How to build your rhino sequencer.


This is a start.  I will finish the last steps of attaching the wire tonight (thursday night).

Step 0

Find an uncluttered clean surface to work on.

Step 1a

Insert the socket into the top of the board.  The top side of the board has the words "BM99" and "Rhino" printed by the two strain relief holes.  The small cutout at the top of the socket is a pin 1 reference.  You will notice that the copper pad on the board for pin 1 is square and the other 7 pads are round.  It is important to get the socket in the right way so that you will always know which way to plug in the PIC microcontroller.  The picture shows the board top and bottom views.

Step 1b

Turn the board over and solder the 8 pins of the socket.


Step 2

Insert the 5V regulator into the top side of the board with the flat side of the regulator facing the two big holes at the top of the board.  Don't confuse the regulator with the other 5 simillar looking triacs.  The regulator should have one of its leads cut short and the word "zetex" printed on it.


Step 3

Solder and clip the leads off at the back of the board.


Step 4

Insert the 5 triacs from the top of the board.  Pay careful attention to the orientation of the triacs.  The three triacs on the right face the opposite direction from the two on the left.  Solder and clip the leads on the bottom.  NOTE: the lower left triac in the picture is slightly off center.  This one is really easy to insert into the wrong place.

Step 5a

Bend the 5 1K resistors as shown in the picture.

Step 5b

Insert the 5 1K resistors, solder, and clip the leads.  It does not matter which way you insert the resistors.


Step 6

Bend and insert the 2 10K resistors into the top side of the board near the 5V regulator.  Solder and clip the leads on the back side of the board.


Step 7

Insert the blue .1 uF capacitor into the top of the board next to the socket.  Polarity is not important.  Solder and clip the leads on the back of the board.


Step 8

The diode must be inserted with the correct polarity.  Bend the diode at the side with the ring.  The ring side goes into the round copper pad and the other side of the diode goes into the square pad.  The diode "points down" away from the triacs.


Step 9

Insert the big 33 uF capacitor into the top of the board next to the 5V regulator.  One side of this capacitor has a grayish strip with a "0" printed on it.  This is the negative side of the capacitor and must go into the round hole near the edge of the board.  The positive side of the capacitor goes into the square hole.  Solder and clip the leads on the back of the board.
