ALEPH 2 PCB (ExpressPCB Format)

[ppereira]

Hi,

I'm posting a copy of the Aleph 2 PCB that I'm about to start building... If you'd like to view or use the file just change the extension from .pdf to .pcb

You'll need expresspcb which can be downloaded for free from

http://www.expresspcb.com

Anyway feel free to use it if you feel it's any good, and if there's something wrong with it please tell me...

I included a capacitor bank in the main PCB to keep the layout as compact as possible. It's fairly easy to remove it.

Thanks,

Here's a picture of the Aleph 5 I just finished:

Another one...

Changed a few things:

-bypassed zener for the current source with .47uf cap
-the capacitor bank can be installed separately (keeping it on the same PCB brings the cost down) by breaking it off from the main PCB.
-capacitor bank was changed to use Panasonic FC 1800uf/50V caps (or any 16mm diameter caps) for a total of 129,000uf

as before please change the extension from .pdf to .pcb to open it using EXPRESSPCB.
