Kam's EL-Cheapo Two Battery 5v 5amp mod idea.

Digikey offers a 5 volt constant linear Low-Drop-Out regulator that requires minimum 6.5 volts. for 50 cents a pop.

I think that one of these would be nearly ideal for anyone who wanted to implement an el-cheapo five volt regulator for a pair of "Stacked" batteries.

This device has three pins, vin, vout, ground.

Take two nylon washers of the right diameter (about the inner diameter of a mech mod)

take a metal disc slightly smaller than one of your nylon washers. Drill out one of your washers until it is big enough to fit around the contact pin to your atty. Glue the metal disc to the washer. This will form a contact setup that won't short to the mod body.

Solder vout (the tab and middle pin) to one metal disk. This is now your output and "heatsink."

solder the leftmost pin to a metal side tab that will brush against the body of your mech mod. This is ground.

take the other nylon washer and glue another metal disk (can be smaller than the first disc to it. This will be your battery contact. Make a wire from it to the rightmost (Vin) pin. Glue this all together to form a "sandwich thingy"

make your mech mod a bit longer with its extensions, sandwich that baby in...

and for a couple dollars, you got 5volts constant without needing to burn power off with some resistor thingy. 5 amps max.

your about 2 yrs late

That woulda been the cat .... for many who vaped 5v box mods then now with variables so inexpensive not much interest in constant 5v but still hugely awesome..

That would be cool to use as a 5v kick on a mech with a partition board and a board pin.
Sandwich it between two partition disk use the spring pins for ground golden ease..

Eh, I didn't really try to convey that this was some sort of super creation of my brain, and I'm honestly not at all suprised its been done before.

But I was reading the battery mods thread and I read up there somewhere about folks taking their mods and using washers and graphite to achieve a voltage drop inside the mod body and I was thinking.

1- No.
2- Use a regulator they are super cheap
3- Ugh, efficiency.

So, I guess I just made this if anyone cared to have a quickie reference to a cheap, commonly available part that could be used for such a thing, wether stacked in the disc like setup or glued to a heatsink inside a box mod, whatever. It requires a soldering iron but very little knowledge of electronics otherwise to use.

In, Ground, Out, heatsink to the center pin with solder and some thermal mass and you'll be golden. Given the amount of time people vape on an E-cig I seriously doubt that the reg would even get altogether that hot, so it probably doesn't need all that much thermal protection anyway, these things if the datasheet says it will support 5 amps max really mean that it can with proper cooling supply 5 amps all day every day for years and years and years.

Yeah its uber sweeeeet and doable for many mechs why I added make it easier parts
If you posted this a way back you woulda had 1000 people trying it 5A was huge at a time...
all under 5 bucks 5v regulated vapin 1Ω -- those new subtanks vape real nice @1.2Ω
much better than a 15w kick for the costs and you can build 2 of them for 5 bucks..
