USB Printer Sharing Switch - I had two computers, a Mac Mini and a generic
Windows computer. Both were on different networks, but in the same room, and I wanted
to share a Lexmark USB laser printer between the two of them. I ended up making this
switch to share the printer between the two computers....(schematic / circuit added

USB Self-Powered Soundcard - High fidelity external USB Soundcard / USB
Headphones project that can be built for your PC or Mac. It is based on the latest
PCM2706 IC which functions as a high quality, crystal clear 16-BIT Stereo DAC. It is a
single chip digital-to-analog converter that offers two D/A output stereo channels,
digital S/PDIF output and requires very few external components. PCM2706 includes
integrated USB 1.0 & USB 2.0 compliant interface controller and it is conveniently
powered directly from USB connection. PCM2706 is a USB plug-and-play device and does
not require any driver installation under Windows XP and Mac OSX. ….(electronic

USB Sound Card with PCM2702 - Make a sound card is no more a complex issue.
If you use great IC PCM2702 from BURR BROWN / Texas Instruments you can create a fully
functional USB sound card. This sound card can be powered from USB port and has
one stereo output. You don’t need to install any driver for Windows XP and Vista,
because they are already inside. This is really plug and play. ….(design added

USB to Serial Adapter RS-232 - USB to Serial Adapter RS-232 Serial Port to
USB The USB to Serial adapter (converter) lets you use a serial PDA, GPS, cell, etc.
with a standard USB port. This adapter is the easiest way to add a serial port
to your computer. Many PDAs, digital cameras, GPS units, barcode scanners, and other
equipment require a serial connection, and many newer computers don't have serial
ports. ….(electronic schematic added 11/08) |

USB: a Neat Package with a Few Loose Ends - 10/24/96 EDN-Design Feature
The USB for PCs can automatically configure and power peripherals. But, as I learned
in this hands-on project, early USB adopters may face a substantial system-level
design effort. They also need to carefully examine USB data-bandwidth
characteristics.... [Design Feature by Richard A Quinnell, Technical EDFtor] |
