Ya we had issues with the machine shop !
They screwed up the anodizing on about 50% of the tubes ! DAMN

They are in the mail as I type this so , late dates are looking good .

Sorry we officially closed the guessing all , I cant reopen it now.

Keep your eyes open they will be here soon .
VRubin you coulda won LOL !

I did everything within my power to get these parts on time But it is a custom part and they can take time when A vendor screws up , looking for a new vendor !!!!

hope that's adequate. sorry if not- too fatigued to read 15 pages of posted dates & times!

I *think* that these are the only ones still in the running. Most of us jumped the gun :(. Good luck to those still in it :)

Hi Buzzkill,

Nice looking MOD. I'm guessing this thing will be a hit. I've got a few questions that I didn't see answers for on your site.

1) What are the physical dimensions, length and width of the battery tube in millimeters?

2) How is the voltage varied? Not looking for a real specific answer but... Does the adjustment screw increase/decrease a variable resistor that is placed in the main circuit (such that the full current from the power supply is driven thru that resistor)? Or does the adjustable screw tweek the 'gate' of a more sophisticated voltage regulating circuit that isn't as lossy as a simple resistor in the circuit? (Please don't be offended, just checking).

3) Say you set it to 4v with a pair of fully charged batts. As the batts drain, does the output fall off or will the output remain 4v until the pair of batts fails to provide at 4v (+ some headroom)? How much headroom?

4) The site says you get 6v out of a fully charged 2 x 3.7v stack. Where'd the extra 1.4v go? Does the battery stack need to provide 1.4v headroom over the desired output in order to achieve that desired output?

5) How efficient is the voltage regulator? So how much battery power is consumed by the regulator vs being fed into the atty? And how does the variable adjustment affect that ratio?

Thnx!

Hi Buzzkill,

22mm Dia. 103mm long

2) How is the voltage varied? Not looking for a real specific answer but... Does the adjustment screw increase/decrease a variable resistor that is placed in the main circuit (such that the full current from the power supply is driven thru that resistor)? Or does the adjustable screw tweek the 'gate' of a more sophisticated voltage regulating circuit that isn't as lossy as a simple resistor in the circuit? (Please don't be offended, just checking).

It is a variable regulator adjustment very little current goes through the pot.

3) Say you set it to 4v with a pair of fully charged batts. As the batts drain, does the output fall off or will the output remain 4v until the pair of batts fails to provide at 4v (+ some headroom)? How much headroom?

It will stay @ 4volts until the low battery circuit activates , It then shuts down the device and a red LED will come ON telling you to change the batteries. in the case of a shorted atty the circuit will decrease the voltage to limit the current and the blue led will DIM to let you know .

4) The site says you get 6v out of a fully charged 2 x 3.7v stack. Where'd the extra 1.4v go? Does the battery stack need to provide 1.4v headroom over the desired output in order to achieve that desired output?

It is dropped across the regulator , with 7.4volts when you set it to 3.6v the regulator handles the rest of the voltage.

5) How efficient is the voltage regulator? So how much battery power is consumed by the regulator vs being fed into the atty? And how does the variable adjustment affect that ratio?
the efficiency changes with the set point voltage, the higher the set voltage the more efficient the device is . ( less voltage across the regulator)
Thnx!

This is just like the draw on the batteries on a HV device it;s just that WE CONTROL the output unlike other HV devices.

Please feel free to ask away !:vapor:
