Here are two brand new boards for faster prototyping. These are especially useful for these one-off projects that need to be more permanent than on a breadboard. And they save time as most of the standard components as reset button or ISP header are already on board. Only the custom part of the project has to be soldered on the proto area. They come in two flavors, one for ATtiny25 and one for ATtiny2313 Atmel microcontrollers.
You can grab a full kit at the Tinker Store (sorry, shop is closed), if you like.
