586  Forum 2005-2010 (read only) / Exhibition / USnooBie Kit - AVR USB Device Dev Kit on: October 27, 2010, 11:25:35 pm
The USnooBie is a microcontroller kit that does not require any sort of AVR programmer or USB-to-serial converters to load and run compiled code. It's hardware design allows the user to develop low cost USB devices with Atmel's AVR ATmega microcontrollers. It can also be used to develop projects which are not USB devices.




Check out more details and all the tutorials I wrote and filmed

Yea I ran into that problem, the although the pictures don't show them, the design files I've posted do include the Zener diodes.

Thanks for the tip, I have since edited the page to exclude that line about the thin iron tip.

There is a ATtiny85 microcontroller on the business card that becomes an USB keyboard pre-programmed to type out text when it detects that CAPS-LOCK has been pressed a few times. It can store about 5K characters using an ATtiny85.

This project is an ATmega chip acting as an USB keyboard that types out the data from a RFID reader (the idea is that the ID strings can be used as login passwords). I used an ATmega168 with V-USB hardware and a ID-12 RFID reader.

591  Forum 2005-2010 (read only) / Exhibition / Wii Nunchuk as USB Gamepad and Mouse on: April 30, 2010, 07:03:01 pm
This projects let's you use a Nintendo Nunchuk controller as an USB gamepad on your computer (a joystick, 2 buttons, and it also 3 axis of acceleration data). It also let's you use it as an USB mouse, but this function can be disabled by a jumper. Tilting the Nunchuk is the same as moving the mouse wheel.

Video, circuit, and code all here:

this is the first day that i was satisfied enough for it to go public, there may be bugs and inaccuracies, please give me plenty of feedback

tested mainly in Chrome, also tested with Firefox and IE
