[hpsdr] Hermes Connectors

Tue Oct 30 11:16:37 PDT 2012

I plan to put a header in for Alex J15 on top.
like TE [AMP] # 5103309-1 [Mouser   571-5103309-1]
Wish TAPR put in the right angle version for J32 on the bottom [I may 
change out].

If you put in J15 you can just extend an Alex cable or build a longer 
one and directly connect.
Another possible "fix" is an old PC motherboard 10 pin to DB25 serial 
cable for either J15 or J32 and wired appropriately.

I have found a few more errors in the manual and dimensional errors in 
my drawing [will update].

I am in process of mounting in the shell of a defunct CD ROM case with a 
Plexiglas picture frame top until Apollo is available.

We should plan on adding this to Hermes doc's. Another idea is 2 connectors,  DB25 and 26 pin, with stiff wire ala gender changer construction to at least get a convenient connector for Alex (or Hercules). I like the breakout box as you can have access to speaker and other signals via unique connectors for later use. Possibly a small PC board with headers mounted in small hammond box.
