Lead-Acid Battery Tester, Desulfator & Charger

April 01, 2013 By: admin Category: AVR, Power Supply, Tools No Comments →

Da Pimp is ATmega48-based portable Lead-acid battery tester, desulfator & charger designed by Mikey Sklar. It uses capacitors instead of a transformer for efficient conversion of AC to DC voltages. With input 120VAC, it will deliver 0.5A constant current output and dynamic voltage 1VDC – 100VDC. While 220VAC input will increase its current output to […]

AVRDUDE is great software for programming Atmel AVR Microcontrollers and supports many AVR programmer adapters. Unfortunately, it uses command line tool to transfer .hex file to microcontroller. If you aren’t comfortable typing line command each time you want to program the MCU, you can try AVRDUDESS, GUI Software for AVRDUDE developed by Zak Kemble. This […]

Arduino Based ATtiny85 Programmer

February 20, 2013 By: admin Category: Arduino, AVR, Microcontroller No Comments →

Sometimes, you need only few input and output from microcontroller for your project. If you use Arduino, it would be costly and need more space. For small project like infrared pc remote control, an ATtiny85 microcontroller is good solution. It has 8 Kb flash memory, 6 input/output pins, low power supply at 1.8-5.5V, small 8-pin […]
