Somehow my gmail missed this post. ?? Anyway, I didn't post a price point because a) I hadn't computed it, and b) I think it would depend on a couple factors, incl. batch size and being able to find an alternate flash chip sourceable from a cheaper supplier.
In any case, responses to the form so far indicate a potential need for 38 REX units. The flash ships get significantly cheaper at qty 30, so using that number, I calculate that parts cost should be around $20 per board, including shipping and misc consumables. So, let's just assume the rough price point doesn't exceed the original $60 per unit. This point would still allow smaller runs to be made and sold at or below that price, but larger runs might be doable for cheaper. I didn't record the total time it took to build my first board, but it wouldn't representative anyway. I think with a good workflow, I could get it down to ~45 mins per board, possibly lower if I buy a better vise and the castellated board works out (thanks Stephen!), programming gets sped up, etc. I'd be willing to crank out some boards for that kind of money. I also don't know if any interested parties want any compensation for the design or software (I haven't asked yet, but I think it should be asked. Building units for one's self is different than building them for sale, IMO). So, assume $60 per unit. :) -Josh On Sat, Sep 30, 2017 at 11:07 PM, Mike Stein <[email protected]> wrote: > >> I think a rough price point would be useful; why is that a problem? >> > >
