Simple Electronic Fishing Lure Circuit
This article for Simple Electronic Fishing Lure Circuit shows how to make electric fishing lure. It uses small buzzer to make sound when fish come. Easy to make and also works very good. Be careful: fishing rules not same everywhere. Before using electric lure check in your country if it is allowed or not. What […]
Simple Beat Frequency Oscillator (BFO) Circuit
Simple BFO circuit is small electronic circuit which make signal sound when mix with other signal. This circuit help to hear weak radio signal like in old radio or metal detector. It is easy to build and uses one transistor part called a bipolar junction transistor (BJT). What is Beat Frequency Oscillator: BFO are used […]
