unstable soil, and tight underground space. The structure had to be leveled and strengthened before allowing full water weight above it. Fatigue ...

When it comes to things that hackers build, PCBs are a sizeable portion of our creative output. It’s no wonder – PCB design is a powerful way to participate in the hardware world, making your ideas ...

A study of university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the ...

The two most important days in your life are the day you are born and the day you find out why. —Mark Twain Nick Craig is the president of the Authentic Leadership Institute. Scott A. Snook Scott ...

Custom printed circuit boards have become more and more accessible to the average hobbyist over the last decade. But one problem still remains: your circuits will take at least a couple days to ...

In the interests of transparency and to help readers form their own judgements of potential bias, Nature Portfolio journals' require authors to declare any competing financial and/or non-financial ...

After recently purchasing a quantity of SMD LEDs in various sizes and colours, I wanted a board that to which I could apply power via a USB cable and see them all lit up. This lets me quickly and ...

Abstract: High power light emitting diode (LED) has gained more and more importance over the last decade as a long-life general illumination source. To ensure a long-lasting lifetime of the LED module ...

Abstract: To improve the processing efficiency of the PCB drilling workshop, and to minimize the maximum completion time and the tardiness rate, this paper studies the random scheduling problem of a ...
