ADI, Populated

I finally had some time this evening to sit down with my new ADI board and see if everything actually fit (it looked like it did on paper, but you can never tell for sure).

It actually all looks really good, with only one exception -- the potentiometer in the upper right hand corner doesn't fit into its space very well, the holes for the leads are a bit too skinny. I can make it work for the first version, and be perfectly happy with it, but I'll tweak that on the next version (which I've already started modifying, and will include an ICSP header above the processor, in that blank space toward the LCD connector).

Now I'm just waiting on getting a hotplate to do the surface mount parts (which I'm hoping to document for the ADI page). Well, I still have to confirm all the connections with a continuity tester, but I don't expect any problems there. I may be only a day or two from having a working one-board ADI!

Update: Three things, actually. First, by straightening out the legs of the potentiometer, it slid right in, so no changes required there.

Secondly, out of curiosity, I piled all the parts onto the balance to see what they weighed. Including too-long leads on most of the components, and a paper package around my 2032 battery (but no solder), the entire ADI weighs a mere 71 grams. Of course, a case and some wire is still required, but that's pretty light.

Finally, I did a quick sanity-check of the connections on the board, and they all look good. I still have to do a proper checklist, but things are looking very positive for this board actually working like I want it to.
