Some notes on the protocol used by the $30 desk controller.

It's a standard user interface JCHT35K & a standard motor controller JCB35N

Much like the remote controlled GU-24 lightbulb, it's not a huge need.  It would be nice to have preset heights without paying for a controller.  The mane need is replacing the membrane buttons with better buttons on a remote control, in addition to presets.  Those membrane buttons are simply awful.  The remote control would have to be wired to have a decent response time.  

The trick is he didn't reverse engineer any of the commands sent for presets.  It seems the desk writes a constant stream of height codes to a UART.  There could be a preset program that just reads the height codes for feedback.  It couldn't have any proportional feedback.
