If you you need a super precise and steady beat for a song? A pierce oscillator is a musical instrument that can hit that exact note perfectly every time. It uses a special crystal, like a tuning fork to create a very stable electronic signal at just the right frequency. That is why it is […]
Simple Hartley Oscillator Circuit
A Hartley oscillator is like a gadget that makes very high pitched sounds electronically. These sounds are smooth and continuous, like a perfect whistle tone. The special thing about this gadget is how it creates these sounds. It uses a coil with a center tap like two coils taped together or a transformer along with […]
Simple Colpitts Oscillator Circuit
Think about a Simple Colpitts Oscillator Circuit like small kid on swing. Inductor and capacitor like swing are set as they make swing go back and forth. But swing can slow down. For that transistor come for help. It is like friend push a kid and keep swing move nice and steady. Same way Colpitts […]
Simple Automatic Soap Dispenser Circuit
Simple Automatic Soap Dispenser Circuit is like robot for soap. Inside it have a special plan like electric circuit with small parts. It has got sensor like small eyes, brain chip like microcontroller, and pump like tiny muscle. When sensor sees our hand its brain tell pump Give soap! and it gives the right amount. […]
