I have been experiencing problems with the DIY USBtiny. When I first assembled the USBtiny, I successfully managed to burn the Arduino boot loader onto a Attiny 85 [proving I assembled it correctly]. However, when I tried to use AVRDude in Terminal a few weeks later to check a custom bare arduino clone with an Atmega 328p-au it gives me:
Code:
avrdude: Device signature = 0x009500
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may not be reliable.
avrdude: safemode: To protect your AVR the programming will be abortedAnd when I run the check multiple times, the Device signature sporadically changes. I did accidentally short out the USBtiny while attempting to program the new boards with the Atmega328p-au. Could that be the problem? I know it’s hard to diagnose remotely, but would you recommend a new USBtiny or double checking the placement of the 328p etc.?

Ooo! Nice work! You've done this sort of thing before
The first thing is to try replacing R4 and R7 with jumpers. Those resistors are only there for use with the SpokePOV. See if that helps.
If not, you might try reducing the bit rate in avrdude with the '-B' option:
You can use the -B option to specify the ISP speed. By default the value is 10 which means 100KHz clock, this is good for target clock speeds > 500KHz. If you want the high speed clockrate [400KHz] for target frequencies > 4MHz you can use "-B 1" to speed up programming. To calculate the SPI frequency from the delay value, use this formula: SPI clock frequency in KHz = 1000/[1.5+B] where B is the delay value. In general, the clock frequency should be at least 4 times larger than the target clock frequency. Try "-B 32" if you're having clocking issues, that should handle even 128khz clocks.

I did as suggested, and unfortunately the USBtiny was still not performing as expected. I tried the classic Arduino as ISP option to verify if my board is smoked. Using the IDE to burn the "Atmega328 on breadboard [8mhz]" I get the error:
Code:
avrdude: verification error, first mismatch at byte 0x0000
0x3f != 0x3c
avrdude: verification error; content mismatchAnd then in terminal trying to verify the board I get:

So the chip is ok. I'm staring at your pictures, and I just don't see anything wrong. The only difference between yours and mine is that I've got the other end of the cable plugged into mine, so that the red wire matches up with Pin 1.
Could it be that you're connected backwards? I don't think it would work at all that way, but I've been surprised before.

To reiterate as well, I am trying to program a atmega 328p soldered onto a custom board design without an external clock.
These latest tests have been performed with an Arduino acting as the ISP instead of the USBtiny to determine whether the board itself is unprogrammable or if the problem lies with USBtiny. When I attempted the same steps with the USBtiny, I experienced a range of signature readings which indicated to me an unreliability with the programmer, hence me using the Arduino.
So far I've gotten further with the ArduinoISP than with the USBtiny, meaning I've been able to at least read the signature of the chip correctly and attempt a burn using the IDE to be cut short with this error
Code:
avrdude: verification error, first mismatch at byte 0x0000
0x3f != 0x38
avrdude: verification error; content mismatchRegardless, I'm stuck. I don't know what the next step would be without another board with another fresh 328p. Any insights or suggestions?
