    Mini N.O Momentary Switch ?

    The latter - most atomizers pull somewhere around 1.5 amps (510s draw more) - about 30 times the amperage the switch mentioned is rated for. Using the switch to drive a MOSFET doesn't expose it to the amperage draw of the atomizer and therefore it lasts longer.

    How to make USB Passthrough?

    Voltage. Put one lead on the outside of the atomizer, then check for voltage on both sides of your switch and at the atomizer itself. Something's not right...

    How do you take apart a 510 atty?

    If you're using a digital multimeter and it reads 1 with no decimal places, the ohms are higher than the scale setting - try a higher resistance scale. All my 510s run between 2.0 and 2.3 ohms.

    lenmore power port sale 9.99

    At 750 mAh, it's about 80% the capacity of one 14500 battery - it certainly should last more than an hour.

    How to make USB Passthrough?

    Take a multimeter and test point to point through the passthrough. Check both sides of the switch and the atomizer connector.

    just got the TI "sample" boards

    Folks have done plenty of builds using the 1n4001 rectifier diodes to pull 6v down to 5v. Pulling 8v down to 5v, the LDO regulators seem to be more popular. Now, the trend is going toward using boost converters to push 3.7v up to 5v, which has the advantage of letting you use batteries...

    How to make USB Passthrough?

    You want at least 1 amp (1000 mA) - a variable voltage wall wart is handy because you can 'dial-a-vape'. Note: Due to the VERY small guage of normal USB wiring, you may have to run a higher voltage than advertized to get the proper voltage at the connector. (My example - I have to run 6v on...

    Ah, but will it be "curiously strong" vaping?

    How to make USB Passthrough?

    Boondongle - dig it out of the trash - you only need a couple inches of wire to make the connection. That's how I run my passthrough - except mine is a 220v wallwart.

    How to make USB Passthrough?

    Buy one of these and put a female USB connector on it, then plug in your passthrough.

    The PVMA no more worries for batt connectors!

    Nerf is a poster here on ECF - look at the stickies in the main modders forum and you'll see a thread where he is selling connectors.

    The PVMA no more worries for batt connectors!

    Nerf sells connectors - failing that, you can cannibalize a dead battery.

    The ABCs of batteries

    WH is watt-hours, isn't it? WH / Voltage = Amp Hours 10 / 3.7 = 2.7 Amp Hours, or about equivalent to an 18650 (2600 mAH = 2.6 AH)

    Suggestions for 5v batteries and cases

    That's why I went with a 3AA box for my builds - more working room for components and wiring. How much working room did you have after putting in the RCA connector?

    lenmore power port sale 9.99

    You have to bypass the charging circuit for them to work as a passthrough. You'd have to do a search to find it, I don't recall who it was that posted the info.

    The feedback is definitely deserved - it's a tight, clean build (I wish mine looked half so good).

    Is there a better option for 5v power regulation?

    Nice find, Dave!!

    Chuck vs Lil Chuck questions

    I beg your pardon, Martha - I though you were using the chuck with 2 smaller batteries - my apologies. Yes, you will absolutely see a difference between 3v and 3.7v batteries. With the 3.7v battery, you will see performance similar to the OEM battery for your 510, but it will last longer...

    Chuck vs Lil Chuck questions

    Um, no. You have CR123 sized batteries that are 3v and you have ones that are 3.7v. In the case of the 3v batteries in series, the resistor is there to knock it back to 5v. In the case of the 3.7v batteries in series, you'd need a regulator or a lot more resistance to pull it back under 6v.
