MGB: Breaking the laws of physics...

At my work, we design and build electronic circuits for operation at elevated temperatures. Today, we tested a new power supply circuit to a record temperature of 230 DEGC (that's 446 DEGF!). This is more than the temperature you need to cook (or burn!) your pizza.. I was utterly amazed by how reliable it worked with zero failures for 3+ hours. I only quit the test because I wanted to go home..

Sorry if some readers do not share my enthusiasm, but I just thought it is like breaking the laws of physics...

You have the right to remain silent......the Physics Police

I'm not really into this sort of thing but it looks like you're established a benchmark in your field of endeavor.

The big news that most of us can relate to, not necessarily understand completely, but can relate to, is when you break the laws of gravity.

That seems to be really high....most silicon based electronics want to go unreliable at about 220f.

Were you using diamond/boron based electronics?

What pizza did you cook.

Working on it :D

No, just plain, commercial-grade, silicon components, (carefully selected though, after lots of grind and sweat)

I'm assuming there's no solder used! ;)

Solder was used, High-Melting Point type. Survives to 255 DEGC without a problem...

Wow!

Now if you can work out how to keep MGB head gaskets from blowing at that temp (while you're at it, keep the heads from cracking as well)

I'm impressed!
