Time-based One-time Password fob for Google Authenticator
conoroneill.net has coded an Espruino Pico to work like a HID device. Now that the Espruino Pico has (beta) HID support, it can pretend to be a keyboard or mouse (or other HID compatible device). This makes it possible to send characters to the active window on your...

Lasers built on silicon are a step towards fully integrated photonics
A group of researchers from the Cardiff University has demonstrated the first practical laser that has been grown directly on a silicon substrate. by Graham Prophet: The lasing structure was formed in indium arsenide/gallium arsenide layers grown directly on a silicon substrate; the...

LSM6DSL – 3D accelerometer and 3D gyroscope
Two low-power 6-axis inertial modules introduced from STMicroelectronics, the LSM6DSL and LSM6DSM. Both they pack a 3-D digital accelerometer and a 3-D digital gyroscope in a miniature package. These modules consume 0.4 mA in combo normal mode and 0.65 mA in combo high-performance...

Control a High Power 4W COB LED with Arduino Uno
educ8s.tv has published a new Arduino Video tutorial: High Power LEDs are very popular and low cost nowadays so I thought it would be a good idea to learn how control them with Arduino. So, I built a simple project that simply turns on a 4W Cob LED when the button is pressed. When...

The incredible story behind the Gerber PCB file format
Max Maxfield @ edn.com writes about the famous Gerber format and the history behind it. Gerber format is actually an ASCII vector format that defines copper layers, solder mask, legends on a PCB and it's used by manufacturing companies to produce the actual PCB. The incredible...

Raspberry Pi 2 Web Hosting – Full Email Server & Web Server
LDSrelience shared this video on Youtube! This is a short video going over a project I just finished to prove that a Raspberry Pi 2 Model B (new as of February 2015) can run a light duty website and low volume email server. I have installed Apache2 for the web server, which takes...
