My first solder project, the minty boost!
It's a portable usb power that can charge many things such even my iphone 3g. The minty boost is designed by http://ladyada.net/make/index.html
This is what the minty boost looks like.

My first try is not so smooth. I was too nervous, because I didn't want to mess anything up and I wasn't paying enough attention to what I was doing. So I soldered the IC socket and the schottky diode the wrong way. My solder pencil was too close to the circuit and melted the surface alittle bit.. I have no idea if that caused any additional damage. When I thought finally it's ready for a test run, the board started to smell burnt and I realized I forgot to put in the last piece, converter chip, before putting in the battery. I started to panic and tried to stick the chip in, and the chip immediately got really hot - I forgot to take out the batteries and the current was literally going through my fingers...

my work area

The black thing is the ic socket..it's placed in opposite side. I screwed up pretty early on.

the yellowy part is where the board was melted

looks good, but it's sad that I had no idea it's not put together correctly
The second try was like a breeze, everything was soldered and tested working in under 30 min. I'm absolutely impressed with the creator coming up with this cool idea.
that girl with the coyote life is soooo fascinating!!!!!!!
