• I think the most limiting factor would be the length and AWG of the Ethernet cable you connect between the two end points.

• I am a bit confused, in the description it says the forward voltage is 3.4 - 3.6v but then in the features section it says 2.2 - 2.4v.

• I have a DC digital Hakko soldering iron controller. (This one. http://letsmakerobots.com/node/32675) I would love to mod the board into a project box, looks like I could plug my Hakko iron into one of these for a nice solid connector on the box. These look like a DIN 45322 (60'Deg pin spacing), am I correct?

• I believe it will handle 3.3V operation, but you have to power it with 3.3V and use 3.3V serial levels.
In theory you should be able to use any voltage that the PIC can handle, I assume 2V - 5.5V should be a safe window.
Just as long as the power and serial level matches.

• This is awesome but kinda pricey.
He said he spent about \$63 per tile cause of the contest deadline.
16 prototype tiles * \$63 = \$1,008
He said he could get it down to about \$15 to \$35 per tile, lets just say it is \$20 per tile.
16 * \$20 = \$320 (plus the docking module)

• In my GF's Hyundai Sonata the 12V plug below the radio is rated at (12V 10A 120W), that is how I remember.
Volt * Amps = Watt
Watt / Volt = Amps
Watt / Amps = Volt
So your A/C is rated at 208V/230V - 4.18A - 904W, and the relay is rated at 220V 30A.
A/C:
904W / 4.18A = 216V
Relay:
220V * 30A = 6,600W
I think it is well within limits, my only concern is the turn on spike in current, but I am sure it is fine.

No public wish lists :(

In 2003, CU student Nate Seidle fried a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own company. Since then, SparkFun has been committed to sustainably helping our world achieve electronics literacy from our headquarters in Boulder, Colorado.

No matter your vision, SparkFun's products and resources are designed to make the world of electronics more accessible. In addition to over 2,000 open source components and widgets, SparkFun offers curriculum, training and online tutorials designed to help demystify the wonderful world of embedded electronics.
