Would it be possible to add a 'Alternate clock source' output pin to the ArduinoISP sketch as per Nick Gammons 'ATMega Board Detector' software here http://www.gammon.com.au/forum/?id=11637 so people who want to program a breadboard ATmega don't need to use an external crystal and capacitors.

Thanks Coding Badly,
Do you think this mod make it into the official ArduinoISP at some point or forever remain a fork?

I reported this potentially serious problem over a year ago...

If that hasn't been fixed by now I highly doubt the AdaFruit fork is going to be merged any time soon.


On a more positive note, I have a version that has lots of goodies, including a clock output, that's about ready to be published.  Unfortunately, work keeps getting in the way.  It will first be published here (TinyDebugKnockBang is actually part of it)...

If you're interested, I think GitHub has a notification mechanism (or you could just bug me once in a while).


On an even more positive note, if you are burning bootloaders, I think Nick Gammon has an OptiLoader version that outputs a clock (or maybe westfw added a clock output).

I had looked at Nick's bootloader but the boot code is hardwired into the sketch so was no use to me for burning a non standard bootloader.
Hopefully I won't be needing to burn bootloader again for a while and for the slight extra cost I will probably buy the ATmega with pre-loaded bootloader.
