I'm assuming you won't need more than that . However, if you do need more current we have: <a href="http://www.linear.com/pc/productDetail.jsp?navId=H0,C1,C1003,C1042,C1032,C1064,P89069" rel="nofollow">LT3473 - Micropower 1A Boost Converter with Schottky and Output Disconnect.</a> That first package costs $2.59 in single quantities while the second runs as low as $2.79 for single quantities. Also, you can get free samples (two of any one chip) from them if you have a business name and such. That's how I got the chip for my buck regulator that I did. It's great for prototyping on the cheap. Luck with that regulator! Demented I did a quick search of LT for you and came up with this:

I'll have them back on the 12th of August. I also need to put together a boost/regulator to bump that 3.7v Lithium Ion to 5V. yeah, they’ll be run in the next dorkbot pcb order.

When are you gonna have it made up? Next board order? I look forward to seeing how it comes out. Nice work. Demented Say, that looks pretty swank! When are you gonna have it made up?
