Simple Static Electricity Detector Circuit
Simple Static Electricity Detector Circuit is like alarm for electricity when gathers on things like clothes and this happen when we rub things together. Also, this kind of electricity can break small electronics, so detector is useful near them; also detector have special sensor which feels electric change in air. Maybe its wire stick out […]
Simple TV Remote Tester Circuit
Simple TV Remote Tester Circuit is small tool like a doctor for ones remote, as it uses one infrared sensor like eye for light which we cannot see and to check if remote give signal when one presses the button. If signal arrives small light turns ON or buzzer make beep sound which means remote […]
Simple Heat Sensor Circuit using a Single Transistor
To begin with, this Simple Heat Sensor Circuit using a Single Transistor and one special resistor like thermometer. When it get hot this resistor changes to how it work because of which the transistor sees this change; also the transistor work like a door and if temperature changes it opens or closes for electric. So […]
Simple DC Electronic Fuse Circuit
Is anyone sick of the fuse blowing? then this Simple DC Electronic Fuse Circuit can be helpful! DC electronic fuse circuit is like small hero for ones electronics, as it protects from big current going crazy. Old fuse? we break it then one may need new one, but this one? it uses smart components always […]
Simple Audio Frequency Signal Generator Circuit
Have anyone ever thought that how electronic makes sound? Audio frequency signal generator it like small sound maker, it make electric signal what ear can hear from low boom (20Hz) to very high squeaky (20kHz). Also, this Simple Audio Frequency Signal Generator Circuit very helpful for many thing: Circuit Working: Parts List: Components Quantity Resistors […]
