I recently graduated and started a new job and it has kept me pretty busy lately and I haven't had a lot of time to hack on my projects. Plus this one is a lot like work, the board design part is probably the least fun, lol. I'm almost done with the schematic, it has been hard to find all the libraries for the parts that aren't already included in Eagle. There was a small trimmer resistor that I ordered that I'm gonna have to make a library for if I can't find it elsewhere. Anyway, I made this project update just to share my current BOM, which is still incomplete (missing the LT3463), but gives a good idea of the price breakdown. One of the mistakes I made that I'm having to workaround is that I didn't order all of the components in the same size. There's some 1206, some 0603, and some 0805 because I sorted by price and didn't think about packages when I was ordering. It's not that big a problem, but I have to be very careful and triple check everything while making the schematic. The total cost of all this without shipping is only $7.14!! Without further adieu:
