I thought I would post just for anyone who may be doing a 3v Setup.
I was experimenting with some various AAA batteries.
a standard pair of energizer lithium - 2 x 1.5v gives great battery time, about 4 hours.
a standard pair of cheap duracell - 2 x 1.5v gives some good time, about 2.5 hours.
a pair of rechargeable nimh - 2 x 1.2v (still testing on these)
I wasn't sure whether rechargeable AAA would work, but on my new pair i'm working on,
I did a test with 2 x 1.2v Nimh rechargeable batteries and hey presto!
Works perfect!
So even 2.4v of 2 x AAA batteries will light up the entire shoe!
EL lights and LEDs no problem! Super Bright!
Cloneprops was right, a small voltage is more than enough and in my instance,
2 x 1.2v AAA rechargeables are perfect, cheap to get and recharge/replace.
I guess the only thing missing would be some way of having the batteries charge via a charger like you could with 9v, but I figure, it only takes a few seconds to take some batteries out and replace them.
So now thats got me thinking on Coin Cells, i'm pretty sure if I can find some high mah coin cells, it should be possible to further reduce the size of the batteries and therefore remove the need to have them in the soles, and move them externally into a modified ankle buckle, and making a charging point far easier to implement.
Coin Cells will definitely work in powering all the EL panels and LEDs, voltage is not an issue, the issue is battery mah, so will do some further experimenting to find a good combination.
I'll have to do some experimenting on that!
