So you preserved the original eGo electronics.. eh?

How is the perceived performance now? I'm interested in your take on the power reduction associated with the eGo electronics and their "poor man's approach" at voltage regulation.

Yes it`s still the original eGo electronic. The performance is the same I think... It`s putting out 3,6V. but now I dont have to charge it every day
Electronic is not my strong side, so I have to learn from the best :) Are you op fore it ? :D

@asdaq The button best operated by the tip of the thumb, takes a bit getting use to.

I have some Ti chips coming , so there is a lot to learn. :)

Nicely done:)

If I had a lathe I would have come up with a similar design. I had to settle for a boxed eGo running an 18650.

There is a slight difference in performance when operating without the PCB, but it is nothing to write home about. A set regulated voltage of 4.2V (unloaded) and the difference is indeed noticeable.

Considering the "poor man's" approach to power regulation, I would have to say that it is pretty efficient (size wise) but I don't have the required equipment to endorse my claim. Owning a plethora of devices, the eGo is still one of my favourites. The latter could very well be subjective.

Switched,

Just an FYI: Put some new traces up here: http://www.e-cigarette-forum.com/forum/joye-510/65055-battery-voltages-surprise-37.html that show how the "latest revision" of the eGo PCB (yes, there has been a change) handles voltage regulation.

Kinda interesting.

What is the base unit you are using for this mod Minus? How did you attach the + & - at the top of the base unit? Any more detaled pics? I would love to try this mod as I like the cone not only from an asthetic perspectice but performance. I think the vapor is just a tad warmer as the atty is somewhat insulated. I have an 18650 mod and often find myself reaching for the eGo. I really like the vape on that little thing even though my mod is pumping out higher voltage.

@Rockproof

My base unit is the eGo, pulling of the battery case and battery., keeping the contact and wires.IMAG0119.jpg

The tube is made of stainless steel rood, drilling out from one side 13,50mm. and the other side 18,7mm. 72mm. in depth, and the thread is 20mm X1,5 I would have used 20mm x 1 if i had the bit.

For the + i made a plastic tube Ø13 X 7mm with a 1,5mm. hole in the center for the wire, and a thin plate with a small hole to soder the + wire to. The - is wrap`d around the plastic tube, and the tube is glued to the contact.

IMAG0126.jpg
the contact and the tube is just pressed together with a tiny drop of lock-tight
IMAG0127.jpg
The spring is just glued in the center with 5 min. epoxy

hope this is what you wanted? :)

Wicked Minus. I didn't know you had a custom tube. I thought you actually MOD'd a MOD (like a Silver Bullet). Seriously, if you want to make another, PM me with a price. I would love to have one of like that pictured (unfortunately, I would have to guess you are in Canada or the EU based on the use of metrics?) that piece. I know if the switch ever went bad, just dissect an eGo head a viola...Is the eGo head press fit in or soldered?

I don`t think I´m going to make more than this one, reason i`t took 6 hours to make 4 of them is at the lathe. And me being in a wheelchair it is quite a challenge :)

The switch is press fit in. and yes I`m from Denmark

Have been using it now for 3 days, and the strange thing is that, after 1 day ( like a normal eGo ) the 3000mah battery seems flat, but when I take battery out and insert it again, it vapes like a champ again. It has been like this the last 3 days. I wonder if there is some kind of monitoring of the use of mah in the eGo electronic ?

Just to eliminate the possibility of a battery problem, check the protection circuit board for looseness. There is a small metal strap spotwelded to the negative end of the cell but it is only soldered to the circuit board. One accidental drop to the floor can break this connection. Pressure on the end of the cell may make contact, sometimes. This will show up as an intermittent failure. Cell can have a charge but no current will flow until you move the bad connection and re-clean the contact.

Being that your in Denmark Minus, and I don't have a lathe, I decided t0 build my own from a dead eGo batt yesterday. I decided to bypass the reuse of the eGo swith and just went for using a standard switch, the head atty+head unit and cone (as the cone design is really what I wanted in tnhe first place. Thanks for the idea Minus. heres my 18650 eGo mod.
