5 volts does vape better

MichaelMurder

So with being snowed inn and reading all about rockets Flashlights, Roberts detonator, and well everything that hachi uses in the execution of atty's. I decided I was tired of swapping batteries all day long and 5 volts sounded like it was the way. thru reading i realized there's way too much risk in experementing with lithium batteries especially around my kids. And i thought about the usb pass throughs. One problem I have no idea about crap when it comes to electronics. Read a few threads on resistances, ohms, voltage and ampsand had a calculator thanks to johnnyjames.. Hit up radioshack said i had an electronic project i was wanting to try was pointed to a back corner of a store and this is what emerged kinda wished it was a little more flashy but hey not bad for a first try. Basically i just slapped it together.














Was going to add an on/off switch and i still have it but i wasn't sure if this was gonna work so i just skipped it. The LED is just to remind me it's plugged in, or on once i put the switch in. There is a monetary PTC switch which i'm sure you can see that activates the atomizer. Currently the LED is always on. But hell, Now i know i can do. It lol.

HURRY UP!!!

I was using the Atty Smasher connected directly to the 5v rail for the hard disk drive on my computer. Problem is, the 5v rail can put out something like 12 amps, more than enough to fry an atty.

Now, according to ohm's law, at 5V a 2.7 ohm atty should draw 1.85 amps, for a wattage of 9.25 watts. These things are made to run at ~4V, so dood the math:
4V @ 1.48A= 5.92 watts. 9 watts will produce vapor like a fog machine!

Let me know when your atty burns out...

I use a TI chip that is limited to 2.25A, less at the 4.2V I'm running it at. I have another TI chip that is limited at 1.5A, so it should be more compatible with the 6watts as designed.

However, it requires parts I don't have, and I have to order some before I can analyze the circuit.

Now, if Rocket hadn't bought up every single $1 flashlight in the US...

BTW, a simple explanation:

Voltage is the measure of the pressure place in a circuit, and current is the amount of electricity flowing through the circuit. Resistance is just that: resistance to the flow.
Think of this: a bucket or a barrel on a stool, with a hose attached and a nozzle attached to that.

The higher up the barrel, and /or the level of water in it creates pressure, which in a circuit is the voltage. The water flowing through the hose is the amount of current, and the nozzle is the resistance, with one important factor: in the barrel analogy, a higher resistance equals a smaller nozzle, providing more resistance to the flow. A normal atty is ~2.8-3 ohms for a nominal battery voltage of 3.7. The 5V rated attys are about 3.7, providing more resistance to the voltage. These operate at about 7 watts, higher than normal, and produce a bit more vapor.

Funny thing this is the atty i thought was burnt out it just runs at like 3.7ohms and the other runs at 3.

Hmmm...

I have noticed that before the attys give up, the resistance starts rising. I had one that measured 1 meg ohm! It shoudl work OK at 4.2, a fully charged battery, but will work well at 5v. Did it come at 3.7? Mad Vapes is selling 3.7 ohm attys right now.

I doubt it. it was one of the atty's that came with my blu starter kit. Trash in my opinion. not happy with it at all. still waiting on my 510s.

Pictures are up. Sorry about the quality.

I hope you are getting a true Joye 510 to start with. After that you can try the numerous other clones.

My guy is out but his prices are great, especially on Joye atties.

For me the whole 5V thing don't cut it, although many folks think they are vaping at 5V because the passthrough they bought says 5V.

Instead of volts let's look at WATTS (heat) with a Joye 510 atty.

Stock Joye batts produce about 4.2W

My 2XAA 14500 box mod produces about 6W (a nice step-up from stock)

My 2A PT (it's at almost 4.7V loaded) produces about 9.5W

I tend to use a lot of cheap juice. Late at night watching TV I'll usually go with the standard 510 batt, winding down time. The PT is good for the morning for that first blast of high nic unflavored juice. My box mod gets the most use especially when out and about or at work. It's quite small and very unobtrusive, has long battery life and hits well at 6W. The 14500 900mAh batteries it uses are relatively cheap, < $5 and will out last any over priced Mega Battery by a wide margin. They also will last longer (months), more charge cycles (longevity).

These things are easy and cheap to build < $7. The hardest thing is usually soldering the positive wire to the atty connector (you don't want to melt the insulting ring), buy a couple and get the sealed ones he has.

MadVapes has everything including batteries and charger. For about $25 you'll have the box mod, 2 batteries and a charger.

For plastic modding these are great:

- Harbor Freight Tools - Quality Tools at the Lowest Prices

And of course this:

And they always seem to have these meters for $3 (good enough for our stuff), I have one for a back-up... seems fine.

My box mod is similar to MadVapes. I used a RS switch and recessed my atty connector into the box, it makes it more compact and stronger for when you drop it. I also used the existing hole in the case to flush mount a blue 3mm LED. The draw was a bit stiff so I drilled a small air hole in the back. It's really a nice small, bigger battery mod. A 510->901/KR808 adapter makes it very versatile. My next one will have a small charging circuit in it, so I can charge without opening/removing and use it as a pseudo PT also (keeping the battery always topped off).

Stealth baby, with more WATTS and hours of solid vaping. The perfect first step-up mod.

LOL it's what i made but smaller and battery operated nice. I'll take a look at it

Rocketman

Now, that's a couple of nice box mods. Michael that's not bad for a first time. I bet you end up with a dozen of these before summer Each one gets better.

I'm sure someone will think some other mod is better, but I'll tell you -
part of the taste you will get vaping these will come from the fact that

YOU MADE IT.

Rocket

Stehle

I want one!

(I can't wait for the shakes from the stroke to subside enough, so I can get busy on one!)

My hats off to both of you!
