After building a three mode active cooled 650nm http://laserpointerforums.com/f50/loc-active-cooled-handheld-3-phases-55914.html unit I ran into problems with finding a happy power supply for that unit. I'm using a groove 2 driver BTW.
The standard 3 AAA would only give you 4.5V that was a little anemic for this build it would put a drag on the 1st mode with lazing and fan running:undecided:
However the single modes of either lazing or just cooling was fine even with Li-primary's.
Next, I tried the 3 10440s combo netting over 12V to the driver... while the data sheet on the groove 2 states to stay at 12V or under I went into
the 12.50 to 12.25V that the 3 10440s produce fully charged. The driver could handle it, but it was not happy at all and even while it is active cooled the unit got very hot, understandably so.
I was in a quandrum on what to do, knowing I need around 6v to make this unit run in it's schweet spot, well here is the mode.
It is housing 2 cr2 batt rechargeable putting out a little over 6V.
I used a old dilda I had laying around cutting the housing to a length that would work for spring loaded 3AAA flashlight host. The o-rings not only center the batt. housing they also give for a proper seating (no rattling,perfect fit).
I haven't tested for current draw and when I do get time I'll post that
in the thread given for this build. Thanks for looking.
P.S. If any one has some old dilda V1 laying around PM me I will pay some bucks for them.:yh::shhh:
