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 […]
Greywater Purifier Desalination System
In this post I have explained a simple grey water purifier, desalination design arrangement which can be used for recycling greywater into pure usable distilled water completely free of cost through solar heat concentration. The idea was requested by Mr. Luis Gomes Machado Circuit Objectives and Requirements I wrote to you on a forum last […]
Customized Water Flow Controller with Timer Circuit
In this article I have explained a customized water flow controller circuit with timer.he idea was requested by Mr. Daljeet Singh Sokhey. Technical Specifications Right now I am working on a different project and would like your help. There are 2 inputs and both must remain high for a period of 30 seconds for the […]
