MINI PIC GPS DATA LOGGER WITH MICRO-SD CARD
https://www.electronics-lab.com/mini-pic-gps-data-logger-micro-sd-card/
pinko @ blog.exrockets.com has build a mini GPS data logger based on PIC18F25J11 microcontroller. Based on my first GPS data logger I made a new version which is even smaller than the initial design and should be able to fit in any rocket, RC model etc. The new GPS data logger uses micro-SD card and […]
DIY Data logging weather station under $15
https://www.electronics-lab.com/diy-data-logging-weather-station-15/
A Homeschoolers Workbench @ instructables.com has build an Arduino based datalogger that reads data from a DHT22 sensor and logs them on a SD card. In this instructable I am going to show you how to build a weather station that logs the information that it collects on a sd card. DIY Data logging weather […]
ICStripBoard – PCB rapid prototyping tool
https://www.electronics-lab.com/icstripboard-pcb-rapid-prototyping-tool/
ICStripBoard is a innovative cheap tool to enable rapid prototyping of surface mount integrated circuits (IC’s) and allow their usage in prototype electronics projects. Inline surface mount IC’s come in a Variety of packages which are different sizes and these Printed Circuit Boards (PCB’s) have been designed to accommodate the majority of IC’s. Available […]
Send Texts or Make Calls With This Tiny GSM Board
https://www.electronics-lab.com/send-texts-make-calls-tiny-gsm-board/
@ 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. […]
AC Motor Speed Controller for Modern Appliances Using LS7311
https://www.electronics-lab.com/project/ac-motor-speed-controller-modern-appliances-using-ls7311/
The project was specifically designed for motor speed control applications in appliances such as blenders, etc. Tact switches provided for selecting/indicating from 1 to 10 power levels ( Speed Levels). The project is ideal for universal and shaded-pole motor speed control for modern appliances design. Eliminates awkward mechanical switch assemblies and multi-taped motor winding. Features […]
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, […]
