Omniblox – Eagle BRD 3D viewer
https://www.electronics-lab.com/omniblox-eagle-brd-3d-viewer/
Omniblox is a very good 3D Eagle .brd 3D viewer created by Benjamin D. Richards and David ten Have, but some script knowledge is needed to use it. Looking to render printed circuit boards (PCBs)? Look no further. This script loads and renders them visually using a .brd file created by CadSoft EAGLE (version 6.0 […]
9 VDC Regulated Power Supply
https://www.electronics-lab.com/9-vdc-regulated-power-supply/
Tiny low current 9 VDC Regulated Power supply designed around bipolar transistor and zener diode. The circuit is known as series voltage regulator or emitter follower voltage regulator. The unregulated supply fed to input and the circuit regulate the voltage and provide constant 9V DC, 250mA. The zener diode provides the reference voltage to the […]

Easy Pulse mikro – MikroBus form factor pulse sensor
https://www.electronics-lab.com/easy-pulse-mikro-mikrobus-form-factor-pulse-sensor/
Raj @ embedded-lab.com has designed a new version of his Easy Pulse Sensor. This revision is an add-on board in mikroBus form factor, which enables easy integration with mikroElektronika‘s numerous development boards. It also operates on the principle of transmittance photoplethysmography applied to a fingertip using infrared sensors. Easy Pulse mikro provides all necessary instrumentation and […]
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 […]
