The battery charger circuit below is very simple to build requiring only a handful of cheap parts and an extra winding on your power tranny (or a separate tranny). Since the charger described is not active during sound reproduction, I have made no criteria on parts quality, so el-cheapo was the way to go. There [...]

This lie detector circuit can be built in a few minutes, but can be incredibly useful when you want to know if someone is really telling you the truth. It is not as sophisticated as the ones the professionals use, but it works. It works by measuring skin resistance, which goes down when you lie. [...]
Description: The idea for this project may have come to me in a flash of inspiration, and its a very simple way to check if a fuse has blown without removing it from its holder. Notes The simplicity of this circuit uses just two components, but with just one resistor and an LED this circuit [...]
I saw many car product in thermo sensor ,so i would like to show you the LCD thermo sensor which can modify for your car. LCD car thermo circuit When the thermometer is the IC thermo sensor (S8100) or diode (1S1588) is used as thermal sensors. When using the IC thermo sensor, the thermometry to [...]
