Thank you for this tutorial Highping. I have created your mod myself. As requested I have put in a picture. I think now that I have a new MOD, I need to buy a new camera. I tried everything to get clearer pictures.
Couple of different things on mine.
I used a larger switch. I wasn't really worried about the amp rating of the earlier switch, but saw some other people were, so wanted to try this one. It is rated at .5 amp. I'm not an electrician so have no Idea what the current rating should be. But I think .5 amp is larger capacity than 50 mA. In order to make this modification, I had to remove the small cover over the on/off switch, and remove one of the pegs holding that cover. It barely fit, but I got it in there.
Found a 1/16 brass tube at my local True Value Hardware store. They also had aluminum and copper. I probably should have went with aluminum, but had not read about the juice changing color from oxidation, until I already had made my purchase. Doesn't really matter, it will not self feed with my VG juice anyway. The inner diameter is too small to push thick liquid through. It feeds fine with pg. I had a little left over from when I started.
Also I used a flashing LED. Just personal preference on that one.
One more thing I would like to add to help with the solder challenged. I too am solder challenged. But one thing I did not see in advice of soldering was using a good flux. Do Not Over Estimate the ease of soldering with a good flux. The solder will just run. Remember when soldering, it's Not "the bigger the blob, the better the job." Use just enough to get a good thin hold. Solder is amazing. It will do the rest.
P.S. I guess I need to change my name. I no longer have an eGo. One battery died because of the switch being accidentally pushed in my pocket. Must have been awhile, because it was burnt up completely. But no problem right? I have a spare. Well my charger gave out the same day. Glad it did. It rushed me to build this MOD, which I love more than my eGo.
Thanks again for the instructions.
Everyone happy Modding.
