This low-cost balancing scooter can carry 90 kg at a speed of 15 km per hour over a distance of 10 km. An ATmega32 handles all of the signal processing for the electric scooter.
The main goal for this project was to obtain a vehicle which corresponds in his functions with the well known Segway ™ and to keep costs as low as possible. After switching on the unit, the electronics is in stand by mode. Through shift the handle into the verticality position, driving mode will be activated. The engines are powered and the equipment is balanced. Now you can ascend and drive off.

Designed to replace the antiquated mechanical push button locks on doors, this easy-to-use security system is built around the embedded RFID tags in student ID cards. Of-course any other RFID enabled card could be used, with modification to the source-code.
The system can store codes from up to 20 different ID cards in the ATmega32’s EEPROM but if you need a larger storing capacity an external EEPROM memory can be inserted with adjustments in the schematic and source code. I think its cool how things evolve, and instead of building an access system based on password, you can easily build this RFID system.

kaOS is a real-time, multithreaded, preemptive operating system for the ATmega32 microcontroller, which loads and executes programs from a Secure Digital or MMC card. The system waits for you to insert a card and press the Reset button, at which point a program is loaded from the card and executed. The system supports multiple threads, cross-thread messaging, dynamic memory allocation, dynamic thread creation, semaphores and much more.

On the previous article i said that i am going to build a project to interface a VGA camera from a phone with a MMC memory. Well this project is even more versatile because of its webserver feature trough ethernet. You’ll just need an old cellular addon camera, an Atmega32 microcontroller and an ENC28J60 Ethernet controller. If you keep things tight the final board should be really small. Heck you can even use this as a spy device, and broadcast over ethernet what the camera see’s.

This is top high on my cool projects list, i mean an autonomous mail system ? that’s neat. Powered by an ATmega32 AVR microcontroller the mail system features a PS2 keyboard, a ethernet port and an LCD display for menu navigation and reading/composing of emails. In the standby mode the system checks for new mails on a time basis and alerts you on new mail. The only thing you could add to this project is perhaps viewing of attachments
