Which is quite a bit different than the weekend version. I have managed all the desired changes and have cleaned and revised the traces several times. I could only get by to a point and then I had to use wire jumpers. Trying to keep them to a minimum was my goal but unfortunately to get all the features, I had to use several.
At a minimum 7 jumpers are required for the board to function. 5 more are required for full functionality. By that, I mean I have designed the board with optional components. For instance, the power LED and pin 13 LED and their associated resistors can be totally omitted and the board will still function. The same goes for the ICSP header and the power supply itself.
As it stands, the parts cost is hovering around $5 dollars.

These prices are from Tayda Electronics which are the best I can find anywhere. Of course you have to buy 10 of some items (resistors), but even then were talking just pennies.
So I will call this my little Fiverino... to honor the endless stream of stupid derivative names of a... stupid name. Think of it as the big brother to the OSI microcontroller.
