Description
I was elated when the Arduino as ISP sketch was released. I spent about a year with a breadboarded version using zif socket and a nest of wires, bypassing the Arduino bootloader and burning my sketches straight to the chip. It didn't take long for this breadboard setup to become a cumbersome chore, so I decided to make a dedicated pcb to handle it.
The first version had some issues that this one address.
Improvements include:
• Place for a resistor to disable auto-reset
• Large enough holes to use a ZIF socket
• Option to use either a ceramic resonator OR a crystal
Credit should go to Evil Mad Scientist's ISP Shield Kit for the idea of using a 100Ω resistor to disable auto-reset.

Based upon the purple color, it looks like an OSHPark/Dorkbot made PCB. They didn't like your BRD file when I tried uploading it. I think I tracked it down to an overlap due to a ground signal naming near the crystal, and the other issue is the silkscreen, mask, hole overlap on the Sparkfun RGB LED library part. Maybe they'd accept it if I uploaded Gerbers instead of the raw BRD file.
I did manage to CNC mill one myself on some double sided copper clad but I haven't soldered it up yet. My through holes won't be plated so I'll have to be a little careful on making sure the top traces are connected. Anything else I should know about this version?
I've got a single sided Arduino board I'm building for some robotics projects, and to make it single sided with no jumpers I had to loose the ICSP port. I'm making up an ICSP programmer on an IC test clip, but this would be really nice to have as well.
You're correct, I made the boards for this using OSHPark back when it was still the the dorkbot group order.
Did the automatic system reject it, or was it a problem after the order was placed? (I ask because I just tried uploading it through the automated process and didn't get any errors.) Though, when I run the latest version of the dru I get an error on the wire allowing the crystal space to house a crystal or ceramic resonator. I'll have to try and adjust that in a future version.
