DIY dummy batteries/ battery pack for flash

[Trigger Happy]

i've a 5600HSD and a pair of 3500xi, and a mecablitz 20 (something). anyone know how to rig up dummy batteries for the KM flashes so i don't have to turn my house into a battery shop? there're some posts out there about using wooden dowels (cylindrical sticks) that i think we can get from bras basah art shops, with a screw connected to an AC adaptor, but anyone know the sequence of connecting these? i understand that if you get the sequence wrong you can fry your adaptor, or worse, your flash...

smtan, muko, usual E&E experts please help.... thanks!

u wan dummy batteries for?

the KM flashes.. to hook up to an AC adaptor, instead of using AA batts. building them not a problem, just need to know a) how many for the 5600hsd and 3500xi (all 4? or just 2?) and b) if just 2, then which ports to put the two dummies into? dun want to turn into char-siew if i get it wrong.. heh...

think u just need a AC/DC adaptor... else you sure fry your components...

as for putting a dummy in, i suggest u put fuse instead of wood dowels, cos unless u wanna drill a hole in middle of the dowels, else i dunno how u going to do a passthru... u need to series it, not parallel it.

Ai yo just roll paper tightly then cut them to size of AA battery can use a scew on one end then use shrink wrap , or u tight on budget use tape lor

thanks PCYL. i saw this page on some guy's website.. Al something.. didn't think of paper rolls, good idea! but any idea on the sequencing for a KM flash? fill all 4 or just 2 and in what sequence and which bays if only 2?

The last time I did tt for my laptop, the voltage regulator got burnt.

Hehehe.. when I feel rich, I'll try again...

If you dare or can stuff your hand to the battery compartment... better buy those aligator clip.
You just need to clip two...
the + end and the - end.

you can know by seeing the - + sign of the batteries
exmple.
the 4 battery sequence go like this...
+-+-+-+-
tap the end end + and - because actually it goes like this
+(-+)(-+)(-+)-
the () was connected already this is serial connection.

to make 100% sure use a continuity detection to see which one is connected.
a cheap multimeter should be able to. or a light bulb and a battery he..he..
