JAMF,
To get 24V, simply connect two 12V batteries in series. That is, connect one batt's neg. terminal to the other.s pos. terminal. Then connect the sight's lamp circuit to the other two terminals. Easy Peasy!

Maybe if you have them lying around. 8) I do now how to get 24V theoretically, as I still have the basic knowledge. Like calculating "Tau" for a cap&resistor circuit or resistance of a parallel/serial mixed resistor circuit. It's the practice of the thing.

12V is nigh invisible in the daytime, so it was 12V at night-time for some good shots:

Ah, very nice, thanks. I've been tweaking the color and glow effect a bit, and this is what I have so far:


I'll probably have to tone down the intensity in order for it to look right during the day. We would really need HDR lighting in order for it to look realistic in all lighting conditions (and no matter how much I fiddle with the lighting settings, I can't manage to make the glare filters useful).

(The speckle is from JPEG compression, but I don't know why there's such a sharp edge on the glow. The texture is bigger than that border shows.)
