The researchers at Stanford University have discovered two ultrathin semiconductors – hafnium diselenide and zirconium diselenide. They share or even exceed some of the very important characteristics of silicon. Silicon has a great property of forming “rust” or silicon dioxide (SiO2) by reacting with oxygen. As the SiO2 acts as an insulator, chip manufacturers implement this property to isolate their circuits on […]

This example shows how to display Bitmap (BMP) image files from SD card on ST7735 1.8″ (128×160) TFT screen using PIC18F4550 microcontroller and CCS PIC C compiler. To build this project we need the ST7735 TFT driver, SD card driver and FAT16 library. The three source files must be added to the project folder (or […]

joint research by the US Air Force Research Laboratory Sensors Directorateand Michigan State University have developed micro-electromechanical systems (MEMS) actuator based on smart materials, specifically vanadium dioxide (VO2). In the room temperature, Vanadium dioxide exhibits the Mott transition. It is a not-well-understood phenomenon known to occur in transition metal chalcogenides and transition metal oxides. The research team was able to use VO2 […]

2 Phase stepping motor driver is a tiny board based on STK682-010 hybrid IC from ON semiconductor and it can deliver current up to 2.5Amp and has supply up to 32V DC. It has multiple micro-stepping: Full step, 1/2th Step, 1/4th Step, 1/8th Step, 1/16th Step, 1/32th Step, 1/64th Step, 1/128th Step.  PR1 trimmer potentiometer […]

Designers can now search SnapEDA’s vast component library directly in PCB123 MULINO, OR and SAN FRANCISCO, CA  (PCB123, and SnapEDA, the Internet’s first parts library for circuit board design, are launching a new integration that allows designers to search for digital models directly inside the PCB123 design environment. Designers have traditionally wasted days creating digital models […]

I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler radar module before and was wondering if I this one is any different inside. The C900502 transceiver has […]

The 3D printing community is growing and innovating each day. Printers are becoming better and better, with higher print speeds, new features and capabilities. It is now time for the 3D printers’ counterpart, the filament extruder, to join the race. Introducing the DNA Extruder, a never-before-seen combination of speed, precision, quality and aesthetics. An entirely new […]

3D printers are one of the coolest and most efficient ways for you to make your ideas go from the drawing board and into real life. Two years ago we launched a new type of 3D printer on Kickstarter. We wanted to make the amazing world of 3D printing available to everyone – not just […]

Essential electronic components, such as diodes and tunnel barriers, can be incorporated in single graphene wires (nanoribbons) with atomic precision. The result is a working electronic device that could be used in Graphene-based electronic switches with extremely fast operational speeds. Chemists at Utrecht University made this discovery together with their colleagues at TU Delft and […]

Chromatron is an open source Wifi pixel controller designed to make LED pixel projects easy and fun. Hi, I’m Jeremy! I’ve designed a toolkit for making art with LED pixel strips, and I’d like to share it with you! Chromatron takes custom designed hardware and feature-packed firmware, sprinkles it with some Python, and serves up […]
