Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

why not just use a parallel port and transistor. you can do all of that at the cost of about $1 per thing you want to control. or you can use a microcontroler which would be allot cheaper then controlling it through computer.
Awesome device - tho it ships from australlia - I'll have to look for something US based. I saw a serial port controlled 8 relay unit for about $116... I dont care if its USB or serial (I'd be using a usb-to-serial cord anyway) as long as I can control it from linux.

you can probably pick up an old pc with a parallel port for $10 if you even need to pay for it. might that work?
Best one I've seen yet, but the amps on that one isnt much... for a 110VAC item, only 500mA max. Heck its 1amp max on the DC side, and my wiper motor at zero load pulls 1.02 amps.Good price tho, still looking...
Soeren, i'm curious, have you built your own modules before, or know how to? I have built my own computer-X10 interface before but never looked into making my own modules for less $.

Quote from: lorddamax on September 13, 2010, 01:57:33 PMWhat exactly could I use the "6 transistor outputs" and "8 i/o lines" for?Whatever you want!Relays, TRIACs, power transistors etc. (might need a tiny bit of interfacing, I haven't studied it in detail.The I/O lines can be used either for (up to) 8 further outputs or up to 8 inputs (could tell the PC that something happened, like when a PIR movement detector detected a "victim" or a mix of both.
There's:http://www.electronickits.com/kit/complete/elec/ck1610.htm8 relays, 4 inputs (tho I'm not 100% sure what/how the inputs work, waiting on an email back)
http://www.sparkfun.com/commerce/product_info.php?products_id=96694 relays, and a "6 channel i/o interface" - again waiting on a reply as to what exactly that is and how it works/how I'd use it
And:http://www.robotshop.com/devantech-usb-rly16-16amp-8channel-relay-module.html8 relays, no inputs, plenty of power
