U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a way to assemble transistors based on the 2D materials graphene and molybdenum disulfide. The method etches narrow channels in conducting graphene laid down on a silicon-dioxide substrate. These channels are then filled with a transition-metal dichalcogenide, or TMDC, or more specifically MoS2. […]

Description TritiLEDs are always-on battery powered LED glow lights for general night-time marking use. Radioactive gaseous tritium light sources (GTLSs) are allowed in the United States in several consumer product categories, including watches, compasses, and gun sights, but general-purpose markers are considered “frivolous” and are prohibited. Levaraging advances in LED efficiency, battery capacity, and microcontroller
Infineon will have engineering samples of a 3D magnetic sensor in July. Called TLV493D-A1B6 performs magnetic field detection in x, y, and z direction allowing the sensor to measure 3D linear and rotation movements. The digital I²C interface enables bidirectional communication between sensor and microcontroller.The sensor is for consumer and industrial applications that require 3D

The FTDI connector can be found on just about any ESP8266 design. If you are building a gadget to be deployed somewhere and not a full blown development board, the FTDI connector is somewhat overkill. And it is quite large. A few pins could be shaved off but we still have a through hole connector invading

Heat activated cooling fan controller is a simple project which operates a brushless fan when the temperature in a particular area goes above a set point, when temperature return normal, fan automatically turns off. The project is built using LM358 Op-amp and LM35 temperature Sensor. Project requires 12V DC supply and can drive 12V Fan.

Inrush current or input surge current refers to the maximum, instantaneous input current drawn by an electrical device during its initial turn on. Power converters also feature high inrush currents relative to their steady state currents that may be several times their normal full-load current when first energized. The inrush current of a power converter

Ham radio is a popular hobby and service in which a licensed amateur radio operator explores communications equipment. Typical ham radios do not have bluetooth support, which may be hassle for some. None of the transceiver manufacturers are providing a wireless interface. However, with this ham radio bluetooth interface, communicating and listening to other entity
