Boolean Logic module featuring code by Jetroid
Deep Thought is a Boolean logic module with two distinct sections. The upper section features
addressable Boolean logic, with any one of NOT A, NOT B, AND, NAND, OR, NOR, XOR and XNOR
being chosen either via knob or via CV input. The lower section features simultaneous outputs of
NOT A, NOT B, AND, NAND, OR, NOR, XOR and XNOR.
Key to PCB screen print:
n: This signifies NPN BC547 transistors. Note the correct pinout as shown by the half circles.
The PCB shows the correct orientation for BC547. Other similar transistor types can be used,
but please observe the correct pinout.
Please observe the correct polarity of the electrolytic capacitors.

  • Page 3 Pots ‘n’ sockets PCB 1. Place all sockets on the PCB, making sure the ground tabs line up with the PCB’s ground pads – be careful here as there are four different orientations - then place the panel over them. This will assure that the sockets are correctly positioned. Flip the whole lot over and solder the sockets into place.
