COLLEGE PARK, Md. – Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. The structure is called a nanopore: a tiny hole in a ceramic sheet that holds electrolyte to carry […]
Ever since I discovered nixies I wanted to make a clock with them, but all the designs I found were for 4 or more nixies, required a custom power supply and a complicated driving system. As the cheap guy I am, I didn’t want to buy lots of nixies or components to make such complicated
Infineon have announced two shields for the Arduino development environment. The RGB LED Lighting Shield (shown left) provides three independent output channels with a DC/DC LED driver stage to give flicker-free control of multicolor LEDs. It is fitted with an XMC1202 microcontroller using a Brightness Color Control Unit (BCCU) to help off-load time-critical events from
This video shows a simple circuit that can be used to control the position of an typical remote control (RC) style servo with an analog voltage. The PWM (pulse width modulated) control signal format for an RC servo is reviewed, followed by the presentation of a simple circuit that can be used to control the

The MAX5825PMB1 peripheral module provides the necessary hardware to interface the MAX5825 8-channel DAC to any system that utilizes Pmod™-compatible expansion ports configurable for I²C communication. The IC features eight independent 12-bit accurate internally buffered voltage-output DAC channels. The IC also features an internal reference that is selectable between 2.048V, 2.500V, and 4.096V (4.096V reference
Description This is my second encounter with LM3886. I was pleased of the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the chip with minor changes. I removed the time delay capacitor connected to MUTE pin,
We’ve already seen artificial skin capable of sensing touch and prosthetics that sense texture, but now a group of Korean scientists has come up with a stretchable electronic skin that “feels” in three dimensions. The artificial skin is made from arrays of microscopic domes that interlock and deform when pressed. It can detect the intensity,
Electronic skin can sense the direction in which it’s being touched Continue Reading
In this episode Shahriar compares the performance and features of the Siglent SDG5162 and Rigol DG4162 Arbitrary Waveform Generators. Siglent has recently opened a new North America office which would certainly help them bring their instruments to the US more quickly and provide better local customer and sale support. The Siglent SDG5000 teardown is presented.
MCUs are used as the main control element in just about every application imaginable. Their power and flexibility make them the go-to component at the heart of most designs. Since it is important to make sure that your design cannot be easily copied, reverse engineered or tampered with, modern MCUs now provide a few different
