Made this thing here outa a old battery(tube and connector) a $2.50 cent 3 amp momentary switch from radio shack 1/2 pvc, a old tire value and a plastic piece i have no idea what it was from. Wish i would have cut the battery tube a bit shorter but it still works like a charm.

Looks great....is there pics of "How To" for passthru's? I'd like to make one but need to see how the usb cable is connected, etc.

TIA

Sorry I should have taken pics before during and after. Only got the after. USB cable is pretty easy. there is a red and black wire in it. black is ground and red is your positive. There will be two other wires but they are used for data transfer so i just cut them back. The ground goes straight to the atomizer socket ground. The positves from the USB and Atty Socket go to the switch. I might build another one and take more pictures next time. write up a how to

Yeah - a 5V PT is really easy, as long as you remember NOT to use it with a LR atty...... (And use a 3AMP switch).
Mine is a bit more complicated 'cus I have a little itty bitty switch so I put a MOSFET circuit in it to protect the switch...
But here is a 'Simple' Diagram:

And just so folks understand, the switch could be on the black line and the red/black lines can also be reversed. The atty is not polarized, it doesn't have a +/-.

What are you using to power that thing?

Right now i am Running it off my computer power supply 850 watt antec sig series. I am not running dual video cards right now to i am using a 12 volt 25 amp rail off it to go straight into the variable voltage card. Was kinda worried this thing would heat up but my lazer thermometer has it at no more then 3 degrees over room temp and that it a reading off the digital LED seems to be the hottest part. Vaping right now @ 4.3 volts good vapor and seems to be more flavorful. Nice thing is i can now use my LR atties on my PT that i usually just use when i am mobile. The LR atties pull some amps @3.5 volts they pull more amps then the regular atty @ 5volts.
Now i just got to design a Box for it, got alot of ideas so far but i think i will ponder it for awhile before I build something. Got most of it worked out but it would be really helpful if i could unsolder the leds and move them. Anyways lots to think about.

looks like your power supply is giving you enough amps. i made one out of an old HP laptop power supply and the dang thing does not put the amps i need. once i fire the atty i see that the amps are too fudging low...

yeah going into the card it has a dedicated rail 12 volts 25 amps. So that is for sure enough. Not sure how many amps the card will put out for sure 3 amps cause thats what they rated the ripple at. Output voltage is from 1.25 to 28 volts no higher then your input voltage. Got to have at least 6 volts input. I have to dial up to 5.3 volts to get the same amp reading on my regular atty as i do on my low resistance atties @3.5 volts. Built in amp gauge on the out put is pretty nice, hell this might be the best 20 bucks i ever spent, lol.

Very nice Java_Az! Like the work. I just made one 'cuz my 5V PT died after 1 month. Used a box due to the switch I had... Wish I had used 1/2" tube now...

FYI - I put a 220 ohm resister between the data lines. Even though I use a wall-wart. The resister signals a USB 2.0 + port to use "charge mode" and supply more amps. If I ever plug it into a computer USB connection, it may work better. I think there is a wiki on usb standards and some other threads in this forum on the topic. I use a larger box and a 3 or 5 amp switch like Bubo said.

Thanks, Yeah the 1/2 tube worked out great. Few things i would do different next time. along with the 220 ohm resistor. Some good info there that i didnt Know. Will have to check out the wiki on that. Need to find out the charge spec on usb 2.0 to find out the max amps it can supply. Thanks again for that info, has me thinking for my next build.
