Simple metal detector.

Hi everyoneThis time I m gonna show you how a simple metal detector works. I will be using the oscillator circuit and the coil transformer in the previous post, which I have modified it into a simple metal detector. The circuit is shown below:The LED is made an indicator for the detector. The coil transformer is the detection coil. Object is put into the centre of the coil for d.......

How to build Flashing-LED Battery-Status Indicator Circuit - circuit diagram

A Battery-status Indicator circuit can be useful, mainly to monitor portable Test-gear instruments and similar devices. LED D1 flashes to attire the user's attention, signaling that the circuit is running, so it will not be left on by mistake. The circuit generates about two LED flashes per second, but the mean current drawing will be about 200µA. Transistors Q1 and Q2 are wired as an uncommon complementary astable multivibrator: both are off 99% of the time, saturating only when the LED illumi.......
