    PCB Experts: OKR-T/6 Custom PCB - Recomendations/Critique

    Looks pretty good, You could make it smaller width wise by using SMD resistors but if you got the room no big deal. I have a couple of footprints i made up for that module if you want them one is rounded and the other is square. Would fix your double holes, plus it makes soldering these jokers...

    Blu Charger on 510 Battery

    Yes switching the wires around would make it work with a 510 batt

    Just For LM2596 Users

    Mine creates static on the radio also but only seems to be on the weak stations. Adding capacitors might clear it up they are good at filtering noise out of the power. If i am remembering correctly ceramic caps are good at filtering lower end noise and the electrolytic caps are better at the...

    Just For LM2596 Users

    What i got from reading that is even though the wire temp will be lower per a mm with the 28g wire the vapor is is better. But yes if you wanted to match wire temps it would take more amps

    Just For LM2596 Users

    I read that 6 coils is about 1 ohm so around 12 coils to get around 2 ohms. 2 ohms is 2 ohms no matter the thickness of the wire it is going to use the same amount of amps. OHMS LAW says 2 ohms at 5 volts would be 2.5 amps.

    Watt meter

    Since that watt meter senses off the ground you could run into trouble if you plan on using the case or tube as a ground. It needs to be a isolated ground coming off the regulator going threw the watt meter to the atomizer connector for a proper watt reading. Since the DNA is isolated already in...

    Desktop Unit ???

    The problem with having the vaporizer so far away from the tip is it will lose a lot of the heat and some of the vapor by the time it gets to your mouth. That has a profound impact on the quality of the vape. It is almost like your vaping air. This is one of the main reasons most of the hookah...

    Watt meter

    You have to run the power threw the meter. Very similar to a amp meter more so then how you would test for ohms

    Cheap Chinese Knock-Offs

    Actually the first patented Electronic Cigarette was by a guy named Herbert Gilbert way back in 1963. He was from Beaver Falls, Pennsylvania , USA. Although it never took off back then it does seem he was the first by about 40 years. Since it is passed the 20 years a patent protection lasts you...

    Q: Homemade PT is weird o_0' (Laptop psu)

    18.5 volts is a bit high to be vaping at. You are more then likely tripping protection on that adapter is the reason it seems like it is pulsing. A 2.3 ohm atomizer @ 18.5 volts would require 8 amps. Well passed the 4.9 amp rating of the adapter. So when you hit the button on the PT it trips and...

    Question on OKR-T Mod

    These type regulators are almost always used to power logic circuits. Reason the caps are required is switching regulators are quite noisy. Caps are not really used for there capacitance in this situation, but for there filtering ability. So they are used to filter out the noise that would other...

    How Accurate?

    I just checked a couple and they are correct. But it is power/watts not amps Here is a ohms law calculator if you want to check some yourself http://www.the12volt.com/ohm/ohmslawcalculators.asp

    battery life -- booster vs LDO

    The booster will still beat the LDO. It comes down to efficiency and LDO's are not very efficient. The best battery life would be using a Buck switching regulator and two stacked batteries that set up can get you over 90% efficient. Most of your good boost switching regulators get in the 80%...

    ego wiring help

    Not sure exactly what you have in mind for the mod. But the two wires going to the battery would hook up to a replacement battery. It is as simple as that. You could even keep the USB to charge the new battery. If your plan is to make it a True passthrew with no battery it gets a bit more...

    A couple of battery questions

    The 6 amp would be more then enough. I doubt you will see much more then 3 to 3.5 amps with the DNA booster on the input side. I use that same protection PCB on my vv booster that can run up to 24 watts. The main thing your wanting by adding the PCB is the short circuit protection. So if by...

    A couple of battery questions

    Putting the batteries together and wiring in parallel would not be a problem. But these are Unprotected battery packs that require you to add a protection PCB. I would also heat shrink or tape the battery pack rather then the DNA module. Not sure how hot a DNA gets but it is usually a good idea...
