Matthew Filipek from Cornell Univercity has build a nice smart watch with 1.7 inch touch screen, SD card, Bluetooth module and various apps. One of the main inspirations for this project was Jared Sanson's implementation of a DIY smartwatch (REF 0). With several design iterations, he...

Serialusb is a cheap (~$5) USB proxy intended to be used with input devices. It is the combination of: a PC software operating the host side of the proxy an atmega32u4 firmware operating the device side of the proxy SerialUSB: A cheap USB proxy for input devices -...

Raj @ embedded-lab.com has posted another great tutorial on how to interface a Nokia 5110 LCD to chipKIT board. Today, we will see how to connect a NOKIA 5110 graphical LCD (used in Nokia 5110 cell phones), which is a 84×48 pixel monochrome display of about 1.5″ diagonal in size....

Boris Landoni shows us how to create G-Code using Eagle PCB design software: To create a PCB with 3Drag , by milling , it is necessary to have the G-Code files for the tracks patterning and for the holes relating to the printed circuit board itself. In this section we describe how to...

Linear Technology Corporation introduces the LTC3643, a bidirectional, high voltage boost capacitor charger that automatically converts to a buck regulator for system backup. The proprietary, single-inductor topology with integrated PowerPath™ functionality does the work of two...

educ8s.tv shows us how to use a servo motor with Arduino UNO: A Servo is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo a coded signal. That’s why we need the Arduino, in oder to send that signal to the...

The LTC3106 is a highly integrated, 1.6μA quiescent current 300mV startup buck-boost DC/DC converter with PowerPath management, optimized for multisource, low power systems. The LTC3106 is ideal for powering low power wireless sensors from rechargeable or primary batteries...

Max Ritter has pointed us to his latest project, the DIY-Thermocam, a open source thermal imager based on FLIR thermal sensor. The results are awesome! The device is based on the popular FLIR Lepton thermal sensor and uses a Teensy 3.2 mikrocontroller to display live thermal images...
