The Cardboard Logic Pad - The basic logic building block for the construction of IO
This is the start of building a Cardboard Logic Pad or CLP for short. The cardboard is found as scrap and the paper fasteners are from any local office supply or big box store. These fasteners take solder very well.
Select the gate circuit that is desired. In this case I am using my basic Nand gate circuit using a npn transistor and input diodes.
Not that many parts to a gate is there.
Just as in a IC, the connections on the CLP are kept standard for ease in wiring and trouble shooting. Due to the amount of solder used, A clip should be attached to the transistor leads as a heat sink when soldering.
A very small work of art and yet can be combined with many more pads to create any logic circuit that you want.
