Recently, Silicon Labs announced a new USB controller called CP2102N which is part of the USBXpress™ bridge devices family. CP2102N have a battery charger detect functionality to notify an external battery charger with the amount of current available from the USB interface (100 mA, 500 mA or 1.5A). CP2102N also have up to 7 GPIOs […]
IRis – An Infrared Sensor using Photodiode amplification Circuit
https://www.electronics-lab.com/iris-infrared-sensor-using-photodiode-amplification-circuit/
[devttys0] designed a sensitive IR detector for capturing weak infrared signals. He shared in detail how he designed the circuit, beginning from the basic components, walking through solving the problems and finally ended up with a complete working circuit. Craig Heffner/[devttys0] built this circuit for a friend’s Defcon talk, Blinded by the Light, the talk […]

DIY ECG with 1 op-amp
https://www.electronics-lab.com/diy-ecg-with-1-op-amp/
A DIY ECG made from single op-amp (LM741) and 5 resistors by Scott Harden: I made surprisingly good ECG from a single op-amp and 5 resistors! An ECG (electrocardiograph, sometimes called EKG) is a graph of the electrical potential your heart produces as it beats. Seven years ago I posted DIY ECG Machine on the […]
PCB layout tips for thermal vias
https://www.electronics-lab.com/pcb-layout-tips-thermal-vias/
Paul Rako @ edn.com discuss about thermal PCB layout tips. Texas Instruments’ WEBENCH is a neat program, especially because it has Mentor Graphic’s FloTherm built in to help you see the hot spots in switching regulators. This is what taught me that a modern buck regulator will have more heat coming out of the catch […]
Space Invaders FPGA Game
https://www.electronics-lab.com/space-invaders-fpga-game/
Patsiatzis Nikos and Katsaros Nikos build the space invaders game using a ZedBoard FPGA. The project’s code is available on github. This two person project was completed through the course of Embedded Systems at the University of Thessaly, Department of Computer Engineering. In the context of this game we implemented the classic space invaders game using a zedboard fpga. […]
An isolated analog input for Arduino
https://www.electronics-lab.com/isolated-analog-input-arduino/
Giovanni Carrera designed a circuit that accepts input voltage from about 20mV to 5V or a current of 4 to 20 mA and converts it to a isolated frequency signal. A voltage to frequency converter can realize an opto-isolated analog input for Arduino or other microcontroller systems. This circuit is particularly suitable for industrial control […]
