Thermometer That Pushes Arduino to Its Limits
https://www.electronics-lab.com/thermometer-pushes-arduino-limits/
by gundolf @ instructables.com: Starting playing with Arduino seems simple enough. You can find all sorts of tutorials, instructables, wiring and code examples for pretty much every sensor, component, or module available. So far so good. But when the time comes for building a more complex device, the troubles start. The tutorials for adding multiple […]
Alarm System Powered By Arduino
https://www.electronics-lab.com/alarm-system-powered-arduino/
Dejan Nedelkovski had built an Arduino security and alarm system project that uses an ultrasonic sensor for detecting objects and a buzzer for notification. Components needed to build this simple system are: Arduino board, LCD display, 4×4 keypad, ultrasonic sensor and buzzer. The circuit can be connected as shown in the schematics below. In order […]
Dual-Channel Quadrature Hall-Effect Bipolar Switch Module for Magnetic Encoder
https://www.electronics-lab.com/dual-channel-quadrature-hall-effect-bipolar-switch-module-magnetic-encoder/
The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photo lithographically aligned to better than 1 µm. maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch […]

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 […]
