You can find all the code and design files in the project archive. It's linked at the top of page five:
Jun 19th 2008 2:35AM Vanilla extract is really easy to make, just be sure you use at least 1 oz (~30 grams) of vanilla beans per 1 cup (250ml) of 40%+ alcohol. This is slightly more than the FDA legal requirement for vanilla extract, but home soaking is less efficient than industrial percolation processes.
There is an illustrated tutorial at vanillareview.com
PS. Yeah! I'm on Slashfood. I LOVE this blog, keep up the good work.
Jun 17th 2008 1:34AM Glad you liked this one. I'd do it in a second if I didn't live in a studio apartment in the middle of a city....
May 21st 2008 1:16AM There are two things you'd have to consider. First, can the MSP430 write 1 mhz (1 megabyte/second +) to the SD card -- probably. Second, can the MSP430's ADC convert samples at 1mhz -- doubtful. I think the ADC maxes out at 256,000 samples per second, about a quarter what you are looking for.
Check out the TI website, though, I've worked with a TI ADC that samples at +20MHz -- that might help out in your application.
May 14th 2008 9:01AM Hi Michael,
Sorry for my delayed reply, I've been without a PC for a few days.
SD cards require that the whole 512 byte sector be read, or written, at once. Try writing your 64 bytes, followed by 448 zeros -- that should net you a successful save.
I just finished uploading the next project in this series, it will be published soon. I show how to write a whole sector, one byte at a time, to get around the memory limitations of the F2013. You can use the SD card as a 512 byte sequential buffer to hold a partial sector while you wait for the remainder of your data.
Let me know how you progress.
May 14th 2008 8:54AM That's a great solution. I'm seeing the micro SD cards more and more. I remember when I thought that SD cards were tiny -- now I want to find a socket for the micro sd cards because the regular size take up so much board space!

and this instructable is cool:
Feb 4th 2008 11:14AM Last week I did a very similar design that was all through-hole. It's here:
I did this design in SMD so the circuit board would fit inside my PC case. PS: I also like SMD because it saves all the time I used to spend drilling holes.
Feb 3rd 2008 2:44PM Hi Per Jensen,
There is a button in the Eagle tool bar that activates the fill layer. It has to be done every time Eagle is started -- it makes the traces easier to see, I guess. It looks like an "X" with green balls on the ends.
Jan 30th 2008 10:43AM I uploaded a full-sized PNG image of the schematic. You can download it here:
Thanks for letting me know about this. I'll be sure there is a full sized schematic image available for download in the future.
