Programmable light controller
Dilshan Jayakody published a new build: The main objective of this project is to design a maintenance free and low-cost light which automatically turns on and off at the predetermined time of the day. To meet the above requirement I designed this controller using ATmega8 MCU and DS1307 RTC. The driver stage of this light […]
A CNC pickup winding machine built on an ATmega8
Davide Gironi blogged about his DIY ATmega based CNC pickup winding machine: A pickup winding machine it is used to wind a guitar pickup. You can find my previous ATmega manual pickup winding machine here This project is a manual / CNC pickup winding machine, built on top of an ATmega8 microcontroller. More details at Davide Gironi’s blog. […]
Low cost TEA5767 based FM stereo radio receiver
Dilshan Jayakody writes: TEA5767 is electronically tuned FM stereo radio receiver from NXP for low voltage applications. TEA5767 based radio modules are now common in the field and this project is based on Samsung TT-502 radio module. The main objective of this project is to design low cost FM tuner based on this TT-502 / […]
Drive a stepper motor with acceleration and deceleration using an Allegro driver on ATmega8
Davide Gironi writes: This library drive a stepper motor using the Allegro A3967 (EasyDriver) on ATmega8. It will also work on the Allegro a4988, and other type of motor driver controlled by the number of pulse received. It features: direction changing speed changing acceleration and deceleration multiple motor driving stop spinning after number of step, […]
Using a USBASP v2.0 as a cheap ATmega8 Arduino platform
JohnLittle writes: I finally got round playing with my AVRASP v2.0 boards. The ones Sleepwalker3 mentioned. Thanks mate! I bought three USBASP v2.0 on ebay for under £1.50 each. They each came with a short cable (5×2 sockets at each end). However, they do not come with the JP2 header soldered on. Solder it or […]
ATmega based pool cleaner robot
Here’s a pool cleaner robot built on ATmega by Davide Gironi: My replacement electronics it is based on ATmega8 micros. The project is divided into two parts: timer cleaning robot The timer contains the 220 AC to low voltage DC current, and it is out of water, his purpose is to start and stop the cleaning pool robot, […]
EGYDuino – Arduino compatible board
Dr. Ayman Shalaby over at Electronics Lab has posted an article describing EGYDuino, an Arduino compatible board that can be build using home process: EGYDuino is a DIY Arduino clone made on a single sided PCB board. It’s simple and cheap to build using home PCB fabrication methods and it’s 100% compatible with Arduino.

It features: wind counter slow startup automatic stop configurable motor speed configurable winds 2 directions This winder has an LCD display that will […]
SD card logger library with log rotation that fits on ATmega8
Davide Gironi writes: This library implements an SD card Data Logger that runs on ATmega. It has a small footprint, so it can be loaded on an ATmega8, leaving space for user code. It supports SD and microSD cards formatted with FAT16. It also features log rotation. The “Petit FAT File System Module” by ChaN […]
A LED Matrix mask built on AVR ATmega8
Davide Gironi blogged about his LED matrix mask built on AVR ATmega8: avr_mask1 wish you a Merry Christmas and a Happy New Year! AVR Mask1 is a led mask built around 74hc595 shift register and 8×8 led matrix, running on an ATMega8 microcontroller.
An AVR Atmega based PID magnetic levitator
In this video Davide Gironi demonstrates his AVR Atmega based magnetic levitator: This is a magnetic levitator implemented using Atmega8 microcontroller. Magnetic levitation is a method by which an object is suspended with no support other than magnetic fields.
An AVR ATmega configurable production line counter
Here’s a production line counter project build on an ATmega 8 micro by Davide Gironi: It has 4 digit seven segment display. It can count from 1 to 9999 pieces. User can program it to emit an alarm when a number of items is reached. Check out the video after the break.
Atmega8 based thermometer build
Andrianakis Haris writes: This is a thermometer I designed for my room, built in a small pack and easy to control. Some basic components used: Atmega8, LM35 for inside temp sensing and DHT-11 for outside temp & humidity sensing. The hardware is designed on a way so that the PCB can be wall mounted. At […]
Tellymate makes serial to video easy
The UK based crew from Batsocks develops and sells open source kits including breadboard related projects. We found a project they call the Tellymate which looks like a simple and easy way to provide plug-in video text output to any MCU project using just an ATmega8 and a handful of passive components. TellyMate is a […]
AVR-based watering system
Deddies Lab needed a way to water their resident Ficus Lyrata on a schedule of one-half liter per week. In order to automate the process, they designed an Atmega8 based control system which activates a water pump at appropriate intervals in order to keep the plant watered. A simple AC plug-in wall timer activates the […]
