[clue-tech] Anyone know of a computer-controlled USB lamp?

[YES NOPE9]

I found this on eBay.   $12.50

HACK alert  ...........
If you use the TXD output to drive a FET or transistor , you can turn  
the FET  off by sending a break to the USB/serial port.  Removing the  
break causes the TXD output to be high which turns on the FET.  You  
can use the FET to turn the 5V on and off.
I will build one for you if you buy the CP2102 or something similar.
( You can even control the FET by sending a character with a lot of  
zeroes in it.  Like an @ symbol. )  We can set up the circuit so that  
the idle condition ( a high level ) turns on the FET and an @ symbol  
turns it off for for a selected period of time.  Or we can reverse  
that process.
