Main Board - $21.95 []

Sewing Kit - $49.35 []


 * Why do we need a 50 dollar sewing kit? We're not at fashion school we don't need this...We will deal with pressure later check the home page for my flow chart of "Milestones". Adhering the board to the body site is not necessary in the beginning, the only thing that must be compressed to a body site are the TECs, this is just simple prioritization of our goals. **
 * The sewing kit contains a few led's and buttons as well as conductive threading that is specifically used for the lilypad to be sewn into cloth and connected to other components. This is probably the main reason we went with the lilypad, because of its ability to be incorporated with cloth-like material. - James Hall **

Breakout Board - $14.95 [] This needs a USB mini B cable to download the programs. We have plenty lying around. - PM **We'll get a couple of these so that enterprising individuals can take home the equipment and play around with it, however we'll limit it to about 3 or 4 in view of our intended total of 8 boards.** Power Board - $14.95 [] How do you connect the batteries to this? Does it need a cable? - PM This is just a 5v regulator that connect a lithium battery cell to the Arduino Lilypad - James Hall **James, is there another regulator we could use that does not cost 15 bucks, what are other options, get back to me..** This five volt regulator has a JST connector, I'll look into how we can implement this into any other type of power source. By the way the sewing kit comes with cell batteries that can be used for the board temporarily until we find out what our final power supply will be. - James Hall

Lithium ion Battery - $6.95 http://www.sparkfun.com/products/731 This is the battery supply that connects to the Power Board - James Hal **How long of a run can we get on this power supply? I would like to avoid ordering batteries until we have set up a functioning and tested device in the lab, after hooking it up and testing the programming and the cooling ouput of the TECs being powered through the wall socket, we'll have a better idea of what are our operational power requirements. The lab power supply lets us avoid the initial need to balance the power/ operational use equation. We'll just test it out and see how much power we need after a couple trial runs...** I had posted this battery because it is a long lasting power supply for the lilypad with a JST connector that plugs into the 5V regulator. - James Hall

Total for one kit $108.75

Power: Battery: for now in class voltage source 2) [] $1.25 Is anything other than the Arduino going to be powered by 5V? The power board listed above has a 5V regulator on it. - PM **This is an indication to me that we're not being conscientious enough if we are listing parts rendered errouneous by other parts... We can do better than this guys.**

**TEC:** **[]** **These are the TEC's we should use, they operate at easily attainable voltage and power.** **- Jon**


 * WILL NEED TO PURCHASE SECOND SET OF THE MAIN BOARD, BREAKOUT BOARD, POWER BOARD**
