IDE: Arduino 1.6.2 (with attiny hardware loaded and Adafruit_NeoPixel library added)
My son and I just built a new USBtinyISP kit. I think we did OK. Pictures here:

Plugged it in to my Mac and the green light came on. Ran "System Information" and saw that "USBtiny" was available. This was true both with and without a USB 2.0 hub in the mix. This screenshot is with the hub: https://www.flickr.com/photos/49817980@ ... otostream/
Attempted to wire the programmer to a brand new from DigiKey ATTINY85-20PU by following these instructions (http://www.instructables.com/id/Use-a-1 ... rogrammer/) and here's what it looked like as we tried to use it: https://www.flickr.com/photos/49817980@N08/16400890404/
- Blue is reset (on the USBtinyISP side, this was the slot with the triangle pointing to it)
- Black is GND
- Red is VCC
- Greens are PWMs
- Yellow is ADC1
Opened Arduino.app and attempted to set things up properly:

- Processor: https://www.flickr.com/photos/49817980@ ... otostream/
- Clock: https://www.flickr.com/photos/49817980@ ... otostream/
- Port: https://www.flickr.com/photos/49817980@ ... otostream/
- Programmer: https://www.flickr.com/photos/49817980@ ... otostream/
Then tried to "Burn bootloader" only to get this...
- Code: Select all | TOGGLE FULL SIZE
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
Error while burning bootloader.

Miscellaneous notes:
- I tried multiple clock speeds with no difference
- I tried testing voltage coming out of the USBtinyISP and got 5V only when JP3 was on. Sadly I left the jumper on when I set the ATTiny85 back up and it got nice and toasty. I expect it's dead, but I ordered a few as spares because I figured I'd do something stupid.
- I did not do any of the AVRDUDE to AVRStudio setup as I didn't think it was necessary if I was using Arduino.app
- I really did nothing other than described above... I mean that I performed no steps that I didn't document above
Can anyone help?
