In this VS episode "GreatScott" will compare the hardware (CPU, RAM, GPU,....), the software and community aspects of the three most powerful single board computers from the fruit companies. Raspberry Pi 2 VS Orange Pi 2 VS BPi-M2 -...

In this article we will discuss about the various types of thyristors. Thyristors are 2 pin to 4 pin semiconductor devices that act like switches. For example a 2 pin thyristor only conducts when the voltage across its pins exceeds the breakdown voltage of the device. For a 3 pin...

If you´d like to use some of standard heatsink profiles, but you need for example an extra opening, we´ll supply it to you customized according to your needs. Perhaps everyone of us is familiar with a sentence mentioned in various catalogues, á la “upon request we can supply...
