Hall sensors consume no more than 1.6 mA


https://www.electronics-lab.com/hall-sensors-consume-no-1-6-ma/

Comprising both switch and latch types, the TLx496x series of Hall sensors from Infineon offers precise switching points, stable operation, and low power consumption. At 1.6 mA, the devices consume 50% less power than comparable products, and the 5-V versions consume just 1.4 mA. by @ Susan Nordyk @ edn.com: All of the TLx496x series […]

Touch Weather Station using a DHT22 Sensor and a Raspberry Pi 3 with TKInter


https://www.electronics-lab.com/touch-weather-station-using-dht22-sensor-raspberry-pi-3-tkinter/

educ8s.tv tests the new Raspberry Pi 3 board, by building a simple but useful project. A few months back, the Raspberry Pi 3 board was released. It is a great new board because it now offers WiFi and Bluetooth connectivity out of the box! It uses a quad core processor which operates at 1.2Ghz and […]

A miniature persistence-of-vision board


https://www.electronics-lab.com/miniature-persistence-vision-board/

axio.ms published an update of the board and firmware of their SMD POV display. This device is simply 8 bright SMD LEDs and an AVR uC and makes use of the Persistence of Vision effect. You wave it about, and it writes messages in the air, with no wires, liquids or unpleasant bending! Some would […]

VHF Frequency Counter with PC Interface


https://www.electronics-lab.com/vhf-frequency-counter-pc-interface/

Scott has published a new build: This is the general idea behind how this frequency counter works. It’s so simple! It’s entirely digital, and needs very few passive components. sn74lv8154 is configured in 32-bit mode (by chaining together its two 16-bit counters, see the datasheet for details) and acts as the front-end directly taking in […]

Withings GO activity tracker teardown


https://www.electronics-lab.com/withings-go-activity-tracker-teardown/

nick @ novemberfive.co tears-down the Withings GO activity tracker. First, we removed the battery. This is easy: you can simply open the back of the casing with the included tool or with a regular coin. The included battery turned out to be a Panasonic 3V CR2032 with a capacity of 225mAh. In other words, it […]

Time Machine – A Smart Clock That Does What You Say Using Alexa Voice Service


https://www.electronics-lab.com/time-machine-smart-clock-say-using-alexa-voice-service/

With a controller and a seven segment display, showing the time is not a so special feature, but when this clock can listen to the user and do what they want, that’s what worth highlighting a “Time Machine”. Analysing human voice and take action based on that is not so simple. That’s why using a […]

Public Release of ESP32 SoC The Big Brother Of ESP8266


https://www.electronics-lab.com/public-release-esp32-soc-big-brother-esp8266/

It has been about one year since the announcement of ESP32 SoC and the beginning of its beta testing for some developers. Last Month we covered the release of ESP-WROOM-32 module datasheet,  which promised that “New SDK features, tutorials and example applications will be released over the next few months.”. The ESP-32 datasheet was released […]

LTC Design Note: Dual 9A, step-down μModule regulator with digital power system management


https://www.electronics-lab.com/ltc-design-note-dual-9a-step-%ce%bcmodule-regulator-digital-power-system-management/

Jian Li, Yingyi Yan and Marvin Macairan have published a Design Note based on LTM4675 dual DC/DC regulator. The LTM4675 is a dual 9A or single 18A step-down μModule (micromodule) DC/DC regulator featuring remote configurability and telemetry monitoring of power system management (PSM) parameters over PMBus—an open standard I2C-based digital interface protocol. Its 16mm × […]

Tracespace Online Gerber Viewer (beta)


https://www.electronics-lab.com/tracespace-online-gerber-viewer-beta/

This particular PCB viewer takes your Gerber and drill files and gives you individual layer renders as well as very fancy renders of what your completed boards are going to look like. The tracespace viewer accomplishes all this locally (nothing gets sent to any server!) by converting your files to SVGs. Thanks to the “Scalable” […]
