Wvdv2002 shared his digitally controlled power supply with us in the forums. It’s capable of driving 0-18V while having a current controlled output of 0-3A. The brains of the design is the PIC18f46j50 which controls a switch mode regulator’s voltage and current output through the MCP4822 two channel I2C DAC. Via the forum.

Phase Lock Loops 101 with Bil Herd
Robert let us know about another video tutorial on Phase Lock Loops in the comments of our previous post. PLLs generate an output signal that is phase-synchronized to an input signal. They are widely used in telecommunication, radio, and computer systems. One place we commonly find PLLs is the frequency multiplier circuit inside microcontrollers. The […]
USB Analog/digital logger
Arhi started started working on a USB/UART analog and digital logger: It’s a simple USB logger that can log 12 analog and 3 digital channels + data from MAX6675 (thermocouple driver). It sends the data via usb or uart. We think this is a very useful device that has a place on every bench top. […]
