This is a simple SD audio player biult with only an 8-pin microcontroller (ATTiny85).

Are you tired with all the initial wiring (power, resonator, ICP, power cap, reset), needed again and again with every uC project? Try this!

An AVR initialization sequence can't be easier with this generator.

A perfect idea to make the microcontrollers prototyping easy.

The Femto OS is a very concise portable preemptive operating system (RTOS) for embedded devices with minimal ram and flash, say 2KB .. 16KB flash and 128 .. 1024 bytes ram.

Great idea - USB scope with only ATtiny 45 for less than 10USD with a homemade pcb. USB is software-based, so no extra USB chip is needed.

A simple open-source USB AVR programmer and SPI interface. It is low cost, easy to make, works great with avrdude, is AVRStudio-compatible and tested under Windows, Linux and MacOS X. Perfect for students and beginners, or as a backup programmer.

If you currently have a STK500 development board, you will face a problem because it doesn’t support any of Attiny24/44/84 chips. You have two ways: either buy STK505 adapter which is quite expensive, or develop your own.

With this small board you can program most of the AVR ATTiny microcontrollers or you can build your projects to use it in a stand alone application. It can be powered with a 9V battery because it has 5V voltage regulator on it.

Some techniques to connect AVR-based device to USB without a specialized HW, just only in the SW way.
