A team led by the Technical University of Munich (TUM) physicists Alexander Holleitner and Reinhard Kienberger has found success for the first time in generating ultrashort electric pulses on a chip. They made this possible by using asymmetric metal antennas only a few nanometers in dimension, then running the signals a few millimeters above the

If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in the megohm range, and can fall to hundreds of ohms
Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output Continue Reading
What’s up my friends, welcome back. What I want, is the aluminum block below to have let’s say, exactly 100 degrees. I’ll control the real temperature using a K type thermocouple. To read the data I’ll use the MAX66 75 breakout module and control the PID algorithm with and Arduino. Finally, to apply power we

Following up on Part 2, it’s time to talk about the output stage. This output stage is the brainchild of my friend Kostas, all I did was lay out the PCB. It is a fully discreet single-ended class-A output stage, outputting ~2.4V RMS. This is its schematic: This is the PCB: And this is the

Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG

Overview: This is the third generation of our succesful SODAQ ONE board. It is equipped with a solar charge controller and runs on a LiPo or a permanent battery. It has the Ublox Eva 8M GPS module which is not only miniature but with it’s assisted GPS feature it can get a fix within seconds. We’ve now
SODAQ ONE board – GPS + LoRa + Solar charger Continue Reading
The SFM4200 mass flow meter is a new star in the Sensirion range. Thanks to its high pressure resistance, it can be operated at pressures of up to 8 bar and measures flow rates up to 160 slm with a rapid signal processing time of 0.5 ms. It is particularly suitable for gas mixing in

MV is the ability of a computer to see using analog to digital conversion and digital signal processing. The key characteristics that make a machine vision module better are sensitivity and resolution. These systems allow machines to see a broader spectrum of wavelengths such as x-rays, infrared or UV light. Nowadays, it is mainly used
