For many PCB enthusiasts, seeing their DIY PCBs in action is more than sufficient to give them high levels of satisfaction and fulfillment. But hobbyists may be shooting themselves in the foot and be better served to go that extra mile - gaining an edge in their applications by optimizing their design with the use of professional PCB design software. For this article, we referenced popular software apps Eagle, Fritzing and xcircuit.
In nowadays technology advance very fast, so more devices support high capacity micro sd cards. Because of very fast advancing of technology prices of high capacity micro sd cards is going down. Because of less knowledge about storage devices and technology of some people, some other people sell Fake/Counterfeit micro sd, usb sticks and many other storage devices.
In many case this electronic storage devices has a real low capacity that expected. But if you plug your storage media in any device like PC, phone, tablet you can be misled because you’ll see a fake capacity.
The AD8494 , AD8495 ,AD8496, AD8497 are easy to use amplifiers for J and K type thermocouples , that convert a small voltage generated by a thermocouple junction into a signal that can easily be read by an analog-to-digital converter (ADC) or microcontroller. The gain from the thermocouple to the amplifier output is approximately 5 mV/°C.
