MyPart, An Open Source Portable Air Particle Counter
https://www.electronics-lab.com/mypart-open-source-air-particle-counter/
One of the most harmful airborne pollutants with respect to human health is particulate matter. Air particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It […]
AC Motor Speed Controller for Modern Appliances Using LS7311
https://www.electronics-lab.com/ac-motor-speed-controller-modern-appliances-using-ls7311/
The project specifically designed for motor speed control application 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 10 […]
TP4056 3V3 Load Share Upgrade
https://www.electronics-lab.com/tp4056-3v3-load-share-upgrade/
A lot of project are battery powered and some of them need dual battery links. Robert on hackaday.io had shared his new project that shed light on this issue. He built an load sharing addon board with the ability to charge the battery while the project is operating. Many Chinese charger boards are out there […]
ZeroPhone – a Raspberry Pi smartphone
https://www.electronics-lab.com/zerophone-raspberry-pi-smartphone/
Arsenijs build a Pi-powered open-source mobile phone (that you can assemble for 50$ in parts). Currently, it costs about 50$ in parts, and all the parts are available on eBay. No BGA or other difficultly solderable ICs are used (with the obvious exception of Pi Zero). User interface is written using Python, and there’s a […]
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 […]
