Hoghead,
I have been using a pair of *severely* lightened 8xAA adapters from Radio Shack. (As seen here on CPF. Sorry, I don't have the link handy or remember who gets the credit.) I set them up so that there is a small hole in the negative contact, lined up with the negative contact of the last pair of AAs. So, 6xAA in 2xD space if I put a small nut & screw through the hole, 8xAA without. They're not pretty but they're cheap and have been working well so far. I occasionally get large amounts of AAs for free, so I thought it might be nice to set up a few of my experiments to use them.
All,
The Radio Shacks around me seem to be really slow at re-ordering. There are 3 within about 20 minutes of my house/office. Each location had 2 of each KPR bulb. I bought all (6) of the KPR112s and a pair of the KPR118s.
I was in the first RS I hit yesterday, and in about a month they have not re-stocked the the 2xKPR112s or the 1x8xAA holder. Oh well, they really do have a pretty good ordering system. I used to get AAAAs from them regularly... and I use the ads they send me to start my grill! /ubbthreads/images/graemlins/mad.gif <-- That's not mad... It's FIRE /ubbthreads/images/graemlins/wink.gif
EDIT:
Ginseng,
Thank you for the kind words. Voluminous... Yes, I've been accused of that before. Meticulous? Well, lets just say I use my DMM more for trouble shooting than planning. /ubbthreads/images/graemlins/frown.gif Yeah, the E2s are $$ but a couple boxes of them fell into my lap. I figure, "smoke 'em if you got 'em". I'd hate to feed it "out of pocket" though /ubbthreads/images/graemlins/broke.gif
