Re: Introducing "Draco"
*** Design Change ***
Due to the many request for LuxI I have change the default LED to LuxI. LuxIII will be an option.
Here's a quick explaination of why I sucum to the request.
If we use a constant current converter, then the most logical choice for LED is a LuxI (S-bin). From preliminary data it have consistantly outperform the LuxIII (U-bin) by ~3-7%. Tint (color) is also much more manageable.
However, I do not recommend the LuxI for those individual who selected the uPic converter option. The uPIC basically PWM (on-off-on-off quickly) the LED. During the ON cycle the LED could experience current surge as high as 1200mA. LuxI internal resistant significantly increase when it's driven at > 500mA. LEDs are solid state device it not like incandescent, which is more tolerant to burst.
So if you want to use uPIC option I recommend the LuxIII , which is much more tolerant to that current level.
Shaocaholica: Diagonal knurling is the final production design.
Icebreak: Yes it could be more precise ... actually it could be down to 0.0002" (0.005mm) but then it will carry the cost of "space shuttle" parts.
Final price = Current Price << 3
jar3ds: Runtime:
· ~ hi setting (350mA) = 33 minutes
· ~ low setting (60mA) = 3.6 hours
JimH: You're killing me. The're gonna make me commit to that. Then I'll start doing more R&D with the with the
Micro Jet Engine. Here are some
samples.
At that point Draco will really be breathing out fire.
