If you have an old laptop or printer power supply kicking around they're perfect...they're usually anywhere from 12 to 16v DC and in the case of laptop power supplies, can output 5A and up...they're just about perfect...then you can grab a glue gun and build this:

How bout a wall plug adapter for the pass thru?

That's what the 12V/2A ac adapter is, a wall plug adapter. Converts 120V ac to 12V dc.

OK, so seriously, from now on, I live in the modding forum. I don't know ... is going on, pretty much ever, but I like it. HAHAHA

so I'm assuming the wall adapter would work?

Yes any wall adapter 12v 2amps or more. I prefer 5 amps. You can also plug these in to the cig lighter in your vehicle.

I sometimes I forget there are other sections in this forum....

Here again, depends on what the output is. If you have one you are considering using, what is the output? Voltage/amps?

You can pick up a 12V/2A very cheap on eBay. Also get the corresponding female DC jack. The plug on the end of the AC adapter is usually 5.5mm X 2.1mm or 5.5mm X 2.5mm. Whichever size you get, you need the corresponding size female DC jack.

It's an wall adapter for usb plugs. Output is 5V at 0.2 A

That won't work, you need at least 2A of output current and preferably greater than 7V.

Well the search goes on, lol But I'll be making some trips to the thrift store now, lol

That won't cut it, the minimum specs of a wall adapter for an LM2596 PT are (at least what you're going to find out there):

Volts: 12V DC (must be DC, higher V is fine but no more than 24V, the LM2596's upper input V is 30V I believe but why push it)

Amps: 2A minimum, but shoot for 3-4A, in the world of adapters bigger "is" better...our gear will only take what it needs but you don't want to be operating your adapter at it's upper limit constantly, it'll just get hot and die an early death...just my opinion...

Well those are the specs I was looking for, lol. Thanx

Got this today to run 3 coil/mesh setups at the same time.

50W 12V 4.16A Switch Power Supply Driver SPS AC100V-240V For LED strip lighting | eBay


Hows this for a desktop passthrough??


I also have a question, i'm in the process of designing a 2 (or 3) 18650 vv box using the lm2596. I think i have the wiring down except for the voltage indicator. I want to use a 3 position on off on switch to display batt voltage and regulated voltage. im planning on having a master on off switch on the positive side and the fire button on the negative. Can i just run a + wire from the master switch to one on position of the 3 way switch and run another + wire from the same position of the master switch to the lm? would i do the same with the + out of the lm to the 3 position switch and to the + of the atomizer connection?? AHHH I'm rambling, ill draw a picture of what i mean

Now that's a power supply!...that'll work careful on those exposed AC terminals...

As for the V meter switching, I think this is right...

...a little hard to see, sorry

Dang, BJ! How'd I forget your wiring when I did my Desktop Box I can read batt V/output on batteries; but only output on AC (I know, AC is 12V; but ma lights don't light up on that combo of switches, just don't seem right)

 

[Badical9]

all you guys rock, i am a comolete noob to electronics. the most advanced thing I've ever done was to make a 5v box mod. i just bought a breadboard so I'm going to experiment tonight while i wait for the rest of my parts from China

 

[BJ43]

Got a new power supply 12v 5 amps with 4 outlets. Cool, 4 2596 PTs connected.

 

[TomCatt]

Where did you get that BJ?
