I load in the Arduino-as-ISP sketch onto an UNO, then add the cap, then hook it to a Leonardo. I line up the tools as needed, pull up the blink sketch, and try to upload. The 1.5.8 software reports it uploaded! But wait! The Leonardo refuses to blink!
So, I try to upload it to a Duemilanove (and line up the tools for it) with the UNO as programmer and.... (drumroll) AVR Dude chokes after 10 tries with a not in sync error.
I have the 1.5.8 software running on an Xubuntu 14.04 64 bit box.
Is the sketch to make the UNO into the ISP flawed and I'm not told a secret to fix it or what?
