 +===== More components =====
 +It's now September, 2013\\
 +I have managed to get more components working in tandem.
 +
 +I now have the Gumstix booting and transmitting GPS data.\\
 +I'm working on writing a new send program, to minimize data sent.  There are also a lot of xmit errors when you just pipe everything.
 +
 +Here are some pics of the Gumstix running off of battery power.\\

 +
 +I have a Battery pack made out of non-rechargeable batteries.\\

 +
 +You can see a low-voltage meter on the rechargeable battery pack running the computer.\\
 +It's been going a few hours, and it's still going strong.\\
 +I have a better battery monitor coming, but this is encouraging as is.
 +
 +I used an ESC from a model plane to get the 5V to power the Gumstix.\\
 +I had to hunt for the plugin adapter.  I found one in a laptop multi-adapter kit.  I didn't have to butcher the kit to get it working.  I just took a power outlet plug from a Vonage adapter I had lying around to get it hooked up.\\
 +The cabling is too long right now, and I will rig something lighter up for flight, but for now this will do.
 +
 +Currently the Gumstix + Transmitter + ESC + antennas + 8 AA battery pack is around 350g.  Although the batteries are 125g of that, I think I should just consider this the base for my payload weight.
 +
 +I might cut down the cables a little to save a few grams.  The possibility of introducing error with crimping on new SMA ends is pretty hight though, so I may not.
 +
 +Regardless, I will construct a little case for this so that it can be flown on my Bixler for in-air testing.
