HypnoSquare Instructions v 1.3, May 2009
- 3 -
Part 1: The Good
Part one is assembling the controller PCB. This should be straightforward for anyone who has done PCB work;
there's nothing exotic here.
Estimated completion time: 1 - 3 hours.
We will start with the lowest-profile parts and work our way up, as that allows your working surface to hold the
parts in place while we solder the bottom. Besides that, there is no particular requirement for assembly order.
Step 1: Splitting the PCB
There are two parts to the 8Square PCB, joined together by a small tab. separate the two parts by snapping them
apart (
You can clean up the edge with some snips or a file if you choose, but this is not really necessary.

Step 2: Diodes
The first parts we will place are the 24 signal diodes and single power
rectifier diode.
Orientation is important here
; make sure the black
stripe on the diode aligns with the stripe on the part outline. The red
signal diodes go in the three banks marked D0-D7, D8-D15 and D16-
D23. The blue power diode goes in D24.
