The objective was to work around an undetermined hardware/software problem (cross-talk) with the port multiplexer on an IR transmitter by running one of the ports through a computer controlled relay, and using some scripting to force that emitter to be disconnected from the transmitter when not in use. > Powerswitch Tail - $25 > https://www.adafruit.com/products/268 > ...did anyone mention this already? No, it didn't come up. The device is basically an enclosed solid state relay with a couple of 120 V pigtail cords - one plug, one socket. Screw terminals to supply the 3 to 12 VDC control signal. It doesn't include a computer interface. That's nicely done for $26. Not useful for this project, but could be handy in the future. In theory, it should be drivable from the parallel port, per the earlier discussion. (Though with ~3mA drive, it'll require an external supply, buffer transistor, or ganging multiple outputs together.) -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
