I'm trying to figure out a couple things. First, can four NPN
transistors be used to form an h-bridge? I was looking in a book, the Robot
Builder's Bonanza, which features a circuit which uses four TIP41
transistors. However, don't most h-bridges use two PNP and two NPN
transistors? What's the difference in the two designs? I was reading over
the article on h-bridges just posted, and found it a tad confusing, as the
diagram was incomplete...
Second, what's the maximum current the handy board can provide
through its motor power connector? Surely someone knows!

| (...) the fuse is rated for about 2.5A continuous. If that is not enough, get one rated for more current, or replace it with a wire and make sure not to short out the nicads, or you'll get 30 to 40 A flowing. -F (29 years ago, 13-Apr-96, to lugnet.robotics.handyboard)
