    Internal usb charging; best/safest method?

    Almost forgot to update this. Got the new protection circuits and soldered one up. So far it is working great. Tiny little thing it is. Thought it was going to be bigger. Will see what happens when the battery gets down to 3 volts. This booster is going to want 4+ amps on the input side at that...

    Madvapes vv box mod + LED??

    Not really sure exactly what you building. usually anywhere after the switch if you want it to come on only when vaping.If the control pin is used to turn the regulator on then after or the output of the regulator is where you want it. Before the switch it would be on all the time. Not a good...

    Madvapes vv box mod + LED??

    You just need to add a resistor to the led. Doesnt matter what side. for VV i would figure the resistor for the middle voltage. So if the vv goes from 3 to 6 volts i would figure the resistor for 4.5 volts. here is a link to a LED resistor calculator.LED Resistor Calculator

    Ideas Anyone?

    You can get a Ti launch pad kit for less then 5 bucks. Cheapest way to program a chip that can run the LCD but not the easiest to learn.

    Modding w an eGo pcb...

    A year or so ago a guy did some of these, should be a thread around here somewhere. Not going to find a lot of folks doing this since you can just buy a ego T MOD made for 18650's for 10 bucks. Joyetech eGo-T battery MOD control unit - Joye eGo-T spare parts Heaven Gifts Tubes are $5.50 extra...

    Question

    Depends on the battery really. 1.5C , C = capacity or mAh. So a 3000 mah battery would be 1.5 x 3000 = 4500mA or 4.5 amps would be the max discharge. 4.5 amps is plenty enough to vape off of.

    Newb Switch question

    Normally closed , Means that the switch will let power threw when not pressed. Or it is on unless the button is pressed. When the button is pressed the switch is turned off. Normally Open means the opposite the switch is off when not pressed and on when the button is pressed. Normally Open...

    Newb Question about capacitor...

    usually a mix of both ceramic and electrolytic are the best at filtering noise. Since your more then likey going to be powering the regulator straight off a battery it doesn't matter much, since batteries don't produce a lot of noise. If you were powering the regulator off a wall adapter then...

    Newb Question about capacitor...

    Looks like a ceramic cap there so it wouldn't matter what way it was put in. Caps that have to be put in with the correct polarity like electrolytic caps , the positive leg( wire) on the cap is always longer then the negative.

    Batteries for Box Mod

    Series wont work with the circuit board. Might just fry it. But yes your right series doubles the voltage parallel double the watt hours / or mah rating , In turn doubling the vape time.

    Batteries for Box Mod

    It could be done. You would need to make sure the batteries are the same voltage before putting them in parallel. The circuit board the switch is on has protection for the battery so you would need to use the whole circuit board in the mod.

    Internal usb charging; best/safest method?

    Yeah i for sure got to change my design since the one i planned on using was round. Not too big a deal i might beable to squeeze it in with no major changes. 3 amps would work fine for a unregulated mod. If you going to boost to 5 volts, you can use over 4 amps on the input side of the...

    Meter with low voltage buzzer

    I had one first thing i did was cut off the buzzer because i just wanted the LED readout. Still use it from time to time but it has lost a line in one of the digits. I guess cause i operated on it.

    Internal usb charging; best/safest method?

    That is exterior protected here is a link to better specs http://www.ayaatech.com/shop/?type=detail&id=416 Adding resistance on the battery side did make the PASS PCB work. hooked about a 6 foot piece of 22 awg to the battery holder and then to the PCB. ( no Nichrome on hand ) If i switch the 6...

    Internal usb charging; best/safest method?

    The bottom one doesn't work with my CGR18650CH Panasonic's Top PCB does work. If for short Circuit it has exterior / external short protection the PCB should work with IMR's. At least i am 98% sure going to order some of these for single cell Protection Circuit Module (PCB) for 3.7V Li-Ion...
