Hi,
I'm planning on making an extenal battery + solar power supply for my S90 to be able to take very long timelapse videos and am looking on insight on a couple of points.
1) What is the third terminal on Canon used for? I can see that
Timescience's external battery doesn't have a third terminal so presumably it isn't vital. On the Canon recharger the middle terminal T is marked T, the other two being +-.
2) Attached is the circuit extracted from a knock-off NB-6L battery bought from Ebay. I think it is an over-charge protection circuit rather something that moderates the output - can anyone confirm that? The chip on the left has '8205A 0936MC' written on it and the one on the left has '211OCB CH15'.
3) I've got a couple of these solare panels on the way:
http://www.dealextreme.com/details.dx/sku.17441 which are claimed to output 5V at 130mA. However I am in Australia where we don't really have that much Ozone coverage and so the sun is unbelievably strong compared to what I used to from the UK. In general do solar panels in extreme sunlight put out a higher voltage OR a higher current OR both if they're being overwhelmed by direct very bright light?
Thanks in advance for any advice.
Dan
