hello - I am working on a camera project and need help with the electric part of it.
I have an outdoor camera that is powered by a
UB1280 12v battery
The flash on my cameras are weak
So i purchased several slave flashes (neewer slave flash)
this is an example of the flash
http://www.ebay.com/itm/NEEWER-AUTO...era_Flashes&hash=item4abba4657f#ht_3200wt_932
(edit: i should mention the goal is to not have to use the 2 double AA batteries, i'm looking to power the slave flash off the UB1280 12 battery)
They take 2 AA batteries. which is around 3 volts together.
so i purchased a LM2596s "step down" circuit
(not from this buyer, but it looks just like this one)
http://www.ebay.com/itm/LM2596S-DC-...ultDomain_0&hash=item337bde5cbb#ht_2418wt_970
when hook all this up and adjust the voltage down to 3 volts.
i press the test button on my slave flash, and sure enough it does flash.
so it's working
my problem is its the step down module is getting very hot, so hot it's melting the hot glue on the back of it.
this set up is meant to be left outside unattended. and i can't have a fire.
So my questions are, am i doing this right?
is there a better way?
can i do anything about the heat problem?
Thanks!
