Digital Voltmeter Circuit Using IC L7107
In this post I have explained a very simple digital panel type voltmeter circuit using a single IC L7107 and a few other ordinary components. The circuit is able to measure voltages right up to 2000 AC/DC V. About the IC L7107 Making this simple digital panel voltmeter circuit is particularly easy due to the availability […]
15V 10 Amp Voltage Regulator Circuit Using IC LM196
In the following post I have explained a linear voltage regulator power supply circuit using the IC LM196 which is capable of handling up to 10 amps of current and is able to provide a variable voltage right from 1.25V to 15V DC. About the IC LM196 or LM396 The IC LM 196 is single […]
Temperature Controller Circuit for Reptile Racks
The following article discusses a temperature controller circuit which can be used for controlling the temperature inside reptile racks. The idea was requested by Mr. Tom. Technical Specifications I’m looking to make a circuit to use to heat my reptile rack, I really like your incubator circuit, but do not have the electronics expertise to change it to suit […]
12V 5 Amp Fixed Voltage Regulator IC 78H12A Datasheet
The post explains the technical specifications, datasheet, and application notes of the IC 78H12A which is a voltage regulator IC capable of providing a fixed regulated 12V output at maximum 5 amp current. 5 Amp Regulator Specifications We are familiar with the popular 78XX ICs such as the 7812 IC which can produce 12V fixed voltage at […]
Pellet Burner Controller Circuit
In this post I have explained a programmable sequential timer with controller circuit which may be used for automatically controlling a homemade pellet burner/boiler system. The circuit was requested by Mr. Vasilis. Technical Specifications I have used your circuit on my homemade pellet burner that uses a 12V Ac motor for the feeder screw running […]
