Alrightythen... Copper! I replaced the stainless steel center post with a copper tube, 1/8" OD. Also noticed that I seated the negative contact at the outer edge of the pennies. I left this post a little longer to get a better hold on the LB-loop. The nice thing is that the Vaporesso 510 adapter has a gold plated rivet in the bottom with a hole about 2.9mm ID. A small grind and a taper on the end of the copper tube and it is a contact worthy of of 20 amps! The other end of this rivet is the MOD contact
I now read 0.08 ohms. Definitely need copper on the minus side too. The VT 22 tank has a screw with a 4mm hole through the center. Perfect mount and electrical contact.
As a product, a properly insulated pin push-fit into the rivet of the VT-22 510 adapter. Then a copper adapter that becomes the negative terminal; Pipe with a copper flange tucked inside and silver-soldered. Now you got a trick adapter for the LB.
Oh, and it maintains contact better now too. A sleeve to represent the cell helps. Mine is a bit wonky but the new copper positive electrode makes reliable contact even if it is off center.
Edit:
Since this is not readily available about the Target Mini II... and since I just typed all this out in PM... I'm still impressed with what they packed into this thing!
Temperature range: 200-600F.
Watt range: 5-50
Voltage range: 0.5 - 8.5
Normal resistance range: 0.05-5 ohm, extended range is 0.03-5 ohm*.
MODES;
VW-H VW-N VW-S - Variable Wattage High/Normal/Soft
CCW - Custom Curve - Wattage
SP - Super Player - * this let's you go to 0.03 ohm
VV - Variable Voltage
CCV - Custom Curve - Voltage
SS/NI/TI - Variable temp control - stainless/nickle/titanium
M1/M2 Temperature Coefficient of Resistance [TCR] (enter your own values)
BP - ByPass - direct cell output
SET - Misc. housekeeping settings including auto on/off being optional.
...okay now! For an absolutely proper bake I was able to use the TI variable temp mode at 20W from 370-390F. That was a very easy darkening of the ABV. I think the curve can be tweaked but close enough for a first go. 400F got scary close to combusting.
Turns out I got the positive contact pressure I needed.
If you go back to that image with the copper slugs, the rounded edge toward the MOD is where contact is being made with the, get this, 'rounded' rail loop. The geometry forms a spherical connection with pressure towards positive contact. No more holding the box!
Had readings as low as 0.07 ohms. The connections are staying much cooler too since I limited the power.
As for the power of the Launch Box. I've been here for ten pages pumping the LB highlighting its one shortcoming - cells - ease of use - more expenses. PA and all the wires is the only way to get enough power to a Launch Box! And that is just raw power. Not for the passionate vaper that needs on-the-go convenience in their lives.
In this last 10 pages we have seen, at least I have experienced, the cell upgrade that puts the convenience back into the LB. A little work and Magic Flight could make a revival upgrade. And many thanks and lots of patience from
@scy123 or his excellent contribution of showing a MOD can 'conveniently' power a Launch Box and have serious control. That is definitely unique in the world of Launch Boxes in my book. A breakthrough, dare I say
I simply got lucky in the spring loaded contact when I plug in the MOD adapter. There are two styles of Launch boxes. If you have an old Launch Box, it will require slightly different tweaks. I like the hardware provided by Vaporesso. The upgrade kit along with this dedicated MOD kit can be 2 or 3 simple parts.
