Here's the version 2 - USB!!!
thats pretty cool, he’s
thats pretty cool, he’s gotta put the resonator on there though…that would only run at 8mhz if not… 
I like his second setup as well…very compact but the underside looks scary with the bare copper wire so close…
I think the little blue box
I think the little blue box near the reset swithc is the resonator. Pretty compact design, kinda freeform BEAMish.

shouldnt be too hard to glue
shouldnt be too hard to glue on something there - except that you probably need another 2x 22pf caps, but they are small.
I guess there is still space
I guess there is still space to add the crystal / ressonator 
Well, fine, if you’re gonna
Well, fine, if you’re gonna actually read rather than guess. ; )
wow! how are they doing the
wow! how are they doing the USB /FTDI conversion?
