Subject: [alt-beam] Re: Pertaining to the Hextile things. You should really make them
Well, whatever is planned, what are your price projections? I can
understand if you haven't determined that yet. If however you have an
estimate, great. Also how many Hextile & DIPs would likely fit on a
single sheet of PCB, and possibly cost per completed, populated sheet?

was canceled due to snow. Empty parking lots and an accelerator are so
fun! :)
