Heat...
Well, it's all going swimmingly. My first use for this is a long-duration time-lapse with a digital camera and a computer and it's all coming together. Very exciting.
I had a question about heat: when running, the little thing gets pretty warm -- on the edge of me being able to hold my fingers to it. I have attached a heat sink (see attached pic). The NTE970 that I'm using (the "equivalent" of the LM150) is spec'ed at:
Absolute Maximum Ratings:
...
Operating Junction Temperature Range, TJ . . . .. . 0° to +125°C
Storage Temperature Range, Tstg . . . . . . . . . . . –65° to +150°C
Thermal Resistance, Junction–to–Case, RthJC . . . . . . . . 2.5°C/W
...
...although I'm not 100% of the implications, 125°C seems well above the temperature it's reaching, so I assume I'm well in the clear? I just want to make sure I don't ruin another one of these.
Thanks!

P.s. the picture was taken by the camera being powered by the fake dowel-rod batteries from the unit.
