eBay are cheaper: http://www.ebay.co.uk/itm/270957778044 11m, 60 LED, multi colour, £8.35 delivered http://www.ebay.co.uk/itm/140882360285 10m, 100 LED, white, £8.99 delivered The first is the set that I opened up to see what was inside. The second has a much bigger solar panel and is more flexible: it splits the LEDs into two "groups" and can flash alternatively between them, and has more "patterns" including fades on/off. However, having a single 1.2v NiCd/NiMH doesn't convince me I'm going to get much out of it our in the cold - they do seem pretty good indoors but my experience of solar powered LED lights is that they quickly deteriorate in the cold, although I haven't tested these new ones yet. > Not entirely sure you need anything as sophisticated as an Arduino - > http://www.evilmadscientist.com/2007/a-simple-and-cheap-dark-detecting-led-circuit/seems > simple enough :D > There's a big difference between "need" and "want", though. I already have an Arduino gathering dust, and an RPi similarly underutilised. I need something to get my teeth into to make use of them. As I now have 3 sets of the coloured LEDs above, plus two sets of white (which split into two groups as described above), that's potentially 7 separate channels that I can play with. However there is some useful stuff at evilmadscientist so thanks for the pointer. Unfortunately all the circuits I have seen assume somewhat lower voltages than 12v and scaling them is a bit beyond my capability at the moment... -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
