Do some research before you spout. The Prop chip has way more features.

Last time I checked the 74xx series has no embedded processors, let alone 8-core ones. So that's a rather pointless comment, don't you think?

how many 74xx would it take to do what the propeller is doing?

Great. A toy chip that can run when it is pretty hot. A lot of the 7400 series can do that too ...

lol so the parallax can run even if you launched it into the sun? JK interesting stuff, especially the color burst part.

wow, so interesting.

No, most mechanical or electromechanical oscillators double as fairly good, if a tad nonlinear, temperature sensors. The crystal's frequency is a function of temperature, that's all. I've ran a crystal (not an oscillator) up to 250C once and while there was a slight (~80ppm) permanent frequency shift after room temp to 250C and back cycle, there was no other damage, and Q remained within 5% of original.

So the crystal isn't permanently damaged by the heat? The picture started getting color again when you opened the door.

You can bake a pizza in there with it also thats getting pretty close to melting the solder if it's that low temp stuff they sometimes use with SMTs.

TIP: Bake some muffins while your at it
