[hpsdr] [ATLAS] Gerbers posted...

[Dan Babcock]

Helmut,
 
 A flame suit will not be necessary.  I am sure that Phil and the rest of the group are interested in everyone's comments about the hpsdr project.  
 
 I spent about two hours looking at the Gerber files, especially the power traces, and I do not see any problems.  Maybe it is a problem with your Gerber viewer.  I am using KiCad (07-jan-2006) - Unicode version installed on ubuntu 5.10.
 
 I am not sure the pdf files that Phil posted will give you the best view of the board.

Phil,

Just did a few checks on the Gerbers and I am puzzled!

On Layer 1 the pins 10, 11, 20 are connected to GND?

On Layer 3 pins 1, 2, 11 are OK (+3.3V) but all others are connected 
together without any isolated pads for several power and signal lines?

If I plug my picoPSU-120 ATX power supply into the connector I will get 
a huge surprise.

Has anyone else checked out the Gerbers? Hope this does not become an 
expensive mistake. In my opinion the ATX connector should conform to the 
standard pinout, without having to cut wires in the ATX harness. Since 
this is supposed to be group project it would be a good idea if a number 
of people double check a layout to prevent any errors to slip through 
unnoticed.

Flame suit on, could not stand by and let the Gerbers go out the door 
like that before this is cleared up. No offence intended, I just dont 
see why the Atlas boards need to be rushed through like that. No 
momentum is lost at all, I would not want to order an Atlas alone 
without having anything to plug into it. So it is reasonable to assume 
that people will want to order an Atlas, a Lionheart and a Janus as a 
starting configuration so they can do something useful.
