I've been using this very helpful tutorial at highlowtech.org. Without repeating too much of the tutorial this is what I have done so far. I added the ATiny cores to the Arduino IDE. I uploaded the ISP sketch to my UNO, and wired up the uno to the ATtiny85 as per the instructions:
ATtiny Pin 2 to Arduino Pin 13
ATtiny Pin 1 to Arduino Pin 12
ATtiny Pin 0 to Arduino Pin 11
ATtiny Reset Pin to Arduino Pin 10
After trying to upload a blink sketch I got this error. I think the most relevant part is at the the end where it says "wrong microcontroller found".
Arduino: 1.6.0 (Windows 8), Board: "ATtiny, ATtiny45, 1 MHz (internal)"

avrdude: Expected signature for ATtiny45 is 1E 92 06
Double check chip, or use -F to override this check.
Wrong microcontroller found. Did you select the right board from the Tools > Board menu?
I'm used both a ATTINY85V-10PU and an ATTINY85-20PU with the same results. I've also tried using a 1MHz and 8MHz internal clock while uploading. All of these have the same results. There are other people who have had this problem with no solutions. Anyone know what I could be doing wrong?
