Would people buy this?

Or say that its for switching small signals and whatever people use it for is up to them...

Yeah, I agree that it should be wireless, but in order to set up a whole RF system, its going to be quite a b*tch to do, and the price would skyrocket!  Alot of people are doing home renovations and the like, so it would definately be ideal for them!

The perfect system IMO would be one where you use existing wall switches, hook up an RF module to them, and you can wirelessly control your board to control the modules via remote control or aa keychain remote.  Thing is, thats not gonna happen for my price range...

Update:  Looked into wireless, out of budget.  Looked into ethernet, definately out of budget.  Looked into wireless ethernet, got a sweet idea for a future project; but nonetheless -- out of budget.

Anyways, I burned 10 chips last night with custom firmware, 1 into a USB-NES controller, and 1 other one into some sample USB control firmware that origionally inspired this...

Loaded up the software, tested it out, looks great!  So few parts its actually amazing!  I got so excited to see the LED turn green one way and then red the other way!!!  Could this be the next LED-WIZ?  Probably not due to the limited I/O but sure for smaller panels!

Keep in mind that this can control pretty much anything, input; output; or analog.  Im going to make a custom board for me specifically that is controlled via remote control and the winLIRC software..... so anythings possible!

cholin:
OH!  FORGOT TO MENTION ONE HUGE FEATURE!!!!

All settings are saved in EEPROM!  That means, you set up the software once and you can close it and plug the board into another computer and all the settings will be retained!!!

Just rememberred that right now, tested it out and it works wonderfully.

HID because its already there and it works.  Why would I write a driver for something as simple as IO controlling...  I think the HID is really cool because of the way it works like this.

I don't have much experience with USB and HID descriptors, but it seems like HID would work great for reading inputs, but not great for controlling relays.  From a software programming perspective you could easily read the HID inputs using DirectInput, but how would you programmatically control a relay?   Besides force-feedback how can your software turn relays on and off?

cholin:
If I read this about 30 seconds ago, I could have taken a picture for you.  I just hooked 13 LEDs up to the breadboarded circuit and controlled all 13 of them by the software.

It just works.  The HID is more than DirectInput, its the connection itself, and the way the USB device sends and receives its commands.  I can still send out a custom command like "LEDSON" or something, and read in the data from the device.

DirectInput is just a way of controlling it, mine uses custom software where I send the actual byte directly to the device.
