The rise in temperature level of a motor during its operation beyond a permissible limit is known as overheating. The causes of motor overheating are motor overloading, distortion in the supply voltage, impaired cooling capability, unbalanced supply voltages etc. Because of overheating, we can face the problems such as Electrical fire, Insulation failure, Decrease in […]

The circuit functionality is mostly obvious. There is polyswitch F1, a self-resetting fuse which protects the RPI from overcurrent condition. There is the Transient Voltage Suppressor (TVS) diode D5 which protects the RPI against static discharge and possibly overvoltage condition. However, the function of mosfet Q3 together with the matched PNP transistors U14 is not

After damaging the GPIO port on our raspberry pi while designing a new solar monitoring system we decided that it might be a good idea to build a buffer/level translator to protect the GPIO pins from over voltage and ESD spikes. The board would need to protect all of the data pins we normally use

The mouse is here. Gave up on looking on the web for programming help and ordered a book on the Raspberry Pi. While waiting for this to come thought I’d look at the GPIO bus. The GPIO bus allows the Raspberry Pi to control external electronics and handle various inputs. As well as 17 Input
