All the available prototyping shields I've seen are small and I want something that a whole project can be built with so I solved the problem by making a Large Arduino Prototyping Shield
Step 1: Materials Needed
A large prototyping board
A strip of header socket
A strip of header plug
PCB Pins (Wire is OK)
Bits of wire
An Arduino or clone.
The usual small tools i.e.
Pillar drill or Dremmel
Step 2: Connection Extension Pcbs
Two that are 6 by 11 holes.
Two that are 8 by 11 holes.
I made sure I cut and sanded the edges that would be closest so they align without touching.
Step 3: Adding the Pins
Step 4: Adding the Sockets (and Power Feed)
PCB pins are soldered in place one hole to the inside of the Arduino connectors. I guess if you have a different prototyping board then you'll have to work out a different spacing arrangement. The pins poke up from underneath, almost the reverse of how they are normally fitted.
The sockets are then soldered to the row of pins at the height needed to poke clearly through the prototyping board.
The power for the prototyping board is supplied by two sets of wires soldered to the +5V and GND pins of the extension PCBs ready for plugging into the prototyping board in the next stage.
Step 5: Modding the Prototyping Board
Step 6: Adding the Prototyping Board
Simply add glue and carefully position the prototyping board and hold in place until the glue sets.
After the glue has set cut the power wires and connect them to the edge of the prototyping boards power rails. Remember that some of the power rails don't continue across the whole board.
Step 7: In Use
Because I used four separate extension PCBs there is no alignment problem and the Large Arduino Prototyping Shield can be added and removed with ease.
Would I have done it differently now it's finished?
Maybe extending the Arduino connectors to the outside of the prototyping board would have allowed more ICs to be used but only time will tell...
When inserting a component at the lower part of the board it tips up. One day I'll be bothered to glue something to the bottom to support it at the same height as the Arduino.
