Wireless QI Charging Mod - Evic/Leo/Ego-C [Evic done here]

[qwertylesh]

Hi Guys,
I would just like to show off a mod I did today, its nothing flash, simply re-purposing a Phone QI clip into a charging sleeve for a joyetech evic.

I've been pottering about with this idea on some Australian vaping forums for a while, sourced all the parts to try it out.

I made sure the goods I purchased was WPC 1.1 version standard, after reading that the original 1.0 standard had a safety flaw where it could heat up foreign metal nearby the transmission/reception copper arrays (clearly an issue for metal tubes right?)

After trying the WPC 1.1 hardware extensively so far, it appears to be quite perfectly safe.

Less talk, more pictures!

I think the mod is very simple for anyone keen to do for any ecig or other usb device where the charge circuitry is integrated.

Its possible to perform the mod for non-stacked devices which doesn't have usb integrated, but would involve building a charger/regulator into the sleeve and building a specific tri-gate male-female atomizer-battery head. tricky, possible.

A further extreme which could be nice is to perform a mod where the array from a mobile battery is installed into the ecig behind say for example the evic fire button plastics, saving lots of space. more research into where the array could be soldered to the usb pcb port pinout would be required and space becomes an important factor.

If I try any of these more difficult mods I will post back here

Nice work there. I'm getting a Qi charger for my phone this week and was curious what it would take to charge something else. I look forward to your possible undertaking of the more challenging version of this mod too.

qwertylesh, I had a bash at something similar a year or so ago - with Nintendo inductive chargers. The idea has a lot of promise, I think.

Hey slopes.
I have the nintendo wii chargers too, I took one apart before buying new high powered stuff, the nintendo ones were too weak, for AAAs and stuff, something like 2.4V 400mA.

Phone stuff is much better 5v 1-2A
They charge nice and quickly

That lighter mod looks awesome, still using the wireless on it?

Ive been doing some minor revisions to my initial sleeve, and have began prepping another, I like the tech so much i decided to buy another evic, so now I have two evics to build sleeves for.

Last night I was checking out those provari wraps made of 3M scotchpaint, that stuff looks mighty nice, I will very likely end up swapping the cheap (electric tape ) material for mostly scotchpaint where possible

For now I have simply began using much better usb molds and learning which pcbs are possible to bypass altogether.

Once you get past testing, replacing the duct tape with adequately sized heat shrink tubing would be a better way to keep it on there.

I did the leather sleeving in the end.
(one on left has been re-sleeved since the pic below and now is full size & nicer)

I will need to work on re-enforcing the quality of the solder point to the micro cable.
I am thinking some kind of silicone or something to ensure the solder doesnt break off the pcb (inside the leather)

Apart from that the quality is great.

I might look into getting a better pad some time in the future:
