Re: Arriving Soon...
LT, a film canister probably won't fit over the top of the MC (I'll check it out later), but oddly enough, the plastic cap from a bottle of Coca Cola does! /ubbthreads/images/graemlins/ohgeez.gif At least it does with the bottles they sell here in the States. I believe someone in another thread mentioned that a particular brand of bottled water has a translucent cap, so maybe that would be the way to go with a travelin' MC. /ubbthreads/images/graemlins/grin.gif
To make the bottle cap fit, the stock endcap needs to be unscrewed, which would leave the circuit board free. Because the circuit board needs to sit firmly against the battery tube for good electrical contact, a little modding might be necessary to make some kind of little pillar, or spacer or something, so the bottle cap would pin the board against the battery tube when screwed down. Also, the switch would be UNDER the bottlecap, so you'd need to unscrew it to change the output level. Maybe that's not such a big deal if you're happy with one particular brightness level and don't change it often.
Now, regarding the photo sensor, /ubbthreads/images/graemlins/thinking.gif I think it's definitely doable, but not in time for this next build. The circuit for the second run of Milky Candles (MC2?) is very different from the old one, and since the design is essentially complete and testing well, I'd be hesitant to go back and rework it at this point. I do know some people had built prototypes of modded first generation circuits that incorporated photocells, and they did seem to work. Maybe the MC3 will see such a feature in the production build... hmm... /ubbthreads/images/graemlins/naughty.gif
As it is, MC1 could run in nightlight mode for 1000 hours, so leaving it on all the time actually isn't that big a deal. And MC2 just might run a little bit longer than MC1 did... /ubbthreads/images/graemlins/wink.gif
