It was actually a small short that was producting the heat. Basically, the oscillator has no other use but to allow me to practice my morse code sending speed without having to disturb other ham radio operators that may not be willing to work with me on the other end. On the note of using an Altoids tin: I actually use these tins a whole lot for project boxes that involve radio frequency, and also things that may need somewhat of a precise Crystal reference, because the metal does a very good job of shielding the circuit from stray RF, which can get kind of nasty when you work with microwave technology (or, more importantly, keeping out all of the 2.4GHz signals in the neighborhood from getting into a tiny High Frequency mixer, etc). You get the drift, and I will admit that the appearance this go around was somewhat crude, but definitely not "Dangerously useless" :-) Hello,
