Rocket makes another Box Mod

[Rocketman]

This one is a pass thru. It has an eGo connector pressed into the front of an aluminum die cast box, and a 510 batt connector on the bottom for charging, or pass thru operation.
Using a Sanyo 2600, tabbed Li-ion cell, 18 ga. wiring, a horn switch, and a 6 amp protection circuit board. Oh, and a meter. The meter is wired directly to the eGo shell and center pin and indicates LOADED VOLTS at the connector, not cell voltage.
Will deliver 4 volts LOADED to a 2.8 ohm carto, and 3.9 to a 1.6 ohm Dual Coil. Slightly higher while on the charger. A little 2-part epoxy was added to stabilize parts and insulate. A 1/4 inch vent hole was added next to the charge connector.

Sweet... nicely done.....

 

[Rocketman]

And the schematic (hand drawn). All current carrying wires are solid 18 ga.

Nice Rocket !!!

Scary on the inside, but really nice on the outside,
Good work there Rocket.. me likes!

Ventilation? Magnets on the cover so when it blow, the cover will fly off. Hopefully away from you...

 

[Rocketman]

Naw, cover should stay in place. If she blows, and the 1/4 hole in the bottom ain't enough it will push the meter out. Hopefully not shoot it too far so I can't find it, it's a cute little meter

It has some epoxy in it to keep things from moving around when I drop it.


OK, so you got me worried. I drilled a few 1/8 inch holes in the bottom around the 1/4 inch hole.
That should save the meter

Very nice

You going industrial duty on us Rman??

Got all these boxes, what's a guy to do?

 

[nicotime]

Got all these boxes, what's a guy to do?

Oh yes...the agony!!

 

[breaktru]

Real beautiful Rocket,
This would put the icing on the cake:

 

[lynch]

Awesome mods Rocketman......more ideas

 

[jcamacho]

Way to go Rocket! Enjoying retirement I see!

 

[Rocketman]

This would put the icing on the cake:

Thanks, now I got to make another one, Yeah, thanks

@jc: mostly yes

 

[HyOnLyph]

Uhm.... a little polish wouldn't hurt. I'd love to see what one looked like all polished up.

Could this be built to reach 5 volts? Did you already post a parts list? I think I might try to build one of these.

Got all these boxes, what's a guy to do?

 

[Rocketman]

The Die Cast Box I use doesn't polish up well. The casting isn't clean enough and the shine doen't last. I don't mind the dull look.
To get the best prices on all the parts means buying from several places, some with slow boat shipping, most with shipping charges. If you watch when you make orders and slip in a few extras then you can accumulate the parts and spread the shipping out some.

I don't do 5 volts. I built it as a 3.7 volt big battery mod, with an external charger, that can work stand alone (18650 battery) or as a pass through (with an eGo 420 ma charger),only drawing charge current from the USB, not vaping current. This should be safe for driving from a computer USB jack.

I'll give a parts list and where I got them, but I usually buy from these places anyway so shipping doesn't add much too the cost. Buying one part from each vendor would add up quick.

PARTS:
The Box, MPJA.com,
the Sanyo 2600, tabbed cell from ebay seller in Califonia,
the protection board (has two mosfet switching chips) from Deal Extreme,
the switch from All Electronics,
the eGo connector, and 510 connector, and eGo charger from Heaven-Gifts,
the meter (1S-6S) from ebay seller in China,
assorted wire, solder, epoxy.

TOOLS:
a hacksaw blade,
a needle file set,
drill bits,
rotary stones all from Harbor Freight.
an adjustable soldering station from MPJA,
and a battery or electric drill.

USER SUPPLIED ACCESSORIES:
USB power source, for me it's at the lower left of my browser,
a USB extension cord 2 to 20 feet,
suction to produce and collect vapor

Keep up the excellent work Rocket!!

Skip the polish, The rough look has it's own beauty.
Ever thought about making a juicer?
That will be my next attempt, Keep looking at my
180 amp welder and my 200mph leaf blower... might work...
have to use low nic juice, don't want to overdo it.

Can't get it like the one on the left?

 

[Rocketman]

Nope, the U.S. Die Cast box just doesn't want to take a shine like the Chinese Aluminum Flashlights
