Wow! Lots of new info over the weekend. I updated the graph. It's lookin pretty good now!
Looks like I'll have to make more plots!Wow! Lots of new info over the weekend. I updated the graph. It's lookin pretty good now!
They are run at 1.44A in the projector at a 30% duty cycle, I have on doing a burnin test at said 1.44A and so far after a day of burning I haven't been able to detect a drop in power (so it is within 0.5% of what it was this morning). Power output is about 2w depending on if you consider losses from the focusing lenses.
just got this battery today and it still flashes on and off...Yep... the battery couldn't handle the high current draw at that setting...
Put one of these in there:
AW 18650 Protected 2600 mAh Rechargeable Lithium Battery - New Version
That battery will handle over 2500mA's of current draw... (specs say over 5 Amps)
Never know...He put the projector on for awhile and said the heatsink is cooled by fans on the projector, and the diodes on the heatsink range 40-60C...I haven't heard that they are been run that high in the projector. I think they're run at like 600-700mw depending on the setting. Spyderfire has one running at 1400ma putting out 1.2watts... or it might be the other way around.
well I have all three jumpers soldered with the pot maxed out which, according to dr lava, should be give an output around 1200. I'm just gonna keep it at this setting and only do like 10 second burns.Leaning toward a driver issue then...
Have you tried turning it down to 900mA's?
It's supposed to max out at 1000...
Bwhaaat? And it lasted for 5 minutes? These are amazing diodes. I must get one of these.Where did they get these diodes from, the Roswell alien crash? I got one up to 2.2W at 1.8A OMFG! Power measured without a lens, diode did not appear to be damaged from this brief 5 minute test. The calibration accuracy of my high range meter is 10% so it could be low of 1.88W to as high as 2.42W. My guess is it's just about 2W... from a 5.6mm can...
