Berkeley Lab makes graphene-MoS2 transistor
https://www.electronics-lab.com/berkeley-lab-makes-graphene-mos2-transistor/
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. By Peter Clarke @ edn-europe.com 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 […]

TritiLED – Multi-year always-on LED
https://www.electronics-lab.com/tritiled-multi-year-always-led/
Ted Yapo has designed a multi-year always-on LED replacements for gaseous tritium light sources. 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 […]
Factory programming ESP8266 gadgets
https://www.electronics-lab.com/factory-programming-esp8266-gadgets/
Johan Kanflo’s Esprog pogo pin connector: 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 […]

Heat Activated Cooling Fan Controller
https://www.electronics-lab.com/heat-activated-cooling-fan-controller/
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. […]
Limiting Inrush Current
https://www.electronics-lab.com/limiting-inrush-current/
aimtec.com has a basic article on how to limit inrush current using passive components. 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 […]
