Still very much in the works. I'd hoped to be much further along with a second-gen prototype by now (actually, back during the holidays when I did most of the extant work, I'd hoped to be into a third generation prototype by now) but as always, I have more projects than time.
And at the moment, with only a very few exceptions (like my office rebuild) it's all customer work or other 'paid' work, like new store product or inventory maintenance.
It's coming. Slower than I wanted, but it's coming.
