Re: DIY: led ring light
SS, i'm using 4 NiMh AAs in a battery pack. 4.5-4.8 volts.
catman, there is no need to go thru the hotshoe. these are on ALL the time. hopefully it'll produce enough light at 4''-12'' to get above the flash sync of 1/180sec, which is too slow for some lenses.
i've also seen the link you provided and the guys ohm values for the resistors are all wrong. for 4.5-5volts you need a resistor of around 75ohms. i got 100 of them at fry's for $1.50.
so far, i've got about $13.00 in this and some time. also have accrued some valuble knowledge. it's been a fun project so far.
i'll post a completed pic when it's finished. like i said--it won't be pretty but it will work. hopefully, to the extent i want. i already have ideas about a second generation tho. |
