Since I discovered the Arduino micro-controller last October (2010) I have been fascinated by their versatility and ease of use, however I personally find that they tend to be on the bulky size and expensive for some of my permanent projects. I then discovered the Ardweeny and I just love their size and price; after purchasing a few, I made some personal improvements, especially after blowing the ATmega328 on one of them and finding it a pain in the derrière to replace it.
The concept is simple: reverse the PC board and solder the components on the opposite side, this way a socket for the ATmega328can be added along with some strip headers for versatility.
These modified versions are meant to be used in small permanent projects, they are not suited to be used in bread boards like the stock units (although with two strips of long male headers they could be used that way) keep in mind that the serial interface is obstructed making them inconvenient to program while installed in the bread board.
If you wish to use them in bread board, follow the kit instructions to the letter, my only suggestion and recommendation is to add female headers instead of the provided strips, see step 4 - Installing the Female Socket Strips, this way you get an extra set of connections to use when plugged into a smaller bread board.
Step 1: Tools and material:
What is needed:
1 Ardweeny kit
1 28 Pin DIP Socket
2 Female Socket Strip - Strip of 6
2 Female Socket Strip - Strip of 8
Optional: different color LED (I like blue :)
Soldering Iron and solder
Precision diagonal cutters
Step 2: Installing the first components
IMPORTANT NOTES :
From here on just follow the instructions that come supplied with the Ardweeny except that you need to install the component on the opposite side of the small PC board , the one without the white labels and take your time to make sure you install the components in the corresponding assigned holes.
