I built another bottom feeder, this one is a passthrough. Of course used a LM2696. It's basically the same as the previous build but without batteries. I found a 12v cigarette lighter cord extender at Wallymart for only $5 that works perfectly.
I also added the middle section of an 18650 battery holder to keep the 6ml bottle snug in place. I still need to get some o-rings to put at the bottom of the threads in case of any seepage but so far it holds juice and feeds very well through the small loop of hose.
The blue LED's are from China, they only have two wires that are already connected and it will read 3.3-30v for only $2.78 each, not a bad price compared to the LiPo1s-6s ones everyone else has been using all along. The LED's come in a few colors as well, I just liked the blue.

It is getting very easy to make a VV mod.
I built a mod for a friend that wanted dual outlet with this board about 10 months ago and he is still using it.I know, it's not a LM2596; but it is 'plug-n-play'

So this is where all my friends go when they get tired of vaping the laundry![]()
First off, you don't want to hook a PT into a computer. Most USB ports on a computer are only rated for 0.5A. You want a powered USB hub to run a PT.
Next, you need ~2V more input over output; so with the 5V from a USB source, you'll only have a max of 3 - ~3.5V.
For LM2596 PT, just use a DC jack and AC adapter. My ACDC mod uses a DC jack and a 12V/2A AC adapter.
