Electronic Door for Pets Circuit – Opens when Pet Nears the Door
In this post I have explained a simple electronic door circuit for pets which can be used as an electronic dog door for allowing only your specific pet dog to use the entrance, while keeping it locked for “strangers”. The idea was requested by Mr. Dave Monette. Circuit Objectives It’s been a while since we […]
How to Design a Solar Inverter Circuit
When a DC to AC inverter is operated through a solar panel, it is called a solar inverter. The solar panel power is either directly used for operating the inverter or it’s used for charging the inverter battery. In both the case the inverter works without depending on mains utility grid power. Designing a solar […]
How to Add a Dimmer Facility to a LED Bulb
In this article I have explained how to make an LED dimmer circuit for enabling a dimming facility to any mains operated LEDs bulb. How LED Bulbs Work We know that our ceiling fans and incandescent bulbs can be easily controlled using triac dimmer switches, and we are quite used to with dimmer switches in […]
How to Make a Zero Crossing Detector Circuit
Making a zero crossing detector circuit is actually very easy and it could be effectively applied for protecting sensitive electronic equipment against mains switch ON surges. A zero crossing detector circuit is mainly used for protecting electronic devices from switch ON surges by ensuring that during power switch ON the mains phase always “enters’ the […]
