Make Your Own H-Bridge Circuit for Inverters

“Thank you for stopping by this article on making a H-Bridge circuit for converting DC voltages to AC voltage. This simple yet effective setup is very useful in inverter applications where we need to convert high voltage DC to 50 …

Precision Thermocouple Amplifier (Thermocouple to Digital Converter with Linearization – SPI Interface)

“This precision thermocouple sensor module performs cold-junction compensation and digitizes the signal from any type of thermocouple. The output data is formatted in degrees Celsius. The converter resolves temperatures to 0.0078125°C, allows readings as high as +1800°C …

Single-ended Video/Digital input to differential output driver (High-Speed Differential Driver)

“The project described here is a low-cost solution to transmit a video or digital signal up to 300 Meters over a twisted pair cable. The project has been designed using the AD8131 chip which is a differential driver for the …

Smart Thermometer Using Esp-01F and Web Socket

“In one of the previous instructable, we saw how to make a simple thermometer with ATTINY 85 which can last for 140days with a single battery and it still works great after 40+ days with the same battery I showed …

Upload Codes Wirelessly in Arduino Board with HC05 Module

“This Uploader eliminates the need to remove the circuit board from the PCB or circuit board. A USB cable is not even required to upload the code. Simply wirelessly upload the code whenever you like using a laptop or a …

3 Phase AC input – DC Output – High Voltage DC Power Supply (2KW)

“Although this power supply design is specific to the Intelligent Power Modules (IPM) VFD drives, high voltage boost converters, high voltage battery chargers, etc, the concept and circuit design may be used for any power supply that requires a high …
