semester is over

Welp, my spring semester is over, so I’ll have more time to dedicate to the project.

A couple quotes I like on Perseverance:

It’s not that I’m so smart, it’s just that I stay with problems longer.  ~Albert Einstein

The great majority of men are bundles of beginnings.  ~Ralph Waldo Emerson

I’m anxious to get this thing working and automated.  I also have to do some cleanup of the cabling, man is it messy!  I’m not sure how to approach doing this though.  It’ll involve some connectors, headers, etc but I’m really not sure what is out there.  I think I’d like to do a custom circuit board, but that’s a step out from where I am now.

My USB xfer routines back to the PC don’t seem to work at 100% — I occassionally get errors.  Retransmitting the track often solves the problem.  I need to optimize my USB xfer timing, because it must be on the fringe edge of working.  It doesn’t match what I had originally done on paper, because those timings didn’t work AT ALL.  I used basic trail-and-error to get what i have working now.  I’m going to sit down and revisit those routines.
