#127087 - Something a little different Responding to: ???'s previous message |
Since most PCs have a USB port, why not use a USB->serial module and tack the AND gate onto that. You also get the power from the USB cable. Job Done. Something like the items from FTDI http://apple.clickandbuild.com/cnb/shop/...tle=UM232R Or you can hack an 'off the shelf' USB->RS232 converter and remove the MAX213 style chip from it - requires fiddly wiring though. |
