Parts to make a circuit board for HV and computer pulser need to be finalized and ordered.  3 days
Choosing the volts to use for a wall wart UL listed 12 or 15V supply to use.  1 day.
I have a bunch of 12V supplies in the attic that might do (with some big caps to hold up the volts during a discharge).
I have layout to do. 8 days.
More misc connector parts to choose.   2 days
I need to make some kind of safety cover/switch arrangement to use cuvettes.  3 days design, prototype.
Fabbing the cover/switch could be done using a CNC mill in ~1 days for qty ten, then 2 hours for another ten...
I have standard cuvettes to send with the first articles -- courtesy Josiah Z.


The unknowns are getting less and less, so maybe ship to you in 18 days from now.  Oct 19th by USPS.
I can make a bare bones machine for you, leaving off the careful case design and just hacking
some kind of cover prototype for you and probably shave days off that.

I'll send later versions to replace prototypes that are crude.

I'll keep updating that target as things progress.
