USB digital I/O extender
- Add general purpose input/output lines to your computer based or openwrt
projects! You can control 12 digital input/output lines from USB port using this circuit. Each line can be
individually set to an input or output, and each output pin can be set HIGH or LOW independently, without
changing other output pin states. . . [designed by Peter Jakab]

Use a Printer Port to
Record Digital Waveforms - 06/18/98 EDN Design Idea
(File includes several circuitsscroll to find this one) To record or capture special waveforms, those
that appear once or have no fixed frequency, the usual technique is to use a logic analyzer or a storage
oscilloscope. However, these tools are very expensive. Moreover, because of limited memory, a storage scope
can record fewer than 1000 samples. The technique presented here provides an alternative method to recording
digital waveforms. The idea is to use the PC's printer port to sample waveforms, and the PC's memory to store
data. . . [by Dean Shen, Dycam Inc, Chatsworth, CA]
