Very low power temperature sensor
https://www.electronics-lab.com/low-power-temperature-sensor/
Smartec has commenced selling a new temperature sensor as the successor to the SMT160: the SMT172. The SMT172 has a superior performance, such as a very low power consumption (60 μA) , a very high accuracy (0.1 °C) and a very high resolution (0.1 mK). [via elektormagazine.com] For battery applications, the SMT172 can operate on […]

https://www.electronics-lab.com/quantum-dots-shrink-on-chip-lasers-to-1%ce%bcm/
by Julien Happich @ edn-europe.com Published in Applied Physics Letters under the title “Sub-wavelength InAs quantum dot micro-disk lasers epitaxially grown on exact Si (001) substrates”, the findings from an international team of researchers opens a new route to CMOS-compatible on-chip laser integration. The researchers designed subwavelength micro-disk lasers (MDLs) as small as 1μm in […]
Eagle – Create Nixie tube footprint
https://www.electronics-lab.com/eagle-create-nixie-tube-footprint/
lucadentella.it shows us how to create a Nixie tube footprint by placing the pads in a circular way. I’m working with Eagle to prepare a PCB for a Nixie clock. I wasn’t able to find a library for the Nixie I chose so I had to create it from scratch. Eagle – Create Nixie tube […]
Chrome Apps and serial port communication
https://www.electronics-lab.com/chrome-apps-serial-port-communication/
Luca Dentella writes: During the development of my electronic projects, I sometimes need to develop a graphical user interface (GUI) that talks using serial communication with the devices I create. In the past, I usually chose to develop those interfaces in C# and using the .Net Framework; framework which allows a rapid development, offers great ways to customize the […]
Dark Sensitive Lamp ON/OFF Controller
https://www.electronics-lab.com/dark-sensitive-lamp-onoff-controller/
Dark Sensitive Lamp controller project switches a load connected to it when light falling on LDR (Light Dependent Resistor) goes bellow set point. It could be used as an automatic street light application. The project is based on Triac and doesn’t requires additional DC supply, it works directly on 230VAC. Features Mains supply input 230 […]
How to do serial comms using the cheap RF 433/315 MHz modules
https://www.electronics-lab.com/serial-comms-using-cheap-ebay-rf-433315-mhz-modules/
RomanBlack.com explains in details how to use 433/315Mhz modules for serial communication. These cheap RF modules usually come in a pair, with one transmitter and one receiver. A pair can be bought on ebay for as cheap as $4, and even as cheap as $2 a pair if you buy 10 pairs. Much of the […]

https://www.electronics-lab.com/ltm8053-40vin-3-5a6a-step-down-%ce%bcmodule-regulator/
The LTM8053 is a 40VIN, 3.5A (continuous) step-down μModule regulator. Included in the package are the switching controller, power switches, inductor, and all support components. Operating over an input voltage range of 3.4V to 40V, the LTM8053 supports an output voltage range of 0.97V to 15V and a switching frequency range of 200kHz to 3MHz, […]
LM317 smooths but doesn’t regulate
https://www.electronics-lab.com/lm317-smooths-doesnt-regulate/
Michael Dunn discuss about a circuit that smooths ripple and noise but doesn’t regulates the output. A well known power supply circuit is the capacitance multiplier. It doesn’t regulate, but instead reduces ripple & noise while the output tracks at some fraction of the input vol LM317 smooths but doesn’t regulate – [Link]
Eagle Tutorial – How to add a new package to a component
https://www.electronics-lab.com/eagle-tutorial-add-new-package-component/
Save time by re-using existing packages and symbols . There are thousands of devices in the ‘default’ library that comes with EagleCAD but whaddyaknow, the exact package/device you need isn’t always going to be one of those thousands. However, instead of making a brand new device from scratch every time you can often ‘merge’ two […]
Build an Arduino-Controlled AM/FM/SW Radio
https://www.electronics-lab.com/build-arduino-controlled-amfmsw-radio/
by Raymond Genovese @ www.allaboutcircuits.com: The idea of a single chip radio is intriguing. The prospect is especially interesting to me because, frankly, I envy the analog skills I associate with building a radio receiver. When I browsed the circuit literature in the area, I came across the Silicon Labs collection. One of their chips, […]
