switching 5V/1A DC over USB

Hi,

I want so switch 5V/1A DC from Windows over a USB Port. I Think the best Idea would be to use a relayboard with USB connector. I googled a bit for this, but all the things I found were much too expensive (> 100$). Unfortunately I have no COM or LPT Port available (the machiene is a Laptop) so I will need USB. I'm searching for something up to 70-80 $. Can anybody recomend such a Board or has an other idea?

thanks

Andre

Then set one of the handshake lines to drive a suitable relay.

Hi,

thanks for the links. OK, I forgot to mention, I'm in the USA at the moment. I think shipping from the UK will be too expensive.

Do you perhaps know anything in the US?

US to parallel adapters should be very widely available, even in the boondocks....

IIUC they have a chain of electronics shops called Radio Shack?

They're ok if all you need is a cell phone, cheap chinese electronic toy, or overpriced battery. :(
