MMC3630KJ – Magnetic sensor in BGA package
https://www.electronics-lab.com/mmc3630kj-magnetic-sensor-in-bga-package/
MEMSIC has announced the MMC3630KJ magnetometer that integrates a monolithic 3-axis AMR (anisotropic magnetoresistive) sensor and a signal conditioning ASIC into a 1.2 × 1.2 × 0.5-mm BGA package. According to MEMSIC, devices in the series offer the ability to deliver a magnetic sensitivity in a range of ±30 Gauss and achieve a noise level that is […]
Arduino controlled Triac light dimmer
https://www.electronics-lab.com/arduino-controlled-light-dimmer/
diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not really possible due to the large […]
Arduino Inline Assembly Tutorial
https://www.electronics-lab.com/arduino-inline-assembly-tutorial/
ucexperiment.wordpress.com has published a series of tutorials on how to use assembly language on Arduino. This can be pretty helpful if you want to do some advantaged coding on Arduino. An inline assembly statement is a string which specifies assembler code. The string can contain any instructions recognized by the assembler, including directives (we will […]

Thomas Gonnot has published a RGB LED Strip Controller based on STM32F0 microcontroller. The controller is able to power NeoPixel and DotStar protocol RGB LEDs. A simple controller for a RGB LED strip, with independent control of color and intensity. The design is based on a simple STM32F0 microcontroller. It can handle NeoPixel and DotStar […]
Automatic monitor brightness controller
https://www.electronics-lab.com/automatic-monitor-brightness-controller/
Dilshan Jayakody build a auto monitor brightness controller that adjusts your monitor brightness according to lighting conditions. He writes: The sensor unit of this system is build around PIC18F2550 8-bit microcontroller. To measure the light level we use LDR with MCU’s inbuilt ADC. The control software of this unit is design to work with Microsoft […]

Engineers at the University of California are focusing on measuring Sodium, Potassium, Glucose, Lactate in an attempt to measure an individual’s health. The team have developed a prototype that comprises a flexible printed circuit board holding five sensors. A new device is able to calibrate the data based on skin temperature and transmit the information wirelessly in real […]
28.8MHz TCXO with +-1ppm Stability
https://www.electronics-lab.com/28-8mhz-tcxo-with-1ppm-stability/
Craig document his process of building a Better RTL-SDR TCXO with +-1ppm stability over 0C-55C range. Its hard to beat the cost and versatility of the ubiquitous RTL-SDR dongles, but the temperature stability of their reference oscillators isn’t sufficient for some applications. While the internal 28.8MHz quartz crystal in these units can be replaced by a high […]
