    Soldering Iron Tip

    Even 1/4 lb of good solder will build more than a lifetime worth of mods. Leadfree with decent silver content works very well for me with good flux. Leadfree with too much tin can be a pain and i relegete it to plumbing where i can use lots of flux and a torch for heat. Do not like at all for...

    regulator question

    Looks to be the lm2596 regulator. Needs two or more batteries wired in series. See this thread for more info including a nice wiring diagram: http://www.e-cigarette-forum.com/forum/battery-mods/259577-just-lm2596-users.html

    Soldering Iron Tip

    Keep in mind that solder is most likely NOT leadfree so u still should get some good silverbearing leadfree solder and flux. The "wick" is for de-soldering and a short piece of fine stranded copper wire works well for the same purpose. I use pieces of lampcord wire for this. Free from the scrap...

    Just For LM2596 Users

    Just For LM2596 Users

    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...

    Looks like a trip to the local office supply store for a magnifying ruler to cut up might be in order.

    2AA Box / Opposing Mag Switch / Mega XXL Carto / Charging Port

    Good idea. The solder joint on brass will be more secure too. Something i do not know: will the constant passing of electrical current through the magnets cause them to deteriorate and loose force over time? One of my concerns in a switch like this is the soldered wire is attached to a moving...

    want to add protection to my box mod?

    Here is one possibility. Protection circuit Module (PCB) for 3.7V Li-Polymer Battery (8.5A limit):Amazon:Camera & Photo Many other circuits available. Google "3.7v pcb" gives a bunch of results.

    quick mosfet question

    Just caught the first half of this. My control pin is completely open as i was under the impression this would give 5v with no resistance value. Do i need to ground the control pin for it to work right?

    2AA Box / Opposing Mag Switch / Mega XXL Carto / Charging Port

    Do your magnets actually create the connection? Been contemplating a similar switch but thhe magnets i have seen used were in place of a return spring and not actually providing an electrical contact.

    I'm a soldering junkie... Here's my stash & info

    Been eyeballing this one. Just havent had the cash to pull the trigger. Velleman LAB1U 3-in-1 Lab Unit 370-400 Variable soldering iron+DVOM meter+adjustable dc power supply. Seems like an ideal combonation for a modders bench.

    Question about copper wire in a Genesis type atomizer

    I would think if you "tinned" the length of copper wire.......effectively coating it with leadfree silversoldier then u should be ok. I have thought about soing this but have not tried it. Another option is to put 8-10 wraps of the finest copper wire you have (like one strand of a multistrand...

    Wick materials. Safe vs dangerous.

    Curious how you are attaching the nonres wire and what type of non res. Kanthal and solder dont get along well for me.?

    quick mosfet question

    P mos. Direct to ground with switch only interruption. Caps are cylindrical. Not really sure if they are electrolytic. Could weak battery uch connection be a problem? To me the contacts seem as though they might be questionable even thpugh working. None of the typical underpowerex whone from the...

    quick mosfet question

    Sony 18650 battery. 100uf caps. Maybe time to try the imr batteries? Definitely better vapor than the same battery without the booster but get tde feeling something just isnt right with it. Almost as if amperage is being boosted instead of voltage.

    quick mosfet question

    Ok. Now switching properly. More help needed though. Getting 4.99 v output from the 04050board but output drops to 3.2 v with a 2.0ohm atty installed. Wtf?
