Thanks for that Gert!
I was actually joking about the “overclocking”. I'm really sorry if I caused any offence!
In fact, you're the only person I know who has expressed any
concern at running at a mere 2% overclock. Everyone
else runs their 3V3 ATMegas at 16MHz (a 33% overclock!) with no concern at all! What's even more bizarre is that they all seem to work! Of course, the questions are: how reliably and for how long?
I certainly strongly
respect your “rock solid” design choices! They have led to the Pi and the Gertboard being amazingly solid and reliable bits of engineering. As you say, “...if I stick to the specs the device will work under all circumstances”.
I think there's a lot of scope to educate people about “good design” and why it's important.
Also, having just written some interrupt driven code code for the ATTiny85 I know completely understand your comments made at the Cambridge Jam before last about the ATMega being very useful for teaching interrupts from the ground up (in addition to a load of other things of course).
Finally, my original comment about damage to the space-time continuum is based on http://www.bbspot.com/news/2000/5/clock_rift.html
(it's well worth a read, it's a fantastic bit of satire).
