Relay's in place

Got a little preliminary wiring done, the relay has been rested, just have to wait for Visual Basic programmer Alex to send me some code to test!

As you can see, the wiring is a mess, however I can assure you it works with a little hyperterminal action done in accordance with the Numato manual page 4-5 available at http://numato.com/productdoc/usbrelay16/usbrelay16.pdf
The next step is to add in the GPIO (General Purpose Input Output) module, following that, I'll need to acquire some PCB (Circuit Board, so I can solder the connections permanently), and put it all together forever.

For review, the Arduino is separated by 1n4002 (you can use 1n4001 for this application, but I had 1n4002 on hand) diodes from the Relay board. The whole thing is powered off a 4 pin Molex connector, so it can be powered by a standard computer power supply. I'm not sure how much power it will consume yet, however I estimate about 200 W once you take into account the 12V 5A solenoids. As a side note, I'm not sure how much heat this set-up will generate, so there's a fan adapter (which conveniently with some squeezing with pliers, was able to fit in the relay screw-downs), in case we need some airflow through the project box.
