I received everything. So far I got the linksys NSLU2 powered up and I attempted to flash openslug on it and it promptly decided it hated me. So more to work on that trying to properly flash another OS on it. The only drivers I need are for my linksys usb wifi card and for the FTDI usb serial chipset. I hooked up my 24 volt transformers to the contactors and they connect with a satisfying clunk. So I went to work on the electronics. First I hooked up the arduino and downloaded the software for macos. Perfect. I uploaded a sample program to it that makes the on board pin 13 led blink. Perfect! So I decided to manually energize one of the relays. I hooked up 5V and GND to the coil on one of them and they connected with a satisfying clunk.
So next the hard part. Soldering up all 3 NPN transistors, resistors and relays on that tiny tiny board. I got it and made a program that in short succession energizes all 3 relays and then releases them. And sure enough - clunk-clunk-clunk ---- clunk-clunk-clunk.
So! So far so good! More to follow. The work on the arduino protoshield is NOT pretty. I almost wish I used a separate board that way I could have had rails for everything. But it works and it's *extremely* compact. Video to follow sooner or later.
