Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino ...

THE sensitivity of an ordinary hydrogen flame ionization detector to hydrocarbons has been found to be two to three times higher when the detector flame ‘whistles’ or ‘sings’. Further ...

The basis of operation of this detector is the increase in the electrical conductivity of a hydrogen flame which occurs when organic compounds are burned in the flame.
