"All 12x Owners" datasheet updated with the entrance of Hemlock Mike!
Just received my new order of FlexDrives today...
Still V5, must be a typo that Quisp is using a V6??
Is it safe to hit the diode with >300mA from the get go?I set your 'Hot' option to 400mA's as requested...
Probably as long as the forward voltage on your 12X is under 6 volts at that current, it will be fine. But remember that we are pushing the V5 FlexDrives with these builds.
Let us know how it goes on that!
I "hit" mine with 425mA directly (no ramp up). We'll see . . . . .Is it safe to hit the diode with >300mA from the get go?
I was under the impression that these diodes were being "ramped up" to the desired current setting. 400mA is a lot!
I recall reading somewhere about several instances of 8X diodes failing when hit with high currents from the initial -on. Or was that from the "bad" 8X sleds?
I'll hopefully be joining you guys in the 12X club within the next month... if the diode lives!
I "Hit" most of my 8x diode with 400-410mA when turning the pot on the flexdrive v4. I got quite a few jumps between 100mA and 400mA before finally getting the current set. I haven't lost a diode to this yet. Just busted diode windows running into the chip.I "hit" mine with 425mA directly (no ramp up). We'll see . . . . .
The flexdrive CANNOT provide 400mA to these diodes @ <5V VF (voltage to the diode). Drlava is working on a new one now. However, when the voltage begins to approach 6V (like these 12X's do), the flexdrivwe can only actually provide ~300mA. If you want to make a 12X right now, you either have to set it very low or use a Rkcstr or DDL type drive and provide it with at least 6V OVER the voltage drop of the driver. Either that or wait until dlava gets the next generation manufactured.So, I received my BDR-205BK drive and have harvested the diode.
Using the G-1 Glass & V5 Flexdrive and am finding this 12X diode seems to like the higher voltage.
My finding so far are using one 18650 battery (aprox 4 volts) and setting the current to 400ma my output is around 300ma
Setting the voltage to 5.5 volts and driver at 400ma my output is now 390ma. I read something about forward voltage but do not understand this term.
So my question is, what are you guys using for input voltage? I know I will have to drop the voltage into the flexdrive if I go above 6 volts.
Thanks in advance, Doug
