Suggestion: TI PTN04050C
Exactly my point. If you use a pot instead of a resistor, it's now infinitely adjustable. This should be built into any board that MV produces. -
510 5V Passthrough with 2A USB Power Supply
It wouldn't be worth it to sell them. You can make your own for only a couple bucks. You can get all the parts you need from madvapes except for the USB cable, and you can get one of those at most dollar stores. It's pretty much the simplest soldering job you'll ever do. -
Suggestion: TI PTN04050C
If you're making the boards yourself, it's just as easy to make them adjustable as it is to make them fixed. -
LDO 5 volt, 3.0 amp regulator ??
If you're talking about the TI booster boards, you can buy them from Digikey or Mouser. They work well enough - it's what Nuck uses in the fistpack. -
New to modding. Head hurts. Mind Boggled. Need Help!!!
I'm going to make the same suggestion I made the last time you asked - A 3C or 3D flashlight mod. You could do a 3AA mod, but you'll probably go through a set of AAs per day, whereas a set of three D batteries should last nearly a week. It's cheap, simple, and can easily be made waterproof...- candre23

Trying to find a 5V switching regulator
5V switching regs able to handle the current we need are few and far between. The TI booster boards will do it, but they're pretty expensive. Switching power supplies require (comparatively) large caps and coils, so you can't make them on a single chip. The circuit isn't terribly complex, but...- candre23

LDO 5 volt, 3.0 amp regulator ??
Honestly, I don't know what to tell you. 801 attys are fairly high resistance (around 3.5ohms) so you should only be pulling 1.5A or less. I haven't used these specific regs, so it's possible that there is some limiting factor for these parts. But considering that a large percentage of the... -
510 5V Passthrough with 2A USB Power Supply
I finally got fed up with the constant blinking and having to unplug and replug the PT. I hacked the USB cable off and made my own PT. No electronics to go funky - just a 1xAA box, a horn switch and a 510 connector. Works great, and I know it will never go wonky on me. -
LDO 5 volt, 3.0 amp regulator ??
If a reg is cutting out, it's probably going into thermal overload and shutting down. The way a linear regulator works is by taking any voltage above the setpoint (in this case, 5V) and wasting it as heat. That heat needs to be removed from the device, or it builds up and the chip will shut... -
Tickets backed up from the move?
I don't know about support tickets, but the guys are definitely back to work because I placed an order this morning and already got a notification that it shipped. -
LDO 5 volt, 3.0 amp regulator ??
Amp rating. :P 2A should be fine for most situations. A 2.3ohm atty (the lowest you should be using at 5V) will pull 2.17A, but considering you're only using it for a few sec at a time, it shouldn't overheat. If you're using higher resistance attys, then the amp load goes down and you're... -
LDO 5 volt, 3.0 amp regulator ??
Exactly. You don't want to use LR attys on anything above 3.7V. LR attys have a short enough lifespan as it is. -
So, we're moving -- 6/27- 6/28 :)
So, is this your new home? 18631 Northline Drive, Unit E, Cornelius, NC 28031 - Google Maps Not bad. Good luck with the new digs! -
510 5V Passthrough with 2A USB Power Supply
Mine has gone from an occasional annoyance to a constant one. I rarely get more than half a dozen drags before something funky happens. Sometimes it happens on the first drag, sometimes only after a few minutes of use. Bizarre modes I've experienced so far: Solid light until unplugged, no... -
510 5V Passthrough with 2A USB Power Supply
Any non-LR atty will be fine. Attys get hot at 5V, it's just the nature of the beast. -

The " BUZZ " VariVolt Pv's coming SOON !
This is both true and misleading. If you're measuring efficiency as % of battery output that goes to the load, you are correct. However, if you measure efficiency as the % of extra energy (the voltage above your setpoint) that is wasted, then linear regulators are as inefficient as you can... -
The " BUZZ " VariVolt Pv's coming SOON !
Yes. Regulation doesn't change capacity. If it were PWM regulated it would have a longer runtime (due to effecient regulation) but the buzz has a linear regulator. If you had three setups with identical batteries and identical loads - a single battery, two stacked batteries, and two stacked... -
Vapors Take Caution

The Absolute MaxX from Absolutelyecigs.com - (Should) be better than the ego/riva!
Actually, it was assumed that the 4.2V claim was gimmicky advertising and that it ran at 3.7V (unlike the ego/riva that runs at 3.2V). As it turns out, it's not even a 3.7V device, but 3.2V just like the others. As it stands, the only true 3.7V ego "clone" is the bauway/hello 016. Everything...- candre23
