Davide Gironi demonstrates his DIY A4 laser engraver made from a scanner and a printer using ATmega328: This “Get Ready For Win98″ Laser Engraving Machine it’s built using an old scanner, and an old printer. A laser engraving machine is a tool that uses lasers to engrave an object. A DIY A4 Laser Engraver using […]
XLR8: Arduino-compatible FPGA-based Application Accelerator
https://www.electronics-lab.com/xlr8-arduino-compatible-fpga-based-application-accelerator/
XLR8 has both an ATmega328 clone and custom accelerator blocks on an FPGA and uses the standard Arduino IDE for programming. XLR8 is a drop-in replacement for an Arduino Uno, but with a twist. It is an Arduino-compatible board that uses a Field-Programmable Gate Array (FPGA) as the main processing chip. The FPGA provides a […]
AVR Programmer Shield
https://www.electronics-lab.com/avr-programmer-shield/
ohneschuh @ instructables.com has build a Arduino Shield that is able to program spare ATmega328 and ATtiny85 mcu using the ISP sketch. Beside my Arduino instructables I also use pure ATmega328 and ATtiny85 microcontrollers. To program them I normally used a breadboard and the ArduinoISP setup with an Arduino UNO or NANO. But this was not the […]
Non-Contact Body Temperature Meter
https://www.electronics-lab.com/non-contact-body-temperature-meter/
One of the most commonly used medical instruments nowadays is the thermometer. The thermometer is used to monitor or measure the body temperature of a sick person. The idea of creating a thermometer started from a device called thermoscope, a thermometer without a scale. Several inventors developed it until Sir Thomas Allbutt invented the first […]
A Xively AMbient QUality MOnitor built on ATmega328
https://www.electronics-lab.com/a-xively-ambient-quality-monitor-built-on-atmega328/
Davide Gironi has build an indoor ambient quality monitor that is able to measure temperature, humidity, noise and brightness and indicate the ambient quality using 4 bi-color LEDs. He writes: The data it is logged to the xively.com platform, and displayed to the user through 4 bi-color leds. It can be used to monitor you […]
Burning Arduino Bootloader on ATMega328 using USBasp Programmer
https://www.electronics-lab.com/burning-the-bootloader-on-atmega328-using-usbasp-programmer/
In this tutorial, you’ll learn how to burn Arduino bootloader on a new ATmega328 using USBasp ISP programmer. Every Arduino Uno Board comes with a microcontroller called the Atemga328P, and they are already pre-program with Arduino Bootloader firmware. Therefore, there is no need to burn Arduino bootloader into those Atmega328P chips again. Here, we will […]
DIY USB Line Power Meter Stick
