what,
How should I choose which tech to learn? I see starter kits for things like this

that seem to be more powerful for the same price. I am serious about learning, but I want to start with...
waht,
That seems like a good approach. Curious, what is the limit on how many relays could be controlled using this method? Right now I only want one, but I am just saying. I would like to have everything in one package, e.g. the usb port/relay/power in and out etc. Would it be smarter to go...
MATLABdude,
Thanks for the response and the welcome. So are you saying get a USB supported controller for sayyyy a usb mouse, and just hack it to drive the relay? You think this can be done for under 5 dollars? I found a solution that uses a PIC but then I need a PIC programmer...

Hello,
I want to make simple USB driven relay but I am wondering if it can be done without having a USB device on the other end. Most solutions I have seen thus far have a microcontroller that drives a relay. I was wondering if I could use a library like libusb to send data directly to the...
