The post presents a regulated 9V battery eliminator circuit which was built and investigated by Mr. Steven Chiverton, an avid reader of this blog and an experienced electronic hobbyist. I have explained more from him. 9 volt battery eliminator circuit tests: Circuits built 2x each circuit ive made a small modification to it buy adding […]
Newly Updated Circuit Projects:
Using Microwave Oven Parts to build a Soldering Iron Heat Controller
In this post I have explained how to scavenge discarded microwave oven parts for making a useful soldering iron heat controller circuit which can then be used for maintaining controlled heat over a connected soldering iron tip ensuring safe soldering operations, that may be quite crucial and handy if you are working with SMD parts. […]
Dual A/C Relay Changeover Circuit
In this post I have explained a simple relay changeover circuit which may be used for switching a couple of A/Cs or any similar load alternately in order to avoid misuse and save power. Technical Specifications Here is the situation: State: California. Facility: Church. The electric rate is greatly influenced by peak usage in any […]
High Wattage Brushless Motor Controller Circuit
This versatile Brushless (BLDC) motor controller IC is featured to control any desired high voltage, high current, hall effect sensor equipped 3-phase BLDC motor with extreme accuracy and safety. I have explained the details in depth. Using the IC MC33035 The “hero” of the circuit is the single chip controller MC33035 which is a high […]
Generate Electricity from Regenerative Braking System for Vehicles
Whenever brakes are applied in any vehicle, a lot of energy is wasted in the process of stopping the vehicle mass and again restoring the mass back to its original speed. The simple idea designed by me appears to be quite effective in solving this issue. I have explained more about this simple regenerative braking […]
Battery Health Checker Circuit for Testing Battery Condition and Backup
In this article I have explained a simple battery health checker circuit which uses ordinary components for enabling the user to get an instant reading of the battery efficiency or regarding its effective discharge rate. The idea was requested by Mr. Shrishail. Circuit Objectives and Requirements I need a circuit of a battery checker. It […]
