    The Pyrex SS hybrid Wick

    Here's another thin wall option. From the nominal specs, it would be a .15mm wall. 2.5 mm OD Precision Capillary Tube, 400MHz | Wilmad-LabGlass

    Gripper Discussion

    I'm sayin ZMax guts (or at least the same functionatity) with LiPoly battery and onboard charging. The battery door has been one of the biggest complaints about the Gripper. Solution: scratch the door.

    The Bolt

    The kick is only more stressful on the wiring if you run it at max power (10w) with a LR coil. If you vape at a more modest 8w or less, straight battery is more stressful than the kick. Use a SR coil and it is much less stressful.

    Watts - same same but different?

    I'm hanging in. Pretty good at holding my own. ;) Dead Horse: I realized long ago that there is no single answer to the riddle. My only doggy [dogie] (:rolleyes:) in this race is that the conventional logic of calculating battery drain current using the the output values, and then concluding...

    Watts - same same but different?

    The voltage is regulated based on the desired output voltage. Output is constant, so the losses are calculated on the input side of the equation. Voltage is a set value by the battery charge, so the losses present themselves as increased current, not as increased voltage. In that post I used 90%...

    Watts - same same but different?

    A wise man once said: "Keep your words sweet, because you'll never know when you'll have to eat them." Woof, woof.

    Watts - same same but different?

    I don't see the humor in my post. Care to share the punch line?

    Watts - same same but different?

    Not true. There is a power conversion that takes place. Output current DOES NOT equal battery drain current. In an ideal (not factoring efficiancy losses) device, battery drain current would be equal in those 2 examples.

    28 ga a-1 kanthal

    On a 3/32" drill bit, a 6/7 wrap gave me 1.0Ω. It going to take a big wick and/or a lot of wraps to make 2.0Ω.

    Looking for the VV Gripper without PWM.

    The TI PTR08100W is a Buck regulator (higher voltage "bucked" down to a lower voltage) so it would require 2 batteries. It also requires several external components to operate properly. Pretty much impossible to put into a Gripper. SmokeTEK (not SmokeTech) makes their VariCool box mod using...

    Need a good 18650 mod to run low ohm atomizers

    Having a calibrated meter does not null out the inherent internal resistance. You must still subtract the resistance or zero the meter. If you touch the leads together and it says anything other than 0.0, you're doing it wrong. The error could make all the difference between a safe coil and...

    Need a good 18650 mod to run low ohm atomizers

    Need a good 18650 mod to run low ohm atomizers

    Did you subtract the resistance through the leads and meter? ;)

    Looking for the VV Gripper without PWM.

    What resistance are you using? If you can go to a higher resistance then you can gain some adjustability and get ride of the burning.

    Question about battery safty

    Not true. No rest time is needed for regular usage. About the only reason to let your batteries "rest" is to gauge self discharge. If one wanted to, you could measure voltage off the charger, and again after a specific time period of your choosing (many hours, even a day). Then you have a...

    28 ga a-1 kanthal

    I received mine yesterday. You guys are great. I've been working with 33awg and have yet to get a SS wick Phoenix setup to work right. With the 28, 15 minutes after receiving it I was vaping a 1.0 ohm coil in the Phoenix. It was super easy to setup and works great. The downside is that the...

    Gripper Discussion

    JMHO, proper function and measured accuracy are two completely different things. Realistically, the whole Vrms/Vavg argument is just a state of mind. Tell your mind that the number on the display is a meaningless arbitrary number and dial to taste. If the displays on VV devices were 1-10, I...

    measuring with a syringe

    Also in the FWIW category, using 100mg Nicotine cut down to 18mg in a 5mL batch: +/- 1 drop = 0.35mg/mL, or ~2%, error. Now common sense should tell you that a 5ml batch with 100mg base is not the best choice to minimize error, but I can live with 17.65-18.35mg juice.

    measuring with a syringe

    FWIW, I measured ~90*F PG out to 58 drops/mL from a pipette. 1/58 = 0.0172 mL/drop. +/- 1 drop in a 5ml batch size = .06% error. Much, much, less for larger batches. Accurate enough for me. ;) I usually make batches of 120mL and don't use a syringe smaller than 5ml with .2mL graduations (...

    Could you shorten a Zmax to a shorter 16450 16500 size?

    With a professional machinist and a good lathe....yep.
