How to Make an Incubator Timer Optimizer Circuit
A timer circuit design which could be used for turning the position of the eggs in an incubator between predetermined intervals of time was requested to me by one of the keen readers of this blog, Mr. Eugene. The requested circuit has been exclusively designed by me and published here, Circuit Specifications Let’s hear the […]
Simple Thermostat Circuit Using Transistors
The electronic thermostat explained here can be used to control the room temperature by appropriately switching (turning on and off) a heating device. By: R.K. Singh Operational details of electronic thermostat The circuit employs a thermistor NTC (negative temperature coefficient) as the sensor device. – As long as the ambient temperature stays higher than the […]
Making a “Helping Third Hand” for Aiding Soldering Jobs
In this post I have explained a step by step construction of a “helping third hand” unit for assisting PCB soldering jobs in order to make the job much hassle free. The gadget could be very handy especially for the new hobbyists. The project was constructed and submitted by Master Ss kopparthy. I have explained […]
Emergency Incubator Heater Circuit with Battery Charger
In this post I have explained a 12V power supply with battery charger circuit which can be implemented as an uninterruptible emergency heating system for incubator chambers. The idea was requested by Mr. Arya. Technical Specifications I’ve read all your good article, but can you help me to design an Linear PSU that provide 12 […]
Heater Controller Circuit Using Push-Buttons
Controlling a heavy electrical appliance with push buttons can be extremely convenient since it allows a solid state approach for operating the parameter both ways up and down by mere push of the relevant buttons. Here I have explained a heat controller circuit using a set of push buttons and PWMs. Using a Digital Push […]
