First shield: adaptor

After gambling around with shift registers (74HC595) I thought it could be a good idea to build the first shield. Two shift registers shall control the LEDs of a Knightbright LED bar graph.

The first step was an adaptor shield - thanks to Erik Bartmann for this idea (für die deutsch sprechenden Leser: "Die elektronische Welt mit Arduino entdecken" ist eine empfehlenswerte Lektüre). This way I have only one shield with bended pins, and use my future shields with the usual 2.54 mm distance of every pin header.

First step: milling the paths of the striped printed board.
Second step: soldering the pin headers.
Here you see the first header already soldered and the second one in position:

 

The two headers on the left side are only to keep the board parallel to the desk.

Finished, but not cut to size:

 

Now it's time to start with the "LED bar graph shield". At the moment there are only the headers:

And this is the result:
