Damn, I'd be happy with 50 sq ft. Only thing I have is a KLS (Kitchen/ Lab/shop)

I put this together today with one of the LM2596's I got in a lil while ago. It's pretty basic, RadioShack 4AA box, button and atty connector from madvapes. There wasn't enough room in the box for a meter so it's adjust to taste lol

Finished my pass through yesterday. Also my first experience with VV.......wow! I was amazed at the difference between 4.2v on the LM2596 vs 4.2 on a fresh charged bat. Eliminating the voltage sag of a bat makes a HUGE difference. I had to turn it down to 3.8v because my 1.5ohm DC carto was too hot to touch. I see a 10 piece order of new boards and a handful of HR cartos in my near future
Post a pic of your pass though Rader, I'm thinking of a PT as my next project, not sure how I wanna set it up tho.
Here is my lm2596 passthru, it can either plug in to a dummy 18650, which fits in my reo, or I rock a carto tank using this old flashlight I modded. The flashlight and the dummy 18650 just have a 2.1mm dc plug on there, and the passthru cord has a female 2.1mm on the end of it. Makes it easy to switch. It runs off a 15v laptop PSU. The box with the board in it sits on the floor and has a footswitch to turn it on and off.

RadioShack:
-3x2x1 Box
DigiKey:
-Cig Lighter plug
-Cable Strain Relief
Madvapes:
-510 connector
-3A Horn Switch
JB SteelStik on the 510 Connector and Loctite "InstantMix" to hold the board in place.
This was a "use what you have available" mod. The box is a bit large for what's inside it, but it still feels good in the hand. Ill be searching DigiKey for a better fitting box for future use. I used all the DC jacks that I had for charging jacks on my 2AA boxes. The next one will just have a DC jack to be able to use a variety of input sources.

Looks good rader! I was thinking of using an RCA jack in my box so I can have different cords, like one for the car and one for the house, not sure how well that'll work out tho

Good to 16vdc and they're small enough to fit nicely into just about any box you wanted. I almost used one in a 2AAA box but decided against it given the charge life of a 10440. Easier to change the battery than to have it on unusable while charging all the time. Here are my 14500 boxes with the charge port.

Has anyone tried one of these? Not very efficient for batteries but could make a small VV PT off 12v in a 1AA box or small tube. The pot looks easy to remove and replace with a pot that has a easier knob.

DC Buck Converter with Voltmeter Ammeter 4.5-24V to 1-20V 2A Voltage Regulator | eBay
The Chinese are getting closer to what we want. This at 3 amps would be great but finally amps and volts on the same meter.

Got a few of these and they work great, no flicker, just two wires and $4.30 shipped.

I believe the LM317 has a 1.5amp limit. Someone here put together a mod using 2 LM317s in parallel. Check to see if there are any LM350 modules, this regulator has a 3 amp limit. Here's the 'poorvari' mod made with an LM350 regulator.
I made a VV PT in a Mad Vapes coffin box with an LM350. That's what I originally bought DC jacks and 12V 2A AC adapters for that I use for my ACDC.
ETA:
These are linear regulators, so they buck voltage by generating heat; going from 12V to ~4.5V with my coffin box PT makes a dandy little hand warmer.

Does anyone know of a supplier of these boards/ displays here in the US? There seems to be a limited selection of these parts stateside, especially the voltage displays. I really prefer not to use ebay/ paypal as I have been shafted by them once before. But it looks like ebay is the best source of these parts.
Discount Vapers has these listed on there site for 6.99 I do beleive. Thats who I get my connectors and switches from. Fast shipping too.

Use the subscribe option under 'thread tools' & you can catch any updates when they happen.
Forgive me if i missed it but as far as extending or adding a knob to the v.adjust screw it appears to be brass. So why not just file down a piece of brass or copper to fit the slot in the adjustment screw and solder it.? If the knob/extension was pre-tinned with solder it could be done with minimal heat transfer to the pot knob.
