Well, I've been looking for a suitable container for my LEGO robotic
electronics projects, and I think I've finally found it. I got tired
of dremeling out the inside of bricks, especially since some of my
projects are bigger than the biggest brick.
The solution? I ordered several 9V battery boxes from LEGO S@H, part
#5391. It's a four-by-eight stud box, about 7/8" (22mm) tall.
The bottom hinged cover is easily removed and reveals a space approx.
1 3/4" x 1" x 11/16" inside (27mm x 45mm x 18mm). If one were to
stack two PC boards inside, there's plenty of room for many projects.
It has two rows of stud connectors along the top to attach to the
standard LEGO connectors, and even has a two-stud electrical switch
that would normally engage the battery (which could be used for
something else, like turning on a circuit).
The nice thing is that these only cost US$5.50, which makes them
pretty inexpensive. If you *really* needed more space, you could
even put two together. I'm going to use one to build Dennis Clark's
proximity detector.

| (...) Wow, I assumed the battery box was the one that comes with the 3735 motor kit. It's 4x14 by about 1 1/2" tall. This must use a 9V battery instead of 6 AA cells. (...) And THAT price can't be beat for getting another power connector block too! (...) (26 years ago, 13-Mar-99, to lugnet.robotics)

| I've already built a PIC based controller into one of these and it almost has as much functionality as an RCX, 3 outputs and 3 inputs [1], in a much smaller space! Of course, using all the ports simulaneously does mean using a lot of 1x2 conducting (...) (26 years ago, 29-Mar-99, to lugnet.robotics)
