- Smart Brick MiniBrain -
The Smart Brick MiniBrain is a smaller version of our other Smart Brick Brains. As with all Smart Brick
Brains, it can be used to control any number of Smart Bricks via a Smart Brick Network. It can be used
when you need to run Smart Bricks, Analog Smart Bricks, or Electronic FeedBack (EFB) Smart Bricks in an
installation which doesnÕt need to be synchronized to an external time code and/or doesnÕt need direct
random access to multiple shows.
The Smart Brick MiniBrain can be used to control shows of up to 1 MByte in length. This translates into
a show capacity of almost ten hours at 30 frames (updates) per second. The MiniBrain can divide the
memory equally into two separate shows. These can be selected by an external input.
The MiniBrain is a small (2Ó x 2-3/4Ó) circuit board. Holes (.156Ó dia.) at each corner allow it to be
mounted on screw standoffs or it can be snapped into Augat 2-3/4Ó Snap Track:

The only indicator on the MiniBrain is the Heartbeat LED that shows that it is alive. It flashes at twice
the normal rate when running a show. A Ê Heads Up Display can be used if you need to see to see the lo-
cation in the show.ÊThis will display the current time into the show.
There are four opto-isolated inputs on each MiniBrain. Any input can be triggered by applying a DC
voltage between 12 and 24 volts to these screw terminals. The first three of these inputs are dedicated
for starting, stopping, and resetting the MiniBrain. The fourth input can be used for either clocking the
MiniBrain externally or selecting between two shows. The dipswitches determine the function of this input.
The inputs can be used in various combinations. If you want to always start the show from the beginning,
you can wire the Start and Reset inputs in parallel. In this way the MiniBrain will always start at the begin-
ning. If you want the MiniBrain to reset when a show is stopped, then you wire the Stop and Reset inputs
together.
If you need to stop or reset a show at a time before the end of the memory is reached, then you
can program one or more digital bits on a Smart Brick and feed these output(s) into the appropriate
MiniBrain input(s). In this way you can divide the memory into as many small Ôsub-showsÕ as you wish, or
