Fabrication Workshop Followup.

Monday, June 1st, 2009

First let me thank the group of people who came on sunday for the first crack at the fabrication and circuit board workshop. I realize that we spent a lot of time in eagle and not enough time actually doing the etch process. In the future I will probably do a separate workshop for eagle alone.

For this reason I will be available Sunday at TDIs workshop at 833 SE Main #125 for any of yesterdays participants who would like to go over the process of etching the board again and to get some hands on practice.

You are also welcome to come to the TechShop session on june 14th (before carpooling to the dorkbot event at about us).

I have also uploaded the folder with the Anderton superfuzz design files ( http://dorkbotpdx.org/files/fabclass.zip ) and the hobby design rules You should try to run the drc error check and you should notice that with the wider pads a few of the parts will need to be moved.

The 1458 can be replaced with any of the following low noise equivalents (the lt and ne parts are spendy).
