@ blog.tindie.com This quad band GSM board is claimed to be the worlds smallest of its kind. We have no way to verify this bold claim but let’s all agree that this is a pretty small board that lets you send texts and make calls. The GSM feature is an addition to the OLEDiUNO Cube […]
The Next-Generation Semiconductor for Power Electronics
https://www.electronics-lab.com/the-next-generation-semiconductor-for-power-electronics/
Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. The semiconductor is promising for next-generation “power electronics,” or devices needed to control the flow of electrical energy in circuits. […]
LASER TRIGGER FOR CHRONOGRAPH
https://www.electronics-lab.com/laser-trigger-chronograph/
“pinko” build a laser trigger for chronograph using PIC18F2550 and LM393 comparators. He writes: I finished this laser wall trigger for my HIGH RESOLUTION AND ACCURACY CHRONOGRAPH. The purpose of this device is to generate the trigger start and stop impulses for my chronograph as soon as an object disrupts any of the laser beams. […]
A 400W (1kW Peak) 100A Electronic Load Using Linear MOSFETs
https://www.electronics-lab.com/400w-1kw-peak-100a-electronic-load-using-linear-mosfets/
Kerry Wong built a 400W/100A electronic load using linear MOSFETs. He writes: I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic load using both MOSFETs. As you can see in the […]
Digital Potentiometer using Optical Encoder – 10KOhms
https://www.electronics-lab.com/digital-potentiometer-using-optical-encoder-10kohms/
The primary application of the project is to replace the mechanical potentiometer with optical encoder which is long life, accurate, smooth in operation. The simple project has been designed around LS7184 quadrature clock converter IC from LSI semiconductor, AD5220-10 Digital potentiometer from Analog Devices, and optical encoder from Burns. Quadrature clocks derived from optical encoder, […]
How to Setup an LCD Touchscreen on the Raspberry Pi
https://www.electronics-lab.com/setup-lcd-touchscreen-raspberry-pi/
circuitbasics.com has a tutorial on how to setup a LCD screen for Raspberry Pi. In this tutorial, I’ll walk you through the process of installing an LCD touchscreen on the Raspberry Pi, step by step. Many LCD touchscreens for the Raspberry Pi include an image file that you can write to your SD card and get […]
CMOS-TTL QUADRATURE ENCODER USING LS7084
https://www.electronics-lab.com/cmos-ttl-quadrature-encoder-using-ls7084/
The quadrature LS7084 Module is a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7084 are converted to strings of a Clock and an Up/down direction control. These outputs can be interfaced directly with standard Up/Down counters for direction and position […]
LTC4380 Overvoltage Protection
https://www.electronics-lab.com/ltc4380-overvoltage-protection/
Thomas Scherer @ elektormagazine.com writes: When it comes to protecting sensitive circuitry from potentially damaging over-voltage spikes and supply surges we usually resort to networks of coils, capacitors, resistors and suppression diodes to iron out the transients. The LTC4380 low quiescent current surge stopper IC from Linear Technology goes about it in a different way; […]

Valencell, a biometric wearable sensor technology company, in partnership with STMicroelectronics, an electronics and semiconductor manufacturer, announced a new highly accurate and scalable development kit for biometric wearables. The kit combines ST’s compact SensorTile turnkey multi-sensor module with Valencell’s Benchmark biometric sensor system. The SensorTile is a tiny IoT module (13.5mm x 13.5mm) that features […]
RGBdigit clock
https://www.electronics-lab.com/rgbdigit-clock/
by Lucky @ elektormagazine.com build a LED display clock able to display temperature, humidity and air pressure. He writes: What do you do when you want to design ‘something’ with a vintage or modern display? A clock of course, and this is our first design with RGBDigits: multi-colour 7-segment displays. With a BME280 breakout board […]
